Abstract: Objective: To evaluate the application value of the dermal-subcutaneous pedicled flap in the repair of facial wounds after skin tumor resection. Methods: A retrospective analysis was conducted on 65 patients with facial skin tumors who underwent extended tumor resection followed by dermal-subcutaneous pedicled flap repair at the Department of Dermatology, Jinhua Central Hospital, from August 2022 to December 2024. Meanwhile, 30 patients with facial skin tumors repaired by conventional adjacent flaps and 30 patients repaired by skin grafting were selected as control groups, and the differences in flap survival rate, scar score, and patient satisfaction among the three repair methods were statistically analyzed. Results: Among the 65 cases treated with dermal-subcutaneous pedicled flaps, the postoperative flap blood supply was excellent with no necrosis; one case of distal necrosis occurred in the conventional adjacent flap group, and one case of partial skin graft necrosis was observed in the skin grafting group. The scar scores (assessed by the Vancouver Scar Scale) were 2.72 in the dermal-subcutaneous pedicled flap group, 3.80 in the conventional adjacent flap group, and 4.47 in the skin grafting group, while the patient satisfaction scores were 9.03, 8.07, and 7.57 respectively. The dermal-subcutaneous pedicled flap group was significantly superior to the conventional adjacent flap and skin grafting groups in terms of scar aesthetics and patient satisfaction (Ps＜0.001), and the flap survival rate was comparable to that of the other methods (P=0.021). No tumor recurrence was observed in all cases during a follow-up period of more than 6 months. Conclusion: In the repair of surgical defects caused by head and neck skin tumors, the dermal-subcutaneous pedicled flap repair method offers high flap survival rate, minimal scarring, excellent aesthetic outcomes, and high patient satisfaction, making it a valuable clinical option.
