Protective effect of edaravone against endolymphatic hydrops

, 2007
CONCLUSION: Our findings suggest that edaravone prevented the production of reactive oxygen species (ROS). Edaravone also delayed the formation of endolymphatic hydrops in guinea pigs, but had no effect on endolymphatic hydrops. OBJECTIVE: To analyse the

Endolymphatic hydrops in asymptomatic ears in unilateral Meniere's disease

, 2001
Objectives/hypothesis: the aim of our study was the objective assessment of endolymphatic hydrops in asymptomatic ears in unilateral Meniere's disease with a noninvasive electrophysiological test and investigation of significant clinical signs.

Comparison of the diagnostic value of 3 T MRI after intratympanic injection of GBCA, electrocochleography, and the glycerol test in patients with Meniere's disease [PDF]

, 2012
Conclusion. 3 T MRI after intratympanic injection of gadolinium-based contrast agent (GBCA) is more useful for the diagnosis of endolymphatic hydrops compared with the glycerol test and electrocochleography (ECoG).

Three-Dimensional Magnetic Resonance Imaging Reveals the Relationship Between the Control of Vertigo and Decreases in Endolymphatic Hydrops After Endolymphatic Sac Drainage With Steroids for Meniere's Disease

Frontiers in Neurology, 2019
Meniere's disease is a common disease, that presents with recurrent vertigo and cochlear symptoms. The pathology of Meniere's disease was first reported to involve endolymphatic hydrops in 1938. The endolymphatic sac is thought to have a role to keep the

Imaging Analysis of Patients With Meniere's Disease Treated With Endolymphatic Sac-Mastoid Shunt Surgery

Frontiers in Surgery, 2022
Objective: Endolymphatic sac surgery is effective in treating intractable Meniere's disease (MD), but the underlying mechanism is still unknown. Our study investigated the mechanism by which endolymphatic sac-mastoid shunt (EMS) surgery is effective in ...

Altered mapping of sound frequency to cochlear place in ears with endolymphatic hydrops provide insight into the pitch anomaly of diplacusis

Scientific Reports, 2021
A fundamental property of mammalian hearing is the conversion of sound pressure into a frequency-specific place of maximum vibration along the cochlear length, thereby creating a tonotopic map. The tonotopic map makes possible systematic frequency tuning

Predicting cochlear structural alterations from auditory function in age‐related hearing loss mice based on optical coherence tomography

Journal of Intelligent Medicine, EarlyView.
Abstract With global population aging, age‐related hearing loss has become a major public health concern. Understanding the relationship between auditory functional decline and cochlear structural degeneration is essential for early detection and precise intervention.

Effects of Glucocorticoids on the Inner Ear

Frontiers in Surgery, 2021
Hypothesis: Recently, several lines of evidence have suggested that the inner ear is under hormonal control. It is likely that steroids have some influence on the inner ear.Background: Many clinicians have been empirically using steroids for the ...

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

The Laryngoscope, EarlyView.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.

Endolymphatic hydrops after total dissection or cauterization of the distal portion of the endolymphatic sac

, 1996
In this study, a more subtle animal model of Meniere's disease is investigated by damaging the distal portion of the endolymphatic sac by dissection or cauterization to produce mild dysfunction of endolymphatic outflow.
