Endolymphatic hydrops (EH) has long been considered the primary pathological feature of Meniere's disease (MD). Consequently, most existing animal models of MD are EH models, yet they cannot fully reflect all the pathological features of MD. Moreover, the causal relationship between EH and MD remains controversial....

No actionable change for clinical practice; this is a preclinical animal model study that may accelerate future research into Meniere's disease mechanisms and therapies, but has no direct patient-care implications today.
A reproducible and validated animal model of Meniere's disease would be a significant methodological advance, potentially enabling more targeted drug discovery and mechanistic research for a condition with poorly understood etiology.
- 01Novel animal model of Meniere's disease created via postauricular (behind the ear) injection of an inflammatory cocktail.
- 02Primary pathological target is endolymphatic hydrops — abnormal fluid buildup in the inner ear.
- 03Model aims to more closely mimic the inflammatory aspects of human Meniere's disease.

- 05Preclinical only; human translation and validation are still required.
