摘　　要：对40耳声导抗检查为“C”型曲线患耳进行中耳系统共振频率点测试并进行鼓室穿刺抽液,结果表明:共振频率点低于600Hz,患耳鼓室积液阳性率为82.1%,高于600Hz患者鼓室和液阳性率16.7%,提示依据鼓室导抗图和共振频率点测定可初步判断“C”型曲线患耳鼓室积液的可能.A series ot multiple frequency test on acoustic immittance were performed on 40 ' type C' ears. The results showed that at auripuncture 23 ears or 82. 1% of the 28 effusion ears had resonance frequency less than 600 Hz.2 ears, or 16. 7% of the 12 effusion ears had resonance frequency higher than 600 Hz. It is apparent that there is a strong relation between resonance frequency and presence of effusion in 'tvpe C' ears.
