To examine the effectiveness and safety of ultrasound-guided glossopharyngeal nerve block via the styloid process for primary glossopharyngeal neuralgia.
This retrospective study included all patients receiving glossopharyngeal nerve block via the styloid process under ultrasound guidance for primary glossopharyngeal neuralgia between January 2015 and May 2018 at our hospital. The primary outcome of the study was pain relief as assessed using the visual analog scale (VAS). Treatment was considered effective if the VAS score decreased by more than 2 points.
Twelve patients were included in the analysis. The baseline VAS scores ranged from 5 to 9. All patients received previous pharmacotherapy. Other previous treatments included pulsed mode radiofrequency (n=4), microvascular decompression (n=2), and glossopharyngeal nerve block (not under ultrasound guidance; n=2). The patients completed a total of 48 injections for glossopharyngeal nerve block. At discharge from the hospital, and at 6, 12, and 18 months thereafter, 10/12, 10/12, 7/12, and 4/12 patients achieved pain relief and the effective rate was 83.3% at discharge, 83.3% at 6 months, 58.3% at 1 year, and 33.3% at 18 months, respectively.
Ultrasound-guided glossopharyngeal nerve block via the styloid process is a safe, radiation-free, repeatable, convenient, and effective treatment. It can provide a treatment option for patients with glossopharyngeal neuralgia.
探讨经茎突超声引导下舌咽神经阻滞治疗原发性舌咽神经痛的有效性和安全性。
本回顾性研究纳入了2015年1月至2018年5月在我院接受经茎突超声引导下舌咽神经阻滞治疗原发性舌咽神经痛的所有患者。研究的主要结局是使用视觉模拟量表（VAS）评估的疼痛缓解情况。如果VAS评分降低超过2分，则认为治疗有效。
12例患者纳入分析。基线VAS评分范围为5至9分。所有患者此前均接受过药物治疗。其他既往治疗包括脉冲模式射频治疗（n = 4）、微血管减压术（n = 2）和舌咽神经阻滞（非超声引导下；n = 2）。患者共接受了48次舌咽神经阻滞注射。出院时以及此后6、12和18个月时，疼痛缓解的患者分别为10/12、10/12、7/12和4/12例，出院时有效率为83.3%，6个月时为83.3%，1年时为58.3%，18个月时为33.3%。
经茎突超声引导下舌咽神经阻滞是一种安全、无辐射、可重复、方便且有效的治疗方法。它可为舌咽神经痛患者提供一种治疗选择。
