Bilateral versus unilateral cochlear implantation in young children

Verbal Cognition in Deaf Children Using Cochlear Implants: Effect of Unilateral and Bilateral Stimulation

“…Open-set speech recognition scores correlate significantly with measures of speech production and language [Tait et al, 2010]. Several studies reported significant mutually related improvements in auditory, speech, and vocabulary development but not in the development of more complex language performance [Svirsky et al, 2004;Geers et al, 2008;Archbold, 2010;De Raeve, 2010;Sparreboom et al, 2010;Boons et al, 2012Boons et al, , 2013.…”

Language development in children after receiving bilateral cochlear implants between 5 and 18 months

“…A few recent studies show that bilateral cochlear implantation is important for auditory development and function [13][14][15][16]. Tait et al [17] found that children with two CIs used significantly more audition and vocalization in communication after 12 months of CI use than unilaterally implanted children.…”

Cochlear Implants in Children: A Review

“…A recent study comparing the preverbal communication of children implanted before age 3 years (27 bilaterally; 42 unilaterally) reported that children with bilateral cochlear implants were significantly more likely to use vocalisation to communicate and to use hearing when interacting with an adult than were children with unilateral implants (Tait et al, 2010). After statistically controlling for the influence of age at implantation and length of deafness, it was found that bilateral implantation contributed to 51% of the variance in outcomes.…”
