ABSTRACT
OBJECTIVE:
To evaluate associations between self-perceived chemosensory functions of smell, taste, and flavor perception with olfactory-specific quality of life (QoL) in patients with olfactory dysfunction (OD) and whether these associations would be influenced by other factors, such as duration or etiology of smell loss. STUDYDESIGN:
Retrospective cohort study.SETTING:
Tertiary care, academic center.METHODS:
Olfactory-specific QoL was measured with the Questionnaire of Olfactory Disorders (QOD). The QOD measures the impact of OD on QoL (QOD-negative statements) and the ability of patients to cope with smell loss (QOD-positive statements). Orthonasal olfactory function, patients' demographics, self-perceived chemosensory perception, and duration and etiology of OD were retrospectively collected in a cohort of patients with quantitative OD. Correlations and multivariable linear regression models were computed to determine possible associations with the outcome measure of QOD-negative and QOD-positive statement scores.RESULTS:
A total of 133 patients with OD were included. Analysis revealed a positive correlation between self-perceived taste and flavor perception with QOD-negative statement scores, while self-perceived smell showed no significant correlation. Similarly, longer duration of smell loss and higher age were also correlated with higher QOD-positive statement scores. Multivariable regression models confirmed that self-perceived taste was independently associated with the QOD-negative statement score, while age and duration of OD were independently associated with the QOD-positive statement score.CONCLUSIONS:
These findings suggest that the impact of diminished flavor perception during eating and drinking has a stronger impact on the QoL of patients with OD as compared with decreased orthonasal olfaction.Key words
