Prenatal Ultrasonic Features of Median Cleft of the Lower Lip and Mandible With Ankyloglossia: A Rare Case Report and Literature Review

Median cleft of the lower lip, midline mandibular cleft, or Tessier 30 cleft is a rare anomaly. We present a case involving the prenatal diagnosis of a median cleft of the lip and mandible associated with ankyloglossia, directly attached to the gingiva and lower lip. Postnatally, the condition was managed with a combined surgical approach of split labiaplasty and tongue-tie plasty in the stomatology department. The outcome was favorable following the transverse incision of the lower portion of the tongue-tie. The sonographer must carefully examine the craniofacial section to minimize the risk of missed diagnosis.
