Abstract:
Objective:This study is to manufacture the templates for costal cartilage carving, by digital simulation and three-dimensional printing technology, to realize the individualization of rhinoplasty.
Methods:Preoperative simulated images and 6-month postoperative images, of 10 patients were included in this study. The simulation was produced using Geomagic Studio 2013 and 3-matic Research 9.0 software, according to patients′requirements. The templates for costal cartilage carving during the operation, were designed, measured and three-dimensional printed. Statistical analyses were performed using paired t-test.
Results:The dorsal length in preoperative simulation was significantly shortened, compared with postoperative [(4.73±0.11) cm vs. (4.88±0.16) cm, t=-0.465, P=0.001). The nasal tip projection in preoperative simulation is parallel with postoperative[(2.66±0.10) cm vs. (2.66±0.11) cm, t=0.068, P=0.947). The nasolabial angle in preoperative simulation is slightly greater than postoperative, yet failed to reach statistical significance (95.3±3.1 degrees vs. 94.3±3.0 degrees, t=1.936, P=0.085). Most of the patients were satisfied with both the preoperative simulation and the surgical outcomes.
Conclusions:With the assistance of digital simulation and three-dimensional printing technology, the expectation of rhinoplasty patients can be visualized, which is helpful to minimize the difference between surgical outcomes and the patient′s anticipation. Therefore, the digital simulation and three-dimensional printing technology should be considered, to provide individually surgical plan for this group of patients.
