Meniere's Disease

What is Meniere's Disease?
Meniere's disease is a vestibular disorder characterized by recurrent episodes of vertigo, fluctuating sensorineural hearing loss, tinnitus, and aural fullness associated with endolymphatic hydrops.
Diagnostic criteria were established by the Bárány Society in López‐Escámez et al. (2015, 1373 citations), requiring two or more vertigo episodes lasting 20 minutes to 12 hours, audiometrically documented low- to medium-frequency sensorineural hearing loss, and fluctuating aural symptoms. Nakashima et al. (2007, 604 citations) visualized endolymphatic hydrops in Meniere's patients using MRI after intratympanic gadolinium injection. Sajjadi and Paparella (2008, 555 citations) reviewed pathophysiology linking hydrops to episodic symptoms.
Why It Matters
Standardized diagnostic criteria from López‐Escámez et al. (2015) enable consistent patient identification across clinics, improving clinical trial recruitment and outcome tracking. Visualization techniques by Nakashima et al. (2007) confirm endolymphatic hydrops as a biomarker, guiding surgical decisions like endolymphatic sac decompression. Pharmacological insights from Selimoğlu (2006) on aminoglycoside ototoxicity inform gentamicin therapy risks, reducing vertigo recurrence while preserving hearing in 70-80% of intractable cases.
Key Research Challenges
Diagnostic Differentiation
Distinguishing Meniere's from vestibular migraine and PPPD relies on symptom overlap, with López‐Escámez et al. (2015) criteria requiring exclusion of central causes. Lempert et al. (2012, 1063 citations) vestibular migraine criteria and Staab et al. (2017, 729 citations) PPPD criteria complicate definitive diagnosis. No single biomarker exists beyond hydrops visualization (Nakashima et al., 2007).
Endolymphatic Hydrops Mechanism
Pathophysiology linking hydrops to symptoms remains unclear, as hydrops appears in asymptomatic ears (Nakashima et al., 2007, 604 citations). Sajjadi and Paparella (2008) note multifactorial etiology including genetic and autoimmune factors. Longitudinal studies tracking hydrops progression are limited.
Therapy Side Effect Management
Intratympanic gentamicin controls vertigo but risks hearing loss via ototoxicity (Selimoğlu, 2006, 422 citations). Balancing vestibular ablation with hearing preservation challenges personalized dosing. Surgical options like sac decompression lack randomized trials (Sajjadi and Paparella, 2008).
