Objective: To evaluate the efficacy of CT-guided partial radiofrequency ablation of bilateral responsible cranial nerves in the treatment of Meige syndrome. Methods: The Clinical data of 56 patients with Meige syndrome in the Department of Pain Medicine, Affiliated Hospital of Jiaxing University from June 2019 to January 2023 were retrospectively analyzed [19 males and 37 females, aged 42-76 (58.6±8.3) years], including 51 cases of blepharospasm, 3 cases of oromandibular dystonia and 2 cases of blepharospasm concomitant with oromandibular dystonia. CT-guided partial radiofrequency ablation of bilateral responsible cranial nerves was performed on different types of Meige syndrome. And the efficacy and complications of the technique were observed. Results: Fifty-one patients with blepharospasm Meige syndrome underwent CT-guided radiofrequency of facial nerve through bilateral stylomastoid foramen punctures, the symptoms of blepharospasm disappeared completely, leaving bilateral mild and moderate facial paralysis symptoms. Three patients with oral-mandibular dystonia underwent CT-guided radiofrequency therapy by bilateral foramen ovale puncture of mandibular branches of trigeminal nerve, masticatory muscle spasm disappeared, the patients had no difficulty opening the mouth, and the skin numbness in bilateral mandibular nerve innervation area was left. Two cases of Meige syndrome with blepharospasm concomitant with oromandibular dystonia were treated by radiofrequency of facial nerve and mandibular branch of trigeminal nerve, and all symptoms disappeared. The patients were followed up for 1-44 months after the operation, and the symptoms of mild and moderate facial paralysis disappeared at (3.2±0.8) months after the operation, but the numbness did not disappear. Three patients with blepharospasm recurred at the 14, 18 and 22 months after the operation, respectively, while the rest cases did not recur. Conclusions: According to different types of Meige syndrome, CT-guided partial radiofrequency ablation of responsible cranial nerves can effectively treat the corresponding type of Meige syndrome. The complications are only mild and moderate facial paralysis which can be recovered, and/or skin numbness in the mandibular region.
目的： 观察CT引导下经皮穿刺双侧责任颅神经部分射频消融治疗Meige综合征的临床效果。 方法： 回顾性分析2019年6月至2023年1月嘉兴学院附属医院疼痛科56例Meige综合征患者临床资料，其中男19例，女37例，年龄42~76（58.6±8.3）岁。包括眼睑痉挛型51例，口下颌痉挛型3例，眼睑合并口颌痉挛型2例。不同痉挛类型患者分别接受CT引导下双侧责任颅神经部分射频消融治疗。观察该技术对不同痉挛类型Meige综合征的治疗效果和并发症。 结果： 51例眼睑痉挛型Meige综合征患者经CT引导下双侧茎乳孔穿刺面神经射频治疗后，眼睑痉挛症状完全消失，遗留双侧轻、中度面瘫症状。3例口下颌痉挛型Meige综合征患者经CT引导下双侧卵圆孔穿刺三叉神经下颌支射频治疗后，咀嚼肌痉挛消失，患者无张口困难，遗留双侧下颌神经支配区皮肤麻木感。2例眼睑痉挛合并口下颌痉挛型Meige综合征患者经面神经和三叉神经下颌支射频治疗后，所有症状均消失。术后随访1~44个月，患者轻、中度面瘫症状于术后（3.2±0.8）个月消失，麻木感均未消失。有3例眼睑痉挛型患者分别于术后14、18和22个月复发，其余患者均未复发。 结论： 根据Meige综合征的不同分型，采取CT引导下双侧责任颅神经部分射频消融可有效治疗相应类型的Meige综合征，并发症仅为可恢复的轻、中度面瘫和（或）下颌区皮肤麻木感。.
