Receptive language as a predictor of cochlear implant outcome for prelingually deaf adults.

Abstract: Objective: This study investigated outcomes and predictive factors, specifically language skills, for a group of prelingually hearing-impaired adults who received a cochlear implant Design: Speech perception data, demographic information, and other related variables such as communication mode, residual hearing, and receptive language abilities were explored Pre- and post-implant speech perception scores were compared and multiple regression analysis was used to identify significant predictive relationships Study sample: The study included 43 adults with a prelingual onset of hearing loss, who proceeded with cochlear implantation at the Royal Victorian Eye and Ear Hospital in Melbourne, Australia Results: The majority of patients experienced benefit from their cochlear implants, with 88% demonstrating significant improvement in speech perception performance Volunteers achieved better post-operative speech perception scores if they had a shorter duration of severe-to-profound hearing loss, bett

Cochlear implant in patients with single sided deafness: hearing results and communicative benefits.

Abstract: Objective: Evaluate auditory results and communicative benefits in adult patients with single-sided deafness (SSD) treated with cochlear implantation.Study Design: Observational descriptive case series.Setting: Hospital Universitario Fundacion Santa Fe de Bogota.Patients: Ten patients with profound post-lingual SSD were treated with cochlear implantation between January 2011 and March 2016. Two patients were excluded because of incomplete follow-up.Interventions: Medical records included demographic information, pre and post-operative audiometric results, and binaural and monoaural speech discrimination tests in three sound-in-noise configurationswith the cochlear implant turned on and off, respectively. Subjective improvement was evaluated using the Abbreviated Profile of Hearing Aid Benefit (APHAB) and Speech, Spatial, and Qualities of Hearing Scale (SSQ-B).Main Outcome Measures: Pre and post-operative audiometric and speech discrimination results, post-operative binaural and monoaural speech discrimination in noise results, and APHAB and SSQ-B questionnaire results.Results: Significant improvement in speech discrimination in a noisy environment was found when the noise and signal were presented from the front, and when the signal was presented to the implanted ear and the noise to the healthy ear. SSQ-B questionnaire showed improvement in all subscales, while APHAB showed improvement in all subscales except sound aversion.Conclusion: Patients with SSD showed improvement regarding communication skills and sound discrimination in a noisy environment.

Evaluation of electrically elicited stapedius reflex threshold measured through three different cochlear implant systems.

Abstract: Objective: To evaluate intraoperative electrically elicited stapedius reflex thresholds (ESRTs) measured through three different cochlear implant systems: the Nucleus Mini 22, the Clarion Enhanced Bipolar, and the Med-El Combi-40. Subjects and Methods: Relations between intraoperative ESRT and postoperative maximum comfort level (MCL) were examined in seven children (4 Nucleus, 2 Clarion, and I Med-El) and one adult (Clarion). Results: Preliminary results indicated most ESRTs were either higher or both higher and lower (across the electrode array within a subject) than MCLs. All systems provided satisfactory means for measuring ERSTs. Conclusion: It is recommended that hand-held systems have a direct readout to the programming station and that audio and visual feedback be improved for all units

Sound processing based on a confidence measure

Abstract: A method for processing sound that includes, generating one or more noise component estimates relating to an electrical representation of the sound and generating an associated confidence measure for the one or more noise component estimates. The method further comprises processing, based on the confidence measure, the sound.
