Mohs Surgery
Mohs Surgery is a highly specialized, tissue-sparing surgical technique designed for the precise removal of skin cancer while preserving as much healthy tissue as possible. Developed to maximize cure rates and minimize recurrence, this method involves staged excision combined with immediate microscopic examination of surgical margins. Recognized as a gold standard for certain high-risk tumors, Mohs surgery remains a critical topic at every international Dermatology Conference, where advancements in oncologic dermatology continue to refine patient outcomes. Closely associated with micrographic skin cancer surgery, this approach offers unmatched accuracy for treating basal cell carcinoma, squamous cell carcinoma, and select other cutaneous malignancies.
Unlike conventional excision, Mohs surgery evaluates 100 percent of peripheral and deep margins during the procedure itself. After removing a thin layer of tissue, the specimen is processed, mapped, and examined under a microscope. If residual cancer cells are detected, additional tissue is removed only from the precise area where tumor persists. This staged approach continues until clear margins are confirmed.
The session explores indications for Mohs surgery, particularly tumors located in cosmetically and functionally sensitive areas such as the nose, eyelids, lips, ears, and scalp. Aggressive histologic subtypes and recurrent tumors are also strong candidates for this method due to their unpredictable growth patterns.
Reconstruction following tumor clearance is equally important. Depending on defect size and location, options range from primary closure to local flaps and grafts. Aesthetic outcome and preservation of function remain central to surgical planning.
Complication prevention, including infection control, bleeding management, and scar optimization, is addressed alongside patient counseling regarding procedural expectations. Long-term follow-up ensures surveillance for recurrence or new primary lesions.
By combining meticulous microscopic control with precise surgical technique, Mohs surgery achieves superior cure rates while minimizing tissue sacrifice. This session provides clinicians with comprehensive insight into indications, execution, and postoperative management of this advanced oncologic procedure.
