Open sinus procedures often require facial incisions (cuts made on the face) resulting in visible scars and the need for nasal packing. With FESS, your surgeon can have a better view within your nose and sinuses so surgery is almost always done completely through the nostrils, leaving no visible signs and less scarring.
This means that you will experience less post-operative pain and bleedings. FESS also reduces the need for nasal packing, allowing you to breathe normally through your nose with minimal discomfort.
