Prognosis of asymptomatic endolymphatic hydrops in healthy volunteers: A five-year cohort study. [PDF]

Laryngoscope Investig Otolaryngol
Approximately 7% of healthy subjects showed asymptomatic EH by means of the inner ear MRI. Out of these subjects, 25.0% have kept EH and subsequently developed to be typical types of Meniere's disease within the next 5 years. Abstract Background This study aimed to clarify the prognosis of asymptomatic endolymphatic hydrops (EH) in healthy volunteers ...

The Auditory Nerve Overlapped Waveform (ANOW) Detects Small Endolymphatic Manipulations That May Go Undetected by Conventional Measurements [PDF]

Frontiers in Neuroscience, 2017
Electrocochleography (ECochG) has been used to assess Ménière's disease, a pathology associated with endolymphatic hydrops and low-frequency sensorineural hearing loss. However, the current ECochG techniques are limited for use at high-frequencies only (≥

A hidden pathophysiology of endolymphatic hydrops: case report of a patient with spontaneous intracranial hypotension presenting with sudden sensorineural hearing loss with vertigo [PDF]

Frontiers in Neurology
Spontaneous intracranial hypotension (SIH) is characterized by decreased cerebrospinal fluid (CSF) volume due to leakage through the dural membrane. We present the case of a patient with SIH manifested by fluctuating low-frequency hearing loss, tinnitus,

Endolymphatic hydrops and cochlear synaptopathy after noise exposure are distinct sequelae of hair cell stereociliary bundle trauma [PDF]

Scientific Reports
Endolymphatic hydrops, increased endolymphatic fluid within the cochlea, is the key pathologic finding in patients with Meniere’s disease, a disease of episodic vertigo, fluctuating hearing loss, tinnitus, and aural fullness.

Magnetic resonance imaging of endolymphatic hydrops: a comparison of methods with and without gadolinium-based contrast agent administration. [PDF]

Nagoya J Med Sci, 2023
In the evaluation of endolymphatic hydrops (EH) using magnetic resonance (MR) imaging, hybrid of reversed image of positive endolymph signal and native image of perilymph signal multiplied with heavily T2-weighted MR cisternography (HYDROPS-Mi2) imaging ...

Pathological significance and classification of endolymphatic hydrops in otological disorders. [PDF]

Nagoya J Med Sci, 2022
We summarize the presence of endolymphatic hydrops (EH) in otological disorders evaluated with magnetic resonance imaging (MRI) of temporal bones, and propose a classification of EH based on its pathological significance.

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

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

Is endolymphatic hydrops, as detected in MRI, a truly cochleocentric finding? [PDF]

Frontiers in Neurology
IntroductionThe most common histopathological finding in Ménière’s disease (MD) is endolymphatic hydrops (EH), which involves the dilation of the membranous labyrinth. The direct relationship between EH and MD is debated, although EH plays a crucial role

Consensus on MR Imaging of Endolymphatic Hydrops in Patients With Suspected Hydropic Ear Disease (Meniere) [PDF]

Frontiers in Surgery, 2022
Endolymphatic hydrops (EH) is considered the histological hallmark of Meniere's disease. Visualization of EH has been achieved by special sequences of inner ear magnetic resonance imaging (MRI) with a gadolinium-based contrast agent via intravenous or ...

Correlation of clinical parameters with endolymphatic hydrops on MRI in Meniere's disease [PDF]

Frontiers in Neurology, 2022
A clinical diagnosis of Ménière's disease (MD) is made based on medical history and audiometry findings. The 1995 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines requires histopathological confirmation of endolymphatic ...
