Study Summary

Chronic sinusitis (CRS) is a common inflammatory condition of the sinuses that affects up to 2.5% of the Canadian population, and is thought to be caused by bacterial infection, resistant biofilms, chronic inflammation and possibly an unhealthy population of sinus microbes (or microbiota). Symptoms include nasal obstruction and discharge, facial pain, loss of smell and sleep disturbance, which all strongly impact quality of life. CRS treatment involves nasal or oral steroids, repeated rounds of antibiotic, and sinus surgery. Despite maximal treatment, some recalcitrant patients suffer with CRS for years. The lack of new, effective therapies to treat CRS leads the investigators to test whether a SinoNasal Microbiota Transfer (SNMT) could trigger CRS recovery. SNMT is defined as the endoscopic transfer of a healthy sinus microbiota from a fully screened donor's sinus to a CRS patient's sinus(es). Similar to a fecal transplant used to treat Clostridioides difficile diarrhea, the sinonasal microbiota transfer may eliminate sinus pathogens and restore the sinus microbiota to a healthy state. SNMT will be combined with a one-time, high volume, high pressure "sinus power wash" pre-treatment to temporarily clear the way for the donor microbiota to establish itself. The investigators will conduct a proof-of-principle, randomized, double-blind, placebo-controlled trial of 80 subjects to test whether a sinus power wash plus SNMT improves clinical outcomes in CRS patients.
