Abstract：Successful execution of a surgical treatment necessitates knowledge of the relevant anatomy, physiology, and pathology, as well as the technical specifics of the operation. At this time, the Cranio-maxillo-facial 3D reconstruction can display bone change and relationship with adjacent structure, which is very useful for clinical assistance examination and more favorable and more accurate for establishing surgical operation planning. Since 1996, many people have undergone this technique at the Service of Plastic and Cranio-maxillo-facial surgery in Beijing. They adapted clinical results to four main indications: 1. Congenitally deformity; 2. Trauma or post-traumatic reconstructive Surgery; 3. Cranio-maxillo-facial tumors surgery and 4. Esthetic surgery. The indication of using the 3D EBCT reconstruction technique in surgery with these managments is discussed and some cases of clinic are demonstrated. 　　The industrial computed tomography (ICT) has been developed rapidly on the non-destructive testing fields and its spatial resolution has already reached 5~ 15μm in magnitude. Prof. Chen Weichang have already applied the micro ICT to examine the tissues of rats and obtained the distinct microscopic CT images of tissues and cells. Micro CT images of the pyramidal neurons of the cerebral cortex, and the structure of the hepatic lobules were first reported in ref.[10], results were very exciting，it means that the advanced technologies of ICT can be available to improve the spatial resolution of the medical CT and that the micro CT is feasible. We suggested that the medical micro CT should composed of the following properties: a small diameter focus spot (1~10μm ) of X- ray source, high speed electronic beam scanning (1~10ms per frame), hyper thin tomo section (5~50μmm thick), super computer with vast storage volume, rapid imaging technique of the region of interest (ROI), special μ- CT technique, etc. It is obvious that the micro CT will give a great impact on the clinical medicine and ＂Ｍaking beauty imaging＂in the 21 century.
