Abstract:
In 48 postoperative cases using ear-clinoidal line positioning in radiofrequency thermocoagulation for treatment of trigeminal neuralgia,observing its recurrence and postoperative pain and complications in a five-year review. The successful rate of puncturing one time was 100%. Pain disappeared completely in 46 cases with one therapy. Two cases alleviated pain and decreased outbreak times. No recurrence and postoperative complications were observed. The vertical distance between the needle tip and the ear-clinoidal line were confirmed 8-10 mm in the third branch, 6-7 mm in the twice branch, 4-5 mm in the first branch. In order to avoid the first branch of trigeminal nerve injury, the vertical distance must be less than 6 mm, and the needle tip can not exceed ear-clinoidal line.
