Direct administration of 2-Hydroxypropyl-Beta-Cyclodextrin into guinea pig cochleae: Effects on physiological and histological measurements. [PDF]

PLoS ONE, 2017
2-Hydroxypropyl-Beta-Cyclodextrin (HPβCD) can be used to treat Niemann-Pick type C disease, Alzheimer's disease, and atherosclerosis. But, a consequence is that HPβCD can cause hearing loss. HPβCD was recently found to be toxic to outer hair cells (OHCs)

The Estimation of the Time Constant of the Human Inner Ear Pressure Change by Noninvasive Technique

Modelling and Simulation in Engineering, 2009
We propose a noninvasive method to estimate the time constant. The calculation of this factor permits us to understand the pressure variations of the inner ear and also predict the behavior of the flow resistance of the cochlear aqueduct.

Padrão radiológico da otosclerose coclear. Estudo por TC de 14 doentes.

Acta Médica Portuguesa, 1994
In this review of cochlear otosclerosis 14 cases were studied by CT scan aiming to establish a densitometric pattern of the capsular foci and relating it to the hearing and vestibule dysfunctions.

Extending the glymphatic system beyond the brain: The Cochlear aqueduct as a neuroimmune gateway to the inner ear

Neurobiology of Disease
The cochlear aqueduct, located within the temporal bone, forms a narrow connection between the cerebrospinal fluid (CSF) in the subarachnoid space and the perilymph of the scala tympani in the inner ear.

Inner ear malformation

Listy klinicke logopedie, 2020
Inner ear malformation comprises a broad group of disorders, the main symptom of which is hearing loss. The disorder occurs during the embryonic development of the auditory system. Only about 20 % of malformations can be diagnosed radiologically. Hearing

A morphometric study of the structures bordering the infra-cochlear corridor – Relevant for endoscopic/microscopic ear surgery

Journal of Otology, 2018
Application of surgical endoscope, used alone or in combination with the surgical microscope, for the operative management of ear and temporal bone conditions may allow improved access and clearance of disease.

Complications of Cochlear Implant Surgery in Low‐ and Middle‐Income Countries: A Systematic Review

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Hearing loss disproportionately affects low‐ and middle‐income countries (LMICs). Recent advances in cochlear implant surgery have benefitted patients globally, but the risk of complications in LMICs may be heightened due to social and structural factors.

Investigation of Mechanisms in Bone Conduction Hyperacusis With Third Window Pathologies Based on Model Predictions

Frontiers in Neurology, 2020
A lumped element impedance model of the inner ear with sources based on wave propagation in the skull bone was used to investigate the mechanisms of hearing sensitivity changes with semi-circular canal dehiscence (SSCD) and alterations of the size of the
