Free-flap reconstruction of the scalp: donor selection and outcome

Wide, complex defects of the scalp caused by various insults always represent reconstructive challenges for surgeons. Our study group consisted of 18 patients (14 males and 4 females) with a mean age of 40.2 years. Nineteen free-tissue transfers were used to reconstruct the scalp defects. The selected cases included 8 latissimus dorsi muscle flaps, 3 latissimus dorsi myocutaneous flaps, 2 rectus abdominis muscle flaps, 3 omental flaps, 1 scapular flap, 1 radial forearm flap, and 1 groin flap. Twelve patients had acute or subacute wounds resulting from trauma or craniotomy, 4 had primary cancer, and 2 had neurofibromatosis. Commonly used recipient vessels were the superficial temporal artery and vein. No flap procedure had morbidity due to vessel compromise, and the overall flap success rate was thus 100%. No major donor-site morbidity was observed. All cases underwent primary closure of donor sites except for one receiving split-thickness skin grafting. In cases where muscle or omental free flaps covered skin grafts, patients were more satisfied because of increased durability and well-fitted wigs. We advocate variable free-tissue transfers for the reconstruction of large defects of the scalp related to the sizes, sites, and extents of the involvement.
