摘　　要：Objective:Patients with dizziness may present with symptoms of tilting,swaying,rocking,floating or with disequilibrium.This may be suggestive of an isolated otolithic dysfunction yet,there is little emphasis on this emerging clinical entity.To characterize and describe the prevalence of isolated otolith dysfunction in a local tertiary hospital and correlate them with clinical diagnosis.Methodology:Retrospective medical chart review of patients who presented with dizziness to the specialist outpatient Otolaryngology clinic,who required vestibular laboratory investigation.Results:Of the 206 patients,more than half of them(52.4%)fulfilled the criteria for either probable or definite isolated otolith dysfunction.When there are clinical symptoms of otolith dysfunction reported,there is a 1.62 odds of a remarkable laboratory otolith finding.The most common clinical finding was“no clear diagnosis”(65.5%)followed by Vestibular Migraine(13.6%).Conclusion:The prevalence of isolated otolith dysfunction is quite high.Laboratory tests of otolith function should be performed more routinely.This can be done in a sequential way to optimize cost effectiveness in countries with no insurance reimbursement.Prospective cohort studies on isolated otolith dysfunction,will lay the groundwork for achieving diagnostic consensus and formulating rehabilitation plans to aid this group of patients。
