摘要
目的：探讨前庭导水管扩大（EVA）和耳蜗发育异常、前庭耳蜗发育不良等内耳畸形间的关系。方法：回顾性分析郑州大学第三附属医院2010—2012年诊断为EVA的患者30例60耳。均行MSCT及MRI检查，评估EVA患者合并的其他内耳异常。结果：选取的60耳均患有EVA，双侧EVA 26例，单侧EVA 4例，12例女性和18例男性。平均年龄1.8岁（6月~4.2岁）。45（80.4％）耳EVA同时合并有一个或多个内耳异常。30（53.6％）耳合并耳蜗发育不良，9（16.1％）耳合并前庭耳蜗发育不良。结论：小视野、薄层MSCT和磁共振内耳水成像相结合，可以准确的发现EVA通常合并的内耳发育畸形，尤以耳蜗发育不良最常见。
Abstract
Objective: To investigate relationship between enlarged vestibular aqueduct(EVA) and inner ear malformations such as cochlear dysplasia, vestibulocochlear dysplasia and modiolus dysplasia. Methods: A retrospective analysis of 60 ears from 30 patients with EVA in the Third Affiliated Hospital of Zhengzhou University, between 2010 and 2012. MSCT and MRI were performed to assess the EVA inner ear abnormalities in patients with the other malformations. Result: The 60 ears were all suffering from EVA, bilateral EVA 26 cases, unilateral EVA 4 cases, 12 females and 18 males. The average age patients was 1.8 years(six month~4.2 years old). In 45(80.4%) ears with EVA also had one or more other inner ear abnormalities. Thirty ears(53.6%) associated with cochlear dysplasia, 9(16.1%) had vestibular dysplasia. Conclusion: According to small FOV, thin layer MSCT and magnetic resonance imaging of the inner ear, EVA is usually found to be comlicated inner ear malformations, particularly dysplasia of the cochlea.
