Nasal Reconstruction Using a Myocutaneous Island Pedicle Flap Based on the Nasalis Muscle With Bilevel Undermining: Review of 57 Cases.

Background: Nasal reconstruction after Mohs resection of skin cancer commonly uses local flaps, many of which present limitations concerning their movement and skin color/texture match. In this article, the use of a myocutaneous island pedicle flap based on the nasalis muscle with bilevel undermining for the management of defects at challenging locations on the nose is described as a versatile and cosmetically appropriate flap option. In addition, a novel mathematical sizing methodology for this flap is presented.
