Cheek Donor Site for Full-Thickness Skin Graft Repair of the Nasal Ala: Outcomes of a Retrospective Cohort Study.

ABSTRACT

BACKGROUND: Full-thickness skin grafts (FTSGs) are useful repairs for reconstructing nasal alar defects. Traditional donor sites include the preauricular, postauricular, and supraclavicular skin. OBJECTIVE: To evaluate esthetic outcomes and complications of nasal alar defects repaired with FTSGs from the medial cheek. MATERIALS AND METHODS: A retrospective chart review of Mohs surgery patients who had FTSG repair of the nasal ala between January 2015 and August 2020 was performed. Demographic, surgery, and follow-up visit data were reviewed. Cosmesis was rated by a facial plastic surgeon, a Mohs surgeon, and a plastic surgeon using baseline, defect, and follow-up visit photographs. RESULTS: Sixty-nine patients with FTSG repairs of nasal alar defects were identified. 51 of 69 patients (73.9%) had the cheek donor site, and 18 of 69 patients (26.1%) had a noncheek donor site. The mean (SD) rater visual analog score for both cohorts was good with no significant difference (cheek 65.9 [13.8]; noncheek 66.1 [15.3]; p = .96). A notable difference in the complication rate by donor site was observed (cheek 6.9%, noncheek 16.7%; p = .13), although it did not reach significance. CONCLUSION: The cheek is a reliable FTSG donor site for nasal alar defects after Mohs micrographic surgery, with a trend toward fewer complications.
