数字化技术辅助颅颌面三维正中矢状面确立的研究进展

Digital technology assisted the establishment of craniomaxillofacial midsagittal plane

正中矢状面(midsagittal plane,MSP)是经过人体正中线的矢状平面。MSP作为颅颌面三维结构中最主要的对称面之一,在面部对称性分析及恢复中具有重要意义。目前临床确立正中矢状面的方法存在医师主观因素影响大、标点过程费时费力、标志点组合选择无通用标准等问题,进而也催生了一系列基于数字化技术确立颅颌面MSP的研究,展现了数字化技术在颅颌面MSP确立中的巨大潜力。本文回顾数字化技术辅助确立颅颌面MSP的研究进展,着重对点构法、对称法、深度学习法确立颅颌面MSP的现有研究进行综述,探讨数字化技术对颅颌面MSP建立的进一步优化方案。

The midsagittal plane(MSP),defined as the sagittal plane that intersects the human body by its midline,is one of the most crucial symmetrical planes of the 3D craniomaxillofacial structure,holding huge significance in the analysis and restoration of facial symmetry.In clinic,the commonly-used method for establishing craniomaxillofacial MSPs is subject to such limitations as doctors'subjective factors,the excessive time consumption,and the lack of universal standards for the selection of anatomical landmarks.The aforementioned issues have spawned a series of studies on the establishment of craniomaxillofacial MSPs based on digital technology,indicating the great potential of digital technology in this field.This article systematically reviewed the research progress of digital technology assisted craniomaxillofacial MSP establishment,focusing on the existing research based on landmark-based method,symmetry method and deep learning method,and elaborating the further optimization of craniomaxillofacial MSP establishment by digital technology.
