It is our pleasure to announce the 17th Endoscopic Course for Paranasal Sinus and Skull Base Surgery 2021 under the direction of the Swiss Rhinology board in collaboration with the Department of ENT, Head and Neck Surgery Inselspital and the Institute of Anatomy of the University of Bern. The course will strongly emphasize anatomical wholehead dissection. Individual dissection sessions will be framed by lectures and live anatomical demonstration. This will cover the theoretical background, the step-by-step guide through the procedures, and open discussion with the faculty. Feedback by former course participants made us allocate even more time to hands-on.
