Mohs micrographic surgery for facial skin cancer

Although it is well established that conventional treatment modalities generally result in high cure rates for non-melanoma skin cancer, it has been demonstrated over recent decades that the highest overall cure rates are achieved using Mobs micrographic surgery. The key to Mobs surgery is the excision and control of complete peripheral and deep resection margins in one plane, allowing orientation, mapping and re-excision of microscopic tumour extension. These extensions can be followed without sacrificing inappropriate amounts of normal tissue, yielding high cure rates and maximum preservation of tissue. These qualities make Mobs surgery an important and reliable treatment for skin cancer of the face, in particular when it concerns large, aggressive or recurrent carcinoma in cosmetic and functionally important areas. In an 8-year study period, 369 basal cell carcinomas (BCCs) and 56 squamous cell carcinomas (SCCs) of the face were treated in our department using Mobs surgery. With a follow-up ranging from 3 months to 99 months (mean 33 months), none of the BCCs recurred and only one (2%) of the SCCs recurred a few months postoperatively. These favourable cure rates using the modality of Mobs surgery are the reason for highlighting this technique in the current review.
