Spatial Hearing Perception in Bilateral Cochlear Implant Children

Spatial hearing in cochlear implant (CI) users is a challenging investigation field since no studies have explored yet spatial auditory perception in three-dimensional space (3D). Moreover auditory rehabilitation after cochlear implantation is totally devoted to speech rehabilitation to date. A novel methodology based on virtual reality and 3D motion capture protocol in an immersive reality system has recently been developed to evaluate and record spatial hearing abilities ...

A New Predictor Marker for Cochlear Implants Infection

Introduction: Surgical site infections associated with the cochlear implant can have serious consequences. Although advances in surgical techniques reduce these complications, it may be necessary to remove a device that works as a last resort as a result of ongoing infection. The removal of these devices, which are very expensive, increases the cost and takes the chance of hearing patients with this device. Therefore, it is very important to identify patients with a tendency to...

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...

Establish a Concordance Between the Mismatch Negativity Amplitude and a Score of Logatoms Discrimination

A cochlear implant is a device for the rehabilitation of severe to profound hearing loss. Despite the standardization of surgical procedures and rehabilitation, speech discrimination performance varied significantly in cochlear implant users and could be improved by early individualized cares. However, there is no objective method yet to evaluate phonemes discrimination, especially in infants, which account for more than half of the indications for implantation. In electroencep...

Evaluation of a Bio-inspired Coding Strategy for Cochlear Implant Users

This study will determine the facilitation, refractoriness and spatial spread effects of auditory nerve fiber responses to electrical stimulation via a cochlear implant. The performance of CI users in melody contour and speech recognition in noise tests with their own clinical sound processor and a MATLAB implementation of their coding strategy will be compared and a bioinspired coding strategy will be evaluated in comparison with the conventional ACE coding strategy.

Cochlear Implant Speech and Non-speech Sound Recognition

The primary purpose of the research is to study how synthesized speech and non-speech percepts (sounds) are recognized in subjects with cochlear implants (CI) who are not getting functional speech recognition using existing speech to CI algorithms. By identifying a partial set of phonemes (units of speech) from this CI feedback, a new language could be developed.

The programming of the CI carried out during the first year after the surgical insertion is done on the foundation of the obje...

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.

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...

Cochlear Electrical Impedance and the Effect of Topical Dexamethasone on Cochlear Implant Surgery

Hearing is the ability to perceive sounds through the ear. If the transmission of sound is defective, the person suffers some degree of hearing loss. Cochlear Implants (CI) provide partial hearing by stimulating auditory nerve cells. The evaluation of the functionality of the CI is facilitated by several analysis tools, such as the clinical calibration software. This offers the possibility of measuring electrical impedances in the cochlea. The electrical impedance is the oppos...

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...
