中文摘要：

目的：观察缺铁性贫血患者畸变产物耳声发射（DPOAE）的变化。方法：体检人群按血红蛋白及血清铁蛋白检查结果分组,正常对照组30例60耳,缺铁性贫血患者组30例60耳,分别行DPOAE检查,以4 kHz频率点为观察点。结果：缺铁性贫血患者的DPOAE幅值在4 kHz频率点较正常对照组下降,两者差异有统计学意义（P〈0.05）。结论：缺铁性贫血患者DPOAE幅值下降,可导致感音神经性聋。

英文摘要：

Objective：To observe the changes of distortion product otoacoustic emissions（DPOAE） in the patients with iron deficient anaemia（IDA）.Method：Sixty cases who were taken health physical examination at ZhaBei District Central Hospital were divided into two groups,the normal group（30 cases,60 ears） and the IDA group（30 patients,60 ears） depend on the results of examination of hemoglobin and serum ferritin.The changes of DPOAEs at 4 kHz were observed.Result：A statistically significant decrease of DPOAE threshold level compared with the normal controls was seen at 4 kHz in the patients with IDA.Conclusion：The decreased threshold level of DPOAE at 4 kHz in IDA patients should relate to sensorineural hearing loss directly.
