==What about Coblation==
The section on "Bipolar Radiofrequency Ablation" refers the reader to "Coblation Tonsillectomy", but this article does not exist.

==Growing back?==
-What's the source on the tonsils growing back after removal?  That's really very interesting.    --[[User:FMephit|FMephit]] 05:11, 3 Dec 2004 (UTC)

::I think that's a confusion of the tonsils with the adenoids. The adenoids can grow back after an adenotomy, IIRC, but for sources on that, STFW... [[User:Dabljuh|Dabljuh]] 21:42, 17 January 2006 (UTC)

:Tonsils can in fact grow back if some tonsil tissue was left behind during the surgery.

== Citation concerns ==
The section on ''Methods of Tonsil Removal'' was lifted wholesale from this site (http://www.entnet.org/KidsENT/tonsil_procedures.cfm) listed in the ''External Links'' section without appropriate citation.  Is this OK?

== Pictures ==

I personally don't think that the current picture of the article is very useful unless we have a "before" picture to go with it. Maybe someone who has very swollen tonsils could take a picture of them before they have them taken out and add them to the article. I think that would greatly improve the visual aspect of the article. --[[User:Emery|Emery]] 23:26, 10 January 2007 (UTC)

== Post-Op diet recommendations ==
I've removed the sentences which claim that North American physicians recommend a diet of soft foods while in the UK "crunchy" or "rough" foods are recommended to keep the tonsil beds "clean".  It was completely unreferenced and counters what is suggested in the references I'm finding.  The only mention I've found in texts to anything but soft foods being recommended was a study in 1992 which concluded that eating soft foods or rough foods after a tonsillectomy had no impact on recovery time, pain medication, etc.  Without some reference to the differing advice between the UK and the US/Canada, the information doesn't belong here.--[[User:RadioFan|RadioFan]] ([[User talk:RadioFan|talk]]) 14:38, 25 April 2009 (UTC)

I think it is important to note serious side effects such as a loss of taste, or metallic taste in the back of the mouth due to nerve damage caused during tonsillectomy.

The source suggests that it the complete tonsillectomy is at least 2000 yrs old. Not 3000. The source does use a quote from 1000BC that describes a partial, not complete, tonsillectomy. So in principle, surgery on the tonsils is at least 3000 years old and a complete removal is at least 2000 years old.

== Just had my Tonsils REMOVED!!! ==

Hi

I have just had my Tonsils removed 6 weeks ago, before the operation I was searching the net for information, but did not find what I was looking for, so here is the REAL truth about my operation on the N.H.S !!!

I am a 40 year old male, fit and healthy, do not smoke and not overwieght, I attend a gym 3 times a week. I had my Tonsils removed to hopefully stop me from Snoring!!

I was told I would need two weeks off work after the operation, which was an overnight stay in hospital, surely it can not be that bad I thought to myself??. I awoke after the operation with hardly any pain, but slowly during my overnight saty it became worse, I was taking pain killers and anti biotics every 6 hours, I left hospital the folowing morning and felt really drowsy..I could not return to work.
I was still taking loads of pain killers and anti biotics given to me by the Hospital, which I had to take every 6 hours for the next 21 days!!..after 5 days at home I returned to work..M<ASSIVE mistake, by day 7 I was in total agony, in all fairness the Doctor told me it gets  worse about 7 days after the ooperation, and man was he right!!!..all I could swallow was water and soup which was total agony, this went on for about 2 weeks, I felt terrible. Finally after approx 5/6 weeks I am now able to eat normal food and also taste the food.

All I can say is take 2 weeks off work to recover, and expect plenty of pain!!!..I lost 2 stone in 6 weeks with not eating correctly and had no energy whats so ever. 

But YES I have stopped SNORING so my Wife says it was well worth it.  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/81.144.178.190|81.144.178.190]] ([[User talk:81.144.178.190|talk]]) 07:25, 1 June 2010 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

== Tonsillectomy and voice-change ==

This article does not cover the most talked-about after-effect of a tonsillectomy - possible voice change.

*I agree that this content is not appropriate for this article. However, I also sympathize with the need for Wikipedia to develop and eventually have a process for summarizing research. The reason why this content does not belong in the article is because reporting the outcomes of primary research in a correct way is so difficult as to be nearly impossible in Wikipedia's medical articles. I could support an experimenting in starting a new article, something like "research on tonsillectomy", and clearly marking that article as a history and summary of research outcomes which no one should use to inform health decisions. Such information could be useful to track things like the history of medicine, social issues related to research, and general trends in research. I am not aware of good examples of such research articles existing. It would take a lot of work for someone to talk through the model of this, but this is where we are in Wikipedia. I can think of no way to go into this much detail on a general medical article without inappropriately communicating that there is some health insight to find in primary research, which would be a mistake.

I am not persuaded that primary sources should never be cited. We teach medical students that where there are no relevant systematic reviews we look for primary evidence as the next best alternative. I am also not persuaded that "position statements" are particularly reliable as they can simply reinforce current opinion and ignore evidence. In relation to long term effects of tonsillectomy the Population of interest is children, the Exposure or Intervention of interest is tonsillectomy, the Comparison should be children who did not undergo tonsillectomy, the Outcome is subsequent illness or death years or decades later (not biomarker measurements or physiological variables). We should first look for systematic reviews of RCTs (there are not any), then systematic reviews of cohort studies (there are not any which look at illness outcomes), then primary cohort studies (there are a number).[[User:TTM314|TTM314]] ([[User talk:TTM314|talk]]) 23:20, 16 May 2019 (UTC)

:::@Doc James: The claim that the long term impact of tonsillectomy on the immune system is still not fully understood was based on the fact that there are several literature reviews that found an association between tonsillectomy an certain diseases (Crohn's disease, multiple sclerosis and polio). Those literature reviews are referenced in the article. So I put it back, but now with the argument that some studies did find an association whereas other studies did not. By the way, you used terms such as "appear" and "unclear", so you basically admit that it is still not clear what tonsillectomy does to the immune system. I also moved the information about the association between tonsillectomy and polio back to the complications section. I agree that polio is not really a concern anymore as it was in the forties and fifties, but that association is a potential indication that tonsillectomy does compromise the immune system in some way. I also put back that the increased risk of tonsillectomy on attracting multiple sclerosis is "small but statistically significant and clinically important" because this is what one of the articles literally says.

I am afraid the cited source is very weak evidence as it does not measure outcomes of relevance to patients (illness, mortality) but instead measures levels of immunoglobulins; the follow up in most of the included studies is measured in months, not years; the combined number of patients in the 35 included studies is less than 2000. [https://www.ncbi.nlm.nih.gov/pubmed/?term=26055199] It is misleading to suggest this rules out any future effects of tonsillectomy on health.[[User:TTM314|TTM314]] ([[User talk:TTM314|talk]]) 23:25, 16 May 2019 (UTC)

Most recent figures from the US are 289,000 childhood tonsillectomies per year.<ref>https://www.cdc.gov/nchs/data/nhsr/nhsr102.pdf</ref> Median cost of a tonsillectomy in the US is $3585. <ref>https://amino.com/blog/tonsillectomy-cost/</ref> $3585 x 289,000 = $1.036 billion. Childhood tonsillectomy is a billion dollar a year industry. I would therefore suggest we should be cautious about accepting the views of the industry on their current practice. By contrast the Cochrane review states "It is clear that some children get better without any surgery".<ref>https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD001802.pub3/epdf/full</ref> This is illustrated in Analysis 1.1 which shows that in the five RCTs included, children assigned to the groups that did not undergo surgery averaged 3, 8, 3, 4 and 3 sore throats in the next year. Considerably fewer than previously. In good part this is likely to be [[Regression to The Mean]], which is of course one of the reasons we need RCTs.[[User:TTM314|TTM314]] ([[User talk:TTM314|talk]]) 13:44, 17 May 2019 (UTC)

==Summary==
Ref says "tonsillectomy for recurrent throat infections in severely affected children was shown, in a randomized controlled trial, to reduce the frequency and severity of infections in the 2 years following surgery"


This IMO is a reasonable summary:

"For those with frequent throat infections, surgery results in fewer sore throats in the following one to two years, but unclear long term benefits."<ref name=Oto2019/>

:::{{ping|Doc James}} {{ping|Ozzie10aaaa}} One of the main points of this article is that the benefits of tonsillectomy are very modest at best. Therefore it needs to be in the introduction like in the abstract of a scientific study. I agree with {{ping|TTM314}} that simply saying “fewer sore throats” is misleading. This is a medical article, so we really need to be careful, even in the introduction. I do not see what rule there would be violated, or what problem will be caused by mentioning a number or the fact that the reduction is minor. It would make the introduction more accurate by only adding a few extra words. And if we can say in the introduction for how long the decrease in sore throats persists, why can’t we say how big that decrease actually is? I also see some statistics regarding complications in the introduction, so why not about the reduction in the number of sore throats?

Even that Cochrane review you are talking about says “The odds ratio for CD following a tonsillectomy was 1.194, 95% CI 0.992–1.437”, which means a slightly increased risk of CD.

== Evidence for effectiveness of tonsillectomy for Obstructive Sleep Apnoea ==

I am concerned that the page as currently written misrepresents the evidence for tonsillectomy in Obstructive Sleep Apnoea

What Wikipedia says:
"Tonsillectomy improves obstructive sleep apnea (OSA) in most people."

What the evidence says:
Adults: no RCT evidence

Children: RCT evidence shows improvements in polysomnography parameters and in "quality of life, symptoms and behaviour as rated by caregivers". These are subjective outcomes rated by a third party in unblinded studies. 

It is also observed that half of children improve without surgery - so it is hard to see how tonsillectomy can improve "most" chidren since half improve anyway.

There is no evidence in relation to children with OSA which is not confirmed by polysomnography. 

There is no evidence relating to children aged under 5 years.

'''Exact wording of the Cochrane review:'''

''In otherwise healthy children, without a syndrome, of older age (five to nine years), and diagnosed with mild to moderate OSAS by PSG, there is moderate quality evidence that adenotonsillectomy provides benefit in terms of quality of life, symptoms and behaviour as rated by caregivers and high quality evidence that this procedure is beneficial in terms of PSG parameters. At the same time, high quality evidence indicates no benefit in terms of objective measures of attention and neurocognitive performance compared with watchful waiting. Furthermore, PSG recordings of almost half of the children managed non-surgically had normalised by seven months, indicating that physicians and parents should carefully weigh the benefits and risks of adenotonsillectomy against watchful waiting in these children. This is a condition that may recover spontaneously over time.
''
''For non-syndromic children classified as having oSDB on purely clinical grounds but with negative PSG recordings, the evidence on the effects of adenotonsillectomy is of very low quality and is inconclusive.''

''Low-quality evidence suggests that adenotonsillectomy and CPAP may be equally effective in children with Down syndrome or MPS diagnosed with mild to moderate OSAS by PSG.
''
''We are unable to present data on the benefits of adenotonsillectomy in children with oSDB aged under five, despite this being a population in whom this procedure is often performed for this purpose.

== Long term effects - immune function versus autoimmune conditions ==

I am concerned that the current version is being distracted by measures of immune function which are not directly relevant to patients.  

'''Wikipedia says:'''
"Tonsillectomy does not appear to affect long term immune function"
This is referenced to a meta-analysis of studies of biomarkers of immune function (Immunoglobulin levels - serum Ig's, SecIgA, cellular immunity, Ag specific Ig).<ref>Bitar MA, Dowli A, Mourad M. The effect of tonsillectomy on the immune system: A systematic review and meta-analysis. Int J Pediatr Otorhinolaryngol. 2015 Aug;79(8):1184-91. doi: 10.1016/j.ijporl.2015.05.016. Epub 2015 May 27. doi: 10.1016/j.ijporl.2015.05.016.</ref> But the fact that this is a secondary source is being given undue weight. It is a systematic review based on evidence from 35 small studies. Some studies included in the meta-analysis have no control group and are simply before and after studies, some are cohort studies. The total number of individuals in all the included studies was 1997, follow up testing was carried out at different time points but in most cases was less than a year (132 months in one study). This analysis is therefore not very long-term. It is much too small and too short term to compare future incidence of illness in children who have tonsillectomy and children who do not have tonsillectomy. In other words the study is underpowered to detect differences in disease incidence and is in any case only measuring biomarkers.

'''What the evidence says:'''
I would suggest that future incidence of disease is of more interest to patients than changes in biomarkers. We don't have long term follow up with any RCT of tonsillectomy. It is inconceivable that we ever will have RCTs with years of follow up. The best we can do is a (retrospective) cohort study of children who did have tonsillectomy compared with those who did not. 

There are three large retrospective cohort studies several orders of magnitude larger than the study cited above to support the suggestion that tonsillectomy may be associated with a higher risk of future illness. These appear to be being dismissed because they are primary sources, but they ask the right questions (about risk of illness, not biomarkers) and are very much larger than the entire 35 studies included in the cited secondary source.

One study included 1.2 million Danish children of whom over 40,000 underwent tonsillectomy, followed up for 1 to 21 years. This found a higher incidence of respiratory, infectious and allergic conditions later on in life in children undergoing tonsillectomy.<ref name="pmid29879264">{{cite journal|vauthors=Byars SG, Stearns SC, Boomsma JJ|date=July 2018|title=Association of Long-Term Risk of Respiratory, Allergic, and Infectious Diseases With Removal of Adenoids and Tonsils in Childhood|journal=JAMA Otolaryngology-- Head & Neck Surgery|volume=144|issue=7|pages=594–603|doi=10.1001/jamaoto.2018.0614|pmc=6145787|pmid=29879264}}</ref> 

An Australian study followed up 8583 children for 37 years: 1238 underwent tonsillectomy and an increased mortality was observed in those who underwent tonsillectomy.<ref>{{cite journal | vauthors = Mészáros D, Dharmage SC, Matheson MC, Venn A, Wharton CL, Johns DP, Abramson MJ, Giles GG, Hopper JL, Walters EH | title = Poor lung function and tonsillectomy in childhood are associated with mortality from age 18 to 44 | journal = Respiratory Medicine | volume = 104 | issue = 6 | pages = 808–15 | date = June 2010 | pmid = 20079616 | doi = 10.1016/j.rmed.2009.12.001 }}</ref> 

A study which followed up 179,875 Swedish patients who underwent tonsillectomy observed an increased risk of autoimmune conditions such as thyroid diseases, rheumatic diseases, inflammatory bowel disease and type 1 diabetes. The exact wording from the Abstract is: 

''A total of 179,875 individuals received a tonsillectomy in Sweden and 5357 of them were subsequently diagnosed with autoimmune diseases, giving an overall Standardised Incidence Ratio (SIR) of 1.34 (95%CI 1.30-1.37). For specific autoimmune diseases, 16 of them showed a significantly increased SIR, ranging between 1.21 and 2.97. The increased incidence was largely consistent irrespective of gender, age at operation, and underlying indications of tonsillectomy.
''

None of these three papers is utterly free from potential confounding but they measure incidence of disease and mortality, both of which are more important to patients than biomarkers (which have a more tenuous relationship to illness). All three papers are much larger, have longer follow up and more robust than the study which is currently cited in Wikipedia as evidence that tonsillectomy has no effect on the immune system.[[User:TTM314|TTM314]] ([[User talk:TTM314|talk]]) 22:48, 16 May 2019 (UTC)

:{{ping|TTM314}} I fully agree with you. I found literally dozens and dozens of primary sources that indicate that tonsillectomy compromises the immune system, so secondary sources (which are based on primary sources!) that claim that there is no evidence that tonsillectomy compromises the immune system are simply wrong, especially if they only look at immunoglobulin levels a few months after surgery instead of the incidence of disease decades later. Furthermore, in the article no explanation is given on why removing its entire first line of defence would have no negative effect on the immune system. But most importantly, it’s a big shame that every year, thousands and thousands of young children are mutilated and have their life and health put at risk, just to avoid one or two sore throats.

:::{{ping|Doc James}} I think you are missing the point. There are some good reasons to doubt the quality of several of the cited secondary references here. As TTM314 said earlier, the fact that immunoglobulin or whatever other levels do not change after tonsillectomy does NOT mean that the immune system is not compromised as it is the incidence of disease that ultimately matters. So yes, we can mention that the level of (...) and the level of (...) remain unchanged after surgery, but the conclusion that tonsillectomy has no negative effect on the immune system would be premature. Furthermore, that there are no studies that demonstrate that tonsillectomy negatively affects the immune system is simply not true. This article cites multiple secondary sources that found an increase in the risk of Chrohn's Disease and Multiple Sclerosis. Besides that, there many primary sources that found strong indications that tonsillectomy does harm the immune system. I know we cannot use them here, but secondary sources should not ignore them.

I'd add a more nuanced, but general public friendly statement such as "Of the available scientific evidence, roughly 9 out of 10 studies show that tonsillectomy has no effect on the immune system.

I think the following four points should be mentioned:

* Most studies suggest there is no correlation between tonsillectomy and certain biomarkers related to immune function. Some studies however, do show a moderate correlation.
* There is a lack of literature reviews on the link between tonsillectomy and the incidence of disease, except for multiple sclerosis and Crohn's disease.
* The available literature reviews demonstrate a positive correlation between tonsillectomy and MS and between tonsillectomy and CD.
* Studies say more research is needed.

"Which ref says there is a "lack of literature reviews"?"
:The only secondary sources I have found so far are about CD and MS. Therefore it seems likely that there are no other secondary sources between tonsillectomy and the incidence of disease (published in a language that I understand), but the whole problem of course is that it is impossible to know for sure that something does not exist. Maybe we could explicitly say that the studies on biomarkers did not look at the incidence of disease.
"Are those correlations significant? Or simple small changes in rare diseases?"

This article that you cited [https://www.sciencedirect.com/science/article/abs/pii/S0165587615002360?via%3Dihub] says that verbatim.

These articles do not say what you're quoting and do not support the text you're trying to include. I see no mention in these article saying "Those studies, however, do not consider the incidence of disease." when I search their text. That sounds like your analysis of those articles.

:Additionally, this article [https://www.ncbi.nlm.nih.gov/pubmed/26678358] does indeed conclude that it found an association between tonsillectomy and a higher risk for Crohn's disease (it also found a protective effect on ulcerative colitis which you didn't mention). It also concludes "Further prospective studies are required to confirm the validity of these observations.", which strongly suggests it is not definitive (as one meta-analysis shouldn't be anyway). In contrast, this meta-analysis [https://www.ncbi.nlm.nih.gov/pubmed/26946482] did not find any such association. I wouldn't phrase it as some studies have found X. I think the way it was stated before (that whether any such association is present is currently unclear) was fine since results are mixed. 

:As for multiple sclerosis, the study you cite does say exactly what you said, but it appears to be the only such meta-analysis. It's also from observational data meaning it has many limitations (and it comes from a low-impact journal). Lastly, the same conclusion from that analysis says this: "Despite this significant finding, this in no way suggests or demonstrates causality, in that epidemiological studies can only provide etiological clues at best. More rigorous prospective studies, with high statistical power, are needed to prove an effect." So, I wouldn't phrase it the way you did above since I think a lot of readers would misinterpret that to mean tonsillectomy is definitively linked to a significantly (clinically speaking, that is) higher risk of multiple sclerosis. Based on the available evidence, this meta-analysis suggests that but given the limitations I don't think we can say that with great confidence at this time.

It claims to be the first study to look at the long-term risk (2018, vs the one I quoted above on the lack of correlation with crohn's which was 2019). They did not control for familial disease trends.

I think [https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0183214 this article] describes very well the controversy and uncertainty regarding the impact of tonsillectomy on the immune system:

''Although the discussions on the role and importance of tonsils for the immune response are controversial, a significant contribution of the tonsil palatina to immunity is supported by a number of studies, which described an association between tonsillectomy and increased susceptibility to infections. (...) In contrast to the previous reports a number of studies and meta-analysis did not observe significant immune alterations following tonsillectomy. (...) Despite all these appreciations, there is an ongoing debate as to the net benefit of tonsils as a functional lymphoid organ and their contribution to infection control in humans. This controversy is not least fostered by the paucity of solid experimental data on the immunological status of tonsillar immune cells in the context of the various inflammatory conditions that can afflict the tonsil.''

==Discussion on incentives for removal==
I think we should consider merging the financial incentives and parental pressure sections into the "reasons" area.  The stated "reason" for removal is [surgeon/health facility] "financial incentive" but the references don't support it. Ref#48, is a single study by a single author.  Ref#49 is 51 years old, and a lot has changed, but even then i can't even see a summary anywhere (plus it was a preliminary report). Ref #51 is Obama's quote where he mentions T&A as an example of FFS influencing decisions.   

A proper study would compare the level of reimbursement (e.g the fee paid) and T&A rate with contemporary indications for removal.  Comparing FFS vs salary, is a separate issue, as is 1960's indications vs modern ones. Even though the parental pressure ref#52 is a commentary, it's actually a good summary of the entire situation imo.  Also, wrt financial incentives, no mention is made of populations that can't afford private pay treatment.  Do they suffer more?  Both sides of the coin should be examined if we create an entire section on it. [[User:Ian Furst|Ian Furst]] ([[User talk:Ian Furst|talk]]) 13:53, 26 June 2019 (UTC)
:{{ping|Ian Furst}}Thanks. I will take a look at it this weekend and edit the article if necessary. But for now I can say this: 1) No child has ever asked to be knocked out and have two or three of its organs removed. 2) It is abundantly clear that even in severe cases the benefits of tonsillectomy are modest at best. 3) There are strong indications that tonsillectomy increases the incidence of a broad range of diseases. Yet every year, hundreds of thousands, if not millions, of young children worldwide have their tonsils taken out. This can only be because surgeons get paid for doing this procedure or because of their biased views and / or parents want to have this procedure done because of psychological reasons. Furthermore, I believe the argument of "undertreatment" is simply not credible. Although tonsillitis (especially if it is chronic or recurrent) may be very disturbing, it is not life threatening, nor is it likely to cause any serious any long term health risks. Tonsillectomy rates vary considerably between similar countries, yet I have not heard of large numbers of children experiencing serious health issues because their tonsils have not been taken out in countries where tonsillectomy rates are low.

== Parental pressure ==

Several references mention parental pressure, but none quoted so far address the specific effect.  I think we have two separate issues; (1) does parental pressure make it more likely for the tonsils to come out, and (2) does it increase the chance of referral to ENT.  Poor references keep getting inserted, last one was a ?dissertation in Dutch.  Another was a commentary.  Will look through guidelines for a better reference.  I suspect it's addressed somewhere in a consensus paper or something [[User:Ian Furst|Ian Furst]] ([[User talk:Ian Furst|talk]]) 18:51, 3 July 2019 (UTC)
:Regarding question #1: In [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1974118/ this article] from 1957 (a long time ago, I admit) the author says that of the 40 children who had their tonsils removed, 6 (15%) had the procedure done because of parental pressure. It is very likely that this has also happened elsewhere. About question #2: According to [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1947283/?page=2 this article] from 1972 (also a long time ago) which I find very interesting and credible, "Too often physicians scheduled [adenotonsillectomies] out of habit or in response to parental pressure". I would not say that the references I have found are "poor", although I admit that some are better than others. The Dutch source from 2009 for example, is not bad at all in my opinion. But I'm sure we can find more and better sources. When I enter "tonsillectomy" combined with "parental pressure" in Google, I get around 2.470 results, which probably excludes many other relevant pages (including those in other languages than English) that cannot be found using those exact terms.

Plus, it's a bookkeeping excercise and doesn't directly address the parental pressure issue.  Imo, a parent is likely to read the lead of wikipedia, but caregivers (both formal and informal) are going to read the details.  If we give them contemporary, evidence-based facts it has the potential to do the most good.  There are great references out there, like the consensus statement that's quoted everywhere (including the dutch economics paper).

:::{{ping|Ian Furst}} I find it astonishing that so many parents opt for a medical procedure that is so ineffective and so potentially harmful, especially now we live in the information age. Tonsillectomy is an elective procedure, so the most important reason it happens is because the parents want it. By far, most children simply outgrow tonsil related diseases and those diseases are unlikely to be fatal, contrary to, for example, an appendicitis. Furthermore, I have found dozens and dozens of studies that prove that tonsillectomy does harm the immune system profoundly (increased risk of cancer, allergies, diseases in the upper respiratory tract, heart attack, autoimmune diseases and inflammatory diseases for example). And then there also the risks of general anaesthesia, such as cognitive disorders later in life. The benefits of tonsillectomy are in the vast majority of cases minor and temporary, whereas the drawbacks are forever and potentially profound as the procedure involves the permanent removal of the entire first line of defence of the immune system.

:::::{{ping|Ian Furst}} You have deleted the parental pressure section again. I just checked the [https://en.wikipedia.org/wiki/Wikipedia:Identifying_reliable_sources_(medicine) the page about MEDRS] but could not find anything there that convinces me that a PhD dissertation is not MEDRS. Could you please let me know why a PhD dissertation is not MEDRS? Or maybe even better, could you write something about parental pressure yourself? [[User:Zesd|Zesd]] ([[User talk:Zesd|talk]]) 13:55, 10 July 2019 (UTC)
::::::The source quotes two primary studies, both of which were small surveys of GP's in England (the doctoral candidate discusses the limitations of the studies in the dissertation). Neither a PhD submission, or the original science it quotes, is considered a generally accepted fact.  Also, we've all agreed not to use primary research (a PhD dissertation is, by definition, original science). The fact you stated was "According to several studies, parental pressure sometimes plays a role in the decision-making of general practitioners and ENT consultants." under tonsillectomy rates. This is misleading imo because the source states that parental pressure influenced referral rates, not tonsillectomy rates.  Between the misleading statement, and the poor reference I removed it.  I can't find a contemporary MEDRS that states the surgeons tonsillectomy rates are influence by parental pressure.

::::::: {{ping|Ian Furst}} Even if we cannot find good quality sources that confirm that parental pressure increases tonsillectomy rates, we could still say something about parental pressure. For example, we could say that parental pressure influences referral rates, but it is not clear whether those higher referral rates subsequently result in higher surgery rates (although it is extremely likely, especially if the surgeon is paid fee-for-service reimbursements). The whole parental pressure thing is an interesting psychological phenomenon anyway, so why not give it a bit of attention.  [[User:Zesd|Zesd]] ([[User talk:Zesd|talk]]) 21:25, 10 July 2019 (UTC)

== Secondary sources ==
Can anyone explain to me why [http://www.aarc.org/nn19-tonsillectomy-long-term-effects/ this article] does not qualify as a secondary source? It is an advice from the American Association for Respiratory Care, so I would say it can be considered a position statement by a well respected medical organization. [[User:Zesd|Zesd]] ([[User talk:Zesd|talk]]) 19:43, 11 July 2019 (UTC)
:Sure; [[WP:MEDRS]] stipulates that facts should be backed by consensus statements or position statements when coming from organizations.  This is an anonymously authored web page with ?3 linked papers (one of which is extensively discussed in the the article already).  I think you're claiming that it would qualify under [https://en.wikipedia.org/wiki/Wikipedia:Identifying_reliable_sources_(medicine)#Medical_and_scientific_organizations this heading], but the AARC is not a major international organization, and the webpage was not some massive, well referenced consensus.  Compare to something like [https://www.who.int/immunization/diseases/dengue/en/ this] on dengue fever which is heavily referenced, and from the WHO.  I'd also add that the statement of fact you claimed, "... several studies that demonstrate an association between tonsillectomy and certain diseases..." is vague, and arguably falls under the RfC the community agreed to previously.

== Obstructive Sleep Disordered Breathing ==

Obstructive Sleep Disordered Breathing is an indication for adenotonsillectomy in children in the USA, and the majority of procedures in this country are performed for this reason.

The only place Obstructive Sleep Disordered Breathing is mentioned in this article is in the 2018 UK study reviewing indications for the procedure, indicating this is a frequent and non-indicated reason for the procedure in the UK.  I practice in the USA and don't know if this is accurate or not.  

The Section "Obstructive Sleep Apnea" under "Medical Uses" states that OSA is an indication for tonsillectomy without referencing any specific age group and then references the 2019 update to AAO-HNS Clinical Practice Guideline for Tonsillectomy *in Children*.  This paragraph goes on to state that "The procedure is recommended for those who have OSA that has been verified by a sleep study.[1]"  This is a distortion of this guideline, which states first that OSDB is a clinical diagnosis and an indication for adenotonsillectomy, and further that a sleep study may be indicated in specific patient populations, such as those without apparent obstructive anatomy.  

I am going to make an edit to the paragraph to clarify this but would welcome others' thoughts.  <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Apcpa|Apcpa]] ([[User talk:Apcpa#top|talk]] • [[Special:Contributions/Apcpa|contribs]]) 18:11, 15 July 2019 (UTC)</small> <!--Autosigned by SineBot-->
:{{Ping|Apcpa}} Because of the historic over prescription of tonsillectomy, and current wide variation between regional rates there is a lot of debate within this article.  As such, we look for very strong evidence to include in the indications sections.  Either consensus statement, meta-analysis or cochrane study to support each statement of fact. I'll take a look at the specific guideline too.  Is there a consensus statement about diagnostic criteria for which OSDB patients receive T&A?

== Questions that need to be answered in the article ==

In my opinion, the article is missing some crucial information. I would like to see the following three questions answered: 

* If tonsillectomy is effective in treating OSAS and recurrent / chronic tonsillitis, is generally safe and does not harm the immune system in any way, then why have tonsillectomy rates decreased so drastically over the past decades in most countries?
* If the tonsils are important and serve as the first line of defence in the immune system, then why does tonsillectomy not compromise the immune system?
* What is the role of parental pressure in the decision process whether the tonsils need to be taken out?

Can anyone give an answer to each of these three questions, backed up by secondary sources? I would be very grateful.

This is from a commentary on a primary source not a review

"In reaction to a 2018 study from Denmark that demonstrated a positive association between childhood tonsillectomy and around twenty diseases later in life, the [[American Academy of Otolaryngology–Head and Neck Surgery]] commented that this study may be biased because of unmeasured [[confounding variables]], [[reverse causation]], [[selection bias]] and [[Measurement Bias|measurement bias]].<ref name=":6">{{Cite web|url=https://bulletin.entnet.org/article/tonsils-adenoids-and-long-term-immune-function/|title=Tonsils, adenoids, and long term immune function|website=bulletin.entnet.org|language=en-US|access-date=2019-10-03}}</ref> However, it also said:<blockquote>[It] is certainly a provocative and well executed study that may add some nuance to how we counsel parents when this all-too-common question comes up.<ref name=":6" /></blockquote>" [[User:Doc James|<span style="color:#0000f1">'''Doc James'''</span>]] ([[User talk:Doc James|talk]] · [[Special:Contributions/Doc James|contribs]] · [[Special:EmailUser/Doc James|email]]) 00:42, 4 October 2019 (UTC)

==Range of deaths==

Per source

"Current US reported mortality rates for tonsillectomy are 1 per 2360 and 1 per 18,000 in inpatient and ambulatory settings, respectively,46,47 while the province of Ontario, Canada, reported a combined inpatient/outpatient setting mortality rate of 1 per 56,000 for the years 2002 to 2013. A prospective audit reported only 1 postoperative death after 33,921 procedures in England and Northern Ireland."

So the death rate in the US is not actually 1 in 2360. [[User:Doc James|<span style="color:#0000f1">'''Doc James'''</span>]] ([[User talk:Doc James|talk]] · [[Special:Contributions/Doc James|contribs]] · [[Special:EmailUser/Doc James|email]]) 01:24, 11 December 2019 (UTC)

==2019 Consenus statement and the section on sore throat==
I'd like to proposed that we blow-up most of the section on sore throat (which has been melded from multiple sources) and harmonize it with Statements 2 and 3 from the consensus conferences.   
"Clinicians may recommend tonsillectomy for recurrent throat infection with a frequency of at least 7 episodes in the past year, at least 5 episodes per year for 2 years, or at least 3 episodes per year for 3 years with documentation in the medical record for each episode of sore throat and ≥1 of the following: temperature >38.3°C (101°F), cervical adenopathy, tonsillar exudate, or positive test for group A beta-hemolytic streptococcus. Optionbased on systematic reviews of randomized controlled trials, with a balance between benefit and harm." and the other statement already blockquoted.

:We could remove the 2011 guideline (we now have a more up to date guideline from 2019) and "The panel also recommended..." part (most of it is not about sore throat). For the rest it is better to leave it as it is in my opinion. [[User:Zesd|Zesd]] ([[User talk:Zesd|talk]]) 19:08, 3 January 2020 (UTC)

== section "tonsillectomy rates" ==

has this text: "This means there is a seven-fold difference between the region with the highest tonsillectomy rate and the region with the lowest one.[13] In 2006, English Chief Medical Officer Liam Donaldson revealed that unnecessary tonsillectomies and unnecessary hysterectomies combined cost the British National Health Service 21 million pounds a year.[44]"

-i dont see the reason the "sevenfold" difference between regions needs to be italicized as it is in the current article text, since the section title is about the rates, and not the SIGNIFICANCE attributed to those rates. an emphasis would be reasonable if the section was to make an argument to change the rates of tonsillectomy, but at the current title it is supposed to remain neutral and just list the numbers without emphasizing on what is 7 times higher. it is actually degrading to read a text that supposes that i cant see for myself that 7000 per 100 000 (or something similar) is SEVENFOLD higher than 1000 per 100 000. 
:Ok. Changed it.[[User:Zesd|Zesd]] ([[User talk:Zesd|talk]]) 18:26, 25 February 2020 (UTC)

-on the other hand i would welcome a change of title for the section because as it reads now, section 5, 5.1, and 5.2 are not really about the rates and its subsections but rather on the same logical level, so perhaps it would be better to rename section 5 to something like "controversy about recommendation" and put the text from section 5, 5.1 and 5.2 under subsections 5.1, 5.2 and 5.3 . this citation: "English Chief Medical Officer Liam Donaldson revealed that unnecessary tonsillectomies " shows that the intent of the text is criticism of the (frequent application of the) procedure and not just collecting data on the rates of procedure in different regions. so it would be more honest to title the section accordingly.
:This has been edited many times, so for now I would like to keep it as it is.[[User:Zesd|Zesd]] ([[User talk:Zesd|talk]]) 18:26, 25 February 2020 (UTC)

-at the same time this: "English Chief Medical Officer Liam Donaldson revealed that unnecessary tonsillectomies and unnecessary hysterectomies combined cost" citation raises questions:

-- why the opinion of the chief med officer about financing is taken as a fact and given weight in the article that is not about the financing side of this procedure. also the talk about COMBINED costs shows that the whole Med Chief opinion cited is more of a rhetorical acomplishment than a logical inquiry of reasoning - so perhaps it would be best to find a reliable source that is not talking about pears and apples when your article needs to focus on apples.
:I agree with you that the source you are referring to is far from perfect because indeed it 1) focuses on costs rather than numbers of surgeries and 2) it simply adds up tonsillectomies and hysterectomies (which are completely unrelated to each other). However, it is still a strong indication that the number of tonsillectomies performed in the UK is way too high, which is especially interesting because it is a country where tonsillectomy rates are relatively low. Furthermore, by mentioning hysterectomies, it is made clear that the problem of overtreatment extends beyond tonsillectomies.[[User:Zesd|Zesd]] ([[User talk:Zesd|talk]]) 18:26, 25 February 2020 (UTC)
