RESUMEN
This study was performed to investigate the effect of cochlear implantation on the Quality of Life (QoL) of children with profound and multiple learning disability (PMLD). This cohort of children has been viewed historically as poor candidates for cochlear implantation as they generally have poor speech and hearing outcomes. The Irish National Cochlear Implant Program's prospectively maintained database was examined for all children implanted from July 1996 to July 2015. All charts of the 381 children implanted during this time were reviewed retrospectively; 16 children met criteria for being PMLD. For this cohort of patients, speech and hearing performance and the Glasgow Children's Benefit Inventory scores were retrospectively analyzed. Speech and hearing outcomes, as measured by Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) scores, demonstrated little or no improvement from pre-implantation to an interval 3 years post-op; however, 11 out of 16 parents reported an improvement in their child's quality of life after implantation with 3 out of 16 reporting no improvement. This study suggests that despite children with PMLD performing poorly on traditional outcome measures such as CAP and SIR they may have improvement to their QoL after cochlear implantation. Further study is warranted to characterize the impact of CI on these children.
