anatomically designated areas in the nose. The internal valve is present in each side of the nose at the upper edge of the hair bearing area inside the nose. The outer valve is at the edge of the nostril rim. The valves work together keeping the airway open but can potentially collapse giving rise to diminished airflow on inspiration. The treatment for nasal valve collapse is to furnish additional support to nasal architecture in the form of bone, cartilage or synthetic material.
