The Clinical Analysis of 75 Patients which were Operated on MVD

ABSTRACT

A series of 75 microvascular decompression(MVD) for 23 cases of trigeminal neuralgia, 50 cases of hemifacial spasm and 2 cases of paroxysmal vertigo has been reviewed with assessment of outcome at the last follow-up examination. In hemifacial spasm, average of symptom duration was 7 years, and female had longer duration as trigeminal neuralgia. The offending site was found more frequent in right side of the trigeminal neuralgia and hemifacial spasm. Meaningfully female in hemifacial spasm and male in trigeminal neuralgia was noted more frequent in right side. The offending vessels were considered anterior inferior cerebellar artery and posterior inferior cerebellar artery in hemifacial spasm and superior cerebellar artery in trigeminal neuralgia. There were good or excellent results in 31 cases(62%) of hemifacial spasm and in 15 cases(65%) or trigeminal neuralgia. The serious complications were not occurred in both diseases except one who died of brainstem infarction.
