Abstract:
Most trigeminal neuralgia (TN) studies focus on a single strategy, microvascular decompression (MVD) or percutaneous rhizotomy (PR). We use a multimodality approach to TN. We perform MVD on patients younger than 70 years and PR on older patients or those where MVD has failed. We performed a chart review of the procedures for TN over the past 3 years and used a questionnaire for long-term follow-up. The questionnaire asked patients to rate their pre- and postoperative pain, outcome, and medication changes. Seventy-four procedures (40 MVDs and 34 PRs) were performed on 67 patients. Twenty patients had undergone previous procedures. 93% of the patients had significant initial pain relief. Over a 1.2-year mean follow-up, 51% of the patients had complete pain relief while 27% had a substantial improvement. There were no deaths and 5 complications. Our results suggest that a multimodality approach to TN yields excellent results with minimal complications.
