耳蜗死区在老年性聋患者中的初步临床分析
A preliminary analysis of cochlear dead regions in patients with presbycusis
摘要
Abstract
Objective To investigate the distribution of cochlear dead regions in patients with presbycusis. Methods Cochlear dead regions in 200 patients (370 ears) with presbycusis and 25 seniors (50 ears) with normal hearing were tested using the Threshold Equalizing Noise Test. Correlation of cochlear dead region data with degree of hearing loss, course of disease and hypertension in presbycusis patients was analyzed. Results Cochlear dead zone was detected in 76 of the 200 presbycusis patients (30%), and in 56 of the 124 presbycusis patients with hypertension (45%) (P<0.05). Cochlear dead zone was not found among those with normal hearing in contrast with the presbycusis patients (P<0.01). Cochlear dead zone detection also varied along with different levels of hearing loss and courses of disease (P<0.05). Conclusion Cochlear dead regions exist in individuals with presbycusis, and are correlated to the severity of hearing loss, length of disease course and coexisting hypertension.关键词
