OBJECTIVE The benefits of cochlear implantation for children with developmental delays (DD) often are unclear. We compared cognition, adaptive behavior, familial stress, and communication in children with and without DD. STUDY DESIGN Retrospective review. SETTING Two tertiary care pediatric hospitals. PATIENTS Two hundred four children who underwent cochlear implantation assessed before a...

BACKGROUND Hearing Preservation is becoming increasingly important in cochlear implantation as there is growing evidence that preserving the residual hearing, especially in the low frequencies in combination with the electric stimulation can significantly improve hearing and speech outcomes in noise. Besides the ongoing development of atraumatic implant electrodes and insertion techniques, the ...

OBJECTIVE Age is one of the most important determinants of the benefit achieved in the cochlear implantation of pre-lingually deafened children. Earlier age at implantation increases the exposure of children with a hearing impairment to auditory stimuli. Earlier auditory stimulation enables children to better understand spoken language and to use spoken language themselves. Furthermore, there a...

OBJECTIVES Cochlear implantation influences not only communication but also psychosocial outcomes in children with severe to profound hearing loss. Focusing on issues specific to cochlear implantation (e.g., self-reliance, social relations, education, effects of implantation, and supporting the child) may provide a more accurate and relative view of functional status of pediatric cochlear impla...

Clinical application of mutation screening and its effect on the outcome of cochlear implantation is widely debated. We investigated the effect of mutations in GJB2 gene on the outcome of cochlear implantation in a population with a high rate of consanguineous marriage and autosomal recessive nonsyndromic hearing loss. Two hundred and one children with profound prelingual sensorineural hearing ...

BACKGROUND The benefits of bilateral cochlear implantation in the pediatric population include better sound localization, benefits with speech in noise, and improved language development. In the pediatric patient who meets the criteria for bilateral cochlear implantation, should the surgeries be performed simultaneously or sequentially? If sequentially, what is the best timing? The importance o...

IMPORTANCE The association between hearing impairment and cognitive decline has been established; however, the effect of cochlear implantation on cognition in profoundly deaf elderly patients is not known. OBJECTIVE To analyze the relationship between cognitive function and hearing restoration with a cochlear implant in elderly patients. DESIGN, SETTING, AND PARTICIPANTS Prospective longitu...

Background: Cochlear implantation is an efficient treatment for postlingually deafened adults who do not benefit sufficiently from acoustic amplification. Implantation indicated when it can be foreseen that speech recognition with a cochlear implant (CI) superior to hearing aid. Especially subjects residual recognition, desirable predict CI outcome on the basis of preoperative audiological test...

OBJECTIVE This study aimed to evaluate the long-term speech perception and speech intelligibility of congenitally and prelingually deaf children after cochlear implantation. It was a longitudinal study following 63 congenitally or prelingually deaf children up to 5 years after implantation. They each received a nucleus multichannel cochlear implant before they were 10 years old. METHODS Perce...

HYPOTHESIS Histopathologic study of the tissue seal and biologic response around cochlear implant electrodes in patients who had received a cochlear implant during life could provide clues concerning the pathogenesis of meningitis after cochlear implantation. BACKGROUND Bacterial meningitis has been reported as an infrequent complication of cochlear implantation using a variety of electrode d...
