Cochlear implant technology is growing rapidly in Malaysia to assist patients with hearing problems especially among children. Cochlear implants may be beneficial for the speech development of children and help children attend normal schools. However, the success of cochlear implants depends on the detection and early intervention of children and efforts to habilitation / rehabilitation by therapists and parents.. The latest scenario in Malaysia, most users only use cochlear implant in one ear only. Therefore, various studies have been conducted to evaluate the benefits of cochlear implants. According to a study on the use of cochlear implant and its impact on the binaural processing for pediatric patients and adults showed that patients using bimodal fitting get better benefits than patients using cochlear implant or hearing aid in one ear only (Molly Justus, 2008).. ...
OBJECTIVE: To conduct a pilot study in adults with the Nucleus CI24M/SP5 cochlear implant system. PATIENTS AND METHODS: Eight postlingually deafened adults who had received little or no benefit from conventional hearing aids, equipped with the Nucleus CI24M/SP5 cochlear implant system. RESULTS AND CONCLUSIONS: The results indicate that most of the subjects were able to perform well in speech recognition tests. The test performances appeared to be strongly affected by the duration of deafness. The speech processors four user-selectable program memories have been extremely useful for the subjects to evaluate variations to the speech coding strategies in ordinary surroundings outside of the laboratory. The telemetry functions of the new implant provide a set of useful clinical and research tools for gathering greater insights into the in-situ operation of the implant. ...
TY - JOUR. T1 - Loudness balance between acoustic and electric stimulation by a patient with a multichannel cochlear implant. AU - Dorman, Michael. AU - Smith, L.. AU - Parkin, J. L.. PY - 1993/8. Y1 - 1993/8. N2 - Estimates of loudness balance were obtained for acoustically and electrically presented 250 Hz sine signals from a patient who uses the Ineraid multichannel cochlear implant. Acoustic and electric loudness matching was possible because the patient evidenced a 25 dB HL threshold at 250 Hz in his nonimplanted ear. The level of the electrical stimulus in microamperes required for a balance of loudness grew linearly with equal increments in decibels for the acoustic stimulus. These data, in concert with the very limited data from previous studies, provide a rationale for using a logarithmic transformation of acoustic to electric intensity in signal processors for cochlear implants.. AB - Estimates of loudness balance were obtained for acoustically and electrically presented 250 Hz sine ...
Children with profound deafness are at risk for serious reading difficulties. Multiple factors affect their development of reading skills, including use of cochlear implants. Further, multiple factors influence the overall success that children experience with their cochlear implants. These factors include the age at which they receive an implant, method of communication, vocabulary skills, preoperative residual hearing, and socioeconomic status. Ninety-one children with prelingual and profound hearing impairments who received cochlear implants at varying ages participated in the study. Structural equation modeling confirmed that multiple factors affected young cochlear implant users reading comprehension skills and that there were significant associations between the predictors of reading comprehension. Pre-implant vocabulary had an indirect positive effect on reading through postimplant vocabulary, which had a direct positive effect on reading. Overall, children with stronger language skills ...
OBJECTIVES: Monopolar stimulation of the most apical electrode produces the lowest pitch sensation in cochlear implants clinically. A phantom electrode that uses out-of-phase electrical stimulation between the most apical and the neighboring basal electrode can produce a lower pitch sensation than that associated with the most apical electrode. However, because of the absence of contacts beyond the apical tip of the array, the ability to assess the spread of electrical excitation associated with phantom stimulation is limited in the typical cochlear implant subject with no residual hearing. In the present study, the spread of electrical excitation associated with monopolar and phantom stimulation of the most apical electrode was assessed using electrical masking of acoustic thresholds in cochlear implant subjects with residual, low-frequency, acoustic hearing. DESIGN: Eight subjects with an Advanced Bionics cochlear implant and residual hearing in the implanted ear participated in this study ...

Cochlear implant and hearing loss videos including educational videos, cochlear implant testimonials and cochlear implant product videos
by Susan Boswell These are often the first words spoken when a cochlear implant recipients processor is turned on. And they have been a rite of passage for more than 36,000 people around the world who have received cochlear implants over the last two decades. Technological advances have brought dramatic changes in candidacy criteria, opening the door for more people with severe and profound hearing losses to choose this option.. When the U.S. Food and Drug Administration (FDA) first approved a cochlear implant with a single electrode for adults in 1985 and for children in 1990, only those who were almost completely deaf and could only perceive vibrations with a hearing aid could qualify.. Today, children and adults who were not candidates just two years ago may well be considered as candidates. The age of pediatric candidates has dropped from 2 years to as young as 12 months, and eligibility criteria for adults continue to expand.. A growing body of research has demonstrated that children who ...

AzBio sentences are spoken by different talkers in a conversational style with limited contextual cues that the listener can use to predict or fill in unintelligible words. Each list includes 5 sentences from 4 different male and female speakers. Each word in the sentence counts towards the overall score. ...
Cochlear implants were created for adults and children that suffer from a form of hearing loss known as sensorineural hearing loss. In sensorineural hearing loss there is usually damage to the tiny hair like cells in the cochlea. The cochlea is the tiny snail shaped coil in your inner ear that transmits sound signals to the auditory nerve. When the tiny hair like cells in your cochlea are damaged they are unable to transmit the sound signals to the auditory nerve. The cochlear implant circumvents the cochleas tiny hair like cells and directly stimulates the auditory nerve.. So how does the cochlear implant work? First a tiny receiver is implanted just under your skin behind the ear. This receiver is then connected to tiny electrodes that have been placed in the cochlea. You are then fitted with an external auditory speech processor, a transmitter and a battery pack. The microphone looks like a hearing aid and is worn behind the ear or it can be worn somewhere else on your body depending on your ...

A cochlear implant is an electronic device that transmits electrical impulses to the brain where they are perceived as sounds both for children who are born deaf or become deaf and also deaf or severely hard of hearing adults.. The cochlear implant consists of two parts:. - the external part with a speech processor incorporating a microphone which is placed behind the ear with a transmitter coil or with a compact, single-unit audio processor that is held in place by magnets over the implanted receiver. - a surgically implanted internal part consisting of a receiver package implanted in a recess in the mastoid bone which is connected to the electrode array positioned within the cochlea.. Today the possibility of obtaining a cochlear implant in Europe is still very uneven and depends in particular on the social insurance system of the country concerned.. It should be remembered that health policy in the European Union is in the first place the responsibility of each state member.. Numerous ...
Purpose: The purpose of this study was to examine the rate of progress in the 2nd implanted ear as it relates to the 1st implanted ear and to bilateral performance in adult sequential cochlear implant recipients. In addition, this study aimed to identify factors that contribute to patient outcomes. Method: The authors performed a prospective longitudinal study in 21 adults who received bilateral sequential cochlear implants. Testing occurred at 6 intervals: prebilateral through 12 months postbilateral implantation. Measures evaluated speech recognition in quiet and noise, localization, and perceived benefit. Results: Second ear performance was similar to 1st ear performance by 6 months postbilateral implantation. Bilateral performance was generally superior to either ear alone; however, participants with shorter 2nd ear length of deafness (|20 years) had more rapid early improvement and better overall outcomes than those with longer 2nd ear length of deafness (|30 years).

My attitudes and perspectives about young deaf children getting cochlear implants have gradually evolved since the first time I heard about deaf people getting cochlear implants. Growing up with deaf parents and attending deaf schools, I have a strong sense of pride of being deaf and being part of the Deaf community. I do not look at myself as disabled. I often say if I were given a choice to hear or stay deaf, I d choose to stay deaf. It is who I am. My family, my friends, and my community have taught me that being deaf is part of our culture and is a way of life. Many deaf people have succeeded in life without having the ability to hear. They ve become lawyers, doctors, scientists, and teachers. It has nothing to do with the ability to hear. It has to do with many other factors such as the person s attitude, values, beliefs, and motivation.. I used to oppose strongly the idea of deaf people getting cochlear implants. It indicates the need to fix the problem. I felt betrayed and angry that ...
The George Washington University Hospital offers cochlear implants for patients with hearing loss. A cochlear implant is a small, electronic device that can provide sound perception to a person who is deaf or severely hard-of-hearing. The device can be particularly useful for people who receive little or no benefit from hearing aids. Cochlear implants have two major
Objectives/Hypothesis: This study documents the importance of preserving residual low-frequency acoustic hearing as those with more residual hearing are selected for cochlear implantation. Surgical strategies used for hearing preservation with a short hybrid cochlear implant are outlined. The benefits of preserved residual low-frequency hearing, improved word understanding in noise, and music appreciation are described.. Study Design: Multicenter, prospective, single-subject design.. Methods: Records were reviewed of 21 individuals participating in an Food and Drug Administration (FDA) feasibility clinical trial who have received an Iowa/Nucleus 10 mm electrode. A second group of subjects receiving implants at the University of Iowa that have used the 10 mm device between 2 years and 6 months were also reviewed. Outcome measures included standardized tests of monosyllabic word understanding, spondees in noise, and common melody recognition.. Results: Low-frequency hearing was maintained in all ...
CRITIQUE: The number of children who receive cochlear implants is increasing, likely the result of many factors such as universal newborn hearing screening, improvements in audiological testing, and advances in hearing technology. Additionally, there has been a trend to provide cochlear implants to children at much younger ages than in the past. This book is an appropriate resource for students enrolled in college training programs and is also appropriate for school professionals who are new to the field of cochlear implants as well as those that have been working with implants for several years. The book addresses the issue that the procedures used to educate children with hearing losses have changed significantly over recent years. As the authors indicate, this book does not answer all questions regarding educational issues of such children, but does provide the reader with good references regarding this topic. One of the main strengths of the text is its emphasis on a team approach to ...

The present thesis investigated cognitive ability in children with severe to profound hearing impairment who have received cochlear implants (CIs). The auditory stimulation from a cochlear implant early in life influences most cognitive functions as a consequence of the plasticity of the brain in the young child. It is important to understand the cognitive consequences of auditory stimulation from CIs in order to provide adequate support to these children. This thesis examined three specific aspects of cognitive ability (working memory, phonological skill and lexical access), and reading ability in children with CIs, as compared to children with normal hearing in the same age. The relations between cognitive abilities and reading skills were also investigated, as well as the associations between demographic variables (e.g., age at implantation and communication mode), cognitive abilities and reading skills. The children with CI generally had lower performance levels than the normal hearing ...

The Hybrid cochlear implant (CI) has been developed for individuals with high frequency hearing loss who retain good low frequency hearing. Outcomes have been encouraging but individual variability is high; the health of the cochlea and the auditory nerve may be important factors driving outcome. Electrically evoked compound action potentials (ECAPs) reflect the response of the auditory nerve to electrical stimulation while electrocochleography (ECochG) reflects the response of the cochlear hair cells and auditory nerve to acoustic stimulation. In this study both ECAPs and ECochG responses were recorded from Nucleus Hybrid L24 CI users. Correlations between these two measures of peripheral auditory function and speech perception are reported. This retrospective study includes data from 25 L24 CI users. ECAPs and ECochG responses were recorded from an intracochlear electrode using stimuli presented at or near maximum acceptable loudness levels. Speech perception was assessed using Consonant-Nucleus
This update explores the importance of early auditory stimulation by considering the development of speech processing skills in profoundly deaf children who have received a cochlear implant. This literature is relevant to issues affecting children with Down syndrome, because like them, children with cochlear implants have hearing difficulties, but unlike the former, they do not have oral-motor issues.

A cochlear implant (CI) is an electronic device that can provide a sense of hearing to deaf or profoundly hearing impaired listeners by directly activating auditory nerve fibers. Optimal auditory performance with a CI requires subject-specific adjustments of several system parameters, i.e. the CI needs to be "fitted" to the individual user. A large number of system parameters is available to the clinician in the fitting software. For some of these parameters it is essential that they are individualized prior to switching on the device, since they ensure that sounds are audible without making sounds uncomfortably loud. For other parameters subject-specific optimization is less essential and a one-size-fits-all approach of using default settings results in good performance for the majority of CI users. However, these default settings may not always result in optimal settings for individual CI users and subject-specific fine-tuning of these parameter settings may further improve performance and/or ...

One of the things that attracted me to the Dept. of Speech and Hearing Science was the opportunity to do translational research. We have faculty members who come from a wide variety of backgrounds-neuroscience, engineering, linguistics, speech and language science, hearing science-focused on work that will address the challenges of people with communication disorders.. A cochlear implant is an auditory prosthesis for people who are severely to profoundly hearing-impaired. Originally, these implants were designed for people who were so deaf, they could only feel the sound that is amplified by a hearing aid. Cochlear implants change sound to electrical signals that are sent across the skin to an electrode array thats placed in the inner ear [the cochlea]. The electrodes are stimulated, which causes information to be sent to the auditory nerve and then on to the brain, where people process it.. Cochlear implants are not like eyeglasses, where you put them on and your vision is 20/20. The signal is ...
This project aims to improve access to care and increase patient empowerment by scaling up a successful service where people with cochlear implants are offered a personalised online support tool, home hearing test and support to adjust devices themselves.
During normal hearing, sound waves travel through the ear canal and strike the eardrum causing it to vibrate. The eardrum is attached to three tiny bones in the middle ear. The last bone, the stapes, pushes on a fluid-filled chamber in the inner ear, called the cochlea. This fluid movement causes sensitive hair cells within the cochlea to bend. When the hair cells bend, they generate an electrical signal that is sent to the brain. Disease, damage, or deformity of the cochlear hair cells is a common cause of hearing impairment or deafness. These malfunctioning hair cells may send intermittent or unclear signals to the auditory nerve, or send no signal at all. A device called a cochlear implant can restore hearing by replacing these damaged structures with a wire that is implanted in the cochlea. In order to stimulate the hearing process, sound waves are first received by a microphone unit, or speech processor, that hangs over the back of the ear. Within the processor, sound is filtered and ...
