Evaluation of Speech Perception Skills after Unilateral Cochlear Implantation in 45 Pre Lingual Deaf Patients
Journal Title: International Journal of Science and Research (IJSR) - Year 2013, Vol 2, Issue 1
Abstract
Under B.J. Medical College Cochlear and Hearing Implant Programme 45 prelingual deaf patients who underwent unilateral Cochlear Implantation were selected and divided into five groups on basis of age at which participants underwent implantation: ≤3 years, 3 to 6 years, 6to 9 years, 9 to 12 years, and 12 to15 years. Speech perception skills were assessed using phonetically balanced Hindi word list before implantation and at specified post-implant switch-on time periods for upto 2 years. The scores increased significantly in all five groups from pre- to post- CI in every follow-up. Positive effect of time was seen with better results in those implanted at younger age.
