Nasalis Island Pedicle Flap in Nasal Ala Reconstruction

Abstract

Defects of the nasal ala can be difficult to repair in a one-stage procedure. We describe a laterally based nasalis myocutaneous island pedicle flap to repair small but deep defects of the superior nasal ala. Objective To describe a single-stage flap for repair of small defects on the nasal ala that confines the repair to one cosmetic unit. Methods We discuss the anatomy of the flap and illustrate the method of placing the flap. Results We present several case examples and discuss potential applications of the flap. We also discuss the flap's limitations by citing an example of necrosis. Conclusions The nasalis myocutaneous island pedicle flap for repair of nasal alar defects is a new application of a one-stage procedure that yields excellent functional and cosmetic results. Knowledge of the limitations and the anatomy of the flap is crucial for a good outcome.
