To evaluate the outcome of cochlear implantation in young children relation to age at implantation.A retrospective longitudinal and cross-sectional analysis pediatric implant patients.All with congenital deafness who underwent before 6 years (n = 48 for n 70 analysis)All received a multichannel implant.Categories Auditory Performance (CAP) score integration into mainstream school system.For all children, CAP increased after implantation. Implantation beyond 4 hardly ever resulted normal...
The programming of CIs is essential for good performance. However, no Good Clinical Practice guidelines exist. This paper reports on the results an inventory current practice worldwide. A questionnaire was distributed to 47 CI centers. They follow 47600 recipients in 17 countries and 5 continents. were discussed during a debate. Sixty-two percent verified through individual interviews following months. Most centers (72%) participated cross-sectional study logging consecutive fitting sessions...
One of the major complaints people with a single-sided deafness is inability to localize sound sources. Evidence suggests that subjects hearing loss can benefit from use cochlear implant (CI) in localization. This study aimed determine effect CI on localization ability unilaterally deafened subjects.Sixteen adult postlingual unilateral deafness, fitted deaf side, were included this study. The auditory speech sounds evaluation (A§E) test was used (binaural) and off (monaural). root mean...

Objective To evaluate the long-term effect of intracochlear steroid deposition on electrode impedance in patients with cochlear implants. Study Design A retrospective study was carried out comparing impedances implant electrodes and without a single application steroids cochlea. Patients Ninety two implanted children an average age 5 years (range, 0.7 to 16 years) were divided four groups according type use or not. In addition, five who required reimplantation are reported. Main Outcome...
An intelligent agent, Fitting to Outcomes eXpert, was developed optimize and automate Cochlear implant (CI) programming. The current article describes the rationale, development, features of this tool.Cochlear fitting is a time-consuming procedure define value subset available electric parameters based primarily on behavioral responses. It comfort-driven with high intraindividual interindividual variability both respect patient clinician. Its validity in terms process control can be...
Contralateral suppression of transient evoked otoacoustic emissions (TEOAEs) can be used in a clinical set-up using procedure based on unique and robust parameter to quantify the magnitude for subject.TEOAEs suppressed by delivering contralateral white noise (WN). This is thought mediated via efferent nerve fibers that innervate outer hair cells. The ipsilateral TEOAE-eliciting click stimulus level WN have strong impact recorded suppression.TEOAEs were nonlinear stimulation mode two...
Objective: The software application FOX (‘Fitting to Outcome eXpert’) is an intelligent agent assist in the programing of cochlear implant (CI) processors. current version utilizes a mixture deterministic and probabilistic logic which able improve over time through learning effect. This study aimed at assessing whether this capacity yields measurable improvements speech understanding.Methods: A retrospective was performed on 25 consecutive CI recipients with median use experience 10 years...
Objective: This study aims to assess the feasibility of autonomous cochlear implant (CI) fitting by adult CI recipients based on psychoacoustic self-testing and artificial intelligence (AI).Design: A was performed six implanted with a Nucleus device. Two weeks after processor activation in clinic, 'self-fitting' session organized supervised simulated home environment. The recipient pure tone audiometry spectral discrimination tests as self-tests. AI application FOX analysed results...
ObjectivesCochlear's new sound processor system (Nucleus® 6) features a noise reduction algorithm called SNR-NR (signal-to-noise ratio), and an environmental classifier SCAN, which activates the appropriate coding algorithms for given listening environment. In addition, processors (CP910 CP920) have data logging feature with visually summarized using clinical programing software come two remote controls, CR210 CR230. The objective of this study was to conduct field acceptance comparing user...
Roger is a digital adaptive multi-channel remote microphone technology that wirelessly transmits speaker's voice directly to hearing instrument or cochlear implant sound processor. Frequency hopping between channels, in combination with repeated broadcast, avoids interference issues have limited earlier generation FM systems. This study evaluated the benefit of Pen transmitter multiple talker network (MTN) for users simulated noisy conversation setting. Twelve post-lingually deafened adult...
Background: Congenital deafness leads to major problems in speech, language, education, and social integration. Neonatal hearing screening cochlear implantation now allow early restoration. This article reports on a prospective longitudinal study of the first infant ever who received two implants prelexical period her life. Methods: The deaf-born girl at ages 5 15 months, respectively, was followed-up with repeated detailed quantitative assessments from birth 4 years age. consisted 1)...
Objective. This report describes the application of software tool “Fitting to Outcomes eXpert” (FOX) in programming cochlear implant (CI) processor new users. FOX is an intelligent agent assist CI processors. The concept modify maps on basis specific outcome measures, achieved using heuristic logic and based a set deterministic “rules”. Design. A prospective study was conducted eight consecutive CI-users with follow-up three months. Study Sample. Eight adult subjects postlingual deafness...
Objective A model is proposed for universal neonatal hearing screening. Methods The screening two-staged because it consists of a first test and, in case failure (1.4% the subjects), retest 3 weeks later. It bipodal involves both hospital audiologic department and central Well Baby Organization. idea to have maximal number newborns tested at maternity by trained audiologists Organization trace chase missing subjects. has been evaluated during 1 calendar year (1999) with 2,012 newborns....

The present paper reports on the implementation of a neonatal hearing screening programme in private hospital Belgium. A maternity-based project with transient evoked otoacoustic emissions (TEOAEs) was started 1993. cost test not covered by public health insurance, so parents had to pay full for their child (approximately 30 Euro). Since 1993 strategies have been changed several occasions improve quality and efficacy. retrospective analysis performed on: (1) pass rate; (2) coverage; (3)...
The perception of pitch has recently gained attention. At present, clinical audiologic tests to assess this are hardly available. This article reports on the development a test using harmonic intonation (HI) and disharmonic (DI).Prospective collection normative data pilot study in hearing-impaired subjects.Tertiary referral center.Normative were collected from 90 normal-hearing subjects recruited 3 different language backgrounds. was conducted 18 individuals who selected into pathologic...
The A(section)E((R)) is a set of suprathreshold tests for the auditory evaluation hearing impaired. A particular population interest hearing-impaired preverbal child. This paper reports on normative data discrimination test in children aged 10 months and identification 2 to 4 years. Normally these ages were tested pass criteria defined such way that 95% infants would tests. With criteria, feasible at age section signE((R)) from 30 age.
Objectives: The newest Nucleus CI processor, the CP900, has two new options to improve speech-in-noise perception: (1) use of an adaptive directional microphone (SCAN mode) and (2) wireless connection MiniMic1 MiniMic2 remote microphones. Design: An analysis was made absolute relative benefits these technologies in a real-world mimicking test situation. Speech perception tested using (sentences-in-babble noise).
