[Median cleft of the lower lip. Apropos of a case].

The authors report a case of median cleft of the lower lip and mandible. This is rare malformation (60 cases published in the literature) with anomalies of the tongue and sometimes midline cervical cord. Cleft of the lower lip is repaired early between one and six months, but the correction of mandibular defect by bone graft will be done at the age of ten years. In this way the authors hope to preserve mandibular and teeth growth.
