Self-perception of balance function in adults following cochlear implant surgery: A cross-sectional study

OBJECTIVE: To assess self-perceived balance function in adults after cochlear implantation and explore factors associated with postoperative vertigo. METHODS: A cross-sectional questionnaire-based study was conducted among adult cochlear implant recipients (≥18 years). Collected data included demographics, hearing history, vestibular symptoms before and after implantation, and satisfaction with hearing outcomes. Chi-square analysis was used to examine associations between vertigo and clinical variables. RESULTS: A total of 50 adult participants were included. Perception of vertigo was reported by 38% prior to implantation and 48% post-implantation. Among those with post-implant symptoms, 58.3% experienced vertigo daily, and 54.2% rated their symptoms as moderate in severity. The majority of symptoms developed within one month post-surgery. Male sex was significantly associated with a higher incidence of post-implant vertigo (p = 0.049), while no significant associations were observed with other factors. CONCLUSION: Nearly half of adult cochlear implant recipients reported postoperative vertigo, with many describing symptoms of moderate severity that interfered with daily activities. These findings underscore the importance of incorporating systematic pre- and post-operative vestibular assessment and follow-up into standard cochlear implant care.
