Chronic Rhinosinusitis is an inflammation in paranasal sinus and nasal cavity that can last up to a minimum of 12 weeks with prevalence 1% to 12% globally. The etiology of chronic rhinosinusitis is usually caused by combination of various factors such as pathogenic organism and obstruction of the sinus tract. The latest study also found imbalance in natural microbiome can cause chronic rhinosinusitis. One of the alternative therapies to help alleviate chronic rhinosinusitis is using probiotic. Probiotic is a living microorganism that, if given in adequate dosage, will provide health benefits for the host by keeping the balance of microbiome or commensal bacteria count in the body.
