ABSTRACT
INTRODUCTION:
Vascular disorder is considered one of the main mechanisms of sudden sensorineural hearing loss (SSNHL) due to the anatomy of the inner ear. One factor that can contribute to vascular disorder is impairment in the autonomic nervous system. This study aims to investigate autonomic function in patients with SSNHL and its association with prognosis and disease severity from January 2018 to October 2019.METHODS:
We conducted a cross-sectional study involving 40 healthy controls and 55 subjects with SSNHL. We compared the autonomic function of controls and patients using heart rate variability (HRV). SSNHL patients were divided into improvement and no-improvement groups and into mild and severe groups according to pure-tone audiometry results.RESULTS:
The SSNHL group had significantly decreased total power (TP), low frequency (LF), and high frequency (HF) compared to the control group. However, there were no significant differences between the mild and severe groups. In the no-improvement group, LF was significantly higher and normalized HF was significantly lower than in the improvement group. According to a multiple logistic regression analysis, age and LF were significantly correlated with improvement.CONCLUSION:
This is the first study to evaluate the significance of HRV in patients with SSNHL, according to prognosis and disease severity. Further studies about the relationship between autonomic nervous system and SSNHL with larger sample size and prospective design are needed.Palabras clave
