ABSTRACT

Background & Objectives: The mechanism for maintaining balance in human is dependent on visual, vestibular, proprioceptive and superficial sensory information. We supposed that another information, auditory stimulation, may affect the balance system and cause dizziness in patient with conductive hearing loss. The purpose of this study is to know whether the exclusion of sound influences the balance system. Materials & Methods: Ten otologically healthy young person were tested before and after the occlusion of right external auditory canal. Computerized dynamic posturography (CDP), electronystagmography (ENG), and rotation chair test (RCT) were done. Results: The composite score of CDP after occlusion was 78.7, which was slightly decreased comprare to before the occlusion (82.1). The phase of SHA test showed phase lead after occlusion compare to pre-occlusion. Symmetry showed asymmetric change to opposite side of occluded ear compare to pre-occlusion. Conclusions: Though statistically not verified, occlusion of external ear canal might influence the balance system. Further studies will be needed to evaluate the relationship between conductive hearing loss and balance system. (J Clinical Otolaryngol 2005;16:124–127)
