Single-Stage Surgical Treatment of Concurrent Meniere's Disease and Superior Semicircular Canal Dehiscence: A Case Report
Year: 2026
Type: article
Study design: Case Report
Abstract: A 34-year-old woman with concurrent Meniere's disease (MD) and superior semicircular canal dehiscence (SSCD) presented with third-window-mediated drop attacks and episodic vertigo refractory to conservative medical management. The coexistence of these conditions and the pattern of presentation suggested overlapping inner-ear pathophysiology in which abnormal third-window mechanics potentiated MD symptoms. The patient underwent a single-stage transmastoid superior semicircular canal plugging and endolymphatic sac decompression to address both aberrant labyrinthine pressure transmission and impaired endolymphatic regulation. Postoperatively, the patient experienced complete resolution of vertiginous episodes and third-window symptoms without significant impact on hearing. Review of the literature revealed no prior reports of single-stage surgical management of concurrent MD and SSCD. This case describes the complex decision-making and considerations involved in treating a patient with multiple vestibular disorders and highlights the potential role of addressing abnormal intracranial and inner ear pressure dynamics when multiple conditions coexist.
