High Resolution MRI Shows Presence of Endolymphatic Hydrops in Patients Still Symptomatic After Endolymphatic Shunt Surgery.
OBJECTIVE Endolymphatic hydrops has been well described in patients with Ménière's syndrome; however, causation has not been established. Decompression of the endolymphatic sac has been proposed as a means to relieve hydrops and improve vertigo symptoms, but the efficacy of the surgery is debated. Until recently, there have been few objective measures of efficacy other than patients' subjective...
متن کاملEffects of endolymphatic sac decompression surgery on endolymphatic hydrops.
CONCLUSIONS The present findings suggest that complete control of vertigo after endolymphatic sac decompression surgery (ESDS) does not always depend on improved vestibular function or reduced endolymphatic hydrops. Vertigo control is, however, associated with hearing stability. OBJECTIVE Among surgical treatments for intractable Meniere's disease, ESDS is performed to preserve and improve in...
متن کاملVasopressin induces endolymphatic hydrops in mouse inner ear, as evaluated with repeated 9.4 T MRI.
From histopathological specimens, endolymphatic hydrops has been demonstrated in association with inner ear disorders. Recent studies have observed findings suggestive of hydrops using MRI in humans. Previous studies suggest that vasopressin may play a critical role in endolymph homeostasis and may be involved in the development of Ménière's disease. In this study we evaluate the effect of vaso...
متن کاملTinnitus & early endolymphatic hydrops.
Ménière's disease with all of its clinical manifestations can be divided into two categories – those symptoms that derive from the cochlea (the anterior labyrinth) and/or those that arise from the vestibular labyrinth or the posterior part of the inner ear. The symptoms that arise from the cochlea include hearing loss, which can be fluctuant and progressive and often is, or tinnitus which can b...
متن کاملEndoscopic Middle Ear and Mastoid Surgery for Cholesteatoma
Introduction: To reduce incidence of residual cholesteatoma following ear surgery; and to reduce the need for second look “open” mastoidectomy using endoscopic mastoidotomy. Ten-year retrospective chart review of 249 primary cholesteatoma cases (1994-2004) with a minimum follow-up of two years. The first objective was to evaluate the effectiveness of otoendoscopy in reducing the incidence of “...
