Event-related Potentials(ERP) in Cochlear Implant Recipients. 1. Results of the Performance.

The Cochlear Implant

The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi­ complete loss of har cel...

Radiation therapy in cochlear implant recipients.

HYPOTHESIS Processes of scattering and attenuation were investigated to determine the consequence on dose distributions by having a cochlear implant in the field of therapeutic radiation. BACKGROUND Radiation oncology medical accelerator beams of 6- and 18-MV x-ray energy were used. Five cochlear implants were investigated. METHODS Each implant model was individually studied using computer ...

Cochlear implant recipients at risk for meningitis.

Discrimination of speech sound contrasts determined with behavioral tests and event-related potentials in cochlear implant recipients.

Cortical potentials evoked with speech stimuli were investigated in ten experienced cochlear implant (CI, type Nucleus 24M) users using three different speech-coding strategies and two different speech contrasts, one vowel (/i/-/a/) and one consonant (/ba/-/da/) contrast. On average, results showed that, compared to subjects with normal hearing, P300 amplitudes were smaller; however, most laten...

The management of myringotomy tubes in pediatric cochlear implant recipients.

OBJECTIVE To investigate the impact of myringotomy tubes (MTs) on outcomes for pediatric cochlear implant (CI) recipients. DESIGN Retrospective case-control chart review. SETTING Tertiary care pediatric hospital. PATIENTS Sixty-two patients received an MT before CI (mean [SD] age at initial CI, 3.20 [2.45] years). Seventy-eight ears received CIs and MTs. INTERVENTION The MTs were remove...
