Speech Perception Changes in the Acoustically Aided, Nonimplanted Ear after Cochlear Implantation: A Multicenter Study.

In recent years there has been an increasing percentage of cochlear implant (CI) users who have usable residual hearing in the contralateral, nonimplanted ear, typically aided by acoustic amplification. This raises the issue of the extent to which the signal presented through the cochlear implant may influence how listeners process information in the acoustically stimulated ear. This multicenter retrospective study examined pre- to postoperative changes in speech perception in the nonimplanted ear, the implanted ear, and both together.

Benefit of Cochlear Implantation in Children with Multiple-handicaps: Parent's Perspective.

 The cochlear implants centers in the world are studying the cochlear implantation in children with multiple handicaps.  To develop a questionnaire to analyze the subjective benefits of the cochlear implantation in multiple handicapped children according to their parent's perspective.  A questionnaire was applied to 14 families of multiple handicapped children, aging from 2-12 years old and having from 11 months to 11 years of implant use.

Satisfaction and quality of life in users of auditory brainstem implant.

Purpose To evaluate satisfaction and quality of life of users of Auditory Implant Brainstem. Methods This is a cross-sectional and descriptive study conducted at Divisão de Clínica Otorrinolaringológica of Hospital das Clínicas of Faculdade de Medicina da Universidade de São Paulo, Brazil. For the research, 19 users of an Auditory Brainstem Implant answered the following questionnaires: KINDLR (Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents), for children and adolescents, their parents and/or caregivers; WHOQOL-BREF questionnaire, for adult participants; and the Satisfaction with Amplification in Daily Life (SADL) questionnaire culturally adapted to Brazilian Portuguese.

Residual Hearing Preservation with the Evo® Cochlear Implant Electrode Array: Preliminary Results.

 The preservation of residual hearing is currently an important challenge for cochlear implant surgeries. Indeed, if patients exhibit functional hearing after cochlear implantation, they can benefit from the combination of acoustical stimulation, usually in the low-frequencies and electrical stimulation in the high-frequencies. This combined mode of stimulation has proven to be beneficial both in terms of speech perception and of sound quality.

Minimally Invasive Surgery for Intracochlear Schwannoma Removal and Simultaneous Cochlear Implantation.

Introduction: Hearing preservation has not yet been reported in patients undergoing resection of intracochlear schwannomas. This study describes a minimally invasive procedure for intracochlear schwannoma resection with simultaneous cochlear implantation that resulted in good hearing.

Objective: This study aims to describe a minimally invasive procedure for intracochlear schwannoma resection with simultaneous cochlear implantation.

Converted and upgraded maps programmed in the newer speech processor for the first generation of multichannel cochlear implant.

Objective: To identify the technological contributions of the newer version of speech processor to the first generation of multichannel cochlear implant and the satisfaction of users of the new technology. Among the new features available, we focused on the effect of the frequency allocation table, the T-SPL and C-SPL, and the preprocessing gain adjustments (adaptive dynamic range optimization).

Study Design: Prospective exploratory study.

Audiological outcomes of cochlear implantation in Waardenburg Syndrome.

Introduction:  The most relevant clinical symptom in Waardenburg syndrome is profound bilateral sensorioneural hearing loss.

Aim:  To characterize and describe hearing outcomes after cochlear implantation in patients with Waardenburg syndrome to improve preoperative expectations.

Method:  This was an observational and retrospective study of a series of cases.

Research ethics in animal models.

Unlabelled: The use of animals in scientific experiments has been described since the fifth century BC. A number of scientific advances in health are attributed to animal models. The issue of the moral status of animals has always been debated.

Result on speech perception after conversion from Spectra® to Freedom®.

Unlabelled: New technology in the Freedom® speech processor for cochlear implants was developed to improve how incoming acoustic sound is processed; this applies not only for new users, but also for previous generations of cochlear implants.

Aim: To identify the contribution of this technology-- the Nucleus 22®--on speech perception tests in silence and in noise, and on audiometric thresholds.

Methods: A cross-sectional cohort study was undertaken.
