OBJECTIVE
This study was conducted to evaluate the frequency of inner ear anomaly in patients with sudden sensorineural hearing loss and in control subjects.
STUDY DESIGN
Retrospective case review.
SETTING
A tertiary referral center.
PATIENTS AND INTERVENTION
We evaluated 366 patients (165 men and 201 women; age range, 3-91 yr) with sudden sensorineural hearing loss and 228 control subjects without sensorineural hearing loss using magnetic resonance imaging. Three hundred fifty-six patients had unilateral and 10 patients had bilateral sudden sensorineural hearing loss.
RESULTS
Eleven (2.9%) of 376 ears with sudden sensorineural hearing loss had inner ear anomaly. Nine patients (2.5%) had inner ear anomaly associated with sudden sensorineural hearing loss, but none of the 228 control subjects had the anomaly. The current study demonstrated that the frequency of inner ear anomaly in patients with sudden sensorineural hearing loss was significantly higher than in control subjects.
CONCLUSION
Our study reveals that inner ear anomaly may be associated with sudden sensorineural hearing loss in 2.5% of patients.
目的
本研究旨在评估突发性感音神经性听力损失患者及对照受试者内耳异常的发生率。
研究设计
回顾性病例分析。
研究地点
一家三级转诊中心。
患者与干预措施
我们使用磁共振成像对366例突发性感音神经性听力损失患者（165名男性和201名女性；年龄范围3 - 91岁）和228名无感音神经性听力损失的对照受试者进行了评估。356例患者为单侧突发性感音神经性听力损失，10例为双侧突发性感音神经性听力损失。
结果
376例突发性感音神经性听力损失患者的耳朵中有11例（2.9%）存在内耳异常。9例患者（2.5%）的内耳异常与突发性感音神经性听力损失相关，但228名对照受试者中均无此异常。当前研究表明，突发性感音神经性听力损失患者内耳异常的发生率显著高于对照受试者。
结论
我们的研究表明，2.5%的患者内耳异常可能与突发性感音神经性听力损失有关。
