目的采用多层螺旋CT (MSCT)研究眼眶滑车的解剖特点及临床意义.方法对2012年11月至2013年8月在奉化市人民医院眼科就诊的413例眼眶滑车根据有无钙化分组进行观察,127例行MPR与VR.结果滑车均双侧对称,位置固定,附着于眶内侧壁前上方,与上斜肌反折肌腱连成一体.无钙化组325例,呈软组织密度;钙化组88例,占21.31％ (88/413),单侧钙化39例,双侧49例,双侧钙化大小形状可不一致.结论 MSCT显示眼眶滑车的解剖特点极具特征,对滑车钙化的鉴别诊断具有重要的临床意义.

Objective To observe the anatomical characteristics and clinical significance of orbital trochlea using multi-slice spiral CT (MSCT).Methods In this research,413 patients with MST CT routine inspection were divided into two groups according to the presence or absence of calcification of the orbital trochlea,in which 127 cases underwent MPR and VR.Results All patients shown bilateral symmetry orbital trochlea,fixed position,attached to the top of the front medial orbital wall,with reflexed superior oblique tendon piece.The 325 cases of no calcification group shown soft tissue density;the 88 cases of calcification group that accounted for 21.31％ of patients overall,unilateral calcification shown in 39 cases,bilateral calcification shown in 49 cases calcification size and shape could be inconsistent with bilateral.Conclusions MSCT can clearly show the anatomical features of the orbital pulley,this is important for the differential diagnosis of calcification tackle.
