Abstract To determine whether variables such as Age, Gender, Demographic background of the patient and Preoperative usage of hearing aids affect the outcomes of pediatric cochlear implant surgery when modified; in terms of speech and hearing gain. A hospital based retrospectiveprospective type of cohort study was conducted over a period of 5 years at a Tertiary care Teaching hospital and referral centre covering a population of about 68.9 million. Candidates selected were 1–5 years of age with bilateral congenital severe-profound sensori-neural hearing loss. 50 patients were selected and were operated using VERIA technique of Cochlear Implant Surgery. Intraoperative testing of electrode functioning was done in all patients using NRT technique. The switching on of implant was done after 1 month, following which patients underwent 100 sessions of auditory verbal therapy and training. Outcomes were evaluated in terms of hearing and speech gain by using Revised CAP scores, ITMAIS scores and PEACH scores in the loco-regional language. Those implanted at a younger age and with at least 3 months of hearing aid usage pre-operatively had better outcomes measures.

was no effect on outcomes when the gender and demographic origin of the patient were compared. Candidates implanted before 3 years age give better results and they should be encouraged to use hearing aid regularly and continuously before the surgery and should be advised trial and fitting as soon as CI planning begins. Also, gender and demographic background should not be considered when planning CI as these have no significant effect on outcomes. Keywords Cochlear implants Deaf and mute CAP PEACH IT-MAIS
Introduction A recent WHO estimate suggests that world-wide approximately 466 million people (or 6.1% of the world’s population) are living with disabling hearing loss as in 2018. This estimate is projected to rise to 630 million by 2030 and to over 900 million by 2050. Approximately 90% of people with moderate to profound hearing impairment reside in low- and middle-income countries [1]. (Tables 1, 2, 3, 4 and 5). For many, hearing aids provide a viable solution, but if one experiences significant hearing loss, hearing aids may offer little or no benefit. This is where cochlear implants (CI) come into role. A cochlear implant is a hearing prosthesis designed to restore or provide a level of audit
