Endolymphatic hydrops (can only be diagnosed by postmortem histopathological examination of temporal bone) Immunological Mechanism Genetic Predisposition (AD inheritence) Viral Predisposition not proved Vascular Etiology (Migraine Association) (VIG viral vascular, immunological, genetic) RUPTURE THEORY Periodic ruptures of the membranous labyrinth, which result in leakage of the potassium-rich ...

both genetic and environmental factors seem to play role in the etiology of meniere's disease (md). several genes may be involved in susceptibility of md including human leukocyte antigens (hla). the associations between md and hla alleles have been previously studied in other populations and certain hla alleles were shown to be predisposing. the aim of this study was to determine the associati...

Our experience with 102 patients having superior semicircular canal dehiscence confirm that the clinical manifestations of the disease are very diverse; we also identified 3 patients who showed Meniere-like symptoms. Clinical examination during an acute vertigo attack of a patient with Meniere disease for several years and whom we subsequently diagnosed as having large superior semicircular can...

background: meniere’s disease (md) is a chronic illness defined as an idiopathic syndrome of endolymphatic hydrops. benign paroxysmal positional vertigo (bppv) is a balance disorder and can be the sequel of diverse inner ear impairments. objectives: the purpose of this study was to investigate the prevalence of bppv in md patients. materials and methods: all patients with definite or probable m...

Introduction The nature and extent of membrane damage encountered in Meniere disease remains unexplained. Pressure-induced membrane stress may underlie the characteristic hydropic distention. Analysis of stress in the several vestibular chambers may offer insight into the nature and progression of Meniere disease. Objective Membrane stress levels will be assessed by constructing a specific mode...

Background: Meniere’s disease is a clinical disorder defined as the idiopathic syndrome of endolymphatic hydrops. has prevalence about 200 cases per 100,000 people in United States. Prevalence increases linearly with increasing age, especially over 60 years. Men and women are estimated to be proportional number cases. The etiology currently known caused by intrinsic factors extrinsic factors. S...
