Recurrence Rates of Mohs Micrographic Surgery vs Radiation Therapy for Basal Cell Carcinoma of the Ear.

Basal cell carcinoma (BCC) of the ear may have aggressive histologic subtypes and a greater propensity for subclinical spread than BCC in other anatomic locations. In this retrospective analysis, we evaluated recurrence rates of BCC of the ear in 102 patients who underwent treatment with Mohs micrographic surgery (MMS) or radiation therapy (RT) at a single institution between January 2017 and December 2019. Data on patient demographics, tumor characteristics, treatment modality, and recurrence rates were collected from medical records. Recurrence rates were assessed over a mean follow-up time of 2.8 years. Although MMS is the gold standard for treatment of BCC of the ear, RT may be a suitable alternative for nonsurgical candidates.
