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)
CONCLUSION The extended retrolabyrinthine approach (RLA) is a safe and reliable approach for auditory brainstem placement in children. The surgical landmarks to reach cochlear nucleus are adequately exposed by this approach. OBJECTIVE To describe a new approach option for auditory brainstem implants (ABIs) in children, highlighting the anatomical(More)
UNLABELLED Cisplatin is used frequently as an antineoplastic drug in the treatment of many different cancers. However, when used in doses over 360mg/m(2), ototoxicity may ensue, resulting in loss of hearing. Criteria for identifying and quantifying hearing loss have been devised. AIM To describe the features of different hearing loss classification(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)
OBJECTIVES To report the results of cochlear implantation via the middle fossa approach in 4 patients, discuss the complications, and present a detailed description of the programming specifications in these cases. STUDY DESIGN Retrospective case review. SETTING Tertiary-care referral center with a well-established cochlear implant program. PATIENTS(More)
BACKGROUND The aim of this study was to characterize the audiological profile accompanying oncological treatment in patients who had cancer in childhood and had been free of oncological treatment for at least 8 years. Our main interest lay in identifying the affected frequencies that interfered with speech intelligibility (SI) in those who had acquired(More)
UNLABELLED Neurofibromatosis 2 (NF2) is an autosomal dominant disease in which hearing loss is predominant. Auditory restoration is possible using cochlear implants (CI) or auditory brainstem implant (ABI). OBJECTIVE To assess the auditory results of CI and ABI in NF2 patients and review the literature. METHODS Four NF2 patients were prospectively(More)
OBJECTIVE To investigate occurrences of hearing loss and hearing complaints among patients with head and neck tumors who underwent radiotherapy. DESIGN Prospective case-control study. SETTING Tertiary care hospital. PARTICIPANTS Two hundred eighty-two participants underwent evaluation, including 141 with head and neck tumors and 141 as an age-matched(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)
UNLABELLED Auditory Brainstem Implants were developed to partially restore the hearing capabilities of patients without cochlear nerves bilaterally. AIM this paper aims to discuss the clinical and surgical findings of four ABI patients. MATERIALS AND METHOD Four patients diagnosed with bilateral schwannomas received auditory brainstem implants (ABI) and(More)
