Abstract
This study attempted to determine whether or not nasal and sinus surgery had a beneficial or deleterious effect upon the asthma of patients with nasal polyps and aspirin idiosyncrasy. There were 205 patients in this study. A classification system was devised to provide a means of determining the severity of asthma before and after surgery. The data indicate that surgery does improve the patient's asthma for relatively long periods of time.
