Abstract: Objective To establish a measurement system,which can provide the 3D information immediately and accurately for nose implant.Methods Twenty patients were selected in random;and the figure model was established by 3D laser passing and CT scan.The two models were opened in the photo station at the same time;and then fitting was done according to the facial landmark points.Results By fitting,the precise 3D information of patient\'s faces.Conclusion Combining the information from laser passing and CT scan,the measurement system for designing digital nose implant could be get accurately and quickly.It is more valuable on the digital design of rhinoplasty.

Key words: 3D laser passing, CT scan, Rhinoplasty, Mould
