目的探讨舌咽神经痛的病因，提高治愈率。方法采用局麻下乙状窦后进路舌咽神经根显微神经血管减压术。结果３０例舌咽神经痛，２９例疼痛立即消失，１例无效者于术后１月行第２次手术治愈。术后随访０．５－６年，疼痛均未再发作。结论舌咽神经痛的病因主要为血管压迫舌咽神经根，而颈内静脉孔区蛛网膜增厚粘连造成舌咽神经根的无法缓冲，受其动脉搏动性的压迫敏感区是病因学基础。认为舌咽神经根显微血管减压术是一种解除病因的治疗方法，治愈率高，复发率低。
Objective To investigate the etiology of glossopharyngeal neuralgia and improve the cure rate. Methods Local anesthesia sigmoid sinus posterior approach glossopharyngeal nerve root microvascular decompression. Results 30 cases of glossopharyngeal neuralgia, 29 cases of pain disappeared immediately, 1 case of ineffective in January after surgery the second operation was cured. Follow-up 0.5-6 years after surgery, the pain did not recur. Conclusions The main cause of glossopharyngeal neuralgia is the vascular compression of the glossopharyngeal nerve root. The thickening of the arachnoid wall in the jugular foramen area results in the inability of the glossopharyngeal nerve root to be buffered, which is the etiological basis for the oppression of the arterial pulse. That the glossopharyngeal root canal microvascular decompression is a cure for the etiology, high cure rate, low recurrence rate.
