本文采用阈上听力测验、耳蜗电图、听性脑干反应技术对特发性突聋４７例（５２耳）进行听力学定位诊断研究。结果表明：耳蜗性病变３０耳（５７．６９％），蜗后病变２０耳（３８．４６％），耳蜗及蜗后联合病变２耳（３．８５％）。眩晕、听力障碍、听力图形、发病情况与病变部位无明显关系；伴否耳鸣及耳鸣音调高低与病变部位无明显关系，但如耳鸣为多种声音混杂者则蜗后病变可能性极大。听力损失较重者蜗后病变所占比例较高。阈上听力测验中音衰变试验（ＴＤＴ）可靠性较高，而ＡＢＬＢ、ＳＩＳＩ准确率低，实用价值不大。蜗后病变预后较差。
In this study, 47 patients (52 ears) with idiopathic deafness were diagnosed by audiometry using threshold supratentorial hearing test, electrocautery electrogram and brainstem response. The results showed that there were 30 ears (57.69%) with cochlear lesions, 20 ears (38.46%) with cochlear lesions and 2 ears (3.85%) with cochlear and cochlear lesions. There was no significant relationship between the tinnitus and the tinnitus tone and the lesion site. However, if the tinnitus is a multi-voice mixed, the possibility of post-cochlear lesion is very high. Hearing loss heavier cochlear lesions accounted for a higher proportion. Upper threshold hearing test mid-tone decay test (TDT) reliability, and ABLB, SISI accuracy is low, practical value is not. Post-cochlear disease prognosis is poor.
