DZY-C型三叉神经立体定向仪治疗三叉神经痛的特点

背景经皮三叉神经半月穿刺损毁术是治疗原发性三叉神经痛的方法之一.因其穿刺技术操作上的难度,可导致误伤及一些严重的并发症.DZY-C型三叉神经立体定向仪治疗原发性三叉神经痛具有穿刺准确度高、并发症低等特点,可减少误伤周围血管、神经的机会.目的评价应用DZY-C型三叉神经立体定向仪治疗三叉神经痛的疗效.设计以患者为研究对象,前后对照研究.单位一所市级中医院的脑外科和一所市级医院.对象2001/2003佛山市中医院门诊或住院部就诊的原发性三叉神经痛患者90例,男39例,女51例;年龄21～90岁.干预所有患者按要求在DZY-C型三叉神经立体定向仪的引导下,经皮穿刺三叉神经半月节,注射甘油.疗效根据视觉模拟评分法(visual ana1ogue scale,VAS)在患者治疗前及治疗后30 min对疼痛程度进行评估.主要观察指标疗效评定结果.结果应用DZY-C型三叉神经立体定向仪,对90例原发性三叉神经痛患者进行三叉神经半月节穿刺,均一次穿刺成功,注射甘油后,原三叉神经疼痛消除90例,优良率达100%.结论DZY-C型三叉神经立体定向仪的结构设计合理,手术操作简易,调节灵活,组织损伤少,使用安全,可明显消除三叉神经痛.

Characters of DZY-C trigeminal nerve stereoguide in the treatment of trigeminal neuralgia

BACKGROUND: Trigeminal ganglion percutaneous puncture is one of the methods for the therapy of primary trigeminal neuralgia. The difficulties in percutaneous puncture technique and operation can lead accidental injury and some serious complications. The application of DZY-C trigeminal nerve stereoguide in the treatment of trigeminal neuralgia has the features of high accuracy in puncture and low complications, which can reduce the chances of accidental injury to surrounding vessels and nerves.OBJECTIVE: To evaluate the therapeutic effects of DZY-C trigeminal nerve stereoguide in the treatment of trigeminal neuralgia.DESIGN: A before-and-after experimental study based on patients.SETTING: Department of cerebral surgery of a municipal hospital of tradi tional Chinese medicine and a municipal hospital.PARTICIPANTS: Ninety patients including 39 male and 51 female patients with primary trigeminal neuralgia aged between 21 and 90 years old were selected from outpatient or inpatient department of Foshan Hospital of Traditional Chinese Medicine between 2001 and 2003.INTERVENTIONS: Glycerine was injected into trigerminal ganglion of each patient through percutaneous puncture under the guidance of DZY-C trigeminal nerve stereoguide. Therapeutic effects were evaluated by visual analogue scale(VAS) before and 30 minutes after the treatment.MAIN OUTCOME MEASURES: Results of therapeutic effects.RESULTS: Ninety patients with primary trigeminal neuralgia received trigeminal ganglion puncture with the application of DZY-C trigeminal nerve stereoguide. All punctures succeeded with one shot. After the injection of glycerine, the original trigeminal neuralgia disappeared in all 90 cases with the good and excellent rate of 100%.CONCLUSION: Trigeminal nerve stereoguide(DZY-C model) has the features of reasonable structural design, easy surgical operation, agile adjustment, less tissue injury, and safe manipulation, which can significantly eliminate trigeminal neuralgia.
