Scalp and forehead reconstruction using free revascularized tissue transfer

Abstract

Objective: To examine the indications for, and the success of, free flap reconstruction in patients with forehead and scalp defects.

Design: Case series.

Setting: Two tertiary referral university teaching hospitals. Patients Twenty-six consecutive patients, aged 31 to 85 years, presenting with 26 scalp defects, 5 forehead defects, and 1 combined defect (size, 70-672 cm(2)). Three patients required resection and repair of the dura at surgery. Intervention Patients were staged according to the size of the defect and the viability of surrounding tissue; free flap reconstruction was performed where indicated.

Main outcome measures: Flap survival, complications, and disease-free and overall survival.

Results: Thirty-four free flap reconstructions were performed (24 latissimus dorsi free flaps, 4 scapular free flaps, 3 rectus abdominis free flaps, and 3 radial forearm free flaps). One failed 2 weeks postoperatively, and 2 required exploration (1 for arterial ischemia and 1 for a hematoma). There were 3 cases of donor site morbidity (2 early seromas and 1 late abdominal hernia). One patient died of a pulmonary embolus 1 week postoperatively. Disease-free survival was 48% at 5 years and overall survival was 59% at 5 years, with a median follow-up of 24 months.

Conclusions: Free revascularized tissue transfer is a reliable and safe way of reconstructing large scalp or forehead defects after traumatic injury or neoplastic resection. The muscle-only latissimus dorsi free flap for scalp reconstruction and the cutaneous scapular free flap for the forehead have proved successful in selected patients with a low complication rate and satisfactory cosmesis.
