Mohs Micrographic Surgery is a highly specialized and precise surgical technique aimed at treating certain types of skin cancers, specifically those with high recurrence rates, located in critical areas, or those with ill-defined borders. It involves the systematic removal and examination of layers of cancerous tissue, providing highly accurate and detailed real-time analysis to ensure complete tumor removal while preserving as much healthy tissue as possible.
During the procedure, the surgeon first administers local anesthesia to the patient. Then, the visible tumor is carefully excised layer by layer with a scalpel, ensuring that the margins of each layer are clearly marked. After each layer is removed, it is immediately examined under a microscope by a trained dermatopathologist. This examination determines the presence or absence of cancer cells at the margins. If cancer cells are identified, further layers of tissue are selectively removed and examined until clear margins are obtained.
Mohs Micrographic Surgery offers several advantages over conventional surgical techniques. Firstly, it provides a higher cure rate, as the meticulous examination of each tissue layer reduces the chance of leaving any cancerous cells behind. Secondly, this technique maximally preserves healthy tissues, which is particularly significant in critical anatomical regions such as the face. Finally, the procedure facilitates immediate reconstruction if necessary.
Typically, Mohs Micrographic Surgery is performed in an outpatient setting, with same-day tumor removal and wound repair. Recovery is generally well-tolerated but may vary depending on the extent of the surgery. Follow-up care and regular skin checks are usually recommended to monitor for any recurrent or new skin cancers.
