Objective To achieve three-dimensional visualization and quantitative analyses of craniomaxillofacial structures. Methods A versatile software package written in visual C ++ language has been developed,which consist of several functional modules including three-dimensional reconstruction, 3-D measurement, and electronic anatomy etc. By means of the comprehensive software package, the polygon-oriented surface rendering algorithm was adopted to implement 3-D volume digital data of craniofacial skeletal and soft-tissue structures. Results The 3-D stereo models of craniofacial soft-tissue and osseous-tissue were retrieved from a series of 2-D CT slices. With rotating of these 3-D visual models, the anatomic structures could be observed and analyzed from different viewpoints. The arbitrary cross-section and partial structure could be displayed and manipulated on the 3-D visual models. Conclusions The aforementioned microcomputer software system provides novel technique of qualitative and quantitative diagnoses, and analyses for craniofacial surgery. The electronic anatomy of craniofacial morphology was realized, which provide useful methods and stereoscopic models for researches of anatomy, anthropology, medical aesthetics, as well as medical education.
