Objectives The objective of this study was to examine the long‐term outcome of percutaneous radiofrequency thermocoagulation ( PRT ) of the Gasserian ganglion for the 2nd division and multiple division trigeminal neuralgia ( TN ), compared to the isolated 3rd division TN . Methods One hundred and forty‐eight procedures performed in 89 patients with typical TN between April 2004 and September 2011 in a single pain center were retrospectively analyzed. Baseline characteristics of these patients, immediate outcome, duration pain‐free, and complications were obtained from their medical records and questionnaires sent in June 2012. Duration pain‐free was assessed by Kaplan–Meier analysis. Results Of the 148 PRT of the Gasserian ganglion, 37 procedures were performed for isolated 2nd‐division TN (V2 TN ), 67 procedures were for both 2nd‐ and 3rd‐division TN (V2 + V3 TN ), and 38 procedures were for isolated 3rd‐division TN (V3 TN ). The remaining 6 procedures were performed for V1 + V2 TN and V1 + V2 + V3 TN . Immediate success rates of PRT for V2 TN , V2 + V3 TN , and V3 TN were 100%, 86.6%, and 100%, respectively, whereas the durations pain‐free for V2 TN and V2 + V3 TN were significantly shorter than that for V3 TN (9, 12, and 36 months, respectively: P  = 0.012). Conclusion For 2nd‐division TN and multiple‐division TN , less long‐term pain relief after PRT of the Gasserian ganglion can be expected compared with that for isolated trigeminal 3rd‐division neuralgia, even if immediate pain relief is achieved.
