Agnathia (also termed hypognathous)[1] is the absence of a portion or the entirety of one or both jaws.[1][3] It is a very rare condition.[1] External, middle, and inner ear abnormalities, as well as temporal bone, parotid gland, masticatory muscles, and facial neural abnormalities, frequently coexist with Agnathia. Agnathia is seen in agnathia-holoprosencephaly, otocephaly, and Ivemark syndrome.[2]
