Results of the assessment of olfactory function according to the data of the ReviSmell automated software system in patients with rhinosinusitis

Aim – to evaluate the olfactory function in patients with acute and chronic rhinosinusitis using the data from the hardware and software complex “ReviSmell”, taking into account the perception of simple and binary odors. Material and methods. At the first stage, the sense of smell was assessed using the “Sniffin Sticks screening test 12” (SST-12) in 69 patients with acute and chronic rhinosinusitis who were treated in the Clinics of the Samara State Medical University. The second stage of the study involved 52 patients with rhinosinusitis who were diagnosed with olfactory impairment. Patients were divided into two groups, with acute rhinosinusitis (n = 18 people, average age 37.7±15.9 years), and with chronic rhinosinusitis (n = 34 people, average age 39.0±0.2 years), to assess the olfactory function using the “ReviSmell” complex. Results. According to the SST-12 data, the average score in patients with chronic and acute rhinosiniusitis was 7.5±0.2 points and 7.7±1.7 points, respectively. In patients with acute rhinosinusitis, odor perception distortion was observed in 44.4% of patients, no cases of phantosmia were found. Patients with acute rhinosinusitis recognize and identify odors with both olfactory and olfactory-trigeminal action quite well. In patients with chronic rhinosinusitis, parosmia occurs in 23.5% of cases, no patients with phantosmia were found. The worst recognition and identification of binary odorants was revealed, in particular, odorants of eucalyptus, wormwood and mint. Conclusions. Patients with acute and chronic rhinosinusitis and olfactory impairment perceive odorants that irritate olfactory and olfactory-trigeminal receptors differently. The revealed differences have practical significance for differentiated assessment of individual profile of olfactory dysfunction and prediction of possibility of its correction.
