Operative treatment of trigeminal neuralgia.
From January 1, 1986, to June 30, 1996, 240 patients were operated on for trigeminal neuralgia: 182 patients were treated by thermocoagulation of the gasserian ganglion after Sweet and 58 patients by decompression of the trigeminal nerve after Janetta. In the thermocoagulation group, followed up for 6 months to 10 years 95.2% of the cases showed freedom from pain, in the Janetta operation group, followed up for 6 months to 6 years 98.5% showed freedom from pain. Thermocoagulation is the preferred therapy, especially in older patients in whom general anesthesia is risky, while the Janetta operation is the therapy of choice in younger patients.
