Virtual reality in otolaryngology residency training: essential or "nice to have"?

In virtual reality (VR), complex objects or situations can be simulated for teaching purposes, e.g. an anatomical site or a surgical technique. However, the realization of new VR projects is associated with a high intellectual as well as financial effort - from conception to programming to equipment procurement. Does it still make sense to invest in VR? With this question in mind, we investigated the subjective and objective benefits of a VR model of the middle ear compared with conventional plastic models in otolaryngology residency training.

Residents and specialists at the ENT University Hospitals of Freiburg and Heidelberg were randomly divided into two groups. One group received the conventional plastic model of the middle ear, while the other used the VR model. Subsequently, both groups answered the same questions about middle ear anatomy. In addition, a before/after comparison was performed in the VR group. Finally, we asked the participants for a subjective assessment about benefits of VR compared with conventional models.

The VR model showed a very positive response, with 85% of participants viewing VR as superior to conventional models and 100% agreeing that VR is a useful tool in teaching complex anatomy. Objective evaluation showed significant improvement in knowledge through VR use (before/after comparison). In direct comparison to conventional plastic models, no significant advantage of the VR model was shown.

In conclusion, the use of VR in otolaryngology residency training is worthwhile. It can make the learning process more intuitive and sustainable. In addition, VR offers extensive possibilities for further development - in contrast to the plastic model.
