Estimation of outer-wall length in optimizing cochlear implantation in malformed inner ears

Scientific Reports
Estimation of cochlear length is gaining attention in the field of cochlear implants (CIs), mainly for selecting of CI electrode lengths. The currently available tools to estimate the cochlear duct length (CDL) are only valid for normal inner anatomy ...

Exocytosis at mammalian vestibular ribbon synapses shows a high-order Ca2+ dependence and does not require synaptotagmin-4

, 2018
Inner ear sensory synapses faithfully transduce information over a wide range of stimulus intensities for prolonged periods of time. The efficiency of such demanding and stringent exocytotic activity depends on the presence of specialised presynaptic ...

MRI macrophage detection in a guinea pig model of inner ear inflammation

, 2011
Inner ear inflammation is considered a major contributor to the development of hearing loss. Yet most information is derived from acute animal studies and little is known about the progression of inflammatory disease in the living inner ear.

Congenital Middle Ear Malformation with Common Deafness Gene Mutation Analysis: A Review of 813 Profound Sensorineural Hearing Loss Child Patients

, 2020
Deafness gene variants play a key role in inner ear malformations. However, the relationship between congenital middle ear malformations and common deafness genes (GJB2, SLC26A4, and mtDNA) in profound sensorineural hearing loss (SNHL) child patients ...

NOX3-Targeted Therapies for Inner Ear Pathologies

, 2015
Inner ear pathologies are associated with major morbidity and loss of life quality in affected patients. In many of these conditions, production of reactive oxygen-species (ROS) is thought to be a key pathological mechanism.
