OBJECTIVE To confirm the clinical efficacy and safety of a direct acoustic cochlear implant. STUDY DESIGN Prospective multicenter study. SETTING The study was performed at 3 university hospitals in Europe (Germany, The Netherlands, and Switzerland). PATIENTS Fifteen patients with severe-to-profound mixed hearing loss because of otosclerosis or previous failed stapes surgery. INTERVENTIO...

Cochlear implant speech processors seek to generate a neural response that mimics normal hearing. However, the cochlear phase response is generally discarded, together with other fine scale temporal aspects of sound. We sought to incorporate and compare a variety of cochlear traveling wave delays (i.e. group delays) in a clinical speech processing strategy. Traveling wave delays resulted in a s...

INTRODUCTION Evaluation of cortical auditory evoked potentials in children with cochlear implants has been proven to be an effective method for assessing cortical maturation after electrical stimulation. OBJECTIVE To analyze the changes in latency values of cortical auditory evoked potentials before and three months after cochlear implant use. MATERIAL AND METHODS This was a case-control st...

BACKGROUND The use of bilateral amplification is now common clinical practice for hearing aid users but not for cochlear implant recipients. In the past, most cochlear implant recipients were implanted in one ear and wore only a monaural cochlear implant processor. There has been recent interest in benefits arising from bilateral stimulation that may be present for cochlear implant recipients. ...

Early activation of Cochlear Implant (CI) is a technique where the processor activated in less than 4 weeks. In this way, time and costs are reduced process functional restoration hearing. On other hand, late sequential cochlear implant one second CI implanted at different surgical first user's age greater 7 years. The aim systematic review to analyze available information on effects early afte...

background and aim: parents’ evaluation of aural/oral performance of children (peach) questionnaire is used for children within any age group and any amount of hearing loss. the pur­pose of this study was translation, cultural adap­tation, determination of reliability and validity of the questionnaire, and assessment of its scores in children with cochlear implant versus normal group. methods: ...

introduction: the feedback provided by auditory apparatus equips normal hearing people with an important controlling mechanism over the speech production processes. the speech of hearing-impaired children is both perceptually and acoustically abnormal. this study tried to compare the formant frequencies of three long vowels in persian-speaking children who used cochlear implant and those who we...
