Background: Cochlear implant (CI) for rehabilitation of children with bilateral severe to profound sensorineural hearing loss represents the initial use of electrical fields to provide auditory perception in cases where sound amplification does not provide satisfactory results. Aims: To study effect individual factor of “Presence or absence of an associated comorbidity” on auditory perception outcomes on CI recipient children. Study design: Prospective study Setting: Tertiary care centre Methods: During the period from October 2011 to March 2013 cochlear implantation was performed on 50 children with bilateral severe to profound sensorineural hearing loss under 10 yrs of age. History in terms of any other comorbidities in the child was noted. Auditory perception outcomes (CAP & MAIS) was measuredpreoperatively, and 3, 6, 9 & 12 months after CI surgery. Auditory perception in these children was studied in relation to the patient variable of comorbidities (whether Present/Absent). Chi square test was used for statistical analysis. Results: There were improved mean auditory perception outcomes (increased 9.15% CAP, 14.14% MAIS) in cochlear implant recipients who had no comorbidities, in comparison to those who had an associated comorbidity. Conclusion: In this study of auditory perception assessment of 50 children with Profound hearing losses, presence of comorbidities was found to have a deleterious effect on auditory perception outcome and this result has been found to be statistically significant for MAIS and not significant for CAP scores. Hence it is safe to conclude that knowledge of “Presence or absence of an associated comorbidity” can provide reasonable help in predicting the auditory perception and hence spoken language outcomes for individual CI candidates.
