Vestibular Evaluation Using Videonystagmography of Chronic Zinc Deficient Patients Due to Short Bowell Syndrome

SummaryThe presence of zinc in the auditory pathways and its probable participation in tinnitus and hearing loss are known facts, although there are no clinical trials and experimental studies showing the impact of hypozincemia in the vestibular system and zinc existence in the vestibular pathway, respectively.AimThis study is an attempt to correlate hypozincemia and abnormal vestibular function.MethodsThis is a clinical retrospective case study where nine patients suffering of chronic zinc deficiency had their serum zinc determined and were submitted to videonystagmography. Results were compared to a normal (control) group.ResultsAll vestibular test parameters were altered when we compared experimental and control groups.ConclusionComparison between groups shows significant differences in many aspects of the vestibular analysis and calls our attention towards a possible participation of zinc on the genesis of vestibular disorders.
