Evaluation of Compensation in Peripheral Vestibulopathy / 대한이비인후과학회지

ABSTRACT

The initial severe and disabling symptoms of vestibular dysfunction diminish gradually by a process of compensation. Although the process is complex and not fully understood, knowledge of the extent of compensation makes physicians to identify the causes and to determine treatment choices of the dysfunction. In this report we present 2 common cases of peripheral vestibulopathy that result from different disease processes, and review the physiologic and functional changes as the compensation proceeds that can be evaluated by vestibular function tests including electronystagmography(ENG), rotation chair, and dynamic posturography. These tests are valuable tools in the assessment of the degree of compensation as well as the side and site of lesions in vestibulopathy.
