AbstractThe treatment of trigeminal neuralgia by percutaneous retrogasserian glycerol rhizotomy was assessed in a series of 58 patients with a follow-up period ranging from 2 to 40 months postoperatively. All patients were considered medical failures prior to the procedure. Idiopathic trigeminal neuralgia was the diagnosis in 54 patients, and four patients had trigeminal neuralgia associated with multiple sclerosis. Forty-two patients (72%) reported complete relief from the procedure and are taking no medications. Four patients (7%) are much improved and require only minimal drug therapy. Twelve patients (21%) were considered treatment failures. The recurrence rate after initial relief of symptoms was 11%. Ten patients (17%) noticed a mild decrease in facial sensation following the procedure, and one additional patient had a profound sensory loss including loss of corneal reflex. The authors conclude that, while percutaneous retrogasserian glycerol rhizotomy may be useful in the treatment of trigeminal neuralgia, more clinical series and documentation of recurrence rate and complications are needed before any firm conclusions can be reached as to the efficacy of this therapy.
