Abstract
Median cleft of the lower lip and mandible is extremely rare. In our cou ntry, only nine cases have been reported so far in the literature. In this paper we present a three-month-old girl with a median cleft of the lower lip and mandible. Neither family history nor associated malformations of other portions of the patient was noted. At the age of four months reconstruction of the cleft lip with z-plasty and of the ankyloglossia was performed. But no surgical intervention was made on the cleft of mandibular bone. The reasons why the surgery of the mandibular cleft is better postponed until her second decade of age is also discussed.
