Sudden sensorineural hearing loss (SSNHL) has several aetiologies and may be a presenting symptom of vestibular schwannoma (VS).
The aim of this study was to investigate the recovery rate after steroid treatment and the prognostic factors of SSNHL with VS.
This was a retrospective observational study wherein 32 patients with VS who presented with SSNHL were analysed at a tertiary referral centre. Hearing gain and prognostic factors were the main outcome measures for steroid treatment intervention.
Among the 1698 patients presenting with SSNHL, VS was found in 43 (2.5%) patients. Eleven cases (34.3%) showed good recovery, with significant improvements in the pure-tone audiometry values. Even though age was a significant factor, there were no associations between steroid response and initial hearing level, presence of vertigo, tumour size, and tumour extension.
Our study showed that hearing recovery of SSNHL does not exclude a VS diagnosis. We suggest that steroid treatment be considered in patients with VS presenting SSNHL.
突发性感音神经性听力损失（SSNHL）有多种病因，可能是前庭神经鞘瘤（VS）的首发症状。
本研究旨在调查类固醇治疗后SSNHL合并VS的恢复率及预后因素。
这是一项回顾性观察研究，在一家三级转诊中心分析了32例表现为SSNHL的VS患者。听力增益和预后因素是类固醇治疗干预的主要结局指标。
在1698例表现为SSNHL的患者中，发现43例（2.5%）患有VS。11例（34.3%）显示良好恢复，纯音听力测定值有显著改善。尽管年龄是一个重要因素，但类固醇反应与初始听力水平、眩晕的存在、肿瘤大小和肿瘤扩展之间没有关联。
我们的研究表明，SSNHL的听力恢复并不排除VS诊断。我们建议对表现为SSNHL的VS患者考虑使用类固醇治疗。
