3.5 Sniffin’ Sticks and patient-reported olfactory outcomes
The use of the Sniffin’ sticks showed anosmia in the majority of the patients (n=39, 14 males, 25 females) on the first examination. Hyposmia was found in the remaining 14 patients (6 males, 8 females) on the first examination. The average of the right answers was 2,84. On the second exam, we have found that 4 patients had normosmia (3 males, 1 female), 17 had hyposmia (6 males, 11 females), but 32 still had anosmia (12 males, 20 females). The average of the correct answers was 6,62.
Comparing the results of the first measurement in the patients’ group to those of the healthy subjects, a significant statistical difference (p=0.0024) was found. The difference between the results of the second measurement and those of healthy controls was less, at the p = 0.02-level. The average of the correct answers by the Schniffin-Stick’s Test was 11,62.
