Abstract：BACKGROUND:The design and communication of cosmetic operation is more refined than that of traumatic operation. Thus, more accurate data should be acquired and more precise three-dimensional models should be reconstructed. <br> OBJECTIVE:To investigate the prospect of 3D laser scanner and matched graphics-processing software which acquire and analyze facial morphological data in the modern cosmetic surgery. <br> METHODS: We obtained the point clouds of the facial surface in two cases of facial soft tissue defects or dissatisfied facial appearance using a hand-held laser scanner to reconstruct a visualized facial model, which was used for measurement of facial profile, simulation of cosmetic operation and evaluation of the therapeutic effects. <br> RESULTS AND CONCLUSION:We simulated and designed upon the NURBS model before the operation primarily. Then the three-dimensional comparison was done between the simulate model and the postoperative model. Deviation analysis showed that the ratio of variation degree of the two models within 1 mm was more than 80%. It enables the rapid three-dimensional reconstruction of the facial surface by the combination of reverse engineering and laser scanning, thus providing accurate three-dimensional data for cosmetic design and quantitative evaluation of therapeutic effects in cosmetic surgery.
