Mandibular Hypoplasia

A small lower jaw is known as mandibular hypoplasia and it can be isolated or part of a syndrome (along with other deformities). One or both sides of the jaw can be involved and treatment is aimed at lengthening the part of the jaw that is affected.  This can be accomplished surgically using either bone grafts or mandibular distraction.  Treatment is aimed at improving the facial aesthetics as well as the functional bite (occlusion).
