Studies on children with sequential bilateral implantation has shown that these children may have the possibility to take an advantage
of the binaural benefits of normal-hearing individuals. However, reports are limited by concerns about the number of patients and the
observation times. In our study we included prelingually deaf children with sequential bilateral cochlear implantation assessed at both 12
and 24 months postoperatively to the second implantation.We evaluated the effect of bilateral versus unilateral cochlear implants and the
importance of the inter-implant interval (time between the first and the second implantation) on speech recognition and sound localisation
performance. Seventy-three children was tested using monosyllabic words in quiet conditions and 63 children performed the five-speaker
sound localisation test. Percent correct word perception, mean angular error (MAE) and correct speaker score (CSS) was calculated The
mean bilateral speech recognition 12 and 24 months after the second implantation was significantly higher than that obtained with either
the first or the second implant alone. The overall improvement (both 12 and 24 months postoperatively the second implantation) in the
MAE with two cochlear implants compared with one cochlear implant was 10.18 %. After 12 months with bilateral CIs, the difference
in CSS between listening in a unilateral (mean CSS = 29%) condition and listening in bilateral (mean CSS = 30%) condition was small,
however a significant difference was seen after 24 months, mean bilateral CSS 38%. A shorter inter-implant interval was associated with
better bilateral speech recognition and sound localising performance.
