Crescentic Modification to Island Pedicle Rotation Flaps for Defects of the Distal Nose.

Abstract

Island pedicle flaps based on a lateral sling of the nasalis have difficulty reaching distal nasal defects due to tethering of the muscle to its insertion point. The authors hypothesized that reach could be improved by modifying a crescentic flap to rotate around a pivot point equidistant to the flap and the defect. To describe the design, execution, and results with a modified crescentic island pedicle rotation flap for repair of distal nasal defects after Mohs micrographic surgery. The authors performed a retrospective analysis of patients who had distal nasal defects repaired with a modified crescentic island pedicle rotation flap over an 8-year period. All charts and photographs were examined. Sex and age of the patient, type of cutaneous carcinoma, location and size of the defect, and complications were recorded. Forty-eight patients were included. The flap was used to successfully reconstruct defects on the distal nose ranging in size from 0.25 cm to 3.8 cm. Complications involved one wound infection and one episode of postoperative bleeding. The authors' modifications to the island pedicle flap may be reliably used to reconstruct small- to medium-sized defects of the distal nose in a single stage with minimal risk of complications.
