摘要
目的探索应用5.0 T磁共振成像(MRI)重建面部表情肌的可行性。方法获取2024年2月1日于复旦大学类脑智能科学与技术研究院自愿接受5.0 T MRI头颅扫描的32岁健康成年男性志愿者影像资料, 利用3D Slicer软件对表情肌逐个进行区域划分和三维重建, 并与1具成年男性头颅标本(复旦大学附属眼耳鼻喉科医院解剖室提供)的面部表情肌精细解剖结果进行对比。研究对象均排除面部畸形、外伤以及累及肌肉的全身系统性疾病。结果 5.0 T MRI可以展示面部各表情肌的位置、大小及毗邻关系:三个方位中, 冠状位对于面部表情肌的总体展示最具优势, 薄层轴位对于截面的连续性和三维定位非常有帮助, 而矢状位对于表情肌的层次、起止点定位更具优势;眼轮匝肌、皱眉肌、提上唇肌、提上唇鼻翼肌、提口角肌、口轮匝肌、颏肌、笑肌、颧大肌及颧小肌、降下唇肌、降眉间肌、降眉肌、降口角肌、鼻肌的三维重建结果与头颅标本的面部表情肌实际解剖有良好的对应关系。结论 5.0 T MRI能够清晰显示面部表情肌, 对整形外科教学及虚拟手术设计具有良好价值。
Objective:To explore the feasibility and reliability of reconstructing mimetic muscles by using 5.0 T magnetic resonance imaging(MRI)technology.Methods:Imaging data were obtained from a 32-year-old healthy male volunteer who voluntarily underwent a 5.0 T MRI head scan at Institute of Brain-like Intelligence Science and Technology of Fudan University on February 1,2024.The mimetic muscles were segmented and reconstructed in three dimensions using 3D Slicer software.The result were compared with the detailed anatomical findings of the mimetic muscles from a cadaveric male head specimen(provided by the Anatomy Department of Eye Ear Nose&Throat Hospital of Fudan University).The research subjects did not have facial deformities,traumas,or systemic diseases affecting muscle integrity.Results:The 5.0 T MRI clearly demonstrated the location,size,and anatomical relationships of the mimetic muscles.Among the three planes,the coronal plane provided the best overall view of the facial expression muscles,while thin-layer axial images were beneficial for ensuring continuity and accurating three-dimensional localization.The sagittal plane offered superior information on the layers and attachment points of the muscles.The three-dimensional reconstructions of muscles such as the orbicularis oculi,corrugator supercilii,levator labii superioris,levator labii superioris alaeque nasi,levator anguli oris,orbicularis oris,mentalis,risorius,zygomaticus major and minor,depressor labii inferioris,procerus,depressor supercilii,depressor anguli oris,and nasalis showed good correspondence with the actual anatomical findings of the mimetic muscles in the head specimen.Conclusion:High-field strength MRI can clearly display facial expression muscles,offering potential value for plastic surgery education and virtual surgical planning.
