Treatment of midline cleft of the mandible-A 2-stage approach.

Midline clefts of the lower lip and mandible are rare congenital anomalies. They may present as complete or incomplete in nature along with associated bifid tongue and ankyloglossia. Some may present with cleft of lower lip, cleft of mandible, fissured tongue, absent hyoid bone, cleft of manubrium sterni, or an extremely rare anomaly known as Tessier cleft no. 30. We present this unique case of midline cleft of the lower lip (incomplete) and mandible (complete) with initial soft-tissue surgery for the lower lip. The hard-tissue surgery for this case is deferred at a later date, and the reasons are discussed.
