Deaf children under two years old can hear

29.11.2002


Thanks to the cochlear implant deaf children under two years old can express and understand properly the language. Those are the results obtained by the University Clinic of the University of Navarre.



The University Clinic of Navarre is a pioneer in cochlear implant. This technique replaces the ear with a system that stimulates the hearing nerve electrically.

The programme of cochlear implant started in 1989 and one year later was done the first implant. This first implant was made to an 11 years old girl, and in 1992 it could be made for the first time to a 2 years old child. Nowadays, implants are also done to children of 10-12 months old successfully.


Since the application of this programme, 356 implants have been done to people between 9 months and 82 years old. Two third of the implants were done to children. In fact, 80 % of the cases of deafness can be detected at birth, and the earlier the implant is done the better are the results. In the case of adults that lose audition after learning the language, % 80 of them can recover the capacity to recognise words without reading the lips. In case of children, the percentage increases up to 95 %, unless they do not have any other disease.

Technique

Implants of children under two years are different comparing to implants done in other patients. The position is different and the size is also smaller. That makes it a meticulous operation. However, thanks to the improvement of the technique and the fact that children bones are very flexible, the operation only takes 45 minutes. Then, the implant is activated and programmed, because children, as they are too young, cannot help activating the implant.

Some other progresses

Until recent years, cochlear implants were only done to people with serious hearing loss. But now, the University Clinic has extended the implants to people that do not get successful results with audiphones. That way, anyone who has restricted his or her private and social life due to serious hearing loss, has now a new option available.

In addition, the department of Otorhynolaryngology has set up a bilateral implants programme to promote the normalisation of the hearing process. Hearing quality depends on the binaural perception. With two ears, we can know from which direction a sound comes from, in noise areas the hearing is better and the shadow effect of the head disappears. Furthermore, in case of neuronal plasticity of hearing, bilateral implants can be very useful.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
