Despite the trend in current surgical practice in the treatment on melanoma to produce smaller excisional defects, any technique which can introduce a surgical closure that does not require split skin grafting must be of benefit. This paper introduces and illustrates a range of island flap techniques that employ no skin grafting for the treatment of malignant melanoma defects. The new cutaneous island flap described, termed the Bezier or the French Curve, employs a double V-Y appositional closure method, thus giving a more refined reconstructive result that fits into the line of the body curves aesthetically. The design of the Bezier flap is almost identical in size and shape to the excisional defect, with a facial or muscular base for vascular support. Appropriate guidelines that determine the design and application of this island flap technique are listed. They are illustrated both diagrammatically and clinically. Other flaps illustrated include fasciocutaneous island flaps and myocutaneous island flaps that use a single V-Y flap appositional closure technique. All these flaps were designed with special reference to the dermatomes, which act as an aid memoire upon which the flaps are marked. |
