Endoscopic sinus surgery (ESS) is a surgical procedure that is used to treat chronic sinusitis, a condition in which the sinuses become inflamed and swollen for a prolonged period of time. ESS is performed using an endoscope, a thin, rigid endoscope with a camera and light at the end that allows the surgeon to see inside the sinuses and remove blockages or damaged tissue.

During ESS, the surgeon makes small incisions in the nasal cavity and inserts the endoscope to visualize the sinuses. Specialized instruments are then used to remove any diseased tissue or bone, clear blockages, and widen the sinus openings to improve drainage and airflow.

ESS is typically performed under general anesthesia and is usually an outpatient procedure, which means the patient can go home the same day. Recovery time varies depending on the extent of the surgery and the individual’s overall health, but most people are able to return to work or school within a week or two.

ESS is generally considered safe and effective, and most people experience significant improvement in their sinus symptoms after the procedure. However, as with any surgical procedure, there are risks involved, such as bleeding, infection, and injury to surrounding structures. It’s important to discuss the risks and benefits of ESS with your healthcare provider to determine if it’s the right option for you.
