Sudden Sensorineural Hearing Loss (SSHL) was commonly seen in middle aged people. Tinnitus was reported by 87.2% of the patients, and dizziness or vertigo were reported by 48.5%. The most common concomitant disorder of SSHL was hyperlipidemia.
A retrospective register study with SSHL was performed in Xi'an, China, from 2000-2009.
Of 617 inpatients, the right ear was affected in 267 cases, the left ears in 282 cases, and both ears in 68 cases. The most common age of patients was 41-50 years. There were 20.4% SSHL patients with hypertension, coronary artery disease, or diabetes, and 49.6% patients with hyperlipidemia. Auditory Brainstem Responses (ABR) were performed in 460 patients (504 ears) before treatment, and the ABR threshold of 56.4% ears was > 90 dB. The constituent ratio of patients with an ABR threshold over 90 dB was greater in the vertigo group than the other group. CT and/or MRI scans were available in 277 cases, of which 40 cases (14.4%) were abnormal.
突发性感音神经性听力损失（SSHL）常见于中年人。87.2%的患者报告有耳鸣，48.5%的患者报告有头晕或眩晕。SSHL最常见的伴随疾病是高脂血症。
于2000年至2009年在中国西安进行一项关于SSHL的回顾性登记研究。
617例住院患者中，右耳受累267例，左耳受累282例，双耳受累68例。患者最常见的年龄为41 - 50岁。20.4%的SSHL患者患有高血压、冠状动脉疾病或糖尿病，49.6%的患者患有高脂血症。460例患者（504耳）在治疗前进行了听性脑干反应（ABR）检查，56.4%耳的ABR阈值>90 dB。眩晕组ABR阈值超过90 dB的患者构成比高于其他组。277例患者进行了CT和/或MRI扫描，其中40例（14.4%）异常。
