    AbstractThis study reviews the results and complications of 162 percutaneous thermocoagulations of the gasserian ganglion in 124 patients with typical idiopathic trigeminal neuralgia. The mean duration of follow-up observation was 3.7 years (range, 1-6 years). One hundred eighteen of 124 patients continued to show complete pain relief 1 month after the operation, and at the end of follow-up observation, 83 of 124 patients (67%) continued to enjoy complete pain relief (recurrence rate, 28.2%). Anesthesia dolorosa occurred in 3% of cases, dysesthesia in 3%, and paresthesia in 17%; neuroparalytic keratitis with permanent reduction of visual acuity was observed in 2% of cases, permanent diplopia in 1%, permanent hearing deficit in 3%, and permanent impairment of mastication in 3%. We compare thermocoagulation with other surgical procedures (microvascular decompression, glycerol injection, and percutaneous decompression) used in the treatment of trigeminal neuralgia.
