To explore the rule of extended high-frequency (EHF) audiometry recovery in patients with acute otitis media.
From January 2016 to July 2019, patients with acute otitis media in the outpatient department of otology were studied. The diagnosis was made according to the otoscopy and acoustic impedance tests, and antibiotics and other treatment programs were given. The patients were followed up to compare the effects of different recovery time on extended high-frequency audiometry in patients with acute otitis media.
146 patients with acute otitis media (69 in the left ear and 77 in the right ear) were selected for observation and follow-up. The patients were divided into three groups according to the time from the onset to the disappearance of hyperacusis and earache symptoms: ≤ 5 days group (26 patients, 17.8%), 6-10 days group (74 patients, 50.7%), and > 10 days group (46 patients, 31.5%). The threshold of EHF in the study group was significantly higher than that in the control group in the early stage. According to the study design for follow-up, we found that with the prolongation of the duration of acute otitis media, the extended high frequency of different groups had different changes.
Our results show that the recovery time of EHF in patients with acute otitis media was later than that of the standard audiogram and was closely related to the course of the disease. This is of great significance for discovering the hidden hearing loss of the patients and taking the treatment plan as soon as possible.
探讨急性中耳炎患者扩展高频（EHF）测听恢复的规律。
选取 2016 年 1 月至 2019 年 7 月在耳科门诊就诊的急性中耳炎患者，根据耳镜和声阻抗检查诊断为急性中耳炎，并给予抗生素等治疗方案，通过随访比较不同恢复时间对急性中耳炎患者扩展高频测听的影响。
共观察随访 146 例（左耳 69 例，右耳 77 例）急性中耳炎患者，根据自发病至耳痛、耳闷胀感消失时间将患者分为三组：≤5 d 组（26 例，17.8%），6-10 d 组（74 例，50.7%），>10 d 组（46 例，31.5%）。研究组 EHF 阈值在早期明显高于对照组。根据随访设计研究发现，随着急性中耳炎病程的延长，不同组的扩展高频有不同的变化。
我们的研究结果表明，急性中耳炎患者 EHF 的恢复时间晚于标准听力图，与疾病的病程密切相关。这对于发现患者的隐匿性听力损失和尽早采取治疗方案具有重要意义。
