CLINICAL MANIFESTATIONS OF VASOMOTOR RHINITIS

Abstract

Vasomotor rhinitis is a chronic rhinitis characterized by episodes of sneezing and nasal congestion, as well as profuse watery nasal discharge. The underlying cause is excessive dilation of mucous membrane blood vessels in response to environmental irritants. The nature of vasomotor rhinitis remains unclear. It is believed that impaired vascular tone occurs due to dysfunction of the sympathetic and parasympathetic divisions of the nervous system. In vasomotor rhinitis, the parasympathetic division, which is responsible for vasodilation, predominates. It is estimated that approximately 10% of the population experiences this condition to varying degrees. It is worth noting that vasomotor rhinitis is a hypersensitive reaction to any environmental irritant, unlike allergic rhinitis, which is caused by an immune response to proteins, pollen, pet dander, mold, etc...
