Researchers conducted this study to evaluate the clinical significance of endoscopic vidian neurectomy on bronchial asthma outcomes in patients with coexisting refractory allergic rhinitis and asthma.

Ninety-five patients were followed up for at least three years. Postoperative Rhinoconjunctivitis Quality of Life Questionnaire and Visual Analog Scale scores were significantly lower than preoperative scores during follow-up in group 1. They were considerably lower than those of group 2. Postoperative scores of the Asthma Quality of Life Questionnaire at the three follow-up time points were higher than the preoperative scores in group 1. The Total Asthma Symptom Score was not significantly decreased in group 1. The medication scores for allergic rhinitis and asthma were gradually reduced after surgery. At the end of the follow-up, the improvement rates for allergic rhinitis and asthma were 90.6% and 45.3%, respectively. Asthma outcomes were significantly improved by controlling rhinitis symptoms in patients whose asthma attacks were induced by “rhinitis onset” or “weather change.”

The study concluded that controlling allergic rhinitis symptoms by bilateral endoscopic vidian neurectomy can significantly improve asthma outcomes in patients whose asthma attacks are induced by rhinitis onset and cold air.
