Summary
Dizziness is a common side effect following cochlear implantation (CI), affecting nearly half of patients. Understanding these vestibular dysfunction symptoms can improve preoperative patient counseling.
Area of Science:
- Audiology
- Otolaryngology
- Vestibular Science
Background:
- Vestibular dysfunction prevalence post-cochlear implantation (CI) varies significantly in reported literature.
- Assessing the impact of post-CI dizziness on patient quality of life is crucial.
Purpose of the Study:
- To determine the prevalence of dizziness after cochlear implantation.
- To measure the impact of post-implantation dizziness on quality of life using the Dizziness Handicap Inventory (DHI).
Main Methods:
- Prospective, questionnaire-based study involving postoperative cochlear implant patients.
- Assessment included the type and onset of dizziness and the DHI.
Main Results:
- A total of 122 patients were recruited, representing the largest sample size reported to date.
- Dizziness was reported in 45.9% of patients post-CI, compared to 27% pre-CI.
- The most common dizziness subtypes were unsteadiness and lightheadedness, generally mild in severity.
Conclusions:
- Mild dizziness is a frequent complaint after cochlear implantation.
- Preoperative understanding of these symptoms can enhance patient counseling and management.
