Comparison of the Pediatric Cochlear Implantation Using Round Window and Cochleostomy
Introduction: Cochlear implantation (CI) is now regarded as a standard treatment for children with severe to profound sensor neural hearing loss. This study aimed to compare the efficacy of the round window approach (RWA) and standard cochleostomy approach (SCA) in the preservation of residual hearing after CI in pediatric patients. Materials and Methods: This double-blind ran...
متن کاملRound window electrocochleography before and after cochlear implant electrode insertion.
OBJECTIVE/HYPOTHESIS Previous reports have documented the feasibility of utilizing electrocochleographic (ECoG) responses to acoustic signals to assess trauma caused during cochlear implantation. The hypothesis is that intraoperative round window ECoG before and after electrode insertion will help predict postoperative hearing preservation outcomes in cochlear implant recipients. STUDY DESIGN...
متن کاملIntratympanic and Round-Window Drug Therapy: Effect on Cochlear Tinnitus.
Tinnitus is a common symptom for which few existing therapeutic approaches can produce reliable reduction or elimination. Chemical perfusion involves the delivery of medication directly into the inner ear via the round-window membrane. This report discusses the use of dexamethasone or gentamicin in 20 individuals who had inner ear diseases in which disturbing cochlear tinnitus was one of the sy...
متن کاملMultiple Window Least Squares Evolutionary Spectral Analysis
We present a multi–window method for obtaining the time-frequency spectrum of a non–stationary signal. This method is based on optimal combination of evolutionary spectra that are calculated by using multi– window Gabor expansion. The optimal weights are obtained by using a least square estimation method. An error criterion that is the difference between a reference time–frequency distribution ...
متن کاملA comparison between neural response telemetry via cochleostomy or the round window approach in cochlear implantation.
UNLABELLED There are two techniques for cochlear implant (CI) electrode placement: cochleostomy and the round window (RW) approach. OBJECTIVE This study aims to compare neural response telemetry (NRT) results immediately after surgery to check for possible differences on auditory nerve stimulation between these two techniques. MATERIALS AND METHODS This is a prospective cross-sectional stud...
