congenital double lip: an experience with 5 cases and a proposed new method for surgical correction

congenital double lip anomaly is an infrequent developmental abnormality affecting the lips, more commonly the upper lip. 5 cases of double lip are being reported for the first time from iran and all confined to the upper lip. a new surgical excision is being introduced which is called transverse cupid bow-like elliptical incision. the previous traditional method was a simple elliptical excision. the new method gives the cupid’s bow a more natural apperance and keeps the normal shape of the upper lip.surgical excision with transverse cupid bow-like elliptical excision in undertaken with regional nerve block anesthesia.it was interesting to observe that in the upper lip, the buccal portion of the double lip appeared on either side with a midline constriction. surgical excision with the new method under regional nerve block anesthesia provides good result. the embryology and clinical appearances are discussed with a review of the literature.congenital doble-lip anomaly is rare, and 5 cases are beint reported. all the patients were males, and there was no hereditary history, relation of the parents or any obvious acquired etiologic factor for the development ot this molformation.
