Vestibular Symptoms Remain Stable and Improve for Many Meniere's Patients After Cochlear Implant

A recent study published in the September issue of Otology & Neurotology Open indicates that most patients with Meniere's disease (MD) experience stabilization or improvement in their vestibular symptoms following cochlear implantation (CI) in the affected ear. The research, led by Alexandra M. Arambula, M.D., from the University Hospitals Cleveland Medical Center, analyzed the impact of CI on vestibular symptoms in a retrospective review of 39 patients treated between 2011 and 2024.

Preoperative assessment showed that 51% of patients had moderate to severe vestibular symptoms, while 41% experienced mild symptoms. Post-surgery, approximately 28% of patients reported symptom improvement, 64% remained stable, and about 8% experienced worsening. Notably, patients with mild or no symptoms before surgery were more likely to have stable symptoms afterward, whereas those with more severe symptoms had a higher chance of experiencing improvement.

The study also revealed that patients with moderate or severe preoperative symptoms were more prone to migraines, with 35% affected compared to only 5.3% of patients with mild or no symptoms. Among those with significant symptoms, those without migraines were more likely to see symptomatic improvement.

These findings are relevant for preoperative counseling, as they suggest that cochlear implantation generally does not worsen vestibular symptoms in most patients and can sometimes lead to improvement. The study emphasizes the importance of considering comorbid conditions like migraines when discussing expected outcomes.

While the sample size was relatively small, the results contribute valuable insights into the management of Meniere's disease and the role of cochlear implants in preserving or enhancing vestibular function.
