Tinnitus & 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 کاملSymptoms of Experimental Endolymphatic Hydrops : Possibly a Potassium Contamination from Perilymph
The cause(s) of Meniere's disease is(are) not known but two main hypotheses have been proposed and have been widely accepted, to explain the characteristic symptoms: low frequency hearing loss, tinnitus and vertigo. It is supposed that there is an overpressure within the endolymphatic spaces accompanied by fissures in the membranes, and in particular in the Reissner's membrane, which leads to t...
متن کاملComparison of contrast effect on the cochlear perilymph after intratympanic and intravenous gadolinium injection.
BACKGROUND AND PURPOSE 3D-FLAIR imaging 24 hours after intratympanic gadolinium injection (IT-method) or 4 hours after IV injection (IV-method) has been used to visualize the endolymphatic hydrops in Ménière disease. The purpose of this study was to compare the degree of perilymph enhancement with the 2 methods and the perilymph contrast-effect difference with the IV-method in both sides in pat...
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 کاملSpiral ganglion degeneration patterns in endolymphatic hydrops.
OBJECTIVES The mechanistic association between endolymphatic hydrops (ELH) and hearing loss (HL) is unclear. Although ELH severity has been shown to correlate in some studies with HL, injury of vital structures, including hair cells and the cochlear nerve, have failed to demonstrate correlation with ELH severity. The goal of this study is to evaluate the hypothesis that spiral ganglion cell deg...
