ABSTRACT
Abstract. Introduction. Olfactory impairment is becoming an increasingly common symptom, according to statistics. About 20% of the population have olfactory disorders of various etiologies. In 21% of cases, the cause of olfactory dysfunction is pathology of the nose and paranasal sinuses. The study of the sense of smell has become widely used in clinical practice; however, the use of identification tests on an outpatient appointment is not always available and technically feasible. At the same time, according to international studies, the possibility of self-assessment of the patient’s sense of smell may be distorted. Therefore, it is recommended to use questionnaires that take into account various aspects of olfactory function, which include the questionnaire of Olfactory Disorders – Negative Statements Factor Analysis (QOD-NS). Objective. To conduct a comparative analysis of the methods of self-assessment of the sense of smell using the QOD-NS questionnaire and the Sniffin Sticks Test-12 (SST-12) identification test. Patients and methods. The study group included 100 patients who were treated for diseases of the nose and paranasal sinuses in the department of otolaryngology of the Samara State Medical University from March to August 2023. Results. According to the survey, in 25.9% of cases, patients with pathology of the nose and paranasal sinuses could not accurately assess the state of their olfactory function. The self-assessment of the sense of smell performed using the QOD-NS questionnaire showed high accuracy and correlation with the result of the assessment of the identification of odors using the SST-12. It was possible to determine the mean value and standard deviation of scores in the QOD-NS questionnaire characteristic of normosmia, hyposmia, and anosmia (43±7.2, 34.7±8.8, and 30.4±6.7 points, respectively). Conclusion. Given the complexity of the mechanisms of pathogenesis of olfactory impairment, it is advisable to take an integrated approach to the assessment of olfactory function using questionnaires that take into account various aspects of olfactory impairment and the quality of life of the patient.
