[The current treatment of trigeminal neuralgia. Experience in 162 thermorhizotomies].
The neuralgia of the trigeminal nerve is the most frequent neuralgia of the cranial nerves. It is mostly seen in the elderly. In younger patients it must always be suspected as a symptomatic neuralgia. The course is recurrent and progressive. Spontaneous temporary remissions are usual. Later the pain becomes more frequent, unbearable and disabling. At first the therapy is a conservative one, the drug of choice is Carbamazepin, alternatively Phenytoin and Baclofen. If the conservative therapy fails, the only possible treatment is a neurosurgical one. Nowadays all methods aim at the Gasserian ganglion. In use are several percutaneous transoval procedures or the microvascular decompression through a craniotomy. Our surgical procedure of choice is the percutaneous thermorhizotomy in the Gasserian ganglion and the nerve root, where the pain-conducting fibers are destroyed, preserving tactile sensibility. This procedure is practically without vital hazards for the patient. It is applied in local anesthesia and a short intravenous analgesia. The recurrence rate of 32% is considerable, but the procedure can be repeated. The success cannot be deduced from the recurrence rate alone but must take into account the side effects of the procedure. These are mainly a loss of sensibility to touch by too aggressive rhizotomy and anesthesia of the cornea. By the criteria explained in the text we achieved a good result in 44%, a fair one in 25%, an indifferent one in 10% and a poor result in 7%. In 14% the result is unknown.
