Several studies have reported sudden sensorineural hearing loss (SHL) as an initial symptom of acoustic neuromas (ANs).
AIMS/OBJECTIVES: We aimed to retrospectively evaluate the incidence of SHL and the associated rates of post-treatment improvement in patients diagnosed with ANs.
We analysed the clinical data of 686 patients with ANs and examined tumour size, correlation with hearing loss, number of episodes of SHL, extent of auditory recovery, and associated audiogram patterns.
Among 686 enrolled patients with ANs, 232 (86 with intracanalicular and 146 with extrameatal tumours) experienced SHL at some point in their clinical history. The incidence of SHL was not significantly associated with tumour size. Of the 172 patients analysed, 119, 44, and 9 patients experienced one, two, or three or more episodes of SHL, respectively. Confirmed auditory recovery occurred in 61%, 45.3%, and 33.3% of the patients after the first, second, or third or later episodes of SHL, respectively. The audiograms of 78/172 (45.3%) patients showed a typical trough-shaped pattern of hearing loss at medium-level frequencies.
Among patients with ANs, 7.7% experienced two or more episodes of SHL. The recovery rate of SHL decreased with each successive occurrence.
几项研究报告称突发性聋（SHL）是听神经瘤（ANs）的初始症状。
目的/目标：我们旨在回顾性评估诊断为 ANs 的患者中 SHL 的发生率以及治疗后听力改善的相关比率。
我们分析了 686 例 ANs 患者的临床资料，检查了肿瘤大小、与听力损失的相关性、SHL 发作次数、听觉恢复程度以及相关听力图模式。
在纳入的 686 例 ANs 患者中，232 例（146 例位于内听道和 86 例位于外听道）在其临床病史的某个阶段经历了 SHL。SHL 的发生率与肿瘤大小无显著相关性。在 172 例分析的患者中，分别有 119、44 和 9 例患者经历了一次、两次或三次或更多次 SHL。在首次、第二次或第三次或以后的 SHL 发作后，分别有 61%、45.3%和 33.3%的患者出现了明确的听觉恢复。在 172 例患者中的 78/172（45.3%）中，听力图显示出典型的中频谷形听力损失模式。
在 ANs 患者中，7.7%的患者经历了两次或更多次 SHL。SHL 的恢复率随着每次连续发生而降低。
