In the present work, the morphological features of chronic polyposis rhinosinusitis in the tissues of the polyposis-altered mucosa of the nasal cavity are investigated. Morphological differences in the polyposis-altered mucosa of the nasal cavity have been established, which can be divided into several types. Each type of HPRS has its own characteristics, there are polyps with minimal vascularization or complete absence of blood vessels and numerous polymorphic-cellular infiltrates as well as disturbances in the interaction of factors inhibiting the pathological process, inflammatory cells (lymphocytes, granulocytes, mast cells, monocytes), which together with neuropeptides have an effect on the mucosa of the nasal cavity.
