Vasomotor rhinitis.

Vasomotor rhinitis is a nonallergic, noninfectious cause of nasal obstruction and rhinorrhea. The etiology is believed to be an imbalance of the autonomic neural supply to the nasal mucosa with resultant vasodilation and hypersecretion. Management hinges on identification of a treatable diagnostic entity, such as rhinitis medicamentosa or allergic rhinitis. Psychotherapy, medical therapy, and surgery all have roles in the treatment of vasomotor rhinitis. Response to therapy is often disappointing.
