Triple Semicircular Canal Occlusion Combined with Endolymphatic Sac
Decompression: An Effective Surgical Strategy for Vertigo Control of
Intractable Meniere’s Disease
Abstract
Objective: To investigate the symptomatic relief and functional
preservation of a novel surgical strategy combined with triple
semicircular canal occlusion and endolymphatic sac decompression in
patients with intractable Meniere’s disease. Design: Retrospective
analysis. Setting: Patients with intractable Meniere’s disease in the
Department of Otolaryngology Head & Neck in the Second Affiliated
Hospital of Nanchang University between July 2015 and June 2019.
Participants: Data from 46 patients diagnosed with Meniere’s disease,
and underwent surgery Methods: Triple semicircular canal occlusion
combined with endolymphatic sac decompression was performed in all
patients with intractable Meniere’s disease. Pre- and postoperative
vertigo attacks, hearing levels, tinnitus, aural fullness, and
equilibrium function rehabilitation were analyzed at defined time points
during follow-up. Results: A significant vertigo control rate was
observed in all patients postoperatively. The overall control rate of
vertigo postoperatively was 100% in the entire follow-up, with a
complete control rate of 97.8% and a substantial control rate of 2.2%.
The rate of hearing preservation was 54.35%, and all patients suffering
from hearing deterioration were at stages III and IV. The rate of
tinnitus and aural fullness alleviation was 65.8% and 100%,
respectively. Four patients failed to regain the equilibrium function
postoperatively. Conclusion: Combining triple semicircular canal
occlusion with endolymphatic sac decompression is an efficient strategy
for vertigo control in patients with intractable Meniere’s disease.
Patients in advanced stages suffered more from hearing function
deterioration. Hearing preservation and tinnitus alleviation warrant
further investigation.
