Reconstruction of Cutaneous Nasal Alar Defects Following Melanocytic Nevus Resection.

OBJECTIVE

The reconstruction of nasal alar defects after resection of a melanocytic nevus becomes one of the most challenging procedures for surgeons. Choosing the most appropriate technique is still difficult sometimes. The authors reviewed our cases and published experience on choosing optimal surgical methods to repair different types of nasal alar defect following melanocytic nevus resection.

METHODS

A total of 152 patients who were treated between 2016 and 2019 in Shanghai Ninth People's Hospital were evaluated. The surgical methods included primary closure, full-thickness skin graft, composite auricular graft, interpolated melolabial flap, paramedian forehead flap including hair-bearing paramedian forehead flap.

RESULTS

Among the 152 patients with a melanocytic nevus, 49 underwent primary closure, 38 were treated with a full-thickness skin graft, 16 composite auricular graft, 28 were treated with interpolated melolabial flap, and 21were treated with paramedian forehead flap including 14 with hair-bearing paramedian forehead flap. Most skin graft, composite auricular graft, and flaps were survived. Patients who completed follow-up were satisfied with the contour of the nasal ala.

CONCLUSIONS

After resection of the melanocytic nevus, the surgeon should choose the most appropriate surgical method for alar reconstruction according to the characteristics of the defect and personal desire of patient or the guardian.
