UNLABELLED The auditory brainstem implant (ABI) was first developed to help neurofibromatosis type 2 patients. Recently, its use has been recently extended to adults with non-tumor etiologies and children with profound hearing loss who were not candidates for a cochlear implant (CI). Although the results has been extensively reported, the stimulation(More)
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(More)
Introduction 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(More)
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(More)
CONCLUSION The study shows that there are differences in the measurement of the action potentials with and without the stylet in the Nucleus Freedom Contour Advance that are higher in the apex than in the base of the cochlea. OBJECTIVES To determine if there are differences in the intraoperative impedances and in the neural response telemetry threshold(More)
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(More)
Introduction The factors that affect the development of children with and without hearing disabilities are similar, provided their innate communication abilities are taken into account. Parents need to mourn the loss of the expected normally hearing child, and it is important that parents create bonds of affection with their child. Objective To conduct a(More)
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(More)
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(More)
