INTRODUCTION The pterygopalatine fossa (PPF) is a narrow space located between the posterior wall of the antrum and the pterygoid plates. Surgical access to the PPF is difficult because of its protected position and its complex neurovascular anatomy. Endonasal approaches using rod lens endoscopes, however, provide better visualization of this area and are(More)
UNLABELLED Cochlear implantation is a safe and reliable method for auditory restoration in patients with severe to profound hearing loss. OBJECTIVE To describe the surgical complications of cochlear implantation. MATERIALS AND METHODS Information from 591 consecutive multichannel cochlear implant surgeries were retrospectively analyzed. All patients(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)
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)
UNLABELLED The classic approach for cochlear implant surgery includes mastoidectomy and posterior tympanotomy. The middle cranial fossa approach is a proven alternative, but it has been used only sporadically and inconsistently in cochlear implantation. OBJECTIVE To describe a new approach to expose the basal turn of the cochlea in cochlear implant(More)
OBJECTIVES/HYPOTHESIS The aim of this work was to define the anatomical landmarks, limitations, and difficulties of obtaining internal carotid artery (ICA) exposure via endonasal endoscopic approaches (EEA). STUDY DESIGN Cadaveric descriptive study. METHODS The ICA was dissected via EEA in 10 cadaveric specimens (20 sides) prepared with intravascular(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)
Introduction The complaints associated with the use of conventional amplifying hearing aids prompted research at several centers worldwide that ultimately led to the development of implantable devices for aural rehabilitation. Objectives To review the history, indications, and surgical aspects of the implantable middle ear hearing devices. Data Synthesis(More)
INTRODUCTION  The bone-anchored hearing aid (BAHA) is a bone conduction hearing device that transmits sound directly into the inner ear. It is mainly used in patients with conductive hearing loss associated with aural atresia, but it is also used in those with mixed and sensorineural hearing loss. GOALS  To review the main indications for BAHA, to analyze(More)
CONCLUSION Topical dexamethasone associated with hyaluronic acid in cochlear implant surgery demonstrated a statistically significant difference in the preservation of low-frequency thresholds when compared with topical dexamethasone alone and a control group. Topical dexamethasone alone was not superior in hearing preservation when compared to the control(More)
