Forty patients with neurosensory hearing disorders of vascular genesis were examined and divided into two groups. Patients with tone hearing disorders in conventional (0.125-8 kHz) and extended (9-16 kHz) frequency ranges entered group 1, those with such disorders in the extended range--group 2. Patients of group 1 had more pronounced cardiovascular dysfunction. Control group consisted of 15 persons with normal hearing. Electroencephalography (EEG) has shown that initial neurosensory hearing disorders were accompanied with redistribution of the main EEG rhythms especially in group 1. Compared to controls, these patients demonstrated significantly (p0.05) reduced representation of alpha-rhythm while that of beta-activity rose showing involvement of cerebral cortical structures. Adequate preventive measures in patients with initial neurosensory hearing disorders of vascular genesis are able to protect such patients against development of neurosensory hypoacusis of vascular genesis. |
