Trigeminal neuralgia	Overall: 175 patients
Sex distribution	Men: 72	Women: 103
Mean age (range)	62.3 years (20–89 years)
Mean duration of pain (range)	7.8 years (1–33 years)
Outcome	Immediately after surgery (175 patients)	Late follow-up at >1 year (113 pts.); mean, 53 months
No pain	155 (88.6%)	91 (80.5%)

Hypesthesia	5 (2.9%)

*Results from the authors’ own series of microvascular decompression surgery in 175 patients with trigeminal neuralgia. Pain relief immediately after surgery and on late follow-up is shown, as is the frequency of permanent morbidity (hearing loss and sensory loss)
