Skin grafts and local flaps

Expedited healing of skin wounds is essential regardless of surgical specialty. Any skin deficiency will thwart this basic intent, and an alternative must be sought. The autogenous skin graft or local flap has long had a major role in satisfying this objective. Various forms of autogenous skin grafts are to be differentiated from local flaps, primarily on the basis of vascularization. The indications for either, their surgical anatomy, harvest techniques, and limitations, including pitfalls, need to be outlined. Skin grafts are the simplest means to restore skin integrity. If skin grafts are contraindicated, a flap may be essential. For this purpose, the "top ten" local "workhorse" flaps are briefly described in this article. Accompanying videos further elaborate the requisite surgical anatomy and harvest techniques. As a problem-solving specialty, it is incumbent upon us to first prevent, then be able to provide rapid, efficient, and efficacious healing of, any surgical wound, iatrogenic or otherwise. Skin grafts and local flaps are fundamental elements for achieving this goal when healing by primary or secondary intent is not possible. Whether one is a "reconstructive" or "aesthetic" plastic surgeon, knowledge of these basic tenets will ensure maintenance of competency.     

New microsurgical breast reconstruction using free paraumbilical perforator adiposal flaps

Pedicled transverse rectus abdominis musculocutaneous (TRAM) flaps have generally been used for bilateral breast losses. The major disadvantages of this method are the total or partial loss of the rectus abdominis muscles and various resulting postoperative complications, such as abdominal bulging and lumbar pain. With the recent development of perforator flaps and supermicrosurgery with anastomosis of 0.5-mm caliber vessels, these serious complications can be overcome with a paraumbilical perforator adiposal flap, without sacrificing the rectus abdominis muscle. The breasts of a 57-year-old woman who had undergone a bilateral subcutaneous mastectomy, including silicone prostheses, were repaired simultaneously with this new method using free paraumbilical perforator adiposal flaps. This new method of breast augmentation with a vascularized adiposal flap and without any muscle component is minimally invasive; its advantages are the preservation of the rectus abdominis muscles and the short time elevation for the adiposal flap.     

Correction of inverted nipple with periductal fibrous flaps.

I devised a method to correct the inverted nipple considering the preservation of the lactiferous ducts, sensory fibers to the nipple, and the contracting function of the areolar muscle. Excision of the excess skin at the base of the nipple was done in three diamonds fashion, and they were located at 2, 6, and 10 o'clock positions not to jeopardize the sensory fibers to the nipple. To release the fastened nipple, the periductal fibrous tissue was thoroughly dissected and made into three flaps pedicled inferiorly. These three flaps were sutured to the dermis of the periareolar skin to pull up the nipple base by means of traction in three directions. The purse-string suture, the dermal stitch on the shorter diagonals of the diamond-shaped defects, anchors the skin-muscle bridges caught at the base of the ductal column, makes the nipple base narrower, obtains stable anchoring, helps the areolar muscle contraction to resume, and prevents the recurrence of the inversion. The use of the periductal tissue as flaps to bring in areolar skin for easier anchoring and for more prominent eversion of the nipple has not been described in the literature.     

Composite reconstruction for chest wall and scalp using multiple ribs-latissimus dorsi osteomyocutaneous flaps as pedicled and free flaps

A composite flap is presented based on the latissimus dorsi myocutaneous unit together with the underlying ninth to eleventh ribs. Three patients are presented. In two, a full-thickness chest-wall defect was present. In one, a full-thickness scalp and cranial defect was present. Use of the composite osteomyocutaneous latissimus dorsi free flap as a pedicled flap in two patients and as a free flap in one patient resulted in successful definitive reconstruction in all with no complications. This procedure necessitates no transplantation of soft tissue prior to bone grafting to maintain local vascularity, so the simultaneous one-stage reconstruction of an osseous-soft-tissue defect becomes possible easily.     

Autologous fat graft in nipple reconstruction

Reconstruction of the nipple is the penultimate step in breast reconstruction after mastectomy. A number of reconstructive techniques have been described for nipple reconstruction including skin grafts, composite grafts, and various local flaps. The authors' preferred reconstructive technique is the local C-V or modified star flap. This flap produces an excellent reconstruction, but it is dependent on underlying subcutaneous fat to provide bulk to the reconstructed nipple. In most instances, the subcutaneous tissue is adequate. However, under certain circumstances, the subcutaneous fat may be insufficient to produce a nipple of adequate projection. Two cases of bilateral nipple reconstruction after soft-tissue expansion and implant placement and subsequent nipple reconstruction with local flaps provided inadequate nipple projection. These instances, as well as a retrospective review of reconstructed nipples after mound restoration using a variety of techniques, led the authors to conclude that a more predictable alternative to sustain nipple projection was necessary. The authors identified two broad categories of breast reconstruction patients in whom this new technique would be beneficial. In the first category of patients, breast mounds are reconstructed with tissue expansion and implant insertion, and in the second category, breast mounds are reconstructed by any technique in which the nipple reconstruction subsequently flattens. This article describes the indications, techniques, and experience in 13 patients treated over a 10-month period with fat grafting for nipple reconstruction.
