Abstract
Chronic sinusitis has been recognized to be a contributing factor to asthma in some patients. We report a 5-year follow-up study of 16 patients who had undergone bilateral sphenoethmoidectomy after not responding to aggressive medical management of underlying sinusitis. Sixty-two percent had subjective improvement of their asthma with 88% of the patients reporting a significantly reduced prednisone requirement. All patients had improvement of their nasal and sinus symptoms at 5 years. The improvement in the asthma reported at 2 years had for the most part persisted at 5 years.
