Round 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 کاملComparison 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 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 کاملSurgical Anatomy of the Human Round Window Region: Implication for Cochlear Endoscopy Through the External Auditory Canal.
OBJECTIVE To enable development of an endoscope for cellular-level optical imaging of the inner ear. STUDY DESIGN A prospective study of 50 cadaveric human temporal bones to define detailed surgical anatomy of the round window (RW) region and the range of angles necessary to reach the RW membrane perpendicularly via the external ear canal. MAIN OUTCOME MEASURE The transcanal angle to the RW...
