Abstract

Cochlear implantation (CI) is used for rehabilitation of children with bilateral severe to profound sensorineural hearing loss. Recently, treatment of such children has been influenced by diagnostic technological advances. Infants and toddlers are now increasingly included for CI. The primary aim of this study was to determine the effects of 'age at CI' on CI outcome. The primary aim of this study was to determine the effects of 'age at CI' on CI outcome. In this prospective study at a tertiary care centre, we evaluated 50 cochlear implanted children from October 2011 to March 2013. The case group consists of 15 (30%) children who underwent CI at more than 5 years of age and control group consisted of 35 (70%) children who underwent CI at less than or equal to 5 years age. All patients received auditory and speech rehabilitation and we evaluated their auditory perception outcomes 1 year post CI, the children were assessed by categories of auditory performance (CAP) and meaningful auditory integration scale (MAIS) tests. There were significantly improved mean auditory perception outcomes (increase of 12.29% in CAP, and 14.05% in MAIS scores) at 1 year post CI in CI recipients of age group '5 years or less' in comparison to those...Continue Reading
