目的 进一步了解多频率扫描声导抗测试对鼓室完整的中耳病变的诊断价值。方法 对正常耳 (2 3耳 )、听骨链固定 (2 0耳 )、听骨链中断 (18耳 )、分泌性中耳炎 (2 0耳 )进行了多频率扫描声导抗测试。结果 正常耳中耳共振频率为 10 41± 191.1Hz;听骨链固定耳中耳共振频率为 12 17.5± 199.5Hz ,较正常耳高 (P <0 .0 1) ;听骨链中断耳中耳共振频率为 6 2 2 .2± 15 3.6Hz,较正常耳及听骨链固定耳均低 (P <0 .0 1) ;分泌性中耳炎中耳共振频率为 42 7.5± 139.1Hz ,较前三者均低 (P <0 .0 1)。结论 多频率扫描带导抗测试对鼓膜完整的中耳病变的鉴别诊断有一定的参考价值
Objective To further understand the multi-frequency scanning acoustic conductivity test for the diagnosis of tympanic complete middle ear lesions. Methods The multi-frequency acoustic impedance tests of normal ear (23 ears), fixation of ossicular chain (20 ears), ossicular chain interruption (18 ears) and otitis media with otitis media (20 ears) were performed. Results The normal middle ear resonance frequency was 10 41 ± 191.1 Hz. The middle ear resonance frequency was 12 17.5 ± 199.5 Hz, higher than that of normal ear (P <0.01) The resonance frequency was 6222 ± 15 3.6Hz, which was lower than that of the normal ear and ossicular chain (P <0.01). The middle ear resonance frequency of otitis media with effusion was 42 7.5 ± 139.1Hz, Were lower (P <0.01). Conclusion The multi-frequency scan band conductivity test has certain reference value for the differential diagnosis of complete tympanic middle ear lesions
