Functional Endoscopic Sinus Surgery (FESS) is a minimally invasive procedure used to treat chronic sinus problems that have not responded to medication or other non-surgical treatments. Using a thin endoscope inserted through the nostrils, your surgeon can carefully remove blockages, improve drainage, and restore normal airflow without making any external incisions.
FESS is commonly recommended for patients experiencing recurrent sinus infections, chronic sinusitis, nasal polyps, or blocked sinus passages that significantly affect breathing and quality of life. By improving sinus function, the procedure can reduce symptoms such as facial pressure, congestion, headaches, and repeated infections.
At Battersea Hospital, our experienced ENT specialists use advanced endoscopic techniques to deliver precise treatment with minimal disruption to surrounding tissues, promoting faster recovery and long-lasting symptom relief.

FESS is commonly used to treat chronic sinusitis, recurrent sinus infections, nasal polyps, blocked sinus passages, and certain structural problems that affect sinus drainage.
No. The procedure is performed entirely through the nostrils using an endoscope, so there are no visible external incisions or scars.
Most patients return to work within one week, although complete healing inside the nose continues over several weeks. Your surgeon will provide detailed aftercare instructions.
Many patients experience significant improvements in nasal breathing, reduced congestion, fewer sinus infections, and an overall improvement in quality of life once healing is complete.
