Ultrasound‐Powered, Battery‐Free Implants via Triboelectric Energy Harvesting

Advanced Materials Technologies, EarlyView.
Ultrasound‐driven triboelectric nanogenerators (US‐TENGs) present a promising approach to battery‐free implants by combining body‐safe ultrasound with the material and structural versatility of TENGs. This review categorizes current US‐TENG research into long‐term and transient short‐term applications and discusses key challenges in materials, device ...

A case of cochlear-facial dehiscence revealed after bilateral cochlear implants

Radiology Case Reports
The cochlear implant is an implanted auditory prosthesis that can restore severe and profound hearing loss. About 20% of patients with congenital sensorineural hearing loss have a malformation of the inner ear.

Classification and Current Management of Inner Ear Malformations

Balkan Medical Journal, 2017
Morphologically congenital sensorineural hearing loss can be investigated under two categories. Majority of the congenital hearing loss (80%) are membranous malformations. Here the pathology involves inner ear hair cells.

Possibilities of Inner Ear Barrier Models for Otologic Drug Development

Advanced Therapeutics, EarlyView.
This review examines innovative organ chip models that reconstruct critical inner ear barriers, addressing a fundamental challenge in otologic drug development: the limited understanding of pharmaceutical behavior across these complex barriers. By replicating these barriers, the advanced models offer promising alternatives to traditional testing ...

Development of a feline model for preclinical research of a new translabyrinthine auditory nerve implant

Frontiers in Neuroscience
Cochlear implants are among the most successful neural prosthetic devices to date but exhibit poor frequency selectivity and the inability to consistently activate apical (low frequency) spiral ganglion neurons. These issues can limit hearing performance

Cochlear Implantation in Patient with Cochlear Nerve Deficiency: A Case Report

The Journal of International Advanced Otology, 2019
Abstract Diagnostic imaging methods are very important for patients with bilateral sensourinoural hearing loss. Magnetic resonance imaging (MRI) is able to demonstrate the vestibulocochlear nerve and facial nerve in the internal acoustic canal. Also computed tomography can be helpful to determination of the deficiency of the cochlear nerve.
