[Diagnosis and treatment of trigeminal neuralgia].

Trigeminal neuralgia is a disease affecting older individuals. The clinical hallmark of trigeminal neuralgia is a sudden, excruciating paroxysm of pain in the area of the trigeminal nerve. Drug therapy is considered the first line of treatment for trigeminal neuralgia. Anticonvulsant carbamazepine has been used. If relevant pharmacotherapy has been tried without any effect, other procedures are selected. These procedures are microvascular decompression(a radical technique), glycerol trigeminal rhizotomy, percutaneous trigeminal nerve decompression and nerve block. Nerve block with neurolytic solutions and radiofrequency thermocoagulation is a simple, less invasive therapy. In order to avoid hypesthesia and dysesthesia, nerve block using a high concentration of local anesthetics is recommended. In recent years, stereotactic radiosurgery for trigeminal neuralgia has emerged as a new therapeutic modality.
