The present study was to explore the functional and morphological changes in cochleas of guinea pig models of early endolymphatic hydrops. Thirty albino guinea pigs were randomly divided into three groups: control, 4-week model and 8-week model groups. For each group, n = 10. Model groups were
OBJECTIVE
Histologic analysis of the hydropic and normal guinea pig cochleae was undertaken to assess a potential correlation between the magnitude of endolymphatic hydrops and hearing loss. It was hypothesized that a greater correlation than previously reported might be found by looking at
CONCLUSIONS
Otolithic vertigo is sometimes accompanied by hearing loss. Otolithic vertigo accompanied by hearing loss seems to be caused by sacculocochlear endolymphatic hydrops.
OBJECTIVE
To clarify the lesion site and pathophysiology of otolithic vertigo (OV) accompanied by hearing
Since 1979, when McCabe first described a pattern of bilateral sensorineural hearing loss (SNHL) characterized by a rapid progression over days to weeks, the postulated autoimmune basis of this disease remains unknown. Various attempts have been made to develop the best assays that will clinically
An explanation for the mechanical origin of the hearing loss in endolymphatic hydrops is presented that is based on studies in mechanical cochlear models. An elastic bias of the basilar membrane and/or a mass loading of the cochlear duct account for the low-frequency hearing loss, diplacusis, and
OBJECTIVE
Excitotoxic and related inflammatory injury are implicated in the spiral ganglion degeneration seen with Meniere's disease and endolymphatic hydrops (ELH). Excitotoxicity is initiated with glutamate elevation and associated with downstream increases in reactive oxygen species resulting in
Several significant histopathological findings were noted in a case of sudden hearing loss in a patient with chronic lymphocytic leukemia. The major pathological findings were leukemic hemorrhage into both perilymphatic and endolymphatic spaces in the cochlear and vestibular systems, endolymphatic
Changes in hearing were studied in 145 ears (103 patients) with endolymphatic hydrops before and after an 8-week administration of isosorbide. Hearing improvement was observed in 57 (39.3%) of the 145 ears. These improvements showed a significant correlation with positive results in the glycerol
The cause(s) of the hearing impairment associated with Menière's disease are not understood but are undoubtedly associated with the inner ear endolymphatic hydrops. Two major hypotheses have been proposed and widely received: endolymphatic overpressure followed by leaky membranes and subsequently
OBJECTIVE
To report magnetic resonance imaging findings in a patient with an SLC26A4 gene mutation who had low-frequency sensorineural hearing loss.
METHODS
A 13-year-old girl had bilateral and symmetric low-frequency sensorineural hearing loss. Upon genetic testing, a heterozygous c.1105A > G
The purpose of this study was to investigate the existence of endolymphatic hydrops (EH) in affected and unaffected ears in patients with unilateral sensorineural hearing loss (SNHL) using contrast-enhanced magnetic resonance imaging (MRI), and to evaluate the significance of EH in various
The purpose of this study was to investigate the presence of endolymphatic hydrops (EH) in both affected and unaffected ears of patients with pantonal unilateral idiopathic sudden sensorineural hearing loss (ISSNHL) using three-dimensional fluid-attenuated inversion recovery magnetic resonance
OBJECTIVE
Acute low-tone sensorineural hearing loss (ALHL) has been reported to be associated with endolymphatic hydrops (EHs). However, evaluation of the size of the endolymphatic space has not been reported. We attempted to visualize EH in ALHL using magnetic resonance imaging
Endolymphatic hydrops (ELH), hearing loss and neuronal degeneration occur together in a variety of clinically significant disorders, including Meniere's disease (MD). However, the sequence of these pathological changes and their relationship to each other are not well understood. In this regard, an
OBJECTIVE
Endolymphatic hydrops (ELH) is an important histopathological hallmark of Ménière's disease. Experimental data from human temporal bones as well as animal models of the disorder have generally failed to determine the mechanism by which ELH or related pathology causes hearing loss. Hair
