Chronic rhinosinusitis: a microbiome in dysbiosis and the search for alternative treatment options

Abstract

Chronic rhinosinusitis (CRS) is a common chronic disease. While CRS is a multifactorial disease, many cases involve an imbalance in the sinus bacterial microbiome. This article reviews the composition of the healthy human sinus microbiome compared to the microbiome of CRS patients. Issues with current treatment options, particularly antibiotics, are discussed. Insights into the future of CRS treatment are also explored, principally with regards to probiotics.
