CT引导下颈侧入路舌咽神经毁损术

目的探讨CT引导下颈侧入路舌咽神经毁损术对舌咽神经痛及舌咽神经支配区顽固性疼痛的疗效. 方法 A组16例舌咽神经痛及B组12例舌咽神经支配区顽固性疼痛,采用CT引导经皮穿刺定位于茎突前缘第2颈椎水平,注入局麻药仅阻滞舌咽神经,注入7%苯酚甘油溶液0.8 ml. 结果 A组完全缓解率87.5%(14/16),总有效率100%(16/16),随访6个月无复发;B组完全缓解率50%(6/12),总有效率83.3%(10/12),随访6个月,复发6例(50.0%).2组均无严重并发症. 结论 CT介导下颈侧入路舌咽神经毁损术具有疗效可靠,定位准确,操作安全的特点,并有效减少严重并发症的发生.

CT-guided cervical approach neurolytic therapy of glossopharyngeal nerve

Objective To investigate the effects of CT-guided cervical approach neurolytic therapy of glossopharyngeal nerve in the treatment of glossopharyngeal neuralgia and intractable pain of glossopharyngeal nerve innervation area. Methods A total of 16 cases of glossopharyngeal neuralgia (Group A) and 12 cases of intractable pain of glossopharyngeal nerve innervation area (Group B) were included in this study. Under the guidance of CT scanning, a percutaneous needle puncture was carried out located on the anterior border of the styloid process at the level of the second cervical vertebra. The 7% phenol glycerin solution was injected after the glossopharyngeal nerve was blocked by the local anesthetic. Results The complete remission rate and the total effective rate in the Group A were 87.5% (14/16) and 100% (16/16), respectively. The corresponding values in the Group B were 50% (6/12) and 83.3% (10/12), respectively. Follow-up observations for 6 months found no recurrence in the Group A and 6 cases (50.0%) of recurrence in the Group B. No severe complications occurred in both of groups. Conclusions CT-guided cervical approach neurolytic therapy of glossopharyngeal nerve is characterized by high reliability, accurate location, good operational safety, and fewer complications.
