Abstract
Stereotactic radiosurgery (SR) is effective in managing trigeminal neuralgia (TN). Over the past 15 years, over 20,000 patients (world wide) have undergone SR for TN. SR is an outpatient procedure with no associated mortality and minor morbidity (generally new facial paraesthesia: 6–16.7%). Initial success rates range from 77 to 95% (generally within 2 days of SR). The benefit then declines to 55.8%–70% (at 3 years). SR can be repeated for recurrent TN (68‐85% benefit at 13.5–43 mths: 5 published reports; N = 111). Dunedin Public hospital holds the national contract for SR in New Zealand. Since 7.5.04, 6 patients with TN have been treated with SR in Dunedin (90 gray, 0.75 cm collimator, 7 table angles and 7 arcs). Details of this experience will be presented and discussed. A summary of the SR/TN literature will be given.
