Transcranial Doppler sonography in patients with Meniére's disease.
The aim of the study was to assess the correlation between pathologic vertebrobasilar (VB) findings obtained by the method of transcranial Doppler (TCD) sonography and hearing disorders in Meniere's disease patients. The manifestations of Meniere's disease were analyzed in 65 patients and correlated with transcranial Doppler of vertebrobasilar circulation. Control group consisted of 50 patients with cardiovascular dysfunction who had no hearing loss, tinnitus or vertigo, who were submitted to TCD examination. The control group of patients with cardiovascular dysfunction did not completely match the study group of patients with Meniere's disease. Statistical analysis showed a direct statistical significant correlation between the pathologic TCD findings of vertebrobasilar circulation and Meniere's disease. According to abnormal findings of TCD in 27.69% patients, we think that 28% of patients with Meniere's disease suffer from insufficient supply of the vertebrobasilar circulation. TCD is an objective method of choice for the vascular diagnosis of hearing loss in patients with Meniere's disease.
