Question: what is alveolar mandibular hypoplasia?
Answer: ENT surgery. Maxillary hypoplasia, or maxillary deficiency, is an underdevelopment of the bones of the upper jaw, which produces midfacial retrusion and creates the illusion of protuberance (jutting forward) of the lower jaw. It is associated with Crouzon syndrome, Angelman syndrome, as well as fetal alcohol syndrome.
