Surgical treatment of otosclerosis leading to changes in postural control and quality of life.

OBJECTIVE

Evaluating postural function in patients with otosclerosis by assessing otoneurological function and balance-related quality of life before and 6 weeks after surgical treatment. Correlations between and clinical features were investigated.

METHODS

Thirty-three patients affected by otosclerosis underwent otoneurological examination, video Head Impulse Test (vHIT), and static posturography before and after stapedotomy. Quality of life and dizziness-related handicap were screened by means of validated questionnaires. Correlation analysis was performed in order to discover possible relations with audiological pre- and postoperative parameters.

RESULTS

A significant improvement in posturographic parameters was found. Correlation analysis yielded a negative correlation between preoperative bone conduction auditory threshold and both vHIT scores and postural performance improvement, evaluated by spectral analysis. Moreover, a positive correlation was also found between improvements in posturographic scores and quality-of-life questionnaires.

CONCLUSION

The study results demonstrated an improvement in postural function and self-reported measures in a cohort of patients with otosclerosis 6 weeks after stapedotomy. The inverse correlation with preoperative auditory levels may reflect lesser chance for balance restoration in cases with worse sensorineural function. Possible implications for daily activities and overall quality of life were suggested by improved self-report questionnaire results.
