Abstract: Objective To investigate the application of virtual and 3D printing model in clinical standardized training of otorhinolaryngology residents. Methods Forty-two rhinologists residents in standardized training (from January 2017 to September 2021) were randomly divided into the experimental group and the control group. The experimental group were trained by virtual and 3D printing model, while adopting traditional training methods in the control group. Then the questionnaire and the image reading of nasal sinus CT were used to evaluate the training effect. The chi-square test was used for comparison among groups of counting data, and independent sample t-test was used for measurement data between groups. Results The questionnaire showed that the scores of the experimental group and the control group were (18.43±1.40) and (12.43±1.21) respectively. In the comprehensive evaluation of the image reading effect, the scores of the experimental group and control group were (93.52±2.62) and (81.43±2.27). These differences were all statistically significant (all P<0.001). Conclusions The training method of virtual modeling combined with 3D printing model has been recognized by the residents, which would greatly improve the understanding of anatomy knowledge of nasal cavity and paranasal sinuses.
