simple explanation



The jaw can be missing deformed or incompletely developed at birth.


Birth defects of the jaw include


Micrognathia


Agnathia


Maxillary hypoplasia


Micrognathia is a small lower jaw (mandible). Pierre Robin sequence and Treacher Collins syndrome which are disorders characterized by several defects in the head and face are associated with a small lower jaw. If the lower jaw is too small the infant may have difficulty eating or breathing. Surgery to extend the jaw may correct or diminish the problem.


Agnathia a condition in which a part of or the entire lower jaw is missing is a severe malformation. Often the infant also has abnormalities of the ears temporal bone saliva glands the muscles used in chewing and facial nerve. Treatment of agnathia consists of reconstructive surgery with bone grafts and other tissue grafts to improve the appearance and function of the jaw.


Maxillary hypoplasia is underdevelopment of the upper jaw (maxilla). It causes a flat mid-face which makes the lower jaw appear to stick out. Treatment of maxillary hypoplasia involves surgery to reposition the upper jaw and align it with the lower jaw.


Doctors diagnose all of these defects by assessing the degree of jaw underdevelopment with x-rays and computed tomography (CT) of the face.
