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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
