Abstract: Objective To assess the application of 64-row volumetric CT three dimensional image formation to shape the titanium mesh for the skull neoplasty. Methods 40 cases were divided into the shaping before operation group (21 cases), in which the titanium meshes were shaped with the data from 64-row volumetric CT skull three dimensional image formation before operation; and the shaping during operation group (19 cases), in which the titanium meshes were shaped approximately before and exactly during operation. The time of shaping, anaesthesia and the whole operating were compared, and the qualities of the skull plasty were assessed. Results All the skull repaired satisfactorily. The time of shaping, anaesthesia and the whole operating was shorter in shaping before operation group than in shaping during operation group (P<0.05). No complication was observed. Conclusion Application of 64-row volumetric CT three dimensional image formation in the skull neoplasty may reduce the surgery time and risk.
