Abstract
BackgroundFacial palsy is known to have correlations with low level of quality of life. However, little is known about the association between preference based health-related quality of life (HRQoL) and paralytic side of facial palsy.MethodsThis study used Korea National Health and Nutrition Examination Survey (KNHANES, 2008–2012) data, only when the facial palsy examination had been included in the survey contents. Hierarchical regression analyses were used to obtain optimal regression coefficients in the association between paralytic side of the facial palsy and HRQoL measured by EuroQoL-5 Dimension (EQ-5D). We also analyzed the association between the deteriorated domains of EQ-5D and facial palsy in both subgroups by using multiple logistic regression models.ResultsWe included the data of 28,106 participants aged ≥19 years who were examined as facial palsy according to House-Brackmann score and completed EQ-5D questionnaire in KNHANES 2008–2012. The mean EQ-5D score was significantly low and percentages of deteriorated numbers in its domains were significantly high in facial palsy group.ConclusionsThese results show that, after adjusting for confounding variables, left facial palsy is associated with impaired HRQoL compared with right-sided palsy. Among the domains of EQ-5D, only ‘self-care’ domain was directly affected by the disease in left facial palsy patients. These findings could be used in developing model and conducting analyses of economic evaluation about facial palsy interventions.
Highlights
Unilateral peripheral facial nerve palsy may have a detectable cause or may be idiopathic without an obvious cause (i.e. Bell’s palsy) [1, 2]
Twenty-eight thousand one hundred six participants, who were examined as facial palsy according to House-Brackmann score and completed EuroQoL-5 Dimension (EQ-5D) questionnaire in Korea National Health and Nutrition Examination Survey (KNHANES) 2008–2012, were included in the study
Hierarchical regression analysis was used to evaluate the association between facial palsy and deterioration of health-related quality of life (HRQoL) (Table 2)
Summary
Unilateral peripheral facial nerve palsy may have a detectable cause (i.e. secondary facial nerve palsy) or may be idiopathic (primary) without an obvious cause (i.e. Bell’s palsy) [1, 2]. Secondary facial nerve palsy has a variety of causes and is generally less prevalent than Bell’s palsy (25 vs 75%) [2, 3]. Bell’s palsy is an acute peripheral facial nerve paralysis that usually affects only one side of the face [4]. Facial palsy is known to have correlations with low level of quality of life. Little is known about the association between preference based health-related quality of life (HRQoL) and paralytic side of facial palsy
