Abstract Objective To explore the effect of using 3D printing model in endoscopic endonasal surgical practice.Methods The surgical training model was made using 3D printing technology.In January 2018,12 postgraduates and low-grade resident doctors with no experiences of endoscopic endonasal surgery were recruited to participate in the surgical training used the 3D printing model as tools.Drilling,curetting,biting and aspirating under endoscope were practiced repeatedly used the eggs fixed on the 3D printing model as objects.The training results and the subjective feelings after training for each practitioner were recorded.Results As the number of training was increased,the speed and quality of the endoscopic operation for these practitioners were increased gradually.Compared with the first training,the results of the last training(the fifth time)of practitioners,including the time spent in drilling the eggshell([3.93±0.77])min vs.[2.87±0.44]min)(P<0.001),the probability of shell membrane rupture during drilling the eggshell(11/12 vs.4/12)(P=0.009),the probability of shell membrane rupture during curetting and biting the eggshell(12/12 vs.6/12)(P=0.014),the probability of yolk membrane rupture during aspirating the albumen(7/12 vs.1/12)(P=0.027),and the surgical practice score([2.17±0.72]points vs.[4.75±0.87]points)(P<0.001),were improved significantly.Moreover,all of the participants subjectively stated that they could obtain benefits from the practice and willing to train with 3D printed models.Conclusion The endoscopic endonasal surgical practice using 3D printed model as tools can effectively improve the endoscopic surgical operation skills of practitioners and may contribute to stimulate the enthusiasm of practitioners.
