BACKGROUND
With the development of inner ear gadolinium imaging technology, its clinical application is more and more frequent.
OBJECTIVES
To explore the application value of inner ear MRI after intravenous gadolinium injection in sudden sensorineural hearing loss.
MATERIAL AND METHODS
The clinical data of 28 patients who were preliminarily diagnosed with sudden sensorineural hearing loss and the results of intravenous gadolinium MRI examination were analyzed to find the relationship between them.
RESULTS
Of the 28 patients (30 ears) with idiopathic sudden sensorineural hearing loss, 20 (71.4%) showed normal MRI. MRI abnormalities related to hearing loss were found in 8 cases (28.6%), of which 5 cases (17.9%) showed hydrops in the inner ear membrane labyrinth, 2 cases (7.1%) showed mastoiditis on the affected side, and 1 case (3.6%) showed vestibular schwannoma.
CONCLUSIONS AND SIGNIFICANCE
Inner ear MRI after intravenous gadolinium injection can be used as an index to detect the cause of sudden deafness, one of the factors to guide clinical treatment, and an important means to further explore the relationship between hydrops of membranous labyrinth and SSNHL.
背景
随着内耳钆成像技术的发展，其临床应用越来越频繁。
目的
探讨静脉注射钆后内耳MRI在突发性感音神经性听力损失中的应用价值。
材料与方法
分析28例初步诊断为突发性感音神经性听力损失患者的临床资料及静脉注射钆MRI检查结果，以找出它们之间的关系。
结果
28例（30耳）特发性突发性感音神经性听力损失患者中，20例（71.4%）MRI表现正常。8例（28.6%）发现与听力损失相关的MRI异常，其中5例（17.9%）表现为内耳膜迷路积水，2例（7.1%）患侧乳突炎，1例（3.6%）表现为前庭神经鞘瘤。
结论与意义
静脉注射钆后内耳MRI可作为检测突发性耳聋病因的指标，是指导临床治疗的因素之一，也是进一步探讨膜迷路积水与突发性感音神经性听力损失关系的重要手段。
