Method to estimate the basal turn length in inner ear malformation types

open access: yesScientific Reports, 2023
The mathematical equations to estimate cochlear duct length (CDL) using cochlear parameters such as basal turn diameter (A-value) and width (B-value) are currently applied for cochleae with two and a half turns of normal development.

The relationship of the round window membrane to the cochlear aqueduct shown in three-dimensional imaging [PDF]

open access: yes, 2005
The round window membrane and cochlear aqueduct complex in the guinea pig are reconstructed with 3D-imaging, using orthogonal plane fluorescence optical sectioning (OPFOS).

Estudo por tc de 17 casos de anomalia congénita coclear. Tentativa de relação embriológica e anátomo-funcional.

open access: yesActa Médica Portuguesa, 1993
In this review of cochlear malformations, 17 cases were studied by CT scan (high resolution-target program) including 10 males and 7 females. The anomaly was bilateral in 12 cases and unilateral in 7 (the latter included 2 Mondini type aplasias and one ...

A possible third window for bone conducted hearing: Cochlear aqueduct vs. vestibular aqueduct [PDF]

open access: yes, 2015
A third window, which is another cochlear fluid pathway different from the oval window and round window, is considered to be a significant factor in bone-conducted hearing.

Relationship Between the Cochlear Aqueduct and Internal Auditory Canal: Surgical Implications for Transcanal Transpromontorial Approaches to the Lateral Skull Base. [PDF]

open access: yes, 2020
HYPOTHESIS The cochlear aqueduct (CA) is subject to considerable anatomical variability. We hypothesize a topographical relationship between the CA and the internal auditory canal (IAC). BACKGROUND The CA represents the lower limit of dissection

Computed tomographic 3D analysis of the cochlear aqueduct—potential and limitations of clinical imaging [PDF]

open access: yes, 2023
Background: The cochlear aqueduct (CA), which connects the scala tympani and the subarachnoid space, and its accompanying structures appear to have a significant relevance during cochlear implantation and an accurate visualization in clinical imaging is ...

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

open access: yesPLoS 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)

Cochlear aqueduct flow resistance depends on round window membrane position in guinea pigs [PDF]

open access: yes, 2004
The resistance for fluid flow of the cochlear aqueduct was measured in guinea pigs for different positions of the round window membrane. These different positions were obtained by applying different constant pressures to the middle car cavity. Fluid flow
