Endoscopic Sinus Surgery: Endoscopic sinus surgery is the intranasal removal of diseased tissue from the nasal cavities and sinuses under endoscopic guidance, while the surgeon views the surgical field on a monitor. Great care is taken to work with the confines of the sinus cavities, while maintaining the integrity of the outside boundaries, most notably the inside wall of the eye socket and the base of skull.
Image guidance systems may be employed to assist the surgeon in reaching the areas of disease while avoiding violation of the accepted boundaries of dissection. Endoscopic sinus surgery allows the surgeon to remove diseased tissue such as nasal polyps in a neat and complete manner, while establishing appropriate drainage and ventilation between the sinuses and nasal cavities. Postoperative bloody spotting occurs for the first day or two, and postoperative pain is usually mild to moderate.
Over the past several years, minimally invasive surgical techniques ("Balloon Sinuplasty") have been developed for opening blocked sinus drainage passages without the removal of bone or tissue in well-selected patients. These techniques can be performed in the Operating Room or office (again, in well-selected patients) with topical and local anesthesia.
Another recent developement encorporated into our practice is the use of biodegradable steroid-eluting sinus stents into (the ethmoid) sinus cavities during sinus surgery. These temporary implants serve to both hold the cavities open and prevent scarring and early polyp formation, allowing for a healthy, more normal sinus lining to form during the early postoperative period.
