Description
Summary:Background Mohs micrographic surgery has been considered the gold standard for treating nonmelanoma skin cancers. Approximately 8% to 10% of skin cancers requiring Mohs surgery occur on the auricle. Skin grafts can be used to achieve optimal functional and cosmetic results. Objectives To describe a skin graft technique using the mastoid area as a donor site for auricular reconstruction following Mohs micrographic surgery, to achieve optimal esthetic results in functionally important areas. Methods This retrospective study assessed the outcomes of patients who underwent MMS in an out-patient Mohs surgery clinic from 2010 to 2021. All patients had MMS of the auricle with reconstruction using a split thickness skin graft harvested from the mastoid area. Results A total of 154 patients were included. The average lesion diameter was 13.7 mm (range 5–30 mm), excised in an average of 1.9 rounds of MMS. Skin graft success rate was 96%. Complications included one patient with a hypertrophic scar. The cosmetic appearance of the recipient site was rated as excellent by 87.5% of patients. All patients rated the cosmetic appearance of the donor area as excellent and well-concealed. Conclusions Split thickness skin grafts harvested from the mastoid area are a quick and efficient reconstruction method for post-Mohs auricular defects.
