Abstract
Objective To explore the feasibility of CT location scan applied to treatment of trigeminal neuralgia by Gamma-knife. Methods A retrospective analysis was made to the clinical data of 12 cases with trigeminal neuralgia,who received CT location scan because of contraindication to MRI,hospitalized in the period from Oct. ,2010 to June,2013;the frame was fixed horizontally to prefrontal carina and occipital tuberosity with the base ring lower than external auditory meatus for about ﹥ 1 cm;the exit of trigeminal nerve root in the pons was decided in the CT location scanning image and gamma-knife treatment was performed with the isodose curve of 50% and the maximal dose of 84 to 90 Gy;postoperative follow-up by telephone was made and pain relief grading and facial numbness grading were evaluated. Results The trigeminal nerve root was well manifested in the CT scanning image;follow-up lasted from 6 months to 38 months with an average of 14 months;pain relief grade in 11 cases(91. 67% )dropped from grade Ⅳ and Ⅴ down to below grade Ⅲ,6(50. 00% )of the 11 had the complete relief of pain,the average time for effectiveness was 6 months(from 3 months to 10 months);facial numbness grade in 3 cases(25. 00% )were below grade Ⅲ. Conclusions The fixation of the frame horizontally to prefrontal carina and occipital tuberosity with the base ring lower than external auditory meatus for about ﹥ 1 cm avoids the metal artifacts and well-displays the trigeminal nerve root;CT location scan is a way of positioning in gamma-knife treatment for patients with contraindication to MRI.关键词
