Abstract
- Vascular compression in the root entry zone of trigeminal nerve at the brain stem is known as a cause of trigeminal neuralgia. After the first description of the neurovascular decompression method for trigeminal neuralgia in the posterior fossa by Dandy in 1934, several other authors reported good results with this method. Since September 1978, The authors performed 29 neurovascular decompression for trigeminal nerve in 27 patients and all patients had relief from the neuralgic pain. The trigeminal nerves were compressed by blood vessels in 21 cases, by tumor in 3 cases and by arachnoid adhesion in 1 case. But in 2 cases there were no lesions compressing the nerve.
