Non-allergic rhinitis involves chronic sneezing or having a congested running nose. The symptoms of non-allergic rhinitis are similar to symptoms of allergic rhinitis, but there is no identified allergic reaction involved. Non-allergic rhinitis can affect children and adults, but is usually seen after the age of 20. Many surgical techniques are available to treat inferior turbinate hypertrophy, including submucous resection with or without outfracture, cryotherapy, laser cauterization, electrocauterization, and/or turbinectomy. A randomized control trial of 382 patients with 6-year follow-up was conducted to evaluate submucous resection with lateral displacement (outfracture) in terms of efficacy and complications, and found outcomes to be statistically better than turbinectomy, laser or cryotherapy, or electrocautery.
According to the ECRHS (European Community Respiratory Health Survey) and International Study of Asthma and Allergies in Childhood studies, Non allergic rhinitis (NAR) is a common pathology across Europe, with a prevalence that is constantly increasing. The estimated prevalence of clinically confirmed AR across France ranges from 21.0% to 28.0%, with an average prevalence of 24.5%, and 30–35% in the ECRHS survey. To use an analogy, consider the skin. Poison ivy contains a chemical which causes an itchy rash to develop. This reaction is not because of an allergic reaction or infection but rather due to the chemical physically irritating the skin. For patients with non-allergic rhinitis, common air particulates act like poison ivy to the sino-nasal lining.
