Asymmetrically severe internal auditory canal hypoplasia: A case report. [PDF]

, 2020
We present a case of an otherwise healthy 20-month-old with congenital sensorineural hearing loss. CT and MR imaging demonstrated bilateral asymmetrically severe hypoplasia of the internal auditory canals and vestibulocochlear nerves.

Multicargo Porous Cochlear Electrode Coating for Antifibrosis After Cochlear Implantation

Advanced Science, EarlyView.
This study presents a novel porous drug‐loading coating for cochlear electrodes, utilizing MA‐PDMS infused with GelMA hydrogel containing dexamethasone and MXene nanoparticles. The coating enhances biocompatibility, enables sustained drug release, reduces fibrosis, and preserves residual hearing post‐CI.

Validation of image-guided cochlear implant programming techniques [PDF]

arXiv, 2019
Cochlear implants (CIs) are a standard treatment for patients who experience severe to profound hearing loss. Recent studies have shown that hearing outcome is correlated with intra-cochlear anatomy and electrode placement. Our group has developed image-guided CI programming (IGCIP) techniques that use image analysis methods to both segment the inner ...

Micro‐Coil Neuromodulation at Single‐Cell and Circuit Levels for Inhibiting Natural Neuroactivity, Neutralizing Electric Neural Excitation, and Suppressing Seizures

Advanced Science, EarlyView.
Micromagnetic stimulation (µMS) offers a precise method for neural inhibition, complementing existing neuromodulation techniques. Using an implantable micro‐coil device, µMS selectively suppresses cortical activity with high spatial resolution. It effectively counteracts micro‐electrode stimulation and reduces seizure amplitude, highlighting its ...

Endoscopic vs. volumetric OCT imaging of mastoid bone structure for pose estimation in minimally invasive cochlear implant surgery [PDF]

arXiv, 2019
Purpose: The facial recess is a delicate structure that must be protected in minimally invasive cochlear implant surgery. Current research estimates the drill trajectory by using endoscopy of the unique mastoid patterns. However, missing depth information limits available features for a registration to preoperative CT data.

Intraoperative electrocochleographic characteristics of auditory neuropathy spectrum disorder in cochlear implant subjects [PDF]

, 2017
Auditory neuropathy spectrum disorder (ANSD) is characterized by an apparent discrepancy between measures of cochlear and neural function based on auditory brainstem response (ABR) testing.

Visualization of the Spiral Ganglion Neuron in Vivo Using a Novel 177Lu Nuclear Molecule Label

Advanced Science, EarlyView.
The study developed and validated a radionuclide‐labeled anti‐VGLUT1 antibody probe for the first nuclear imaging of cochlear spiral ganglion neurons (SGNs) in vivo. This approach may provide aid in screening candidates suitable for CI surgery by quantifying the number of surviving SGNs, and predicting the potential for postoperative hearing ...

A novel method for obtaining a better quality speech signal for cochlear Implants using kalman with drnl and ssb technique [PDF]

Advanced Computing: An International Journal ( ACIJ ), 3(4), 71 - 75. 2012, 2012
Cochlear implant devices are known to exist since a long time. The purpose of the present work is to develop a speech algorithm for obtaining robust speech. In this paper, the technique of cochlear implant is first introduced, followed by discussions of some of the existing techniques available for obtaining speech.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Cochlear implant and tinnitus–a meta-analysis

Brazilian Journal of Otorhinolaryngology, 2021
Introduction: Tinnitus is a frequent symptom in cochlear implant patients, often reported as persistent and disabling in implant candidates. Tinnitus is rarely considered in the preoperative evaluation of patients who are eligible for cochlear ...
