Prolonged relief of tic douloureux from partial root destruction is associated with localized analgesia.

Fifty-eight patients who had been relieved of tic douloureux (TD) for least 3 years after partial destruction of the trigeminal sensory root by injection of minimal amounts of alcohol were reexamined 3 1/2 to 21 years after treatment. Of 41 patients still in remission at a median of 10 years after treatment, 32 had analgesia; i.e.

Effects of root or nerve destruction on vibrotactile sensitivity in trigeminal neuralgia.

Vibrotactile thresholds were determined at 7 frequencies between 25 and 300 Hz at the medial edge of the cheek in 11 patients who had been or were currently being treated for major trigeminal neuralgia, tic douloureux. A control group, comparable in age but without neural pathology, was also tested. Results indicate essentially no difference between normal and affected sides of the face prior to surgery.

Precise selective alcoholic Gasserian injection for tic douloureux. Recent advances in technic and results.

The Ecker-Perl method of alcoholic trigeminal rhizolysis has proved to be a safe and effective method of treating tic douloureux in a consecutive series of 324 patients over a period of 21 years.
