Patientswith COPD without any nasal disease or systemic disease were included in the study. After routine ear nose throat examination wasperformed, patients with no nasal pathology had the saccharin test and Sniffin’ Sticks tests applied. The control group consistedof volunteers that were living in the same region. The same tests applied to the control group too and the results were compared.Results: There were no significant differences between patient group and control group in terms of categorical variables such asgender, age, smoking status, living area... It was found that the odor functions of COPD patients were significantly affected whencompared with the control group. Odor test results were significantly lower in the patient group (p: 0.0001). In addition, mucociliaryfunction was decreased in COPD patients.Conclusions: It was found that the smell and mucociliary functions of COPD patients were worse than the individuals of the sameage and this situation had a significant effect on the quality of life of the patients.eninfo:eu-repo/semantics/openAccessSolunum SistemiGenel ve Dahili TıpKulakBurunBoğazArticle2691964196810.5455/annalsmedres.2019.05.257318411
