Agnathia (also termed hypognathous)[1] is the absence of a portion or the entirety of one or both jaws.
[1] External, middle, and inner ear abnormalities, as well as temporal bone, parotid gland, masticatory muscles, and facial neural abnormalities, frequently coexist with Agnathia.
[2] X-rays or CT scans of the mandible and temporomandibular joint showcase the extent of underdevelopment and differentiate Agnathia from other disorders that cause similar facial abnormalities but do not involve substantial structural loss.
[2] Agnathia treatment consists of rapid reconstruction using autogenous bone grafting to stop the further development of facial deformity.
