Abstract:
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.
