Mohs Micrographic Surgery for the Eyelid

The eyelid protects the eye from environmental insults and assists in keeping the cornea moist. At only 0.6 mm thick, the periorbital skin is one of the thinnest cutaneous surfaces of the body. Mohs micrographic surgery (MMS) offers advantages over other resection techniques for this area because it attempts to conserve tissue and preserve function. A thorough understanding of the anatomy of this area is paramount to avoid permanently damaging vital structures. The patient’s eye must be protected at all times.
