药物耳毒性最先影响扩展高频听力范围(8～16kHz),逐渐影响语言频率(0.5～3kHz)。目前临床上对药物耳毒性的检测方法中,较为常用的有扩展高频测试和耳声发射两种。为探讨这2种方法的效果,我科听力中心对2001年1月～2004年10月在我院传染科使用链霉素治疗肺结核的20例患者进行了 Ear drug ototoxicity first expand the scope of high-frequency hearing (8 ~ 16kHz), and gradually affect the language frequency (0.5 ~ 3kHz). At present, the most commonly used method for detecting ototoxicity of drugs is to expand the high frequency test and the otoacoustic emissions. To explore the effectiveness of these two methods, our department of hearing center on January 2001 ~ October 2004 in our hospital infection department streptomycin treatment of pulmonary tuberculosis in 20 patients were
