摘要
目的探讨颌面部骨折合并颅颈交界区损伤的影像学特点及多层螺旋CT诊断。方法收集10例颌面部外伤合并颅颈交界区损伤的螺旋CT重建扫描资料,比较常用影像学检查手段的诊断价值。结果上、下颌骨双骨折并颧弓骨折者5例,下颌骨骨折5例。其中3例合并颞颌关节脱位,3例合并有轻、中度颅脑损伤。合并颅颈交界区损伤有:枕颈脱位2例,枕骨髁撕脱骨折2例,寰枢椎旋转性半脱位6例。结论颌面部外伤骨折合并上颈椎损伤多为韧带型损伤,影像学特点为小片的撕脱性骨折及枕颈半脱位、寰枢椎旋转性半脱位;多层螺旋CT重建技术是诊断本病的最佳方式;提高对本病的警惕,重视颅颈交界区解剖标志间关系的画线测量是防止漏诊的关键。
Objective To explore imaging manifestations and diagnostic value of helical CT in maxillofacial fractures associated with craniocervical junction injury. Methods Helical CT findings of ten cases with maxillofaeial fractures involving the craniocervical junction injury were retrospectively analyzed and compared with other imaging techniques. Results There were five cases with both fractures of the maxilla and mandible combined with zygomatic arch fractures, three with mandible fractures combined with dislocation of temporomandibular joint and three with mandible fractures combined with slight and moderate craniocerebral injuries. The combined craniocervical junction injuries included atlantoaxial rotary dislocation in six cases, occipital condyle avulsion fracture in two and occipitocervical subluxation in two. Conclusions Maxillofacial fractures combined with the occipitocervical junction injuries are usually ligament injuries, with radiologic characteristics of avulsion fracture, occipitocervical subluxation and atlantoaxial rotary dislocation. Helical CT is a satisfactory mode for diagnosis of such fractures. More attention should be paid to mark of anatomical relation of craniocervical junction to avoid missed diagnosis.
