Lip reconstruction of comparatively large defect including the commissure using remaining lip tissue: A modification of reconstructed method

We present two reconstructed cases after malignant skin tumor of comparativ ely large defects of lip including the commissure using remaining lip tissu e alone. After resecting a tumor including wedge-shaped full-thickness lip tissue, a full thickness oblique incision is made at the site 5 mm distant from the contralateral commissure. The rhomboid-shaped lower lip flap is cr eated, transposed to the defect, and sutured with the defect margin, includ ing the upper lip, to reconstruct the commissure. The cross Lip flap is cre ated at the contralateral side of the lower lip, 5 mm from the commissure, and the defect is closed with the crosslip flap. Although our method is app licable only to selected cases, we believe that it is useful in terms of ma intaining symmetry of the lip and function of the commissure in the reconst ruction of comparatively large defects including the commissure.
