Biwinged excision for closure of rounded defect.
A new technique for closure of rounded defects is described. The biwinged procedure consists of excising two equal triangles on either side of the defect, one above and one below the dissecting line. Closure is in the form of a step. It can be made to parallel in part a wrinkle or contour line, such as a nasolabial fold, a temporal region above and beside the eyebrow, an area over the lower border of the mandible, or on the dorsum of the hand. A mathematical comparison of the amount of healthy tissue in the biwinged excision and in six other procedures is presented.
