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 XXX 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.
