老年性聋的临床听力学表现初步研究(附112例报告)

THE CLINICAL AUDIOLOGIC FEATURES OF PRESBYCUSIS

目的 :探讨老年性聋临床听力学表现及与耳蜗毛细胞损害的关系。方法 :对 2 0 0 1年 8月至 2 0 0 2年 7月间的 112例老年性聋病人进行临床听力检查并对结果进行分析。结果 :老年性聋男性 (6 5 .9% )较女性 (34.1% )高发 ,听力损害较女性重 ;耳声发射检出率低 (TEOAE的引出率仅为 7.14 % ,DPOAE引出率为 17% )。结论

Objective: To study the clinical audiologic features of presbycusis.Methods: 112 cases of presbycusis from August 2001 to July. 2002 were tested and analysed. Results: The prevalence of presbycusis was significantly greater in men(65.9%) than in women(34.1%), and the hearing levels in men were poorer than those in women; Only 7.14% of these cases had TEOAE, and 17% had DPOAE. Conclusion:Changes in incidence of Otoacustic emissions and pure tone threshold in the aged are thought to be attributed to hair cell loss in cochlea associated with age.
