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.
