Aesthetic Design of Expanded Bilateral Superficial Temporal Vascular Fascial Pedicled Flap for Repairing Maxillocervical Scars.

Background Large-scale maxillocervical scars impair face and neck function and damage appearance. The forehead expanded bilateral superficial temporal pedicled flap is a good treatment strategy for this area; however, the traditional cutaneous pedicled flap damages the temporal hair area. This impairs aesthetics and causes alopecia; furthermore, requires an additional pedicle-cut operation. Methods A retrospective study was performed on 7 patients with large-scale maxillocervical scars from January 2014 to August 2018. Forehead expanders were implanted in the first-stage operation for all patients. After the injection and rest period, patients were treated using the forehead expanded bilateral superficial temporal vascular fascial pedicled flap. Superficial temporal vascular fascia pedicles were carefully harvested. The use of an intralesional or hidden retrotragus incision was determined by the presence of a preauricular scar. Patient satisfaction with postoperative neck activity and the incision scar was evaluated. Results Intralesional and retrovagus incisions were used in 4 and 3 cases, respectively. One flap developed hematoma, which recovered completely after conservative treatment; all other cases had no complications. All flaps healed well. The neck mobility of the patients was significantly improved with no visible scar in the temporal region. Six cases reported being "very satisfied" and one was "relatively satisfied" with their improvement in neck mobility. All cases reported being "very satisfied" with frontotemporal morphology. Conclusions The forehead expanded bilateral superficial temporal vascular fascial pedicled flap is a good choice for patients with large-scale maxillocervical scars. This technique can maintain the aesthetics of temporal hair and reduce patients extra surgical injury.
