Dr. Ritu Saini is a board certified dermatologist, specializing in Mohs micrographic surgery, cosmetic dermatology, dermatologic and laser surgery. Dr. Saini obtained a dermatologic surgery fellowship under the direction of world-renowned Mohs micrographic surgeon, Dr. Perry Robins.
Mohs Micrographic Surgery is a highly specialized surgical technique named after Dr. Frederic Mohs who invented the technique in the 1930s. The procedure is performed in our office under local anesthesia. Mohs is appropriate for certain high-risk tumors, as well as for those tumors that have occurred in cosmetically and/or functionally sensitive areas.
Unlike traditional surgery, Mohs removes skin cancer in successive stages until clear margins have been attained. After local anesthesia is administered, the clinically apparent tumor is removed with a small margin of normal-appearing skin. This tissue is then processed in our on-site laboratory, bisected, stained with multiple colors to preserve orientation, and placed on a slide. Dr. Saini will then examine the slide and determine whether there is any residual tumor at any of the margins. If residual skin cancer is identified, the location of the residual tumor cells is determined and additional stages are removed. This procedure proceeds until clear margins have been attained in every direction. Because of the immediate feedback, the surgeon is able to spare as much normal tissue as possible minimizing the final extent of the defect. Additionally, because of the special way in which the tissue is processed, the procedure is very precise and achieves a cure rate of 98 to 99%.
Depending upon the extent of the defect and its location, Dr. Saini will then discuss with you options for repair, including granulation (whereby the tissue is permitted to heal itself without sutures), a simple linear closure, a skin flap (utilizing adjacent tissue to cover the defect) or graft (borrowing distant tissue to repair the wound). A second visit for suture removal is typically required 1 to 2 weeks later.
Dr. Saini take great care to minimize scarring which results from Mohs surgery.
