We present a case study in which the jaw/mouth-open procedure during air-conduction testing is employed to both detect and remediate external auditory meatal collapse. A prospective investigation was also conducted to compare the efficacy of the proposed jaw/mouth-open procedure with that of the traditional insert receivers in remediating meatal collapse during audiologic assessment. Meatal collapse was present in 6 of the 136 subjects evaluated. In these 6 subjects, the air-conduction thresholds under supra-aural headphones in the jaw/mouth-open condition were similar to those under insert receivers. We discuss the implications of this finding in clinical settings where insert receivers are not available.
我们呈现了一个案例研究，其中在气导测试期间采用张口/开口程序来检测和纠正外耳道塌陷。还进行了一项前瞻性调查，以比较所提议的张口/开口程序与传统插入式受话器在听力评估期间纠正耳道塌陷的效果。在评估的136名受试者中，有6名存在耳道塌陷。在这6名受试者中，在张口/开口状态下使用 supra-aural 耳机时的气导阈值与使用插入式受话器时相似。我们讨论了这一发现对无法使用插入式受话器的临床环境的影响。
