OBJECTIVE To estimate a residual hearing preservation in cochlear implant patients in short-, and long-term observation. MATERIAL AND METHODS A group of 40 subjects with preserved residual hearing were included to this study. In all of them cochlear implant was provided due to a neurosensonal hearing loss. In all subjects hearing was tested using traditional audiological test battery. Cochlea...

INTRODUCTION We introduce a rating tool that objectively evaluates the skills of surgical trainees performing cochlear implant surgery. METHODS Seven residents and seven experts performed cochlear implant surgery sessions from mastoidectomy to cochleostomy on a standardized virtual reality temporal bone. A total of twenty-eight assessment videos were recorded and two consultant otolaryngologi...

Cochlear implantation is now being performed in ears with residual hearing. Those implant recipients who keep residual hearing may benefit from improved pitch resolution through both electrical and acoustic hearing. Preservation of cochlear function after implantation is a challenging task for the surgeon. Current topics of hearing preservation research include electrode design and surgical tec...

Objective. To share our experience of cerebrospinal fluid gusher in cochlear implantation in patients with enlarged cochlear or vestibular aqueduct. Study Design. Case series with comparison and a review of the literature. Methods. A retrospective study was performed. Demographic and radiological results of patients with enlarged cochlear aqueduct or enlarged vestibular aqueduct in 278 consecut...

The patho-physiology of inner ear is an intriguing entity, which is yet to be understood in its full entirety. It is an interesting phenomenon to explore the way in which the labyrinth responds to various insults with a myriad of presentations manifesting clinically. Otologists have long wondered for a reasonable explanation as to why Stapedotomy patients may develop intense post-operative vert...

AIMS The objective of this study was to describe our surgical techniques following the general principles of cochlear implantation focusing on the small and thin design of the SONATATI(100) implant device. METHODS From May 2007 to December 2010, 97 patients were implanted with the SONATATI(100) device. Due to the titanium housing, a bony bed and a muscle-periost pocket were created to host th...
