探讨血管压迫性耳鸣的发病原因及提高手术治疗的方法。方法：经乙状窦后径路进入桥小脑角，在手术显微镜下，对听神经周围仔细检查，发现３８耳第Ⅷ脑神经均有血管压迫，其中６耳伴有蛛网膜增厚粘连。将压迫或刺激听神经根的责任血管及粘连分开，并在神经与血管间夹放一块自体肌膜将其隔开。结果：术后３８耳耳鸣均完全消失。其中４例伴眩晕者术后眩晕亦消失。随访６个月～７年２个月，２耳耳鸣复发，３６耳痊愈。结论：血管压迫性耳鸣确诊后，采用乙状窦后径路神经血管减压术治疗，可以取得满意的疗效。
To explore the causes of vascular compression tinnitus and improve the surgical treatment methods. Methods: The posterior approach of the sigmoid sinus into the cerebellopontine angle, under the surgical microscope, carefully examined around the auditory nerve and found that 38 of the Ⅷ cranial nerves have vascular compression, of which 6 ears with arachnoid thickening adhesions. Will be oppressed or stimulate the auditory nerve root responsible vessels and adhesions separate, and between the nerves and blood vessels placed between a piece of self-muscle separation. Results: 38 ears of tinnitus disappeared completely. 4 of them with vertigo also disappeared after surgery. Followed up for 6 months to 7 years and 2 months, 2 ears tinnitus recurrence, 36 ears cured. Conclusion: The diagnosis of vascular compression tinnitus, the use of sigmoid sinus retrograde neurovascular decompression treatment, can achieve satisfactory results.
