Percutaneous radiofrequency thermocoagulation of gasserian ganglion under guidance of neuronavigation combined with electrophysiological monitoring for patients with primary trigeminal neuralgia

Objective To explore the clinical effect of percutaneous radiofrequency thermocoagulation of gasserian ganglion under guidance of neuronavigation combined with electrophysiological monitoring (PRT-NCM) on the patients with primary trigeminal neuralgia (PTN). Methods The clinical data of 38 patients with PTN who underwent PRT-NCM from March 2016 to June 2018 were analyzed retrospectively. Visual analogue scale (VAS) score was used to evaluate the pain before and 1 year after the operation. One year after the operation, the pain prognosis grade score of Barrow Institute of Neurology (BIN) was used to evaluate the pain prognosis, with effectiveness of grade Ⅰ~Ⅲ and no effectiveness of grade Ⅳ~Ⅴ. Results The success rate of first puncture was 92.1% (35/38). The VAS score (1.5±1.2) points] 1 year after the operation was significantly lower than that (8.5±1.0) points] before the operation (P<0.05). One year after the surgery, BNI grade Ⅰ was achieved in 29 patients, grade Ⅱ in 4, grade Ⅲa in 2, grade Ⅲb in l, grade Ⅳ in 1, and grade Ⅴ in 1; the effective rate was 94.7%(36/38). There were no serious complications such as intracranial hemorrhage, cerebrospinal fluid leakage and intracranial infection during the 1-year follow-up. Conclusions PRT is an effective treatment method for the patients with PTN. NCM can help to visualize the whole operation process, accurately locate the target of the gasserian ganglion, improve the safety and efficacy of the operation and reduce the complications of the operation.
