摘要

背景:钆增强磁共振成像(MRI)是诊断前庭神经鞘瘤(VS)的金标准。本研究旨在比较低频、高频和平型突发性感音神经性听力损失(SSNHL)患者VS的发病率,并评估MRI对每种SSNHL类型的有效性。方法:我们分析了2014年1月至2020年3月在单一三级中心诊断为SSNHL的755例患者。所有患者均行颞骨MRI检查。我们使用逻辑回归来确定SSNHL类型与vs的关联。此外,我们进行了相关分析,以检验单词识别评分(WRS)与诊断时MRI测量的肿瘤大小之间的关系。结果:755例中有23例(3.0%)磁共振成像发现VS。其中123例(16.3%)为低频SSNHL;低频率SSNHL组与其他类型SSNHL的VS发生率差异有统计学意义(P < 0.001)。肿瘤初始大小与WRS呈显著负相关(r2 = 0.2905, P= 0.008)。结论:低频SSNHL患者中VS的发生率较低。听力损失的模式可以为肿瘤存在的可能性提供见解,从而有助于更有效的听力筛查和MRI检测VS的决策。

Temporal Bone Magnetic Resonance Imaging in Sudden Sensorineural Hearing Loss: Low Frequency Versus Other Types.

Background: Gadolinium-enhanced magnetic resonance imaging (MRI) is the gold standard for diagnosing vestibular schwannoma (VS). This study aimed to compare the incidence of VS among patients with low-frequency, high-frequency, and flat-type sudden sensorineural hearing loss (SSNHL) and to assess the effectiveness of MRI for each SSNHL type.

Methods: We analyzed 755 patients diagnosed with SSNHL at a single tertiary center between January 2014 and March 2020. All underwent temporal bone MRI. Logistic regression was used to determine the associations of SSNHL types with VS. Additionally, we conducted a correlation analysis to examine the relationship between word recognition scores (WRS) and the size of tumors measured on MRI at the time of diagnosis.

Results: Magnetic resonance imaging identified VS in 23 of 755 cases (3.0%). Of the patients, 123 (16.3%) had low-frequency SSNHL; none of these patients had VS. The incidence of VS differed significantly between the low-frequency SSNHL group and other SSNHL types (P < .001). A significant negative correlation was found between initial tumor size and WRS (r2 = 0.2905, P=.008).

Conclusion: The prevalence of VS was rare in patients with low-frequency SSNHL. The pattern of hearing loss may provide insights into the likelihood of tumor presence, thereby aiding in more effective audiometric screening and decision-making regarding MRI for detecting VS.
