Cochlear implant devices are designed to provide sound sensation and improved speech understanding to people who are profoundly hearing impaired. Best speech recognition could be achieved by using multi-channel, multi-electrode cochlear implant devices. In a multichannel cochlear prosthesis, channel interaction and tissue damage are important issues to be solved. Speech processing and modidatio...

This paper investigates suprasegmental features in the prelexical speech of congenitally hearing impaired children who received a Nucleus-24 multichannel cochlear implant between 5 and 20 months of age. Bi-syllabic spontaneous babbling productions were analyzed acoustically at different stages in the babbling period. Fundamental frequency, pitch change in terms of direction and degree, and dura...

OBJECTIVE To assess the effect of sequential bilateral cochlear implantation in children on their quality of life (QoL). DESIGN Prospective cohort-control study. SETTING Tertiary academic referral center. PATIENTS Thirty children with prelingual deafness underwent sequential bilateral cochlear implantation (mean age at first implant, 1.8 years; mean age at second implant, 5.3 years). Nine...

BACKGROUND The occurence of cholesteatoma and cochlear implant is rare. Secondary cholesteatomas may develop as a result of cochlear implant surgery. Primarily acquired cholesteatoma is not typically associated with congenital sensorineural hearing loss or cochlear implant in children. The occurrence of congenital cholesteatoma during cochlear implant surgery has never been reported before, par...

Introduction: Parents are such important members of the cochlear-implant team that analysis of their views is essential in orderto improve services and outcomes. The authors developed a tool to assess parental attitudes towards various aspects of cochlear implantation in children who had passed aural rehabilitation sessions. The authors then went on to determine the validity and reliability of ...

It is still largely unknown how receiving a cochlear implant affects the emotion understanding in deaf children. We examined indices for emotion understanding and their associations with communication skills in children aged 2.5-5 years, both hearing children (n = 52) and deaf children with a cochlear implant (n = 57). 2 aspects of emotion understanding were examined: (a) emotion recognition in...

Introduction Middle fossa approach has been suggested as an alternative for patients in whom other routes of electrode insertion are contraindicated. Even though there are temporal bone studies about the feasibility of introducing the cochlear implant through the middle fossa, until now, very few studies have described results when cochlear implant surgery is done through this approach. Objecti...

OBJECTIVES/HYPOTHESIS To evaluate the effectiveness of bilateral cochlear implantation over unilateral implantation in children with sensorineural hearing loss. DATA SOURCES Pubmed, Embase, and Web of Science. REVIEW METHODS All studies comparing a bilateral cochlear implant group with a unilateral implant group were included. RESULTS Twenty-one studies compared a bilateral cochlear impla...

OBJECTIVES With rising quality of speech perception in cochlear implant users, the indication widens. Nowadays, cochlear implantation is reasonable even in vestibular schwannoma patients. Speech perception with a cochlear implant is in these patients as promising as in patients with sensorineural hearing loss. However, the impact of cochlear implantation on vertigo and tinnitus after removal of...
