不同耳鸣掩蔽曲线与耳鸣治疗效果的关系

Clinical Observation of the Relationship Between Therapeutic Effect and Feldmann Masking Curves and Audiogram of Tinnitus

目的观察不同的听力图及掩蔽曲线耳鸣患者掩蔽治疗效果,探讨其相关性。方法对129例(164耳)耳鸣患者进行纯音测试,根据听力图分为正常听力(40耳)、传导性聋(10耳)和感音神经性聋(114耳)三组。按照弗德曼掩蔽曲线不同分别进行耳鸣测试及掩蔽治疗。结果129例(164耳)患者中,正常听力组中耳鸣掩蔽曲线以间距型(77.5%)为主;传导性聋组中,以间距型(30.0%)和拮抗型(30.0%)为主;感音神经性聋组中,以汇聚型(43.0%)为主,其次为重叠型(30.7%)。残余抑制试验在正常听力、感音神经性聋组中均以汇聚型阳性率高(分别为100.00%和96.00%),与其他类型比较差异有统计学意义(P<0.05)。耳鸣掩蔽治疗结果在正常听力和感音神经性聋组中以汇聚型有效率高(分别为100.00%和84.00%),与其他类型差异有统计学意义(P<0.05)。残余抑制试验与耳鸣掩蔽治疗结果呈正相关(P<0.01)。结论感音神经性聋伴耳鸣患者中以汇聚型耳鸣掩蔽曲线的患者有较好的后效抑制结果和耳鸣掩蔽治疗结果。残余抑制试验与耳鸣掩蔽治疗结果呈正相关。

Objective To study the relationship between therapeutic effect and Feldmann masking curves and audiogram of tinnitus. Methods One hundred twenty nine patients were divided into some groups according to audi ogram,Feldmann masking curves. They were tested for the residual inhibition and therapeutic efficacy of tinnitus therapy. Results There was significant deviation in the residual inhibition and therapeutic efficacy according to the Feldmann masking curves and the audiogram. Conclusion The convergence type and neurosensory deafness had the best residual inhibition and therapeutic efficacy.
