Summary:The reported prevalence of vestibular dysfunction after cochlear implantation (CI) is varies between different scientific papers. The aim of this study is to determine the reported post-implantation outcome in terms of dizziness, and to measure its impact on quality of life using the Dizziness handicap inventory (DHI). This was a prospective questionnaire based study of postoperative cochlear implant patients. The questionnaire assessed the type and onset of dizziness in addition to the DHI. 122 patients were recruited in this study, which is the largest sample size in the literature reported so far. Dizziness was evident in 45.9% of the population post-CI and in 27% pre-CI. The commonest subtype of the dizziness was unsteadiness followed by lightheadedness. The dizziness was mild in most of the patients. Although mild, dizziness is a common complaint post-cochlear implantation. An understanding of symptoms helps counsel patients preoperatively.
