Although it is well recognized that collapse of the external meatus can mimic a conductive hearing loss in the test ear, attention must also be directed to the masked ear during masked bone conduction threshold testing. Failure to recognize collapse of the masked ear may result in a false air-bone gap in the test ear. Two such cases are presented and the mechanism analyzed. Suggestions as to identification and resolution of this problem are discussed.
虽然外耳道塌陷可模拟测试耳的传导性听力损失这一点已得到广泛认可,但在进行掩蔽骨导阈值测试时,也必须关注掩蔽耳。未能识别掩蔽耳的塌陷可能会导致测试耳出现假的气骨导差。本文介绍了两例此类病例并分析了其机制。还讨论了关于识别和解决该问题的建议。
