| 目的 探讨高分辨CT MPR显示面神经管迷路段与耳蜗解剖关系的能力。方法 选取于我院接受鼻窦高分辨CT检查的患者110例（220只耳），将原始图像传至后处理工作站，对图像进行MPR，观察面神经管迷路段与耳蜗中转的解剖关系，评价内容包括骨性间隔明确缺失（Ⅰ型）、骨性间隔可疑缺失（Ⅱ型）及骨性间隔完整（Ⅲ型）。结果 面神经管迷路段与耳蜗中转的解剖关系：Ⅰ型71只耳（71/220，32.27%），缺失最大径为0.3~1.3 mm，平均（0.64±0.26）mm；Ⅱ型86只耳（86/220，39.09%）；Ⅲ型63只耳（63/220，28.64%），骨性间隔厚度0.3~1.0 mm，平均（0.68±0.15）mm。不同性别、年龄及侧别之间上述3型解剖关系的出现率差异无统计学意义（P均> 0.05）。结论 高分辨CT是清晰显示面神经管迷路段与耳蜗中转解剖关系的可靠方法。 |

| Objective To investigate the value of high resolution CT (HRCT) in displaying the anatomic relationship between labyrinth segment of facial canal and cochlea. Methods Totally 110 patients (220 ears) who underwent HRCT were collected. The original images were transferred to workstation for image processing. MPR images were acquired. The anatomic relationship between labyrinth segment of facial canal and cochlea was observed in oblique coronal MPR images. The bony septum between labyrinth segment of facial canal and cochlea was assessed as definite defect (Type Ⅰ), doubtful defect (Type Ⅱ) or complete (Type Ⅲ), respectively. Results There were 71 ears (71/220, 32.27%) of Type Ⅰ, diameters of bone fissure ranged from 0.3-1.3 mm (average diameters mm), 86 ears (86/220, 39.09%) of Type Ⅱ and 63 ears (63/220, 28.64%) of Type Ⅲ, with bony septum thickness ranged from 0.3-1.0 mm (average thickness mm). No statistical difference of rates of the above three types was found between different genders, among age groups and between both side of ears (all P>0.05). Conclusion HRCT is a reliable method to show the anatomic relationship between labyrinth segment of facial canal and cochlea. |
