Preoperative Variables Affecting Outcome Of Cochlear Implant

Cochlear implants (CIs) represent one of the most important achievements of modern medicine as, for the first time in history, an electronic device is able to restore a lost sense - hearing. As of December 2012, approximately 324,200 cochlear implants have been implanted worldwide. In the United States, roughly 58,000 devices have been implanted in adults and 38,000 in children . The aim of this study is to assess the factors affecting the audiological, speech and langua...

Language Environment in Children With Cochlear Implants

The Language Environment Analysis (LENA) system is a specific tool for the language environment analysis. Children aged from 18 months to 6 years old, with cochlear implants (CIs), wear an electronic device during a day and their language interactions are registered. Then the investigators can analyze with a specific software four different parameters (adult words, conversational turns, child vocalizations and media exposure) and compare them to the language ability of the chil...

Balance in Children With Cochlear Implants

Auditory Neuropathy and Cochlear Implants

The electrical stimulation generated by the Cochlear Implant (CI) may improve the neural synchrony and hence contribute to the development of auditory skills in patients with Auditory Neuropathy / Auditory Dys-synchrony (AN/AD). Goal: The goal of the research was to evaluate the auditory performance and the characteristics of the electrically evoked compound action potential (ECAP) in a group of 18 cochlear implants recipients with AN/AD.The auditory perception was evaluated by...

Exploring the Use of ECochG Testing During Electrode Insertion in Cochlear Implant Surgery

Investigation of a new ECoChG system (Electrocochleography) during the surgical insertion of cochlear implants, for patients with Advanced Bionics devices. The sound recordings created may be useful in aiding the surgeon to better implant the patient by letting him or her know if they are damaging the ear during implantation in real time Patients will be followed up for 1 year post surgery within our trial, and have a further 3 ECochGs performed in the clinic setting, (...

Pediatric Image-Guided Cochlear Implant Programming

Cochlear implants are surgically implanted devices which restore the ability to hear to the hearing impaired. Recent literature has indicated that children receiving cochlear implants (CIs) often have dramatically improved speech and language ability relative to previous generations of children with hearing loss; however, many pediatric CI recipients display persistent speech and language disorders despite early implantation and associated speech/language intervention. Cochlear...

Pilot Study of the Feasibility and Efficacy of Working Memory Training in Children With Cochlear Implants

This study is an investigation of the effect of a computer-based working memory training program on memory and language processing in at-risk children (e.g., those with working memory weaknesses) who have received cochlear implants.

Follow-up of Cochlear Implanted Children at 3 Years : Comparison of Electrophysiological and Speech-language Results

The objective of the study is to compare the responses recorded with automated cortical auditory evoked potentials, of children who had one or two cochlear implants for 3 years, and the results of the speech therapy assessment.

Expanded Indications in the MED-EL Pediatric Cochlear Implant Population

The purpose of this investigation is to demonstrate the safety and effectiveness of MED‐EL cochlear implants in children 7 months to 5 years, 11 months of age who fall outside the current FDA‐approved candidacy criteria and, yet, continue to demonstrate insufficient functional access to sound with appropriately fit hearing aids and aural habilitation.

Development of a Deaf Child With a Cochlear Implant.

Cochlear implantation enables profoundly deaf children to acquire speech and develop their understanding of spoken language. However, there are significant interindividual differences in the results obtained with the implant. Given the lack of theoretical knowledge on acoustic predictors, cognitive and language to obtain optimum speech recognition with cochlear implants associated with a good communicative and language development of deaf children, the investigators intend to a...

Bilateral Cochlear Implant Benefit in Young Children

The primary purpose of this study is to track patient outcomes for bilateral cochlear implant recipients in a cohort of 60 children, ages 12 to 36 months at time of surgery, who receive two implants in the same operation or in two different surgeries with the initial fitting of the devices separated by no more than six months.

Balance in Children With Cochlear Implants

Cochlear implantation is performed in children with sensorineural hearing loss to restore hearing. Fifty percent of children with sensory neural hearing loss, who are candidates for cochlear implant, have vestibular (inner ear) dysfunction prior to surgery. Anatomically, the cochlea, semicircular canals, and otolith organs are located in close proximity in the inner ear and any procedure in the cochlea may affect the vestibular system, resulting in subsequent balance impairment...

Bilateral Cochlear Implantation in Children With the MED-EL Cochlear Implant

The purpose of this study is to evaluate and document longitudinal efficacy in young children implanted bilaterally with MED-EL COMBI 40+ / PULSARCI100/SONATATI100 cochlear implant systems.

Image-guided Cochlear Implant Programming (IGCIP)

Cochlear implants are surgically implanted devices which restore the ability to hear to the hearing impaired. While remarkably successful, even in the best of performers restoration of hearing to levels of normal listeners is unusual. Approximately 3 weeks after surgery, cochlear implants are activated via mapping - a process in which each individual electrode (FDA approved cochlear implants have between 12 and 22 electrodes) is turned on and the stimulus level adjusted to a le...

Optimization of Cochlear Implant MAP-parameters in Children

This project will complete a long-term follow up for children that have received cochlear implants (CI) early in life and had their CI's programmed based on objective measurements. At Sahlgrenska University Hospital in Gothenburg, generally, all younger children (0-3 years), the last ten years, had their CI's programmed based on objective measurements. The programming of the CI carried out during the first year after the surgical insertion is done on the foundation of the obje...

Cochlear Implants : Influence of Microphone Aging and Dirtying

Cochlear implant microphones are subject to aging and dirtying. The evolution may affect their efficiency. Several signal coding strategies are used in cochlear implants and their behaviour may be more or less affected by the aging process. In this work the investigators wish to assess this phenomenon.

Relationship Between Auto NRT and Behavioural T & C Levels With the Nucleus Freedom Cochlear Implant

Cochlear implants require programming on an individual basis to provide appropriate levels of electrical stimulation. This program, or "map", is placed in the speech processor of the cochlear implant. Success of implantation largely depends on the adequacy of this map. Cochlear implant fitting remains a difficult challenge in congenitally or pre-linguistically deafened children. It requires competence of experienced audiologists with expertise in behavioral techniques for heari...

Minimizing Facial Nerve Stimulation in Cochlear Implants

This study aims to understand how to manipulate the electrical stimulation from the cochlear implant to maximize hearing stimulation and minimize facial stimulation. It is know from animal data that the hearing and facial nerves have different sensitivities to things like electrical pulse shape, its pattern, and its duration. It is very unclear however if this applies to human cochlear implant patients, and what the optimal parameters are to selectively stimulate the hearing ne...

Middle East MED-EL Observatory Study

In the field of cochlear implant research, there are only few data on long-term observational studies available to gain knowledge on clinical effectiveness. Longitudinal comparisons of data collected in different clinics is challenging due to the heterogeneity in measures and procedure. This Registry represents a non-interventional systematic collection of clinical data in which prospective data from children and adults are collected as anonymized data sets, derived from ...


Iowa Cochlear Implant Clinical Research Center Study of SSD Using Med-El Cochlear Implants

The purpose of this study is to understand the speech perception in noise and in quiet and localization benefits in a laboratory setting in listeners that receive a cochlear implant in an ear with severe to profound hearing loss and have normal, or near-normal hearing in the opposite ear. We will also evaluate the functional benefit of restoring hearing to the impaired ear via questionnaires that subjects will be answering while listening in their natural environment.

Children's Bilateral Cochlear Implantation in Finland

The purpose of this study is to evaluate short and long term outcomes (benefits and side-effects) of bilateral cochlear implantation in Finnish children.

Littlears Auditory Questionnaire: Validation Study in CI Children

The LittlEARS Auditory Questionnaire is designed to assess the development of the auditory behavior in children during the first two (hearing) years. The questionnaire has been validated on children with normal hearing whose native language is German. A comparison was made between North American English speaking children with normal hearing and found that it was consistent with the German data. This study is to validate the questionnaire in children with cochlear implants.

Outcomes of Cochlear Implantation in Pediatrics

The cochlear implant (CI) is the most important progress in the treatment for adults and children with severe to profound bilateral sensorineural hearing loss who do not receive adequa¬te benefit from hearing aids and making possible better results in auditory, linguistic, social and academic development.

Clinical Investigation of New CI Delivery Models in an Adult Nucleus CI Population

Use of Artificial Intelligent (AI) technology to assist audiologists in programming cochlear implants.

Cerebral Activation and Bilateral Stimulation by Cochlear Implantation in Bilateral Deaf Adults

The primary objective to this study is to describe bilateral auditory information processing in profoundly deaf patients with bilateral cochlear implants compared with normal hearing patients. Assumption used is that due to the central consequences of bilateral deafness on binaural auditory information central processing, time between activation of the two cochlear implants is a decisive factor in bilateral implantation compared to unilateral implantation
