Background:
Understanding how sensorineural hearing loss (SNHL) impacts postural balance in patients is important, as postural balance predicts the risk of falls.
Aims/Objectives:
We aimed to clarify the relationship between characteristics in the configuration of audiograms and static postural balance as measured by posturography.
Materials And Methods:
We evaluated 385 outpatients (mean [± standard deviation] age, 58.4 ± 18.4 years) with SNHL by audiometry and posturography. Data were analysed by multiple regression models with the outcome of postural sway area with eyes closed (PSA) and predictive variables of audiometric data, adjusted for sex, age and the presence of nystagmus.
Results:
The increased hearing threshold in the better hearing ear was associated with poorer or higher PSA (beta coefficient [β] = 0.39, 95% confidence interval [CI] = 0.03-0.75, per 10-dB increment). No difference in PSA was detected between patients with asymmetric or symmetric SNHL. None of the frequent diagnoses (presbyacusis, Meniere's disease, and idiopathic sudden SNHL) were associated with poorer PSA. Hearing thresholds at middle (β = 0.39, 95%CI = 0.10-0.67) and high frequencies (β = 0.31, 95%CI = 0.07-0.55) were associated with poorer PSA, whereas those at low frequencies was not.
Conclusions And Significance:
Postural balance in neurotologic patients may be associated with middle-high-frequency hearing levels during ageing.
