objectives: the aim of present study was evaluation of saccule function in cochlear implant candidates with severe to profound sensory neural hearing loss before and after cochlear implantation methods: in this study 35 cochlear implant (ci) candidates with bilateral severe to profound sensory neural hearing loss before and about 30 days after cochlear implant and 20 normal-hearing cases as a c...

OBJECTIVES/HYPOTHESIS To propose an evidence-based strategy for the management of patients with advanced otosclerosis accompanied by severe to profound hearing loss. STUDY DESIGN Systematic review of the literature and development of treatment guidelines. METHODS A systematic review was conducted on (advanced) otosclerosis and cochlear implantation or stapedotomy. We focused on hearing resu...

OBJECTIVE We report a patient who underwent cochlear implantation in an ear with long-term deafness, after an acoustic neuroma had been removed surgically from the other, hitherto good ear and the cochlear nerve had subsequently been resected to relieve severe tinnitus. METHOD Case report. RESULTS The patient could not tolerate the cochlear implant, because of a moderate headache due to the...

OBJECTIVES/HYPOTHESIS The purpose of this study was to examine the timing of diagnostic and therapeutic services in cochlear implant recipients from a rural Appalachian region with healthcare disparity. STUDY DESIGN Retrospective analysis. METHODS Cochlear implant recipients from a tertiary referral center born with severe congenital sensorineural hearing loss were examined. Rural status an...

OBJECTIVES We report novel mutations in the POU3F4 gene resulting in congenital X-linked deafness DFN3, and describe the results of cochlear implantation in 4 boys (3 siblings) followed for an average of 3.5 years. METHODS The diagnosis of DFN3 was made in infant boys on the basis of the radiologic criteria of an underdeveloped modiolus, a wide cochlear fossette, and the presence of all cochl...

OBJECTIVE This study was designed to test the hypothesis that partial hearing conservation is attainable after cochlear implantation with a long perimodiolar electrode. Surgical strategies for hearing conservation during cochlear implantation are described. STUDY DESIGN Prospective, single-subject, repeated-measures design. SETTING Academic tertiary care center. PATIENTS Twenty-eight seve...

INTRODUCTION Otosclerosis is an osteodystrophy of the labyrinthine capsule producing conductive hearing loss. If the process invades the cochlea, a sensorineural hearing loss usually takes place. The cochlear implant is a good alternative in these patients. OBJECTIVE To ascertain the behaviour of cochlear implantation in otosclerosis. MATERIAL AND METHODS We reviewed a database of 250 patie...

OBJECTIVES/HYPOTHESIS In pediatric patients with congenital malformations of the inner ear, anomalies within the anatomy may facilitate unintentional insertion of the cochlear implant electrode into the internal auditory canal. Revision procedures for removal and replacement of cochlear implant electrodes following internal auditory canal insertion are fraught with potential danger, including t...

Hearing preservation after cochlear implantation and combined electric acoustic stimulation (EAS) in the same ear has reduced the gap between prosthetic hearing rehabilitation with hearing aids and cochlear implants. This has increased the possibility of successful hearing rehabilitation for patients. This paper describes the history of hearing preservation after cochlear implantation. Indicati...

BACKGROUND There has been increasing demand for the cochlear implantation of children who demonstrate some auditory capacity with conventional hearing aids. The purpose of this study was to examine speech recognition outcomes in a group of children who were regarded as borderline candidates for cochlear implantation as their residual hearing and/or auditory functioning levels exceeded typical a...
