Template:Short description Microgenia is the medical term for an unusually small or deformed chin.[1]
The contrasting condition, an enlarged chin, is called "macrogenia".[2][3][4]
There are seven different chin deformities:
- Class I: Macrogenia (chin excess)
- Class II: Microgenia (chin deficiency)
- Class III: Combined excesses and deficiencies
- Class IV: Assymmetric deformity
- Class V: Witch's chin
- Class VI: Pseudomacrogenia
- Class VII: Pseudoretrogenia
Class II microgenia is the most commonly encountered chin deformity, followed by class II macrogenia.[5]
Causes
Can occur in anyone, but is often a sign of Down syndrome.[6][7][8]
