Oblique advancement flap for defects of the lateral nasal supratip

Background: Reconstruction of nasal alar defects is difficult because of the complex anatomy of the region. A frequent challenge in this area is repair of small cutaneous defects involving the lateral nasal supratip and the superior alar groove. Observations: An oblique advancement flap that uses laxity from the nasal sidewall is described. Its benefits and limitations are compared with those of alternative closures. Overall, the oblique advancement flap preserves the superior alar groove, while minimizing tissue contortion. It is technically similar to a primary closure but functionally and aesthetically superior. Conclusions: For selected small lateral nasal supratip defects impinging on the superior alar groove, the oblique advancement flap offers a simple, visually pleasing repair that preserves the alar architecture.
