Congenital Type III Lip Sinus with Palatine Bone Cleft.

Congenital lip sinuses are rare developmental anomalies that usually occur in isolation, except for lower lip sinuses, which may be associated with cleft palate. We present a rare case of a congenital upper lip sinus associated with palatine bone cleft, unilateral choanal atresia, and epibulbar dermoid in a neonate.
