Restoring Hearing After Resection of Vestibular Schwannoma by Cochlear Nerve Preservation and Cochlear Implantation: Long-Term Follow-Up of Two Cases

open access: yesB-ENT
Hearing outcomes of two cases of growing sporadic vestibular schwannoma, resected via a translabyrinthine approach with simultaneous cochlear implantation are reported.

The role for cochlear implants in microtia and congenital aural atresia: A case report and a review of literature

open access: yesProceedings of Singapore Healthcare, 2023
Sensorineural hearing loss resulting from microtia and aural atresia is rare due to different embryologic origins of the external and inner ear. Consequently, cochlear implants are seldom performed in patients with microtia and/or aural atresia.

A ratchet mechanism for amplification in low-frequency mammalian hearing

open access: yes, 2010
The sensitivity and frequency selectivity of hearing result from tuned amplification by an active process in the mechanoreceptive hair cells. In most vertebrates the active process stems from the active motility of hair bundles.

Perilymph pharmacokinetics of marker applied through a cochlear implant in guinea pigs [PDF]

open access: yes, 2017
Patients undergoing cochlear implantation could benefit from a simultaneous application of drugs into the ear, helping preserve residual low-frequency hearing and afferent nerve fiber populations.

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Intracochlear Auditory Nerve Monitoring and Cochlear Implantation After Total Resection of a Vestibular Schwannoma: Case Report

open access: yesB-ENT
The aim is to present a case of cochlear implantation (CI) after vestibular schwannoma (VS) resection and intracochlear auditory nerve monitoring. The case of a 53-year-old man with left-sided iatrogenic dehiscence of the posterior semicircular canal ...

Measurements From Ears With Endolymphatic Hydrops and 2-Hydroxypropyl-Beta-Cyclodextrin Provide Evidence That Loudness Recruitment Can Have a Cochlear Origin

open access: yesFrontiers in Surgery, 2021
Background: Loudness recruitment is commonly experienced by patients with putative endolymphatic hydrops. Loudness recruitment is abnormal loudness growth with high-level sounds being perceived as having normal loudness even though hearing thresholds are

The Impact of Age and Duration of Cochlear Implant in a Congenital Deaf Population: An ERP Study [PDF]

open access: yes, 2016
Objective: It is well known that patients with Cochlear Implant (CI) have a large inter-individual variability in linguistic and auditory performances. This can be related to individual auditory processing abilities and integrity of auditory system from ...

Degeneration in the cochlear nerve of the rat following cochlear lesions

open access: yesBrain Research, 1988
Left unilateral cochlear lesions were performed on 26 albino rats at 1.5 months of age. After survival times ranging from 1 h to 6 months, the animals were perfused via the aorta with mixed aldehydes. Blocks including the cochlear nerves were removed, embedded in Araldite, sectioned in a plane transverse to the longitudinal axis of the nerve, and ...

Targeted Local Delivery via Fiber‐Embedded Flexible Microchannels Integrated with Film‐Based Implantable Probes

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, a fiber‐embedded drug delivery channel for implantable microprobes, demonstrating the first functional drug delivery system using flexible LCP‐based probes, is developed. The design incorporates fibers for site‐selective drug delivery and electrical functions. The utilization of monolithic thermal bonding simplifies fabrication.
