<unk>  is a surgical subspecialty that deals with congenital and acquired deformities of the head, skull, face, neck, jaws and associated structures. Although<unk>  treatment often involves manipulation of bone,<unk>  is not tissue-specific;<unk>  surgeons deal with bone, skin, nerve, muscle, teeth, and other related anatomy. Defects typically treated by<unk>  surgeons include craniosynostosis (isolated and syndromic), rare<unk>  clefts, acute and chronic sequelae of facial fractures, cleft lip and palate, micrognathia, Treacher Collins Syndrome, Apert's Syndrome, Crouzon's Syndrome,<unk>  microsomia, microtia and other congenital ear anomalies, and many others.Training in<unk>  requires completion of a<unk>  fellowship.

Those who have completed residency in oral and maxillofacial<unk>  may be either single degree or dual-degree surgeons with no differences. There is no specific board for<unk> .
