目的探讨上半规管裂综合征的MSCT表现特点,进一步提高对该病的认识.方法回顾性分析8例经临床和手术诊断为上半规管裂综合征患者的临床和MSCT资料,分析总结其位置、大小等CT表现,尤其是MPR图像特点.结果 8例患者MPR重组的上半规管最大层面图像均显示了上半规管壁的部分骨质缺损,其顶壁均未见气化,其中有6例发生在顶壁的正中部(4例还涉及顶前部),2例发生在顶壁的后部;其缺损的最大径为0.8～4.2mm,中位数为2.4mm.结论高分辨率MSCT扫描结合MPR技术在上半规管裂综合征患者的影像诊断中具有较大的价值.

Objective To better understand the MSCT characteristic of superior semicircular canal dehiscence syndrome (SSCDS). Methods A retrospective study was conducted on 8 patients who were diagnosed with SSCD syndrome in the otology and skull base surgery group of fudan university. All the patients CT features, the conventional axial and coronal images base on high-resolution MSCT and the images displayed the whole superior semicircular canal, which were reconstructed by using the technology of MPR, were reviewed. Results All the images that displayed the whole superior semicircular canal exhibited the dehiscence. Six patients' dehiscences occur in the middle of the roof over the superior semicircular (4 of 6 dehiscences also occur in the front of the roof), 2 patients dehiscences occur in the back of the roof over the superior semicircular. The range of the maximal diameter of the dehiscence was 0.8-4.2 mm, (median value: 2.4 mm). Conclusion The technology of MPR based on the high-resolution MSCT scan is very useful in diagnosis of the SSCDS.
