hyposmia, anosmia
Connecticut Chemosensory Clinical Research Center (CCCRC) test was used to assess olfactory function of all the patients.Threshold testing was performed presenting solutions of For the identification test, eight well-known Brazilian odorants were used: coffee, soap, Cinnamomum, At the end of the process, a final score was calculated, following the equation: average score obtained in the butanol test for both nostrils plus average of the discrimination score for the two nostrils/2, resulting in a score also from 0 to 7 that determined the degree of hyposmia. Normosmia was considered as a score between 6.0 and 7.0; mild hyposmia, from 5.0 to 5.75; moderate hyposmia, from 4.0 to 4.75, severe hyposmia, from 2.0 to 3.75, and anosmia, from 0 to 1.75.After the olfactory test, patients underwent to physical examination and nasal endoscopy.
