The objective of the present study was to determine the status of extended high frequencies in subjects with secretory otitis media. The study evaluated 30 ears of 20 subjects with secretory otitis media in the age group of 15-30 years. This data was compared with 20 ears of 10 volunteers of the same age group with clinically normal hearing. Pure tone air conduction thresholds were analyzed in three frequency groups: low frequency (LF: 0.25, 0.5, and 1 kHz), high frequency (HF: 2, 4, and 8 kHz) and extended high frequency (EHF: 10, 12, and 16 kHz). The results showed elevated extended high frequency thresholds (EHFG) as compared to control group and comparatively better thresholds at high frequencies(HFG)s as compared to low (LFG)and extended high frequencies(EHFG) in the study group. This validates the importance of including an extended high frequency audiometry in the test battery of patients with secretory otitis media.
本研究的目的是确定分泌性中耳炎患者的扩展高频听力状况。该研究评估了20名年龄在15至30岁之间的分泌性中耳炎患者的30只耳朵。将这些数据与10名同年龄组听力临床正常的志愿者的20只耳朵进行了比较。在三个频率组中分析了纯音气导阈值：低频（LF：0.25、0.5和1kHz）、高频（HF：2、4和8kHz）和扩展高频（EHF：10、12和16kHz）。结果显示，与对照组相比，研究组的扩展高频阈值（EHFG）升高，与低频（LFG）和扩展高频（EHFG）相比，高频（HFG）阈值相对较好。这证实了在分泌性中耳炎患者的测试组合中纳入扩展高频听力测定的重要性。
