摘　　要：目的:分析Pierre-Robin综合征(PRS)的影像学表现,探讨PRS的影像分型。方法:对52例经临床诊断的Pierre-Robin综合征患儿全部行MSCT容积扫描,通过工作站对容积数据进行多平面重建(MPR)、容积再现(VR)等后处理重建,分析影像学表现并测量及分型。结果:影像学表现:下颌骨短小且下颌后缩52例,下颌骨内旋28例,腭裂49例,舌根后坠47例,气道狭窄38例;测量:0.78±0.12;分型:I型5例,II型36例,III型11例。结论:PRS影像学的表现已经成为诊断PRS的客观依据,而影像分型将为临床提供更多支持。Purpose： To analyze the imaging features of Pierre Robin syndrome （PRS） and discuss the imaging types of PRS. Methods： Fifty-two patients with clinical diagnosed Pierre Robin syndrome were all underwent MSCT volume scanning. The volume data was transferred to the workstation and the image reconstruction including multi-planar reconstruction （MPR） and volume rending （VR） were performed. The imaging findings were analyzed, measured and classified. Results： Of these 52 PRS patients, the major imaging features were short mandible and mandibular retrusion （52 cases）, mandibular rotation （28 cases）, cleft palate （49 cases）, falling back of the tongue root （47 cases）, and airway narrowing （38 cases）; The measuring result was 0.78±0.12; The imaging features were classified into 3 types： 5 cases were belonged to type I, 36 cases were belonged to type II, and 11 cases were belonged to type III. Conclusion： Imaging features of PRS have become the objective evidence for diagnosis of PRS and imaging classification will provide more support for clinical practice.
