The Listening Network and Cochlear Implant Benefits in Hearing-Impaired Adults.

Older adults with mild or no hearing loss make more errors and expend more effort listening to speech. Cochlear implants (CI) restore hearing to deaf patients but with limited fidelity. We hypothesized that patient-reported hearing and health-related quality of life in CI patients may similarly vary according to age.

Surgical Solution for the Transformation of the Percutaneous Bone Anchored Hearing Aid to a Transcutaneous System in Complicated Cases.

Bone-anchored hearing aids (BAHAs) have been used for multiple types of hearing loss both in pediatric and adult cases. In the last decades, the percutaneous BAHA® Connect System (Cochlear Ltd., Sydney, Australia) was replaced by the fully implanted transcutaneous, magnet-based BAHA® Attract System (Cochlear Ltd.

[Tracheostomy during novel corona virus pandemic].

Recently, 6 percent of COVID-19 patients required prolonged mechanical ventilation due to severe respiratory failure. Early tracheostomy prevents the risk of postintubation upper airway stenosis. In the pandemic, all surgical interventions that generate aerosol increase the risk of contamination of the medical staff, for which reason the "traditional" indications of tracheostomy have to be revised.

Review of electrode placement with the Slim Modiolar Electrode: identification and management.

Background - Several cochlear implant recipients experience functionality loss due to electrode array mal-positioning. The application of delicate perimodiolar electrodes has many electrophysiological advantages, however, these profiles may be more susceptible to tip fold-over. Purpose - The prompt realization of such complication following electrode insertion would be auspicious, thus the electrode could be possibly repositioned during the same surgical procedure.

[Dimensions of the human temporal bone that are relevant to cochlear implantation surgery in infants and toddlers. ].

Early cochlear implantation enables prelingual deaf individuals to become full members of the hearing society. Although early diagnostics are widely accessible and enable early rehabilitation, implant surgery often may be delayed due to a candidate's young age. The authors' objectives were to determine the anatomical parameters of the pediatric and adult temporal bone that are relevant to cochlear implantation and to ascertain the differences between them in order to assess whether the anatomical differences could influence the surgical technique and the timing of surgery.

[The distance from the modiolus of perimodiolar electrode arrays of cochlear implants. ].

The cochlear implants vary in electrodes in terms of length, width and proximity to the modiolus. The precurved electrode arrays could be placed closer to the modiolus and the ganglion cells compared to straight electrodes. The two types of electrode arrays provide different electrophysiological characteristics; however, proximity to the modiolus may lead to better hearing performance.

[Possibilities for residual hearing preservation with Nucleus CI532 Slim Modiolar electrode array. Case report].

During the rehabilitation of hearing-impaired patients, the preservation of residual acoustic hearing following cochlear implantation by minimizing the implantation trauma allows for improved hearing performance. To achieve this, minimally invasive, soft surgery methods and thinner, atraumatic electrodes were required. In our present study, we reported a case where Cochlear® Nucleus CI532 Slim Modiolar electrode was implanted in a patient with residual hearing.
