An apparent duplication of the mouth in a patient with midline dysraphism and a teratoid polyp: A 15-year postsurgical follow-up.

True median cleft of the upper and lower lip occurs very rarely. Complete or partial facial duplication is an extremely rare malformation. Approximately 26 cases have been reported since 1900, spanning a wide spectrum of clinical severity. Most cases appear to share a number of features, including cleft palate, duplication of the tongue, orbital hypertelorism and macrostomia. An unusual patient with midline clefts of the upper and lower lips with an apparent duplication of the mouth and a teratoid polyp, with fusion of the maxilla and mandible, is reported. The early management and surgical intervention is discussed. Furthermore, postoperative outcomes are reviewed as part of a 15-year postsurgical follow-up.
