Endoscopic sinus surgery is a procedure where someone is put under with a general anaesthetic and with multiple different types of instruments, the surgeon will go into the nose and the aim is to open up one or more of the sinus cavities, depending on the extent of disease

It's the surgeon’s job is to go in and open up those doorways in order to allow the sinuses to drain as well as help optimize the delivery of medical or topical treatments to the sinuses, such as steroids, anti-inflammatory sprays or antibiotics.

Patients will also have diagnostic tests done such as endoscopy or CT scans, which will further confirm that they have blockages and infection that lead to chronic symptoms.

Surgeons will typically try and get the medical reasons a person is experiencing chronic rhinosinusitis in control before surgery, such as allergy symptoms, exposure to molds, inflammation and the presence of polyps

Approximately 80% of people who get sinus surgery do very well with a combination of surgery plus topical medical therapy.
