Mohs surgery
Mohs Surgery, created by Dr. Fredrick E. Mohs, is microscopically controlled surgery that is highly effective for common types of skin cancer, with a cure rate of up to 99 or basal cell carcinoma, the most common type of skin cancer, and for squamous cell carcinoma. It has been used in the removal of melanoma-in-situ, but only by a few physicians. Because the Mohs procedure is micrographically controlled, it provides precise removal of the cancerous tissue, while healthy tissue is spared. For this reason, Mohs surgery results in a significantly smaller surgical defect and an improved cosmetic result compared to other surgical methods of skin cancer treatment. In certain area, especially the nasal tip, nasal ala, and the eyelids, radiation therapy can preserve viable tissue and result in better cosmetic appearance than Mohs surgery (See figure I, demonstrating the bilobed transposition flap with resulting visible scarring)
