Cognitive Improvement After Cochlear Implantation

with Severe or Profound Hearing Impairment

HEARRING is always delighted to share new publications co-authored by the members of our group. It gives us an opportunity not only to spread the latest research outcomes, but also to inspire more prospective studies in the field of auditory science. The theme of our latest research paper is Cognitive Improvement after Cochlear Implantation in Older Adults with Severe or Profound Hearing Impairment. It has been published in the Journal of Ear & Hearing this year. The nature of the study design is truly exceptional, being prospective, longitudinal, controlled and multicenter.

The study involves such prominent HEARRING members, as Griet Mertens, Vedat Topsakal, Paul Van de Heyning, Vincent Van Rompaey, Miryam Calvino, Javier Gavilán, Piotr Henryk Skarżyński, Henryk Skarżyński, Christopher Raine, Dayse Tavora-Vieira, Roberta Marino, Aanand Acharya and Luis Lassaletta

According to the results of the study, improvements of the overall cognitive functioning and attention were observed after cochlear implantation in the intervention group. Moreover, significant positive effects of cochlear implantation on sound quality and self-perceived hearing outcomes were found in the intervention group. However, older CI users did not, in terms of cognition, bridge the performance gap with adults with normal hearing after one year of CI use. The fact that experienced, older CI users still present subnormal cognitive functioning may highlight the need for additional cognitive rehabilitation in the long term after implantation.

COVID-19 section

covid19 pandemic HEARRING

We decided to take initiative based on the current affairs and launch a new extremely important section about COVID-19. We believe that we all face this crisis together; and by pooling collective knowledge worldwide, we can progress faster in the process of conquering the virus. Therefore, HEARRING Group would like to once again bring attention to our two latest online events regarding the topics of “Setting new standards in clinical practices in the COVID-19 era” and “Audiology services during COVID-19”. Moreover, following the online round table discussion on the matter of “Audiology services during COVID-19”, experts all over the world took part in a survey on the subject. The findings are available in our COVID-19 section. Additionally, HEARRING picked the most relevant COVID-19 publications resonating through the field of auditory science.

Setting New Standards in COVID-19 Era

Round Table Discussion Covid Hearring


Numerous events have been cancelled all around the world due to the spread of COVID-19. However, HEARRING network members found a way to stay connected and maintain the co-active spirit even in those challenging times. An online round table discussion took place on May 23rd focusing on the extremely relevant topic of “Setting New Standards in Clinical Practice in the COVID-19 Era”. The discussion was moderated by our renowned expert Prof. Mohan Kameswaran and the board of speakers included such outstanding professionals as Prof. Wolf-Dieter Baumgartner, Prof. Joachim Müller, Prof. Javier Gavilán Bouzas, Prof. Vedat Topsakal, Prof. Vlad Kuzovkov and Prof. Manoj Manikoth.

As a result, the following has been conveyed: Cochlear Implant surgery is not an elective surgery. In some cases it’s an emergency surgery. For example, in the case of neuro-linguistic emergencies, when children are suffering from bilateral severe to profound deafness in the timeframe of high plasticity of the brain, the surgery shall not be delayed for more than one month. See below, to join the full event and to find out more about the main conclusions in the picture gallery.

Recap Würzburg 2020

Hearring members Würzburg

All of you had a chance to see the invitational post to this year’s 32nd course on microsurgery of the ME & auditory implants in Würzburg, Germany on the 17-19th February 2020.

Now, exactly one month later, we would like to share with you a few prime moments of this outstanding event hosted by Prof. Dr. S. Dazert and Prof. Dr. Dr. h. c. R. Hagen. 

Incredibly enriching content of this course included live surgeries of Stapes, Tympanosplasty and Soundbridge as well as of Cholesteatoma, Revisions and CI plus skull-base surgery of auditory implants. 

Moreover, the introducing lectures were dedicated to the following topics:

  • Temporal Bone Preparation (by K. Rak)
  • Basics of Tympanoplasty (by R. Mlynski)
  • Surgical Treatment of Otosclerosis (by S. Dazert)
  • Surgical Treatment of Cholesteatoma (by S. Plontke)

Special lectures covered tips and tricks in Middle Ear Surgery (by J. Helms) as well as a hands-on temporal bone laboratory workshop , and last but not least the auditory implant lectures focused on bone conduction implants (by  J.Gavilán), active middle ear implants (by M. Zernotti), cochlear implants (A. Radeloff).

One of the highlights was definitely the HEARRING comprehensive lecture on the matter of the future of inner ear treatment (by H. Staecker) followed by another hands-on temporal bone laboratory workshop. 

To sum it up, the 32nd course on microsurgery of the ME & auditory implants in Würzburg was an overall success as this educating event contributed to more comprehensive, co-active, innovative surgical approaches.

On behalf of our HEARRING Team, we would like to thank all of the participants and organizers for making Würzburg event extraordinary.
