SynopsisVasomotor rhinitis is the term used to describe symptoms of nonallergic rhinitis. Although its pathophysiology is not completely understood, it is thought to be a result of blood flow abnormalities leading to inflammation of the nasal mucosa. Recent theories have suggested an immunoglobulin E (IgE)-mediated mechanism or autonomic dysfunction as proposed mechanisms.
Triggers of vasomotor rhinitis include changes in barometric pressure or temperature, cigarette smoke, fumes, odors, dust, and food. Common signs and symptoms include clear nasal drainage, nasal obstruction, postnasal drip, and rhinorrhea. For this condition to be considered chronic, symptoms must be present for at least one year.
The prevalence of vasomotor rhinitis is about 23% worldwide. Although there are no known predisposing factors, it tends to have a predilection for those who suffer from allergic rhinitis. Because changes in temperature can bring about symptoms of vasomotor rhinitis, there may be a seasonal pattern to its presentation.
