What is Functional Endoscopic Sinus Surgery?
FESS uses a thin endoscope and small instruments through the nostrils to open blocked sinus passages, without any external incisions.
The entire procedure is performed through the nostrils, leaving no visible scars.

The Care Pathway
1. Assessment
CT imaging and nasal endoscopy confirm the extent of sinus disease.
2. Surgery
The procedure is performed under anesthesia using an endoscope through the nostrils.
3. Recovery
Nasal packing, if used, is removed within a few days, with follow-up visits to monitor healing.
4. Long-Term Care
Nasal irrigation and follow-up visits support healing and reduce recurrence.
“Your care team supports you through every stage, from evaluation to recovery and follow-up.”
Expected Benefits and Possible Risks
The primary goal is lasting relief from chronic sinus symptoms. Most patients experience significant improvement in breathing, smell and quality of life.
Every treatment has potential risks. Your care team will discuss your individual risks before treatment.
Recovery & Follow-up
Most patients return to normal activity within one to two weeks, with full healing over several weeks.
Your care plan includes nasal irrigation, follow-up endoscopic checks, and guidance on preventing recurrence.
Careful monitoring, follow-up testing and guidance all play an important role in achieving the best possible outcome.
