    "abstract": "Cochlear implantation (CI) is associated with postoperative vestibular dysfunction in the implanted ear; however, limited data on baseline vestibular function in these patients exists. Bilateral vestibular weakness is associated with detrimental effects on quality of life. As such, it is important to identify patients with a preexisting bilateral weakness and consider this information in surgical planning.\nRetrospective cohort study of the CI candidate population. All patients underwent routine preoperative vestibular evaluation, irrespective of symptoms.\nOf 180 preoperative videonystagmographies, 39.4% showed vestibular weakness determined by caloric testing. Of these, 26.8% exhibited bilateral weakness. Patients with bilateral weakness had higher body mass index (31.6\u2009kg/m\nMore than one-third of CI candidates have some degree of underlying vestibular dysfunction and 10.5% exhibit preexisting bilateral weakness. This study indicates that audiologic data may be a useful prognostic indicator of preexisting bilateral vestibular weakness. Given the well-documented detrimental effects of bilateral vestibular weakness on quality of life, we recommend that all patients who meet this cutoff undergo vestibular testing to assess for an underlying weakness.",
