Tinnitus and cerebrovascular disease

The auditory and vestibular systems share the same end organ and cranial nerve, yet vestibular signs and symptoms are common with cerebrovascular disease, whereas hearing disturbances are much less frequent. The most hemispheric lesions produce subtle hearing dysfunctions that can only be detected with sophisticated psychoacoustics and electrophysiological testing. The aim of this study was to evaluate the occurrence of risk factors for cerebrovascular disease in patients suffering from cochlear tinnitus. We tested 48 persons with subjective, cochlear tinnitus (patients), 35 women and 13 men, aged 30-65 years. Our results were compared to the control group of 50 persons without tinnitus, 36 women and 14 men, aged 28-66 years. All subjects had a complete neurootologix examination with medical history, standard blood testing, audiometry and vestibular testing. Colour Doppler Flow Imaging of carotid and vertebral arteries and Transcranial Doppler were also performed. Rezults The risk facotrs for cerebrovascular disease, hypertension, diabetes, hyperlipidemia and smoking were significantly more often in patients than controls. Patients with tinnitus had significantly more often the vertebrobasilar insufficiency evaluating by Transcranial Doppler. These results show that identification of risk factors for cerebrovascular disease may lead to prevention or effective treatment of cochlear tinnitus.
