摘要
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。
Objective:To evaluate the diagnosis and surgical indications of vascular compressive tinnitus. Method:We searched carefully the possible focus causing vascular compressive tinnitus around Ⅷ cranial nerve in cerebellopontine angle via retrosigmoid sinus approach under microscope in 40 cases. The responsible blood vessels and synechia focus was separated and one piece of auto-musculomembrane was put between blood vessels and the nerve. Result:We had 38 cases of operation. All of them had artery compression on the surface of Ⅷ cranial nerve, 6 of them had arachnoid synechia. After operation, the symptoms of tinnitus disappeared thoroughly. Of them 4 cases with vertigo recovered also. Recurrences were found in 2 cases in the follow-up survey which last 6 monthes to 7 years and 2 monthes. Conclusion: Surgical treatment of neurovascular decompression for vascular compressive tinnitus via retrosigmoid sinus approach has positive therapeutic effect as long as the diagnosis is correct.
