Abstract
OBJECTIVES: To review Mohs micrographic surgery (MMS) trends in Saudi Arabia.Mohs micrographic surgery is a precise surgical technique that has been proven to have the highest cure rate with maximum normal tissue preservation. It is the treatment of choice for non-melanoma skin cancer (NMSC), especially the aggressive histopathological forms, and tumors located in high-risk regions or where tissue preservation is a mandate. METHODS: A multicentric retrospective study was performed on patients who underwent MMS between January 2010 and September 2022. The information was extracted from the database of King Saud University Medical City and Prince Sultan Military Medical City in Saudi Arabia. RESULTS: A total of 70 participants were enrolled in this study. Two-thirds (67%) of the tumors that were treated using MMS were basal-cell carcinomas (BCC), 18.6% were squamous cell carcinomas (SCC), 5.7% were sebaceous carcinoma, 4.3% were dermatofibrosarcoma protuberans (DFSP), and 1.4% were rare tumors such as primary mucinous carcinoma. The most common type of reconstruction used to repair post-MMS defect was primary closure in more than half of the patients followed by secondary intention healing (20%). There were no side effects apart from a hematoma in one patient and wound infection in two patients. CONCLUSION: Although MMS is still generally underutilized in Saudi Arabia, its use has increased in the last decade.
