Introduction: MeCumLMU (Munich medical school curriculum) provides a variety of bedside teaching modules even in the OR. Functional endoscopic sinus surgery (FESS) is suited best for visualization purposes in student teaching. In combination with image guided surgery the CT-scans can be demonstrated in real time with the endoscopic view in order to get a better spatial orientation for the students. To evaluate the benefit for students of this technology was the key question of this clinical trial.

Materials and methods: 54 medical students had to fulfil a questionnaire about the usage of the information of the navigation system after 20 navigated FESS procedures. Students were teached and asked about the anatomical structures, pathologies and the surgical approaches pre- and intraoperatively. Students should point out the anatomical landmarks on the screen of the navigation system during and after the surgery.

Results: 50 evaluation questionnaires could be included. 68% of the students (n=34) admitted that the navigation technology was completely new for them. 88% (n=44) could identify all sinuses on the screen. All students (100%) were fascinated by the technology and visualization possibilities of the navigation system. All students stated that the additional information of the navigation system helped for a better anatomical understanding and spatial orientation. 98% of the students indicated that image guided surgery helped the surgeon for a better outcome.

Discussion: Medical students benefit from the additional information of a navigation system in the bedside teaching situation after a profound explanation of the system itself and a thoroughful learning of the difficult anatomy of the paranasal sinuses. Without explanation and anatomical knowledge the spatial orientation is not improved by a navigation system in the OR bedside teaching.
