ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effectiveness of three-dimensional computed tomography (3D-CT) guided radiofrequency trigeminal rhizotomy (RF-TR) in treatment of idiopathic trigeminal neuralgia (ITN).</p><p><b>METHODS</b>From 1999 to 2001, 18 patients with ITN were treated with percutaneous controlled RF-TR. Intraoperative 3D-CT scanning was performed to guide the trajectory of the puncture. After correction of the needle tip according to the CT scans and stimulation effects, 2 to 5 lesions were made for a duration of 60-90 seconds at a temperature of 60 degrees C to 75 degrees C depending on the pain distribution and the age of patient.</p><p><b>RESULTS</b>The needles located in foramen ovale. Pain alleviated immediately with no serious complication in all patients. The patients were followed up for an average of 31.5 months (range 24-41 months). Acute pain relief was experienced by 17 patients after the procedure, reaching an initial success rate of 94.4%. Early (< 6 months) pain recurrence was observed in 2 patients (11.1%), whereas late (> 6 months) recurrence was reported in 3 patients (16.7%). Thirteen patients had complete pain control, with no need for medication thereafter. Five cases experienced partial pain relief, but required medication at a lower dose than in the preoperative period.</p><p><b>CONCLUSION</b>3D-CT foramen ovale locations can raise the successful rate of puncture, enhance the safety, and reduce the incidence rate of complication.</p>
