Mammalian inner ear harbors diverse cell types that are essential for hearing and balance. Adenovirus is one of the major vectors to deliver genes into the inner ear for functional studies and hair cell regeneration. To identify adenovirus vectors that target specific cell subtypes in the inner ear, we studied three adenovirus vectors, carrying a reporter gene encoding green fluorescent protein...
OBJECTIVE To evaluate vestibular function before and after cochlear implantation (CI) STUDY DESIGN: A prospective descriptive study. MATERIAL AND METHODS Thirty consecutive patients with profound sensorineural hearing loss undergoing CI. Objective assessment of vestibular function was performed with the caloric test and video head impulse test (vHIT) in patients before and after CI. Dizziness...
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 surgery through the middle cranial fossa. ...
CONCLUSION With optical coherence tomography (OCT) it is basically possible to reveal parts of the cochlear morphology without opening its enveloping membranes. Thus, it may serve as a helpful guide for the surgeon to localize the scala tympani precisely before opening the fluid-filled inner ear to insert the electrode array. OBJECTIVE To improve anatomical orientation in cochlear implant sur...
OBJECTIVE To test the influence of multiple factors on cochlear implant (CI) speech performance in quiet and in noise for postlinguistically deaf adults, and to design a model of predicted auditory performance with a CI as a function of the significant factors. STUDY DESIGN Retrospective multi-centre study. METHODS Data from 2251 patients implanted since 2003 in 15 international centres wer...
Cochlear implantation has become an increasingly common procedure in the rehabilitation of selected cases of profound deafness.' Patients should have profound total bilateral sensorineural hearing loss. Sound is transformed into small electric currents which stimulate the auditory nerves in the cochlea and generate the hearing sensation. The nucleus cochlear implant is the result of more t...
performing cochlear implantation in patients with inner ear malformation has always been a matter of dispute. this study was designed to analyze the operative findings,complications, and postoperative performance of patients with inner ear anomalies who underwent cochlear implantation. six patients with inner ear malformations underwent implantation in our academic tertiary referral center from...
OBJECTIVE The aim of this study was to present the surgical findings of children with Waardenburg syndrome (WS) and investigate speech development after cochlear implantation in this unique group of patients. MATERIALS AND METHODS A retrospective chart review of the patients diagnosed with WS and implanted between 1998 and 2015 was performed. Categories of auditory performance (CAP) test were...
