【摘要】 目的 探讨汶川大地震患震患者颌面部压榨性骨折的MSCT表现特征。方法 回顾性分析85例颌面部地震伤患者的MSCT资料,评价其骨折的解剖分布特点。结果 85例骨折患者中,单一骨受累者(59例)较多骨受累者(26例)常见(P<0.05)。骨折只累及面中部骨者49例(57.6%),只累及下颌骨者24例(28.2%),同时累及两部分者12例(14.2%),面中部骨折最常见(P<0.05)。下颌骨髁突、上颌窦后外壁和前壁、颧弓及眼眶外侧壁等相对易骨折,其发生骨折数分别占所属骨骨折总数的47.1%(24/51)、41.5%(22/53)和37.7%(20/53)、71.9%(23/32)及63.2%(24/38)。结论 单一骨骨折及面中部骨折是地震伤患者颌面部压榨性骨折中最常见的,MSCT及其三维重建图像能优势地显示颌面部骨折情况。更多还原

【Abstract】 Objective To investigate the multi-slice spiral computed tomography(MSCT) features of crush maxillofacial fractures in the massive Wenchuan earthquake.Methods MSCT data of 85 patients with crush maxillofacial fractures caused by earthquake were retrospectively analyzed.The anatomic distribution of fractures was evaluated.Results In 85 patients,single bone fractures(59 patients) were more common than multiple bone fractures(26 patients)(P<0.05).The fractures involved isolated midface,isolated mandible,and both were found in 49 patients(57.6%),24(28.2%),and 12(14.2%),respectively.Midface fractures were most frequent(P<0.05).The fractures of condyle,posterolateral and anterior wall of maxillary sinus,zygomatic arch and lateral orbital wall accounted for 47.1 %(24/51),41.5%(22/53),37.7%(20/53),71.9%(23/32) and 63.2%(24/38) of the total fractures of the corresponding maxillofacial bones.Conclusion Isolated bone fracture and midface factures are the main features of crush maxillofacial fractures resulted from the massive earthquake.MSCT and three-dimensional reconstruction images can demonstrate maxillofacial fractures well.更多还原
