📖About Functional Endoscopic Sinus Surgery
Functional endoscopic sinus surgery (FESS) is a minimally invasive procedure that uses a nasal endoscope to open blocked sinus passages and remove diseased tissue, polyps, or obstructions causing chronic sinusitis. Unlike older external sinus surgery approaches, FESS works entirely through the nostrils without any external incisions, guided by the endoscope's camera view. It aims to restore normal drainage and ventilation of the sinuses, relieving symptoms such as facial pain, congestion, and recurrent infections. It is typically considered after medical treatment for chronic sinusitis has failed.

🔬How the Treatment is Performed
- 1Under general or local anaesthesia, the surgeon inserts a rigid endoscope through the nostril to visualise the sinus openings, then uses specialised micro-instruments to remove polyps, diseased tissue, or bone obstructing normal sinus drainage pathways. The extent of surgery depends on which sinuses are affected, ranging from opening a single sinus to a more extensive procedure addressing multiple sinus groups. Nasal packing may be placed temporarily to control bleeding.
