Necrosis of the Ear Following Skin Cancer Resection

Abstract

We report 2 patients who underwent Mohs micrographic surgery (MMS) and operative closure on the ear. Both cases were complicated by necrosis resulting in the formation of auricular defects. These cases highlight the importance of the auricular vasculature and the associated watershed regions during operative planning for MMS as well as the complications that can arise with vascular compromise. This case report also provides a review of the auricular vasculature with special attention to these vulnerable watershed regions.
