Perilymphatic enhancement and endolymphatic hydrops: MRI findings and clinical associations.
Laryngoscope Investig Otolaryngol
October 2024
Department of Otorhinolaryngology Nagoya University Graduate School of Medicine Nagoya Japan.
Objective: In this study, we aimed to summarize magnetic resonance imaging (MRI) findings of perilymphatic enhancement (PE) and endolymphatic hydrops (EH) of the inner ear, which are associated with vestibular and cochlear symptoms.
Methods: We analyzed data on ears with definite Meniere's disease (MD), sensorineural hearing loss (SNHL), vertigo, and listening difficulties (LiD) from 508 ears of 254 patients who underwent contrast-enhanced 3-Tesla MRI between April 2021 and March 2023. We evaluated the degree of endolymphatic hydrops (EH), signal intensity ratios (SIRs) between the basal turns of the cochlea and cerebellum, and hearing levels for all ears.
Improvement of vertigo symptoms and acoustic power absorbance in cases with endolymphatic hydrops.

Article Synopsis
- The study examines the effects of middle ear pressure therapy (MEPT) on symptoms and endolymphatic hydrops (EH) in patients with Meniere's disease (MD) through MRI and acoustic power measurements.
- Eleven patients participated, showing improvements in vertigo scores after one year of MEPT, but most did not show significant changes in the severity of EH.
- Although EH severity did not improve significantly, there was an enhancement in acoustic power absorbance, suggesting that changes in inner ear pressure may influence vestibular symptoms even if EH remains unchanged.
Impact of endolymphatic hydrops on DPOAE in subjects with normal to mild hearing loss.

Department of Otorhinolaryngology Nagoya University Graduate School of Medicine Nagoya Japan.
Article Synopsis
- The study focuses on how increased endolymph volume affects the ear structure and may influence the distortion-product otoacoustic emissions (DPOAE) in patients with endolymphatic hydrops (EH).
- Researchers analyzed 403 patients with hearing or balance issues, comparing DPOAE responses and hearing levels to understand the relationship between EH and hearing ability.
- Results showed no correlation between DPOAE amplitude and EH presence, but indicated that patients with cochlear EH had better DPOAE responses, suggesting that changes in DPOAE may reflect early morphological changes in the inner ear.
Computed tomographic assessment of autologous fat injection augmentation for vocal fold paralysis.
Laryngoscope Investig Otolaryngol
December 2017
Department of Otorhinolaryngology Nagoya University Graduate School of Medicine Nagoya Japan.
Objective: To perform a quantitative computed tomography (CT) assessment of short- and long-term outcomes of autologous fat injection augmentation in patients with unilateral vocal fold paralysis.
Study Design: Retrospective case series.
Methods: Twelve patients who had undergone autologous fat injection augmentation for unilateral vocal fold paralysis in our hospital between 2011 and 2015 were enrolled in this study.
