耳鸣患者1/24倍频程精细化纯音测试结果分析

目的了解精细化匹配耳鸣位点与听损最大点之间的关系,分析耳鸣患者听力及临床特征与耳鸣的关系。方法对常频听力正常及异常组均进行1/24倍频程精细化纯音测听,寻找听损最大点及耳鸣位点;两组患者均进行病史分析,分析耳鸣患者听力及临床特征与耳鸣的关系。结果常频听力正常的患者38例行1/24倍频程精细化听力测试,检出听力损失者12例;两组患者127例均进行1/24倍频程听力精细化测试及耳鸣位点精细化评估,其中36例患者听力损失最大点和耳鸣位点一致。将常频听力正常组和异常组临床特征对比分析,常频听力异常组高血压、脑供血不足、睡眠障碍的发病率高于常频听力正常组。结论常频听力正常的患者行1/24倍频程精细化纯音测听可提高耳鸣声治疗的“靶向性”。

Analysis of 1/24 Octave Pure Tone Test on Tinnitus

Objective Our study used 1/24 octave pure tone test to find the maximum pitch of hearing loss,in order to learn the relations between the pitch of tinnitus and maximum pitch of hearing loss;to analyze the relationship between hearing and clinical characteristics in patients with tinnitus.Methods The research took 1/24 octave to find the maximum pitch of hearing loss and tinnitus pitch between normal pure-tone audiograms(PTA)test group and abnormal group.Results Our study detected 12 patients with hearing loss in 38 cases of normal PTA test.127 cases were tested by 1/24 octave,the maximum hearing loss pitch was consistent with tinnitus pitch in 36 patients.The incidence of hypertension,sleep disorder and insufficient cerebral blood supply in the abnormal hearing group was higher than that in the normal.Conclusion The“targeting”of tinnitus therapy can be improved by 1/24 octave pure tone test.
