CLINICAL VALUE OF VASCULAR COMPRESSION AT THE CEREBELLOPONTINE ANGLE

Purpose:To evaluate the vestibulocochlear symptoms and audiological findings in patients with radiologically detected vascular compression of abnormally localized vertebral artery at cerebellopontine angle. Materials Methods: Patients magnetic resonance imaging (MRI) an image due to angulated or lateralized included. The degree based on was noted by radiologist. patients’ medical records were independently reviewed presence tinnitus, hearing loss, vertigo results mean thresholds pure tone average (PTA), speech discrimination (SD) scores, V latency, I-V interpeak latency auditory brainstem responses (ABR) noted. Results: close relationship 28 MR scans. categorized as point nerve 5 patients, longitudinal 17, contact loop indentation 6. There no differences between ipsilateral symptom patterns all groups. In groups, PTA, SD ABR found abnormal compared contralateral but failed show statistical significance. Conclusion: suggest that there significant clinical value cochleovestibular nerve. unexplained dizziness tinnitus complaints, deciding cause angle discussing necessity decompression surgery will only be possible larger patient series.
