Range of auditory1

• The Greenwood function is species-dependent and has shown to be preserved in mammals when normalized to the species-dependent range of auditory frequencies and cochlear spiral length (Greenwood 1990). (wikipedia.org)

Congenital2

• The last case had cochlear implantation in the ear with congenital aural atresia. (pubfacts.com)
• This study addressed the efficiency of cochlear implantation in cases of Seckel syndrome, complete atrioventricular block managed with cardiac pacemaker, congenital aural atresia and posterior fossa arachnoid cyst. (pubfacts.com)

Deaf children2

• The FDA's original approval of implantation in prelingually deaf children was granted without full benefit of information on language acquisition, on childcaregiver communication, and on the lived experience of being deaf. (springer.com)
• We call for the FDA (and similar agencies in other countries) to review its approval of cochlear implantation in prelingually deaf children who are within the sensitive period for language acquisition. (springer.com)

Procedure3

• Unlike natural hearing, the cochlear implant uses digital, electronic signals, demanding adequate cognitive function, which is an important factor during the patient selection procedure. (springermedizin.de)
• Both POD and POCD can postpone the start of rehabilitation after a cochlear implantation and influence the efficiency of the procedure. (springermedizin.de)
• Although cochlear implantation has been almost a standard otological procedure worldwide, it may still create a dilemma for the surgeon in some unusual instances such as Seckel syndrome, aural atresia and posterior fossa arachnoid cyst. (pubfacts.com)
