Features of the clinical and functional state of the nose in patients with chronic polypous rhinosinusitis and impaired sense of smell

Introduction. According to EPOS 2020, сhronic rhinosinusitis with nasal polypsis detected in 2–4.3% of the population, in Russia about 1.5 million people suffer from polyposis. In clinical practice, attention is most often paid to indicators of respiratory function. At the same time, the assessment of olfactory impairment characteristic of CRSwNP is carried out only by answering one of the 22 questions of the SNOT-22 questionnaire, and indicators of olfactory function are rarely taken into account when evaluating the results of objective research methods. Aim. To study the features of the clinical and functional state of the nose in patients with chronic rhinosinusitis and impaired sense of smell. Materials and methods . 50 patients with сhronic rhinosinusitis with nasal polypsis were examined. The study included an assessment of the sense of smell using Sniffin Stiks test-12, a study of respiratory function, performing a video endoscopy of the nose, computed tomography of the nose and paranasal sinuses. A comprehensive assessment of the condition was carried out using the SNOT-22 questionnaire. Results . The subjective assessment of the sense of smell by patients with CRSwNP does not always coincide with the results of identification tests. The results of the SNOT-22 questionnaire often depend on the degree of olfactory impairment. Patients with CRSwNP and anosmia are more likely to complain of postnasal congestion, thick nasal discharge and cough than patients with hyposmia, which is consistent with objective research methods. Conclusions. In patients with Ghronic rhinosinusitis with nasal polypsis and varying degrees of olfactory impairment, heterogeneity of the clinical and functional state of the nasal cavity and paranasal sinuses was noted. When interpreting the results of the SNOT-22 questionnaire, it is advisable to use factor analysis, taking into account the patient’s complaints. To plan individual management of patients with CRSwNP, a comprehensive assessment of the sense of smell is necessary, including identification tests, as well as an additional assessment of the results of computed tomography of the nose and paranasal sinuses and a video endoscopic picture of the nose according to generally recognized scales.
