ABSTRACT

Objective: To develop an adaptation of the Sniffin sticks^® and the TDI score that is suitable for Mexican patients with olfactory alterations secondary to SARS-CoV-2 infection.
Materials and Methods: A longitudinal, prospective, prolective, descriptive and observational study done from November 2021 to April 2022 with patients aged 18 to 65 years, who persisted with anosmia, hyposmia or other olfactory impairment following diagnosis of COVID-19. The Sniffin sticks^® and the TDI score with cultural modifications were used to assess olfactory function. Measurements were divided into three subsections.
Results: There were included 27 patients. The average time between COVID-19 diagnosis and olfaction evaluation with Sniffin sticks^® was of 9.4 months (2.9-18-5 months). The assessment demonstrated anosmia in at least one item in virtually all study participants. The mean threshold was 6.30 (95% CI, 5.757-6.843) out of eight hits, discrimination was 8.15 (95% CI, 7.46-8.84) out of 12 hits, and identification was 6.37 (95% CI, 5.506-7.234) out of 12 hits. The overall evaluation of the TDI was 0.67 (95% CI, 0.63-0.71).
Conclusions: The importance of this adaptation lies not only in giving greater credibility to these tools and in evaluating olfactory capacity in an objective manner, but also in offering the possibility of replicating this adaptation in populations with olfactory alterations of an etiology other than viral.
