RESUMO
Objective:To investigate the clinical effect of repairing postoperative nasal skin cancer defect with subcutaneous pedicle flap based on partition and blood supply.Methods:From March 2018 to September 2020, 39 patients with skin cancer (basal cell carcinoma, Bowen′s disease, squamous cell carcinoma and malignant melanoma in situ) were repaired with kites subcutaneous pedicle flap after extensive resection.Results:Thirty-nine patients were treated with parafasal kite flaps, including 44 cases. The donor sites of the flap were nasal tip in 4 cases, bilateral alar in 7 cases, bilateral nasolabial sulcus in 19 cases, bilateral parasinal in 12 cases and interglabellar in 2 cases. There were no serious complications such as necrosis, hematoma or infection. During the follow-up period of 6 to 24 months, 2 patients complained of occasional tingling in the surgical area, 1 complained of occasional pruritus, and 1 patient had local recurrence of squamous cell carcinoma and underwent surgery again. The scar was evaluated 6 months after surgery, and the scores of Vancouver scar scale and visual analogue scale were 2.42±1.04 and 7.83±1.21, respectively. The skin color of the operation area was similar to that of the surrounding skin without obvious local strain deformation.Conclusions:The subcutaneous pedicle flap designed by considering the nasal division and blood supply has a high survival rate, fewer complications and small local appearance deformation, which is worthy of popularization and application.
