This report is a follow-up study of 315 patients under 46 years old who suffered from trigeminal neuralgia and were treated by electrocoagulation of the Gasserian ganglion. The average foll-up period was 12.7 years, the maximum 33 years. Eighty percent had a return of pain, but 96.7% ultimately attained freedom from pain after repeat electrocoagulation.
