伴乙肝的耳鸣患者心理声学特征初探

A Preliminary Study of the Psychoacoustic Characteristics of Tinnitus Patients with Hepatitis B Virus

目的：初步探讨伴乙肝的耳鸣患者的心理声学特征，为此类人群制订更为个性化的耳鸣治疗方案提供临床依据。方法使用听尼特TM1000A耳鸣综合诊断治疗仪对35例伴乙肝的耳鸣患者进行纯音测听和耳鸣心理声学测试，对结果进行统计分析。结果35例患者中，听力正常组12例，听力损失组23例；耳鸣音调匹配失败5耳；耳鸣音调匹配类型以纯音为主（占68.6%）；耳鸣频率以高频居多（占70.0%）；耳鸣响度不大，以10 dB SL以内为主（占80.0%）；耳鸣佛德曼曲线在听力正常组与听力损失组均以汇聚型最多；残余抑制试验阳性率听力损失组（占70.0%）高于听力正常组（占50.0%）。结论伴乙肝的耳鸣患者，听力损失人数居多；汇聚型佛德曼曲线且伴听力下降的患者残余抑制试验阳性率最高，耳鸣更易被掩蔽。

Objective To explore the psychoacoustic characteristics of tinnitus patients with hepatitis B virus and to provide clinical evidences for the development of individualized tinnitus therapy. Methods Thirty-five tinnitus patients with hepatitis B virus received the pure-tone audiometry and tinnitus psychoacoustic assessment using a patented digital system, 1000A TinniTestTM. Results The 35 patients were divided into normal-hearing group（12 patients） and hearing-impaired group（23 patients）. 5 patients failed in the tinnitus pitch-matching test. The pitch-matching type was mainly pure tone（68.6%）. Tinnitus was present mostly in the high-frequency range（70.0%）. The tinnitus loudness was usually lower than 10 dB SL（80.0%）. The convergent Feldmann curve was mostly seen in both normal-hearing group and in hearing-impaired group. The positive rate of residual inhibition test for hearing-impaired group（70.0%）was higher than that for normal-hearing group（50.0%）. Conclusion A large proportion of tinnitus patients with hepatitis B virus suffer from hearing loss. The positive rate of residual inhibition test is highest in patients with convergent Feldmann curve and hearing loss, and the tinnitus is more likely to be masked for these patients.
