ABSTRACT The bilateral cochlear implant
has increased in recent years in due to the search for auditory enhancements.
There are many advantages to the users of the bilateral cochlear implant, which
may include the location of the auditory sign, decreasing the head shadow effect
for the contralateral ear and binaural summation of the hearing. In children it
is also discussed the issue of auditory deprivation. The aim of this review was
to present a reflection on issues related to the bilateral cochlear implant,
allowing the reader to do a search and strengthen scientifically with this
issue, giving theoretical foundation to better guide and advise their
