Abstract
Large upper lip defects that include the surrounding aesthetic subunits of the midface are difficult to reconstruct. Abbé flaps have been a popular method of dealing with small upper lip defects but, as classically described, they are insufficient for larger defects.

Extended Abbé flaps were then designed and used in combined upper lip and midfacial reconstruction. Three cases and guidelines for the use of the extended Abbé flap are presented.
