Radiofrequency Stimulation of the Trigeminal Complex in TIC Douloureux and Atypical Facial Neuralgia: Temporary Percutaneous and Permanent Methods

Abstract

Two patients with multiple sclerosis, one with recurrent severe intractable Tic Douloureux and one patient with atypical facial neuralgia have been managed by percutaneous placement of electrodes at the foramen ovale. In the latter patient, pain relief was effective but not complete while stimulation was present. The electrode system was removed because of infection and pain returned. In patients with Tic Douloureux there was total abolition of pain with stimulation. Inductively coupled radiofrequency stimulation was permanently accomplished by conversion of the percutaneous electrode system. Some of the potential implications of the procedure are mentioned. The probability exists that this may indeed be a very excellent method to employ increasingly in the future in patients with Tic Douloureux.
