INTRODUCTION We introduce a rating tool that objectively evaluates the skills of surgical trainees performing cochlear implant surgery. METHODS Seven residents and seven experts performed cochlear implant surgery sessions from mastoidectomy to cochleostomy on a standardized virtual reality temporal bone. A total of twenty-eight assessment videos were recorded and two consultant otolaryngologi...

The continuous interleaved sampling (CIS) speech-processing strategy has been widely used for cochlear implants to extract speech envelope information without preserving phase information. In this study, a novel simulated phase-locking stimulation (SPLS) strategy, which detects zero-crossing times of the narrow-band signal of each band, was developed to extract both phase and amplitude-envelope...

Cochlear implants have become the treatment of choice for profoundly deaf adults and children who obtain little or no benefit from conventional amplification. Sounds are translated into small electric currents that stimulate the auditory nerves in the cochlea and generate hearing sensations. The Nucleus cochlear implant is the result of more than 20 yr of research and development, first at the ...

OBJECTIVE To examine the time course of maturation of P1 latencies in infant sequential and simultaneous bilateral cochlear implant recipients. DESIGN Retrospective case series. SETTING Pediatric collaborative cochlear implant program. PATIENTS Four children who received bilateral cochlear implants prior to age 2 years. INTERVENTION Cortical auditory evoked potential was completed to de...

HYPOTHESIS The aim of this study was to investigate the impact of cochlear implant electrode insertion on middle-ear low frequency function in humans. BACKGROUND Preservation of residual low frequency hearing with addition of electrical speech processing can improve the speech perception abilities and hearing in noise of cochlear implant users. Preservation of low frequency hearing requires a...

Purpose: This study examined the benefit of bimodal hearing (i.e., one cochlear implant and a contralateral hearing aid) for listening to words and sentences in quiet and in noise, the identification of vowels and immediate phonological memory. Method: Two groups of twenty adult cochlear implant recipients, those who used bimodal hearing on a regular basis, and those who used one cochlear impla...

OBJECTIVE The purpose of the present study was to investigate tone production performance of native Mandarin Chinese speaking children with cochlear implants and to evaluate the effects of age at implantation and duration of implant use on tone production in those children. METHODS Fourteen prelingually deaf children who had received cochlear implantation and 14 age-matched normal-hearing chi...
