Abstract
Orofacial clefts are common congenital malformations. Tessier's classification system is the most widely used; it consists of 30 variants including median mandibular clefts (Tessier's cleft No. 30). They can be isolated or associated with cleft of the lower lip, tongue or more rarely, of the sternum. They are very rare, less than 70 cases (all types taken together) have been reported in the literature. We here report an exceptional case of mandibular and sternal cleft with literature review.
