Does the audiogram shape influence the intracochlear recording of Electrocochleography during and after cochlear implantation?
Front Neurosci
January 2025
Department of Otorhinolaryngology, Hannover Medical School, Hanover, Germany.
During cochlear implant (CI) surgery, it is desirable to perform intraoperative measurements such as Electrocochleography (ECochG) to monitor the inner ear function and thereby to support the preservation of residual hearing. However, a significant challenge arises as the recording location of intracochlear ECochG via the CI electrode changes during electrode insertion. This study aimed to investigate the relationships between intracochlear ECochG recordings, the position of the recording contact within the cochlea relative to its anatomy, and the implications for frequency and residual hearing preservation.

Background And Objectives: Jugular paragangliomas (JPG) pose a surgical challenge because of their vascularity and complex location. Stereotactic radiosurgery (SRS) offers a minimally invasive management for patients with JPG. Our aim was to evaluate outcomes of Gamma Knife radiosurgery (GKRS) for the treatment of JPG over the long term.

Department of Otolaryngology at Unfallkrankenhaus Berlin, Charité Medical School, University of Berlin, 12683 Berlin, Germany.
Background: Previous studies have shown that multiple post-traumatic irradiations of the cochlea with near-infrared light (NIR) can significantly reduce noise-induced hearing loss. However, a single NIR pre-treatment was shown to have the same effect. Extending the pre-treatment time did not result in any further reduction in hearing loss.

Nat Commun

Department of Pharmacology and Therapeutics, University of Florida, Gainesville, FL, USA.
Assembly of actin-based stereocilia is critical for cochlear hair cells to detect sound. To tune their mechanosensivity, stereocilia form bundles composed of graded rows of ascending height, necessitating the precise control of actin polymerization. Myosin 15 (MYO15A) drives hair bundle development by delivering critical proteins to growing stereocilia that regulate actin polymerization via an unknown mechanism.
