Treatment of Menière's disease: a scoping review of the current evidence.

Purpose: The management of unilateral Menière's disease (MD) in adult patients remains contentious, with various therapeutic options proposed but no established gold standard. This scoping review aims to evaluate the current treatment options for unilateral MD, identifying challenges in management and providing guidance for ENT physicians in selecting effective therapies.

Methods: A comprehensive literature search of the MEDLINE and Embase databases was conducted without date restrictions, assessing various treatment modalities for MD. Randomized controlled trials (RCTs) were selected to ensure the highest quality of evidence was reviewed.

Results: Thirty-four RCTs met the inclusion criteria. The current evidence base encompasses dietary interventions, systemic drug therapy, intratympanic treatments, positive pressure therapy, low-level laser therapy, and non-destructive surgical techniques. However, the evidence supporting these treatments is limited and inconsistent. Notably, none of the RCTs considered the heterogeneity of MD patient populations, which may explain the variability in study results.

Conclusion: This review highlights the limited evidence supporting current treatments for unilateral MD, emphasizing the need for high-quality, placebo-controlled trials. Future research should incorporate biomarker-based stratification, large patient cohorts, standardized outcome measures, and long follow-up periods to enhance the consistency and comparability of findings.
