Rate of vertigo control higher after cochlear implantation alone versus endolymphatic sac surgery alone or with cochlear implant
By Elana Gotkine HealthDay Reporter
MONDAY, Aug. 7, 2023 (HealthDay News) — For patients with Meniere disease (MD), vertigo control is improved with endolymphatic sac surgery alone (ESSalone), cochlear implantation alone (CIalone), and ESS with CI (ESS+CI), with the highest rate for CIalone, according to a study published online July 20 in the European Archives of Oto-Rhino-Laryngology.
Jennifer L. Spiegel, M.D., from University Hospital in Munich, Germany, and colleagues conducted a retrospective data analysis of 86 consecutive patients with MD according to current diagnostic criteria after ESSalone, CIalone, and ESS+CI (45, 12, and 29 patients, respectively) treated at a tertiary referral center.
The researchers found that patients in the ESSalone group had younger age compared with CIalone or ESS+CI (56.2 Â± 13.0 years versus 64.2 Â± 11.4 and 63.1 Â± 9.7 years, respectively). Definitive MD was seen in 100, 79.3, and 59.6 percent of the CIalone, ESS+CI, and ESSalone patients, respectively. The rate of vertigo control was 100, 89.7, and 66.0 percent in the CIalone, ESS+CI, and ESSalone groups, respectively.
“Data from the current study showed vertigo improvement after both ESS and CI,” the authors write. “However, it suggests a beneficial effect of CI surgery in comparison with ESS regarding vertigo control, potentially contributed by the manipulation of both the endo- and perilymphatic system.”
