Experiemental Model for Ménière’s Disease Using Surgical Ablation of Endolymphatic Sac: Minbum Kim, Mi Joo Kim; Res Vestib Sci. 2016;15(4):95-100. Published online December 12, 2016; DOI: https://doi.org/10.21790/rvs.2016.15.4.95

Abstract PDF: Endolymphatic hydrops is a representing pathologic finding of Ménière's disease. For the induction of endolymphatic hydrops in an animal model, surgical ablation of endolymphatic sac has been used. Although traditional model with the blockage of endolymphatic sac induced severe hydrops, it has several limitations for the study of pathophysiology of Ménière's disease. Recently, modified experimental models have been introduced, in which additional procedure was performed to induce the acute aggravation of hydrops after the surgical ablation. These new models could be helpful to elucidate the mechanism and develop a new treatment of Ménière's disease. In this review, we introduce the characteristics of animal models using surgical ablation of endolymphatic sac from the classical model to novel modified models.

A History for Experimental Animal Models of Endolymphatic Hydrops: Hyun Ji Kim, Kyu-Sung Kim; Res Vestib Sci. 2016;15(3):65-69. Published online September 15, 2016; DOI: https://doi.org/10.21790/rvs.2016.15.3.65

Abstract PDF: It is known that endolymphatic hydrops is a pathophysiologic mechanism of Meniere’s disease, while the detailed role is not fully clarified. Study for endolymphatic hydrops mainly represents a pathologic histologic finding found only in the post-mortem examination of temporal bone, so endolymphatic hydrops animal models have played important role in terms of understanding how hydrops affects the function of the inner ear. Numerous challenges with diverse animals and techniques have been tried to reveal the possible pathophysiology of endolymphatic hydrops and develop an effective treatment. This review shows historical background and technical advances in experimental animal model for endolymphatic hydrops and Meniere’s disease.
