Nonallergic rhinitis (NAR) describes chronic symptoms of nasal congestion, obstruction, and rhinorrhea unrelated to a specific allergen based on skin or serum testing. Vasomotor rhinitis is the most frequent subtype of NAR. Although medical management is the first-line treatment of NAR, there is a role for surgical therapy when medications fail to improve symptoms. Surgical options for NAR include inferior turbinate reduction and botulinum toxin injection as well as more directed targeting of the autonomic nerve supply to the nasal cavity through vidian neurectomy, posterior nasal neurectomy, and cryoablation of the posterior nerve.
