畸变产物耳声发射在职业性听力损伤诊治中的应用

畸变产物耳声发射是一种针对耳蜗外毛细胞的检查,通过对它在职业性噪声聋的诊断、治疗、预防等方面作用的分析,得出它具有检测客观、方法简便、无创伤、敏感等特点,结合纯音测听检查,能帮助鉴别伪聋、夸大聋等职业病诊断工作中常见情况,帮助排除其他原因所致听力损害等,对职业性噪声聋的治疗和预防也有较好的作用,故在职业性听力损伤诊治中具有重要现实意义。

Application of DPOAE in diagnosis of occupational noise-induced deafness

DPOAE (distortion product otoacoustic emission) is a functional test of cochlear outer hair cells, which is a simple, non-invasive, sensitive and objective examination in audiological tests. In the occupational medicine area, combined with the pure tone test, it can be used for differential diagnosis of the pseudo deafness and exaggerated deafness, and to exclude the hearing damage caused by other factors. It is also useful to evaluate effectiveness of the treatment of deafness induced by occupational noise.
