Chronic rhinosinusitis, also called chronic sinusitis, is a very common life-long disease affecting over 5% of the Canadian population. Its symptoms, including daily facial pain and headache, an inability to breath through the nose and complete smell loss, regularly impair one's ability to work and to enjoy and participate in daily activities. The annual cost of chronic sinusitis to Canada is estimated at $1.3 billion while the government pays an estimated $860 million yearly for chronic sinusitis treatment. Chronic sinusitis with polyps, the most common type of chronic sinusitis, is usually treated with a combination of medications and surgery. Until now, surgical treatment has only been performed in the operating room, at a cost of about $3500 per procedure. But, recent studies have shown that a new procedure, "in-clinic polyp removal", can provide an improvement in patient symptoms to levels equal to those for sinus surgery performed in a hospital operating room. Moreover, in clinic polyp removal has additional advantages including a shorter procedure recovery time, a significantly lower cost to the health care system (about one-tenth the cost or $450), and a shorter wait time for treatment. With the proposed pragmatic trial, the investigators will determine whether the in clinic polyp removal procedure is as good as sinus surgery in the operating room at controlling patient symptoms of chronic sinusitis. The investigators will also determine the cost and health-benefits for a patient, the healthcare system and for society of in clinic polyp removal in comparison to sinus surgery done in a hospital operating room. The investigators will then know if this new treatment, in clinic polyp removal, can replace sinus surgery as the standard of care for these patients.
