自从1981年Hakanson首次提出经皮三叉神经半月节注射甘油治疗三叉神经痛以来,对其疗效和面部感觉的影响仍有争论,作者对用此法治疗的122例患者进行了长期随访,并对其结果进行了分析。手术方法:所有患者术前均行头颅CT扫描,以除外器质性病变。手术在放射床上进行,患者取半坐位,使用20号腰穿针,局麻下经口角外侧穿刺卵圆孔,刺入深度通过荧光屏监视。看到脑脊液(csf)流出后,注射0.5ml碘肽葡胺(300mg/ml)进入三叉神经池,证实针尖到达适当位置后,缓慢注入消毒的纯甘油0.3～0.5ml,患者保持坐位或半坐位3～4小时。
Since Hakanson first proposed percutaneous trigeminal injections of glycerin in 1981 to treat trigeminal neuralgia, there is still debate about its efficacy and facial sensation. The authors followed 122 patients treated with this method for a long period of time, The results were analyzed. Surgical methods: All patients underwent cranial CT scan before surgery to exclude organic disease. Surgical operation on the radioactive bed, the patient take a half-seat, the use of No. 20 lumbar puncture, under local anesthesia, oral foramen ovale punctured, piercing the depth of monitoring through the screen. After seeing the flow of cerebrospinal fluid (csf), inject 0.5ml Ipomustine (300mg / ml) into the trigeminal nerve pool, confirming that the needle reaches the appropriate position and slowly inject sterilized pure glycerol 0.3 ~ 0.5ml, the patient to maintain the sitting or sitting position 3 ~ 4 hours.
