    Author: Xu Z, Xiong Y.
    Journal: Lin Chuang Er Bi Yan Hou Ke Za Zhi; 1999 Apr; 13(4):155-6. PubMed ID: 12563989.
    Abstract:
    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.
