Using the University of Pennsylvania Smell Identification Test, they evaluated 36 consecutive patients undergoing sinus surgery. Administering this 40-item test (microencapsulated stimuli released on scratching an odor-impregnated strip) before and after surgery, the authors compared scores with standardized norms for each patient's age and gender.

Thirty patients had improved percentile scores after surgery; the mean improvement was 11.6. Six patients had decreased scores; the mean decrease was 8.6. Classifying these patients as normosic, hypomic, or anosmic, they found that more than 40% of
