Nasal polyps are known to mankind since ancient times. However, to this day, the polypoid vegetation processes remain insufficiently studied, and the problem of polypous rhinosinusitis is widespread.

According to the European Position Paper on Rhinosinusitis and Nasal Polyps EPOS-2012, thе pathology affects 2–4.3% of the Europe population [1]. The majority of domestic epidemiological studies show that nasal polyposis affects about 1% of the population in our country [2, 3]. From there, it can be assumed that polypous rhinosinusitis is an actual problem for at least 1.5 million citizens of our country [3]. Moreover, both domestic and foreign scientists agree that all available statistical data are strongly underestimated due to the large number of subclinical forms of this pathology and low incidence of outpatient visits [1, 2, 4, 5]. Average incidence of outpatient visits is 4.9 per 10 000  population in the Russian Federation. On top of that, the region-wise statistics vary little (3.7–5.8 per 10 000), which indicates that this type of pathology is spread uniformly [2].
