Treatment of bilateral macrostomia [lateral lip cleft]: case report

Macrostomia as a rare facial deformity is classified among facial clefts. It originates from failure in union of maxillary and mandibular prominences of first brachial arch during 7[th] embryonic week. We report a case of bilateral macrostomia [bilateral lip cleft] in a female newborn as a sole entity without other skeletal and facial deformities. The cleft was repaired by a simple linear triangular flap using extra oral landmarks to locate lip commissures. Patient was followed through a six-month period. Acceptable results were gained in mouth appearance as well functional aspects. Commissural repair through a linear flap can result in minimal visible scar with satisfying results in both esthetics and functional aspects
