Evaluation of focused multipolar stimulation for cochlear implants: a preclinical safety study.

OBJECTIVE Cochlear implants (CIs) have a limited number of independent stimulation channels due to the highly conductive nature of the fluid-filled cochlea. Attempts to develop highly focused stimulation to improve speech perception in CI users includes the use of simultaneous stimulation via multiple current sources. Focused multipolar (FMP) stimulation is an example of this approach and has b...

Preclinical Stress Test for Coding Strategies in Cochlear Implants

Although modern cochlear implants (CI) are able to restore speech perception to a high degree, there is still a large potential for improvements e.g. in music perception and speech discrimination in noise. To evaluate and optimize novel coding strategies a toolbox was developed which calculates the excitation of the auditory nerve to sound stimuli. The toolbox includes detailed models of the CI...

Evaluation of Stability in Short Implants Compared to Standard Implants using Periotest ®: A Pilot Study

Introduction: Among different non-invasive approaches for determining the stability of the implant within the bone is to use a dynamic device called Periotest®.It is designed to provide objective measurement of tooth mobility. The aim of the present study is to evaluate the stress transfer and stability in short and standard dental implants using Periotest®</sup...

Implications for Cochlear Implants

Amplitude envelope co-varies with F0 in Mandarin lexical tones. It can cue lexical tone perception in a tone language such as Mandarin which uses different pitch contours for phonemic contrasts. The current study investigated whether amplitude envelope could also aid the perception of lexical tones in a language such as Cantonese which uses both pitch contour and relative pitch height for phone...

Speech Perception in Children with Cochlear Implants

Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
