Meniere's Disease

Area of Science:

• Otolaryngology
• Neurology

Background:

• Meniere's disease (MD) is a complex inner ear disorder characterized by episodic vertigo, hearing loss, tinnitus, and aural fullness.
• Recent research has revisited the underlying pathology, diagnostic challenges, and therapeutic strategies for MD.

Purpose of the Study:

• To review recent advancements in understanding the pathologic mechanisms of Meniere's disease vertigo.
• To evaluate the evolution and limitations of diagnostic criteria for MD.
• To provide an updated overview of current and emerging medical and surgical treatments for MD.

Main Methods:

• Review of current literature on Meniere's disease, focusing on vertigo mechanisms, diagnostic criteria revisions, and treatment efficacy.
• Analysis of hypotheses regarding endolymphatic hydrops and vertigo triggers.
• Evaluation of evidence supporting various therapeutic interventions, including intratympanic medications and cochlear implants.

Main Results:

• The study suggests that vertigo in MD is unlikely caused by membrane ruptures, proposing instead a sudden shift of endolymph from the cochlea to the pars superior.
• Diagnostic criteria, including the 2015 revision, have improved but may still require further refinement to differentiate MD from vestibular migraine.
• Intratympanic steroid and gentamicin therapies show promise, and the role of cochlear implants in advanced cases is being explored.

Conclusions:

• The understanding of Meniere's disease pathophysiology is evolving, with new hypotheses on vertigo generation.
• Diagnostic accuracy for MD continues to be refined, emphasizing the interplay between cochlear and vestibular symptoms.
• Current treatment strategies for MD encompass updated evidence for established therapies and novel approaches like intratympanic medications and consideration of cochlear implants.
