Evaluation of olfactory dysfunction in the Connecticut Chemosensory Clinical Research Center

Laryngoscope. 1988 Jan;98(1):83-8. doi: 10.1288/00005537-198801000-00017.


The olfactory test administered to patients at the Connecticut Chemosensory Clinical Research Center combines stability of outcome with sensitivity to variables known to affect olfaction (age, sex). The test, which pairs an odor threshold component with an odor identification component, readily resolves differences in function between patients and controls. It reveals differences in the distribution of functioning for various probable causes (nasal/sinus disease, postupper respiratory infection, and head trauma), proves sensitive to improvements in function caused by therapeutic intervention (ethmoidectomy, steroid administration for nasal/sinus disease), and correlates with objective signs of nasal/sinus disease (visual exam, x-ray). The two components of the test agree well, though the odor identification component seems somewhat more sensitive than the threshold component as currently designed.
