The nasalis myocutaneous island pedicle flap with bilevel undermining, a new method for repair of lateral nasal defects at or above the alar groove, yields excellent functional and cosmetic results. Bilevel undermining is a new and valuable method of achieving greater tissue mobility in muscle-based flaps.

This new feature will emphasize innovative and better ways to perform dermatologic surgery procedures. This article should be based on some evidence-based literature, but may describe the author's experience with a particular procedure without being a typical clinical research article.

The superiorly based nasalis myocutaneous island pedicle flap with bilevel undermining is a recently described bipedicled flap used for repair of nasal tip and supratip defects. This flap was used for the repair of small to mediumsize defects of the nasal tip and supratip regions.objective. To describe a single-pedicled modification of this flap for the reconstruction of lateral nasal defects at or above the alar groove. methods. With the use of diagrams and fresh cadaver dissection, we demonstrate the method of preparing, raising, and placement of this new flap. We further elucidate in an illustra-
