The aim of the study is to investigate the association between olfactory dysfunction (OD), hearing loss, and dysphonia. The cross-sectional data for 17,984 adults who completed the Korea National Health and Nutrition Examination Surveys (2010-12) were analyzed. OD, hearing loss, and dysphonia were assessed using self-reporting questionnaires. The association of OD with hearing loss and dysphonia was evaluated. Hearing loss and dysphonia were significantly more prevalent in patients with OD than in those without OD (hearing loss, 28.1% vs 11.3%; dysphonia, 11.1% vs 5.9%; both P < .0001). After adjusting for confounders, including mental stress and metabolic syndrome, the risk of OD was significantly associated with hearing loss and dysphonia, and was greater in those with combined hearing loss and dysphonia than in both patients without these dysfunctions and in those with a single dysfunction (odds ratio 3.115, 95% confidence interval 1.973-4.917). OD was significantly associated with hearing loss and dysphonia.
