[Application of modified V-Y advancement flap for reconstruction of facial defect].

To investigate the clinical effect of modified V-Y advancement flap for reconstruction of facial skin defect. Thirty-eight patients with facial skin tumors underwent individual tumor resection according to pathological type and lesion depth. Based on the defect site and size, appropriate V-Y advancement flap was designed to reconstruct the skin defect in one stage. There were 9 cases of classic subcutaneous tissue pedicle V-Y advancement flap, 24 cases of modified subcutaneous tissue pedicle V-Y advancement flap and 5 cases of perforated V-Y advancement flap in our study. Among the 38 patients, 34 cases had primary healing. Two cases developed necrosis at the edge of the flap and healed after debridement. Local infection occurred in 2 cases, which healed after short-term dressing change. Postoperative mild eyelid ectropion occurred in 2 cases and oral horn displacement in 1 case. The patients were followed up for 6-36 months postoperatively, and the function and appearance recovered well. One case had local recurrence and 3 cases had parotid lymph node metastasis, which were removed again and supplemented with radiotherapy. The improved design of V-Y advancement flap can enlarge the scope of facial defect reconstruction, and achieve good appearance and function.
