The purpose of this study was to assess the audiological status of temporomandibular disorder (TMD) patients with otological symptoms and to make comparisons with that of a control group of subjects without TMD and otological symptoms.
25 TMD patients with otological symptoms and 20 age and gender matched controls, 45 subjects in total, were included in the study. All subjects underwent a series of audiological tests that included pure-tone audiometry, impedance test and reflex tympanometry. The audiological parameters recorded in the two groups were compared statistically by means of unpaired t tests and corrected according to Bonferroni in the case of repeated tests.
The pure-tone thresholds at frequencies 125, 250, 500Hz, and 6kHz showed significant differences between the TMD patients and control subjects after the Bonferroni correction (p<0.007). Compliance peaks demonstrated significant differences when the TMD and control groups were compared (p<0.05).
The findings indicate that TMD patients with otological complaints have hearing impairment at low frequencies and also perhaps, at high frequencies.
本研究旨在评估有耳科症状的颞下颌关节紊乱（TMD）患者的听力学状况，并与无 TMD 和耳科症状的对照组进行比较。
共纳入 25 例有耳科症状的 TMD 患者和 20 例年龄和性别匹配的对照组，共 45 例受试者。所有受试者均接受了一系列听力学测试，包括纯音测听、阻抗测试和鼓室反射测试。通过配对 t 检验对两组记录的听力学参数进行了统计学比较，并在重复测试的情况下根据 Bonferroni 进行了校正。
在 Bonferroni 校正后，TMD 患者与对照组在 125、250、500Hz 和 6kHz 频率的纯音阈值存在显著差异（p<0.007）。当比较 TMD 组和对照组时，顺应性峰值存在显著差异（p<0.05）。
研究结果表明，有耳科症状的 TMD 患者在低频和高频可能存在听力障碍。
