Infraorbital groove
Template:Short description Script error: No such module "Distinguish". Script error: No such module "Infobox".Template:Template otherTemplate:Main otherScript error: No such module "Check for unknown parameters". The infraorbital groove (or sulcus) is located in the middle of the posterior part of the orbital surface of the maxilla. Its function is to act as the passage of the infraorbital artery, the infraorbital vein, and the infraorbital nerve.
Structure
The infraorbital groove begins at the middle of the posterior border of the maxilla (with which it is continuous).[1] This is near the upper edge of the infratemporal surface of the maxilla. It passes forward, and ends in a canal which subdivides into two branches.
The infraorbital groove has an average length of 16.7 mm, with a small amount of variation between people.[1] It is similar in men and women.[1]
Function
The infraorbital groove creates space that allows for passage of the infraorbital artery, the infraorbital vein, and the infraorbital nerve.
Clinical significance
The infraorbital groove is an important surgical landmark for local anaesthesia of the infraorbital nerve.[1]
