Gustatory rhinitis

Gustatory rhinitis is a conspicuous type of food-associated rhinorrhea, which can occasionally be associated with significant quality-of-life impairment. It results from an abnormal gustatory reflex associated with a hyperactive, nonadrenergic, noncholinergic, or peptidergic neural system. The use of nasal ipratropium bromide may be effective, if avoidance is not possible or successful. We have had excellent results with the use of intranasal capsaicin or endoscopic vidian neurectomy (including removal of 4-5 mm of the nerve between pterygopalatine fossa and the sphenoid floor) in patients with nonallergic rhinitis, and these could potentially be used as a last resort in patients with intractable gustatory rhinitis.
