Facial Defect Repair Using a Flap Based on the Superficial Temporal Artery.

[BACKGROUND] Although a local flap repair is optimal for facial defects, an extra flap or split-thickness skin graft may be needed if a sufficient local flap area is not available. In this study, we developed a distant axial pedicle flap procedure based on the inner transverse perforator of the ascending frontal branch of the superficial temporal artery to repair facial defects while meeting patients' requirements for a like-for-like tissue reconstructive outcome.

[METHODS] For defect repair after facial tumor removal, we designed upper frontal facial pedicle flaps based on the inner transverse perforator of the ascending frontal branch of the superficial temporal artery. Facelift procedures were applied concomitantly for donor site repair.

[RESULTS] We applied the procedure to 12 patients who underwent curative lesion resection. Notably, all flaps survived. Venous congestion developed in only 1 case, in which the wound was covered with heparin sodium gauze to inhibit wound coagulation until the congestion gradually resolved. In all cases, the frontal donor site scars were adjacent to the hairline and were concealed very well by hair growth. During postoperative follow-ups of 8-43 months, the patients experienced only minor complications.

[CONCLUSIONS] The flap based on the inner transverse perforator of the ascending frontal branch of the superficial temporal artery is a useful alternative for facial defect repair surgery. The low incidence of complications and easy concealment of the donor site underscore the safe and aesthetically acceptable nature of the procedure.
