新疆维吾尔族耳鸣掩蔽曲线与掩蔽治疗效果的观察

Observation of Tinnitus Masking Curves and Effect of Masking Treatment in Uygur's Patients

目的观察维吾尔族耳鸣患者听力图及掩蔽曲线,探讨治疗效果及其相关性。方法对105例(118耳)耳鸣为主诉的维吾尔族患者进行纯音测试,根据听力图分为正常听力(32耳)、轻度听力损失(24耳)、中度听力损失(39耳)、重度听力损失(17耳)、极重度听力损失(6耳)5组。纳入对象均为维吾尔族耳鸣患者。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 105例(118耳)患者中,正常听力、轻度、中度听力损失组中耳鸣掩蔽曲线以重叠型为主;重度听力损失中耳鸣掩蔽曲线以间距为主。在所有病例中以重叠型和汇聚型居多。残余抑制试验在轻、中度听力损失组中均以重叠型阳性率高,与其他类型比较差异有统计学意义(P<0.05)。结论在耳鸣患者中存在心理焦虑的较多。因此心理暗示治疗和习服治疗尤为关键。耳鸣曲线的掩蔽不同所得到的后效抑制结果和耳鸣掩蔽治疗结果也不同。

Objective To analyze the audiogram and masking audiogram curve Uygur＇s patients with tinnitus,and to evaluate the effect of masking treatment.Methods The pure tone test were performed in 105 Uygur patients（118 ears） with tinnitus.Based on the audiogram,all patients were divided into five groups：normal hearing（32 ears）,mild hearing loss（24 ears）,moderate hearing loss（39 ears）,severe hearing loss（17 ears） and extreme hearing loss（6 ears）.The tinnitus test or masking treatment was chose according to Feldmann masking curves.Results In normal hearing,mild,moderate hearing loss group,overlapping tinnitus masking curve was the major part.In severe hearing loss group,the spacing tinnitus masking curve was the major part.In all cases,the overlapping and convergent was the major part.By taking residual inhibition test,the positive rate of overlapping tinnitus masking curve in mild and moderate hearing loss group was high,and the difference was significant as compared with other types（P0.05）.Conclusion There is more anxiety in tinnitus patients.Psychological treatment and acclimation treatment is particularly critical.The results of after-effect inhibition experiment and tinnitus masking treatment will be different according to tinnitus masking curves.
