突聋措瞬间发生的或睡醒时出现的突然听力损失；听力损害在症状开始的数小时内发生。在造成突聋的多数原因中，循环障碍虽有组织病理学的证据，但临床上则难于诊断。为测定突聋伴椎一基底动脉慢血流（SBF）的特征，对57例突聋患者（男31，女26；年龄从12岁到76岁，平均52岁）作
Sudden deaf measures sudden or sudden wake-up hearing loss occurs; hearing loss occurs within a few hours of the onset of symptoms. Among the most common causes of sudden deafness, circulatory disorders are histopathologically evidence-based, but clinically difficult to diagnose. To determine the characteristics of sudden deafness associated with vertebrobasilar arterial insufficiency (SBF), 57 patients with sudden deafness (male 31, female 26; age 12 to 76 years, mean 52 years)
