To compare speech perception performance with right versus left cochlear implants (CIs) in children with bilateral CIs implanted simultaneously.

Prospective case series of patients undergoing simultaneous bilateral cochlear implantation.

Speech perception performance was tested in 10, right‐handed children who received bilateral CIs simultaneously between 11 and 36 months (mean, 21 months), had at least 18 months of bilateral CI use, and were 5.3 years of age during testing. All children exhibited bilateral symmetrical severe‐to‐profound hearing loss prior to implantation and did not benefit from hearing aids. Speech perception performance was evaluated with the right CI and the left CI by means of an open‐set monosyllabic word test in quiet presented at 45 dB HL in a sound field.

All children exhibited higher performance with the right CI compared …
