Bilateral congenital pits of the upper lip.

Congenital sinuses, fistulas, dimples, or pits of the lips are uncommon congenital malformations. In the upper lip they are extremely rare, and only one third of them are placed laterally. The authors present a patient with bilaterally placed upper lip pits associated with speech disorders, a short and everted upper lip with an orbicularis muscle defect in the midline, slight hypertelorism, and low-set ears. Orbicularis muscle repair and tubercle augmentation were performed. No further treatment was administered to the upper lip pits because of lack of symptoms. This is the third bilateral case of the sinus or pit of the upper lip reported in the literature.
