Abbe Flap Reconstruction of the Upper Lip.

Abstract

Reconstruction of substantial-sized upper lip defects may require an Abbe flap reconstruction to avoid excessive tightness and deformity. The design of the Abbe or lip switch flap harvested from the lower lip is important for a satisfactory aesthetic and functional result. Harvest of the flap is performed to enable a definitive inset into the defect. The video that accompanies this article depicts rotation of an Abbe flap into a philtral defect created by basal cell carcinoma excision.
