[Selective radiofrequency thermocoagulation for trigeminal neuralgia].
摘要
OBJECTIVE: To study the technique and experience of selective radiofrequency thermocoagulation (SRFTC) for trigeminal neuralgia (TN) and the application of neuronavigation in SRFTC for TN. METHODS: SRFTC was performed in 3269 TN patients and neuronavigation-assisted SRFTC in 36 of them. Follow-up was carried out for over 2 years in 1722 cases. RESULTS: An excellent efficacy was achieved in 2590 cases, a fair outcome in 548 cases and no response in 131 cases. The recurrence rates at one and two years were 10.5% and 25.0% respectively. The efficacy was excellent in all cases treated by neuronavigation-assisted SRFTC. The effective rate was 96%. Neither serious complication nor death occurred in this series. CONCLUSION: SRFTC for TN is both safe and effective. And the neuronavigation technique can not only increase the surgical efficacy of SRFTCP for TN but also decrease the surgical risks.
