[The application of 3D simulationtemporal-bone-system for temporal bone anatomy training].

Objective

The aim of this study is to investigate the application of 3D simulation temporal-bone-system for temporal bone anatomy training.Method:3D simulation temporal-bone-system in the anatomy workshop was introduced in Beijing Children's Hospital from 2014 to 2015.Each participant was trained by cadaver dissection and 3D simulation temporal-bone-anatomy,and they also completed the questionnaires and evaluated the procedure.Then the difference was analyzed.Result:①In stage of mastoid outline,the damage of structure in 3D systemis higher than that in cadaver dissection(33.3%>22.2%),but there were no significant difference between them in the proportion of exposure.On the opening of attic,facial recess,facial nerve,the damage and the proportion of the non-exposed of cadaver dissection is higher.②There were no significant difference between them in the anatomical structures,levels of pollution,taste,cost and reproducibility(P>0.05),but in the aspect of time,relevance of CT with temporal bone,the similarity,and the force feedback,they had significant differences(P<0.01).

Conclusion

3D simulation temporal-bone-system had better training effect in specialized otolaryngologist.It not only to help clinicians better understanding the temporal bone and surrounding structures,but also to emphasize the knowledge of the anatomy in temporal bone.
