Endoscopic Sinus Surgery (ESS) is a minimally invasive procedure used to treat a variety of chronic sinus conditions by restoring normal drainage and ventilation of the sinuses. Using a small, high-definition endoscope inserted through the nostrils, your ENT surgeon can identify and remove blockages without the need for external incisions.
ESS is commonly performed for patients suffering from persistent sinus infections, nasal polyps, blocked sinus passages, or structural abnormalities that have not improved with medication. The procedure helps reduce inflammation, improve airflow, relieve facial pressure, and significantly decrease the frequency of sinus infections.
At Battersea Hospital, our experienced ENT specialists use advanced endoscopic technology and evidence-based techniques to provide effective treatment with minimal discomfort and faster recovery.

ESS is the general term for endoscopic sinus surgery, while Functional Endoscopic Sinus Surgery (FESS) specifically focuses on restoring the natural function and drainage of the sinuses using minimally invasive techniques. Your consultant will recommend the most appropriate approach based on your condition.
No. The procedure is performed entirely through the nostrils using an endoscope, so there are no visible external scars.
Most patients begin noticing improved breathing and reduced congestion as swelling settles during the first few weeks after surgery. Full healing continues over several months.
While ESS can provide long-lasting relief, ongoing management may still be required for conditions such as allergies or chronic inflammatory sinus disease. Your consultant will discuss the best long-term treatment plan for you.
