Mohs' micrographic surgery of the periorbital area

Mohs micrographic surgery (MMS) provides one of the highest cure rates and may be more tissue sparing than other methods of surgical resection. It is a preferred treatment for most periorbital malignancies. The most common periorbital cancers treated with MMS include basal cell carcinoma, squamous cell carcinoma, and sebaceous carcinoma. MMS is not appropriate in certain circumstances for which other therapy such as wide local excision should be considered. A multidisciplinary combination of Mohs micrographic surgery, oculoplastic reconstructive surgery, and other medical and surgical specialties provides optimal patient care when treating periorbital cutaneous cancers. MMS for melanoma is controversial and not accepted at most centers due to the complexities encountered using frozen section histological evaluation. Modified MMS may be appropriate for some types of periorbital malignancy.
