The Anatomy and Anatomical Variations of the Round Window Prechamber and Their Implications on Cochlear Implantation: An Anatomical, Imaging, and Surgical Study

International Archives of Otorhinolaryngology, 2020
Introduction Over the last decades, there has been a tremendous increase in the number of cochlear implant recipients and, consequently, there is a recent increase of interest in the proper understanding of the anatomy of the round window (RW), which is ...

Patient Experience of Undergoing MRI With a New Active Transcutaneous Bone‐Anchored Hearing Implant

The Laryngoscope, EarlyView.
Active transcutaneous bone‐anchored hearing implants belong to a class of devices that may pose challenges in magnetic resonance imaging (MRI) settings. In this prospective study, all MRI scans in patients (n = 15) with the Sentio Ti implant were completed without complications, and patients reported generally positive experiences with low levels of ...

Multicenter Study Results on Expanded Indications in Med‐EL Pediatric Cochlear Implant Population

The Laryngoscope, EarlyView.
ABSTRACT Objectives To demonstrate safety and efficacy of MED‐EL cochlear implants (CIs) in children aged < 12 months and in children aged 12–71 months with residual hearing. Methods This was a multicenter, nonrandomized, single‐subject, repeated‐measures study with prospective (N = 38; 26 < 12 months of age) and retrospective (N = 209; 70 < 12 months ...

COCHLEAR IMMUNE INJURY FOLLOWING DIRECT ANTIGEN CHALLENGE TO THE ENDOLYMPHATIC SAC

Nippon Jibiinkoka Gakkai Kaiho, 1993
Following direct KLH antigen challenge to the endolymphatic sac (e. sac) in guinea pigs, degeneration of the cochlea was examined histologically by light microscopy. Degeneration was seen in 21 out of 140 animals presensitized systemically from day 1 to 5 weeks post secondary KLH challenge to the e. sac.

The Incidence of Sensorineural Hearing Loss Diagnoses in People with and without Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) and sensorineural hearing loss (SNHL) are both prevalent conditions among older adults. Although increasing number of studies have investigated SNHL as a risk factor for PD, it is not well known how diagnosed PD affects the likelihood of SNHL diagnosis.

Joint Risk Factor Combinations with Additive Interaction Increase the Risk of Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Combined effects of multiple risk factors on incident late‐onset Parkinson's disease (PD; LOPD) remain poorly characterized. Objective The objective of this study was to quantify the impact of joint risk exposures and estimate the contribution of potentially modifiable factors to incident LOPD risk.

Nfatc4 Deficiency Attenuates Ototoxicity by Suppressing Tnf-Mediated Hair Cell Apoptosis in the Mouse Cochlea

Frontiers in Immunology, 2019
The loss of sensory hair cells in the cochlea is the major cause of sensorineural hearing loss, and inflammatory processes and immune factors in response to cochlear damage have been shown to induce hair cell apoptosis.

Complications of Cochlear Implant Surgery in Low‐ and Middle‐Income Countries: A Systematic Review

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Hearing loss disproportionately affects low‐ and middle‐income countries (LMICs). Recent advances in cochlear implant surgery have benefitted patients globally, but the risk of complications in LMICs may be heightened due to social and structural factors.
