摘　　要：目的:初步探讨扩展高频用于评估地中海贫血患者早期听损伤的临床意义。方法:对2013-09-2014-11期间在我院接受治疗的60例(117耳)地中海贫血患者进行纯音测听(常规频率加扩展高频),观察治疗前后的听力改变情况。结果:60例(117耳)地中海贫血患者治疗前后的纯音听阈分别为(15.72±11.62)dBHL和(15.40±12.24)dBHL,差异无统计学意义(P>0.05);治疗后未检出率较治疗前升高,以18、19kHz最为明显,差异有统计学意义(P<0.05)。结论:扩展高频对地贫患者早期听损伤监测较常频听可能更敏感。Objective：To preliminarily explore the clinical significance of extended high frequency audiometry in evaluating the early hearing loss for thalassemia.Method：Pure tone audiometry（PTA）included conventional pure tone audiometry and extended high frequency audiometry were obtained on the pre and post-treatment day in60（117ears）patients from September in 2013 to October in 2014.Result：The averages of conventional pure tone audiometry for 117 cases were（15.72±11.62）dBHL on the pre-treatment day and（15.40±12.24）dBHL on the post-treatment day.There were no significant differences in PTA（P〉0.05）.But the hearing without detection rate was higher than before especially at 18 and 19kHz.The differences of the hearing without detection rate between the pre-treatment and the post-treatment day were statistically significant（P〈0.05）.Conclusion：The extended high frequency may be more sensitive in evaluating the early hearing loss for thalassemia.
