In addition, the earlier a child is implanted with a cochlear device and the longer he or she wears the device, the better overall quality of life the child reports and the more successful the child is in school, according to the findings, published in the February issue of Otolaryngology – Head and Neck Surgery.
"Wearing cochlear implants doesn't seem to create greater psychosocial problems overall for their users," said Dr. Betty Loy, clinical research manager in the Department of Otolaryngology – Head and Neck Surgery and lead author of the study.
Cochlear implants are small electronic devices that are surgically implanted in the inner ear and activated by another device worn outside the ear. They bypass damaged or diseased parts of the ear by directly stimulating the auditory nerve, which is connected to the brain.
Researchers surveyed 88 families of children with cochlear implants, including parents. They then compared the responses with normal-hearing peers in two age groups: 8- to 11-year-olds and 12- to 16-year-olds. Quality-of-life factors assessed included physical, mental and emotional health; self-esteem; relationships with family and friends; and school performance.
Researchers found that younger cochlear implant recipients rated overall quality of life more positively than those who were in the older age group, although that may simply reflect greater adolescent angst, Dr. Loy said.
The survey results also confirmed that parents are generally accurate in gauging their child's perception of quality of life, although they slightly overestimated the satisfaction levels at school for older children.
According to the Food and Drug Administration, approximately 188,000 people worldwide have received cochlear implants as of 2009. In the U.S., roughly 41,500 adults and 25,500 children have received them.
The study was a joint effort by researchers at UT Southwestern, UT Dallas and the Dallas Cochlear Implant Program. Other UT Southwestern authors involved in the study were Dr. Peter Roland, chairman of otolaryngology – head and neck surgery; Liyue Tong, biostatistical consultant; and Dr. Emily Tobey, clinical professor of otolaryngology – head and neck surgery.
The research was funded in part by a grant from the National Institutes of Health and by the Med-El Corp.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
