Objective: The objective is to report the outcome of an anterior surgical approach to treat neuroma of the perineal branch of the pudendal nerve (PBPN). Patients and methods: An IRB-approved prospective study enrolled 14 consecutive male patients from 2011 through 2015 who had symptoms of perineal/scrotal pain. Each patient had a successful, diagnostic, pudendal nerve block. The surgical procedure was resection of the PBPN and implantation of the nerve into the obturator internus muscle. Mean age at surgery was 50 ± 15 years. Median duration of pain symptoms was 5.5 years (range 1.2–42.9 years). Mechanisms of injury was exercise (6/14), prostatectomy (4/14), and falls (4/14). Outcomes were the Male Pudendal Pain Functional Questionnaire (MQ), and the Numeric Pain Rating Scale (NPRS). Results: The mean postoperative follow-up was 26 ± 14 months. The MQ demonstrated that after surgery, patients overall had significantly less disability due to pudendal pain (P <.03). The NPRS revealed that pain significantly improved (P <.004). Conclusions: Resection of the PBPN and implantation of this nerve into the obturator internus muscle significantly relieved men's pelvic pain disability.
