Collapse of the external auditory meatus during audiometry can lead to spuriously increased hearing thresholds being obtained, particularly at high frequencies, and may simulate conditions such as noise-induced hearing loss, presbyacusis and retrocochlear pathology. Consequently, inappropriate investigations and management may be undertaken. Two patients with elevated thresholds secondary to ear canal collapse are described. The implications of initially failing to identify the true nature of their 'hearing losses' are highlighted and strategies to avoid such pitfalls are discussed.
听力测试期间外耳道塌陷可导致获得假性升高的听力阈值，尤其是在高频时，并且可能模拟诸如噪声性听力损失、老年性聋和蜗后病变等情况。因此，可能会进行不恰当的检查和治疗。本文描述了两名因耳道塌陷导致阈值升高的患者。强调了最初未能识别其“听力损失”的真实性质的影响，并讨论了避免此类陷阱的策略。
