Abstract
Background: The alar and nasal tip are important subunits of the nose. Determining the optimal procedure for reconstructing a cutaneous defect in a nasal subunit depends on several factors including size, location, and involvement of deep underlying structures. We treated cutaneous defects after tumor ablation in the alar and nasal tip with a local flap, using an S-shaped design and a modified V-Y advancement flap with a croissant shape. Methods: We analyzed 36 patients with skin tumors who underwent flap coverage after tumor ablation. Rotation flaps were used in 26 cases and croissant-shaped V-Y advancement flaps were used in 10 cases. The primary cause of the defects was skin cancer, except for one benign tumor. Results: The mean patient age was 71 years. The size of the defects ranged from $0.49cm^2$ to $3.5cm^2$. No recurrence of skin cancer was noted and all flaps lasted until the end of follow-up. Partial desquamation of the epidermis was noted in one case. The postoperative appearance for most patients was excellent, objectively and subjectively. Conclusion: For cutaneous defects of up to about $4.0cm^2$ of the alar and nasal tip, local flaps using our methods offered a good cosmetic and therapeutic result. The main advantage of our flaps is the minimal dissection required compared to bilobed and other local flap methods. We believe our flaps are a suitable option for alar and nasal tip reconstruction.
