100 patients with hemifacial spasm treated by microvascular decompression
are presented. There were 60 females and 40 males. Their ages
ranged from 29 to 75 years with a median age of 54 years, and the left side was
involved predominantly. The common focal signs were facial nerve palsy in
41 cases, diminished hearing in 14 cases, trigeminal neuralgia in 11 cases, and
homolateral trigeminal neuralgia in four cases.
All of the patients underwent a lateral suboccipital craniectomy. In 96
cases of manifest vascular compression, the vessels were released and
isolated from the facial nerve using muscle. In those cases where veins,
adhesions, arachnoidal bridging or A. V .M. were responsible, the etiological
factor was approached.
The results of our patients are comparable with those reported by other
authors. The mortality rate was 2%.
