Abstract: PURPOSE: To explore the application value of virtual endoscopy simulation system in clinical teaching of trigeminal neuralgia. METHODS: The clinical teaching content of trigeminal neuralgia was presented using Stlview software based on virtual endoscopy. Twenty-four interns were enrolled from Shanghai Jiao Tong University College of Stomatology, 12 interns were assigned into the virtual endoscopic teaching group and the other 12 interns into the traditional teaching group. The age and gender of the two groups were matched. The ability to understand the knowledge of the teaching was evaluated through theoretical assessment and comprehensive ability assessment, and the results were also evaluated through self-designed questionnaires survey. SPSS 23.0 software was used to analyze the data. RESULTS: Compared with the traditional teaching group, the interns of the virtual endoscopy teaching group had no significant difference in the score of theoretical knowledge assessment (P=0.289), but the score of virtual endoscopic teaching group was significantly greater than the traditional teaching group in the comprehensive ability assessment(P=0.039), and the virtual endoscopy teaching group was evaluated by questionnaire to have significant advantages in three-dimensional sense of space, learning initiative, teaching interaction and learning interest. CONCLUSIONS: Virtual endoscopy has a broad application prospect in clinical teaching of trigeminal neuralgia, which has a complex structure and strict operation, and can improve the quality of clinical teaching.
