Reconstruction of the upper lip, columella and premaxilla with an extended Abbé flap: report of a case.

The resection of malignant tumours affecting the upper lip, columella, premaxilla and/or caudal septum requires reconstructive surgery, which does not always produce satisfactory results-either aesthetic or functional. We have designed a modification of the Abbé flap consisting of the extension of the distal portion of the latter over the chin, and the inclusion of a fragment of rib cartilage in this portion of the flap. The columella is reconstructed in this way, and the cartilage serves to buttress the pyramid tip and prevent its collapse. A case is reported, with good aesthetic and functional results. Other surgical procedures are discussed, analysing their advantages and inconveniences.
