Superficial temporal artery composite perforator flap in repair of temporal skin and soft tissue defects and reconstruction of sideburns

Abstract

To investigate the feasibility and effectiveness of repairing temporal skin and soft tissue defects and reconstructing sideburns with superficial temporal artery composite perforator flap. Between January 2018 and January 2019, 12 patients with temporal tumors were treated. There were 5 males and 7 females with an average age of 51 years (range, 37-68 years). There were 8 cases of basal cell carcinoma and 4 cases of squamous cell carcinoma. The disease duration ranged from 3 months to 4 years (mean, 13 months). The area of residual wound after tumor resection was 3.8 cm×2.5 cm-5.2 cm×3.5 cm. The superficial temporal artery composite perforator flap was designed. The hairy superficial temporal artery frontal branch perforator flap was used to repair the hair growing area and reconstruct the sideburn; and the area of the flap was 2.5 cm×1.0 cm-4.2 cm×3.0 cm. And the superficial temporal artery descending branch perforator flap without hair was used to repair the hair-free area; and the area of the flap was 2.5 cm×1.5 cm-7.5 cm×4.0 cm. The donor sites were sutured directly. All flaps survived, and the incisions at the donor and recipient sites healed by first intention. Eleven patients were followed up 6-12 months (mean, 9 months). The incisions were not obvious. The flaps were flat and the color of the flaps were not significantly different from the surrounding skin. The reconstructed sideburns were consistent with the healthy side and the facial appearance was satisfactory. No local tumor recurred during follow-up. For the temporal skin and soft tissue defects involving the sideburn, the superficial temporal artery composite perforator flap can be used to repair subunits with different aesthetic characteristics in sections and has the advantages of operating simply, obtaining satisfied facial appearance, and little effect on the donor site.
