Sinusitis affects 1 out of every 7 adults in the United States, with more than 30 million individuals diagnosed each year. Sinusitis is more common from early fall to early spring. Rhinosinusitis affects an estimated 35 million people per year in the United States and accounts for close to 16 million office visits per year. [1]

According to the National Ambulatory Medical Care Survey (NAMCS), approximately 14% of adults report having an episode of rhinosinusitis each year, and it is the fifth most common diagnosis for which antibiotics are prescribed, accounting for 0.4% of ambulatory diagnoses. [24]
