Abstract: Objective To explore SECTRA 3D real-time reconstruction of virtual simulation technology in the anatomy teaching of otolaryngology. Method Eighty medical students who have received traditional class teaching of otolaryngology anatomy joined the SECTRA 3D real-time reconstruction class to study the major anatomic knowledge of otolaryngology. Questionnaires and exams were provided for them before and after the SECTRA 3D real-time reconstruction class.Results The test scores were 79.19±10.39 before 3D class and 87.69±10.25 after 3D class. After teaching, the scores improved significantly.Conclusion Application of SECTRA real-time reconstruction of 3D virtual simulation technology in otolaryngology anatomy teaching, can help medical students to master the anatomical knowledge better than the traditional class teaching and can stimulate their interests to learn otolaryngology anatomy.
