Mucous-flap method for cleft-lip revision using transverse everted full-length lower-lip flap.

Abstract

In patients who had undergone the first surgery for cleft lip and in whom the volume of tissue was smaller for the upper lip than for the lower lip, transfer of tissue from the lower lip using a full-length mucous flap allowed the tissue volume of the upper lip to be increased and external appearance of the lips to be improved. The subjects of this study were 6 patients who underwent this surgery between February and September 2001 and were followed for up to 3 years postoperatively. This surgery can be performed under topical anesthesia, without necessitating restriction on mouth opening and oral ingestion. Furthermore, it allows easy adjustment of the tissue volume in both upper and lower lips. This operative procedure is recommended for cases of cleft lip where surgical treatment has been performed before and the tissue volume is smaller in the upper prolabium than in the vermilion.
