Clinical efficacy of composite subcutaneous pedicled flaps in repairing full-thickness nasal alar defects of 11 patients: a clinical observation / 中华皮肤科杂志

ABSTRACT

Objective:To investigate clinical efficacy of composite subcutaneous pedicled flaps in repairing full-thickness nasal alar defects.Methods:Clinical data were collected from 11 patients with basal cell carcinoma of nasal ala in Department of Dermatologic Surgery, the Third People′s Hospital of Hangzhou from August 2019 to September 2020, and analyzed retrospectively. There were 6 females and 5 males, aged 70 years in average (range, 56-87 years) . After tumor resection, full-thickness nasal alar defects were formed, a flap was designed along the inner side of the cheek and turned by 180 degrees to repair the nasal mucosal lining; then, a subcutaneous pedicled flap was designed along the ipsilateral nasolabial fold to repair the outer secondary defects and postoperative defects.Results:The mean diameter of postoperative defects was 1.8 cm (range, 1.5-2.5 cm) , and the mean diameter of the nasal lining was 0.9 cm (range, 0.6-1.5 cm) . Seven days after the operation, stitches were removed, wounds healed without complications, and all flaps survived with a satisfactory appearance. The follow-up period ranged from 1 to 13 months (average, 6 months). After scar maturation, all patients were satisfied with the aesthetic outcome. No tumor recurrence was observed during the follow-up period.Conclusion:The composite subcutaneous pedicled flap is safe and effective for the repair of full-thickness nasal alar defects, and has advantages of a well-hidden donor site, good color match, and stage-I operation for reconstruction.
