Rhinology research, endonasal sinus and skull base surgery

Endoscopic endonasal surgery (EES) is the therapy of choice to access pathology of the paranasal sinuses and/or anterior skull base. New technical developments in surgery are associated with an adjustment period in which surgeons acquire new surgical skills and gain experience.
For computed assisted surgery an optical infrared or an electromagnetic tracking system can be used. It is important to investigate the accuracy of these systems in a clinical setting and factors that influence accuracy.
A recent technical development in EES is the clinical use of a high-definition (HD) endoscope that provides stereoscopic, three-dimensional (3D) visualization of the surgical field. Today it is not clear what impact 3D endoscopy has on surgical efficiency, movement accuracy or the learning curve of (novice) surgeons.
