Richard Wolf GmbH offers a wide range of instruments for functional endoscopic sinus surgery (FESS). This common operating method for the treatment of the paranasal sinuses is state-of-the-art in medicine today. Our high-definition endoscopes and sinuscopes offer extreme luminous intensity and therefore illuminate the entire paranasal sinus.The FESS method combines lower risk and faster recovery compared to open sinus surgery, where access is achieved via the mouth or face. FESS is a more precise and less invasive option of opening up the paranasal sinuses.
