[Bilateral congenital macrostomia].

INTRODUCTION: Congenital macrostomia, a transverse facial cleft, is a rare deformity of the mouth, which can occur alone or in association with other deformities. We report a case of congenital bilateral macrostomia. We discuss the difficulties of plastic surgery in this pathology. OBSERVATION: Congenital macrostomia in a one-year-old girl compromised feeding. The patient presented an isolated bilateral transverse facial cleft. Surgery associated a suture of the orbicularis oris muscle and a cutaneous W plasty. At twelve months, follow-up has been uneventful. DISCUSSION: Congenital macrostomia is most commonly associated with others anomalies. Many procedures are described regarding surgical correction of macrostomia. Reconstruction of the integrity of the oral sphincter associated with W plasty usually gives the best results.
