摘要
目的探讨听觉脑干诱发电反应(auditory brainstem response,ABR)在职业性听力损伤诊断中的应用。方法对长期接触噪声并听阈明显下降的108名患者及108名正常体检人员进行纯音测听和ABR测试。结果听力损伤组与对照组纯音听阈测试,所有频区听阈值差异均有统计学意义(在语频听阈区,P<0.05;高频听阈区,P<0.01),以高频区听阈下降为主;108名患者216只耳中有172只耳ABR测听阈值结果与纯音测听阈值水平基本一致,占79.63%,与对照组比较差异有统计学意义(P<0.01);28只耳纯音测听高频听阈值高于ABR测听阈值,相差15(dB)以上,占12.96%;纯音测听高频听阈值低于ABR测听阈值的有16只耳,占7.41%;高频听阈值与ABR测听阈值进行相关性检验(r=0.57,P<0.01),呈正相关,而与语频听阈无相关性。结论噪声可造成听力损伤,ABR测试对职业性听力损伤的诊断有一定的帮助。
Objective To discuss the merit of application of auditory brainstem responses（ABR） on occupational noise induced hearing impairment diagnose. Methods The pure acoustic test and auditory brainstem responses test were respectively done on 108 patients with noise induced hearing impairment who were perennially exposed to noise（group one） and on as many as healthy ones（group two）. Results In the pure acoustic test of auditory threshold on two groups, the difference of auditory threshold had significance in the all frequency threshold （ in lower frequency threshold, P 〈 0.05, while in high frequency threshold, P〈0.01 ）, nevertheless, auditory threshold descending in high threshold was dominant; threshold level in ABR test was coincident with the threshold in pure acoustic test in 172 of 216 ears（79.63 % ） of 108 patients（ group one）, the difference had significance comparing to the healthy ones（group two）（ P〈0.01 ）, high frequency threshold level in pure sound was higher than threshold in ABR in 28 ears（ 12.96 % ）（the difference was above 15 db）, high frequency threshold level in pure sound was lower than threshold in ABR in 16 ears（7.41% ） ;positive relativity was verified between high frequency threshold and threshold in pure sound （ r=0.57, P〈0.01 ）, while lower frequency threshod and threshold in pure sound were no relative. Conclusion Noise can cause hearing impairment, and the auditory brainstem responses in the patients with noise-induced heating impairment is helpful for diagnose
