Low recurrence rate of head and neck basal cell carcinoma treated with Mohs micrographic surgery: A retrospective study of 1021 cases.

Objective: Mohs micrographic surgery (MMS) is the treatment of choice for high-risk primary basal cell carcinoma (BCC) and recurrent BCC of the head and neck, showing fewer recurrences compared with surgical excision (SE). The objectives of this study were to determine the recurrence rate of head and neck BCC after MMS and to develop a prediction model with significant risk factors for recurrence.

Design: A retrospective study of patient records.
