Dizziness after cochlear implantation: Is the age an independent risk factor?

Abstract

Abstract Background: Hearing loss and imbalance are the prevalent chronic conditions in the elderly, significantly impacting their quality of life (QoL). The relationship between otologic surgery, particularly cochlear implant (CI) procedures, and postoperative dizziness remains a critical area of investigation. Understanding this relationship is essential, especially given the rising number of older adults undergoing CI surgery. Materials and Methods: This retrospective, observational study, conducted between January 2016 and August 2021, assessed the influence of age on chronic dizziness following CI surgery. Sixty adults with postlingual sensorineural hearing loss who underwent unilateral CI surgery were evaluated. Comprehensive preoperative and postoperative assessments included the Dizziness Handicap Inventory (DHI) and QoL measures. Results: The study found a significant improvement in speech perception postimplantation, regardless of the age at surgery. However, postoperative dizziness, as measured by the DHI, increased significantly compared to preoperative levels. This increase in dizziness was not correlated with the age at implantation but was strongly associated with preexisting dizziness. Conclusions: These findings emphasize the need for thorough preoperative evaluations and patient counseling, particularly for those with preexisting balance disturbances, to optimize the outcomes and manage expectations regarding postoperative dizziness. This study contributes to the understanding of dizziness post-CI in older adults, highlighting the importance of considering individual patient conditions in the management of CI recipients.
