Abstract
ii ABSTRACT Introduction: The aim of this study was to determine whether the use of 3D-HD-endoscopy would lead to faster and more efficient performance on endoscopic tasks in the sinonasal area, compared to the use of 2D-HD-endoscopy. Methods: Thirty endoscopically naïve subjects were randomly divided into two groups. Prior experience with endoscopic procedures, other possible relevant experience and demographic data were collected using questionnaires. All subjects carried out five endoscopic tasks in the nose and paranasal sinuses of a human body, during two consecutive rounds,. Subjects of one group started using 2D-endoscopy and switched to using 3D-endoscopy before starting the second round. The reversed order was used by the other group. Time to complete each part of a task, errors made, distance travelled, average velocity and subjective experience were registered. Statistical tests for paired data were used to compare results between both endoscopes and between the results of both rounds. Results: No statistically significant difference was found in time score, errors made, distance travelled or average velocity between the use of 2D- and the use of 3D-endoscopy. Depth perception and image quality of the 3D-endoscope were rated significantly better. The use of 3D-endoscopy in the first round resulted in significantly poorer results compared to the use of 2D-endoscopy. In contrast, the results using 3D-endoscopy in the second round were superior to both the results using 3D-endoscopy in the first round and the results using 2D-endoscopy in either the first or second round. Statistically significant, positive correlations were found between endoscopic experience and the ability to locate anatomical structures and targets in the nose faster. Videogame-experience showed significant positive correlation with better performance during the second round of tasks. Discussion: The use of 3D-endoscopy did not lead to significantly better results compared to the use of 2D-endoscopy. The superior results in the second round using 3D-endoscopy were neutralized by the poor results during the first round. This could be explained by the limitations of 3D-endoscopy when used in narrow spaces, together with the limited experience of the subjects in this study. Furthermore the type of endoscope used during the first round seemed to be of influence on the size and direction of the learning effect. As did videogame-experience seem to reinforce the learning effect, while prior knowledge of the anatomy of the sinonasal area led to faster identification of anatomical landmarks and targets in the nose. Conclusion: Based on the results of this study, the use of 3D-endoscopy did not lead to significantly better performance on various endoscopic tasks compared to the use of 2D-endoscopy, when used by subjects with little to non prior experience in endoscopic procedures, in the narrow area of the nose and paranasal sinuses.
