Abstract:
BACKGROUND:Recently, scholars al over the world have made numerous studies on three-dimensional visualization model of reconstructing maxil ofacial bone tissue, skin, and muscle in the ordinary PC. However, few studies concerned the three-dimensional visualization model of constructing maxil ofacial bone tissue, skin, muscle and blood vessels. OBJECTIVE:To establish a three-dimensional visualization model of the complete maxil ofacial region using an ordinary PC based on spiral CT, MRI data, and three-dimensional reconstruction software. METHODS:One healthy male adult was chosen as the object in this study. CT and MRI were performed respectively to acquire the DICOM standardized image of the sample. Al CT and MRI images were imported to Mimics to construct three-dimensional visualization models of the bones in the maxil ofacial region, some masseter muscles, trigeminal cistern, internal carotid artery and internal jugular vein. Three-dimensional model of the bones in the maxil ofacial region was chosen as the reference. Models of muscles, blood vessels and trigeminal cistern established by MRI images were imported, and registration in space of three-dimensional model was performed. At last, three-dimensional visualization model of the complete maxil ofacial region was acquired. RESULTS AND CONCLUSION:The integrated three-dimensional models of the bones, muscles, skin, trigeminal cistern and blood vessels in the maxil ofacial region established accurately reflected the complex anatomic structure of maxil ofacial region, provided reliable anatomic data for clinical diagnosis and laid a good foundation for sham operations in the future.
