摘要:

目的 对不同程度单侧唇裂患者的磁共振成像(MRI)影像数据进行三维重建,分析动静态下多组鼻唇部肌肉解剖形态及变化规律。 方法 纳入1例正常人及4例成年单侧唇裂患者,分别在静态(上下唇自然闭合)和动态(嘟嘴、咧嘴)下行MRI检查,使用3D Slicer软件对影像数据进行三维重建,绘制鼻唇肌肉的解剖形态。测量3种动作下裂隙侧和非裂隙侧提上唇肌、颧小肌、颧大肌的交界点(肌肉汇入口轮匝肌的位置)到正中矢状面、肌肉起始点到交界点、动静态交界点之间的距离及动静态交界点连线与水平面的角度,并做比值计算。 结果 动静态下4例单侧唇裂患者的肌肉交界点到正中矢状面裂隙侧与非裂隙侧的距离比值均大于1,而肌肉起始点到交界点的该项距离比值均小于1。静态下同名肌肉的这两项距离比值均随唇裂程度加重呈梯度增加,且静态下同一患者中颧小肌的这两项距离比值更突出。3组肌肉从静态到动态的交界点连线与水平面所成角度,裂隙侧与非裂隙侧的比值均大于1。 结论 单侧唇裂患者两侧肌肉插入口轮匝肌的位点对称性、直线距离均与肌肉类型、唇裂类型相关;裂隙侧肌肉收缩角度大于非裂隙侧。

Abstract:

Objective This study aims to obtain a three-dimensional reconstruction model based on magnetic resonance imaging (MRI) data of patients with different degrees of unilateral cleft lip and analyze the anatomy and changes in multiple groups of nasolabial muscles under dynamic and static conditions. Methods One normal person and four adult patients with unilateral cleft lip were included, and MRI was performed under static (upper and lower lips closed naturally) and dynamic (pout and grin) conditions. 3D Slicer software was used to reconstruct the model and draw the anatomic morphology of nasolabial muscles. The distance between the junction (where the muscle merges into the orbicularis oris) of the levator muscle, zygomaticminor muscle, and zygomatic major muscle to the median sagittal plane, the starting point to the junction point, the dynamic and static junction points, and the angle between the connection of dynamic and static junctions and the horizontal plane were measured under three kinds of movements, and the ratio was calculated. Results In all patients, under dynamic and static conditions, the distance from the muscle junction to the median sagittal plane, their ratios of the cleft side to the non-cleft side were all greater than 1. While the ratios of the distance from the starting point of the muscle to the junction point were less than 1. At static conditions, the two ratios of the same muscle increased gradiently with the severity of the cleft, and the ratio of the zygomatic minor muscle was prominent in the same patient. The ratio of the cleft side to the non-cleft side was greater than 1, and the value for comparison was the angle of the line from the static to the dynamic junction and the horizontal plane. Conclusion The symmetry of the insertion site of the orbicularis oris and the linear distance of both sides of the muscle are related to muscle and cleft types. The angle of muscle contraction on the cleft side is greater than that on the non-cleft side.
