Deadline extension - Special Collection: "Advances in implantable hearing devices" - Call for papers
Submission deadline: September 15th , 2022
The objective of this special collection is to present the latest advances related to diagnostic audiological assessments necessary to indicate cochlear implantation, surgical approaches, rehabilitation as well as the latest technologies in implantable hearing devices, from the processor to the design of electrodes for implantable hearing aids.
Cochlear implants (CI) have proven to be the best option for rehabilitating severe and profound hearing loss in children and adults, providing better access to the acoustic environment and, especially, to speech.
The first trial using electrical stimulation of the auditory nerve was conducted in 1953 by Djourno and Eyries operated on a patient with chronic otitis media and facial paralysis. In 1970, William House, in California, reported that a deaf subject could perceive sound after receiving the first implant based on auditory nerve stimulation using a single electrode. Since then, CI technology has continuously advanced: in 1984, multichannel CIs were developed and speech processing strategies were progressively improved. At the beginning of the century, CIs were approved for use in children as well, and they are now considered the standard for treating profound congenital bilateral hearing loss. Based on clinical results, the audiological criteria for implantation have been progressively expanded to include adults with asymmetric hearing loss, unilateral deafness or high-frequency hearing loss ("ski slope audiograms"). In addition, children with disabilities in addition to hearing loss also can regain hearing through CI.
Today, new surgical techniques combined with new electrode developments and together with the great development of medical imaging allow to preserve better and better the delicate structures of the cochlea after cochlear implantation. In addition, speech rehabilitation methods have evolved, new coding strategies continue to be developed allowing the improvement of noise listening and localization for CI users. However, results with HF can vary significantly due to a wide variety of factors influencing performance. It is imperative to identify the factors responsible for this variability to maximize the benefits that will affect the CI user throughout their lifetime. Besides, implantable hearing devices ,such as bone-anchored hearing devices, middle-ear active implants , electro-acoustical stimulation or auditory brainstem implants, have emerged and showed their benefits in patients with specific types of hearing losses.
The set of articles published within the special collection "Advances in Implantable Hearing Devices" are expected to address different aspects, including:
- Surgical advances related to the implantation of these devices.
- Advances in the criteria of cochlear implantation.
- Advances in hardware and software, including new coding strategies.
- Benefits observed in terms of functional hearing and quality of life.
- Improvements in different aspects of auditory perception, such as speech intelligibility or sound localization, etc.
