Abstract
It became generally accepted and agreed on that BiCI more beneficial
than unilateral CI. Most of the authors support that BiCI outcome measures
suggest benefits of sound localization, hearing better in noisy environments, and
quality of life in addition to facilitation of language acquisition, learning,
cognition and memory rather than unilateral hearing. Although their
performance is not at the level of normal-hearing listeners.
According to European Bilateral Pediatric Cochlear Implant Forum
Consensus Statement “ the infant or child with unambiguous cochlear implant
candidacy should receive Bilateral Cochlear implants simultaneously as soon as
possible after definitive diagnosis of deafness to permit optimal auditory
development: with an atraumatic surgical technique designed to preserve
cochlear function, minimize cochlear damage, and allow future easy possibly
repeated re-implantation”.
Benefits of BiCI measures widely variables among patients. Optimization
of Binaural hearing not bilateral hearing is the guideway to achieve best
benefits outcomes. To ensure the maximal potential for binaural processing, the
reported age with maximum potential advantages of early plasticity and an
optimum binaural benefit is during the first 3.5 years of life. There is some
variability in the data between the ages of 3.5 to 7 years. In addition to the
candidates have the Post-lingual onset of hearing loss, relatively short duration
of profound hearing loss (e.g. less than 15years), or consistent and continued use
of amplification in both ears until implantation.
Simultaneous BiCI promotes the development of bilateral auditory
Pathway in tandem and is less resource consuming for rehabilitation compared
with sequential bilateral implantation in children. Although, there is
accumulating evidence for simultaneous bilateral and sequential bilateral with
short inter-implant delays less than 12 months compared with the sequential
bilateral implant with longer inter-implant delays more than 12 months.
