| 摘 要： | 目的探讨先天性内耳畸形的高分辨率CT表现。方法回顾性分析29例(46耳)婴幼儿先天性内耳发育畸形患者的CT表现,所有患者均做多层螺旋高分辨率CT横断面扫描及多平面重建,必要者利用容积再现技术对骨迷路进行三维重建。结果29例先天性内耳发育畸形患者双侧畸形者17例,单侧畸形者12例,内耳发育畸形共计46耳。具体分布如下:(1)Michel型(2耳),(2)耳蜗未发育(6耳),(3)共同腔畸形(5耳),(4)不完全分隔Ⅰ型(5耳),(5)不完全分隔Ⅱ型(传统Mondini型)(17耳),(6)耳蜗形态正常仅前庭及(或)半规管畸形(9耳),(7)单纯内耳道畸形(2耳)。结论高分辨率CT对先天性内耳骨迷路畸形具有重要的诊断价值,并可为人工耳蜗植入术适应证的选择提供重要依据。
