Olfactory testing
Healthy controls were categorized as normosmic, obtaining the maximum
scores at olfactory testing, in contrast with the patient group that
obtained scores between 1 and 7, which characterize them as anosmic and
hyposmic(18).
The patient group was evaluated initially with the “Sniffing Stick
Screening test” observing no significant differences between the
treatment and no-treatment groups before training. All patients in the
treatment group improved to a normosmic level, in comparison with the
control group, where the 3 patients maintain their anosmic status.
Comparison of olfactory test after training showed a significant
improvement in the treatment group (P < 0.05), as shown in
detail in Table 2. After conversion table application to the screening
scores, a six-point difference was observed between the scores of two
patients in the treatment group before and after olfactory training
(Table 3).
