Abstract

Introduction: A Cochlear implant (CI) is surgically implanted electronic device that provide a sense of
sound to a person with severe to profound sensorineural hearing loss. It helps in social rehabilitation of
the patient with hearing loss. Cochlear implants, like the human hair cell, receive mechanical sound
energy and convert it into a series of electrical impulses. The brain adapts to the new mode of hearing,
and eventually can interpret the electric signals as sound and speech.
Aim: The present study aims to evaluate the outcomes of cochlear implant in terms of hearing and speech
gain, The Department of Otorhinolaryngology of R.N.T. Medical College, Udaipur with patients who
will undergo CI surgery.
Materials and Methods: The prospective study (conducted between June 2016 to December 2018), the
study population in our study were patients attending the Department of ENT in RNT medical college,
Udaipur. A detailed history, including prenatal and perinatal history to assess for risk factors include
TORCH infection and the various parameters that were analyzed like Audiological assessment (BERA,
Otoacoustic Emission testing) duration of deafness, age, sex, type and degree of deafness, lack of benefit
with hearing aids, radiological analysis (HRCT & MRI) of temporal bone and cochlear anatomy for
feasibility for implantation.
Surgically cochlear implanted through Veria technique under all aseptic precautions.
Results: In our study mean age of implantation was 4.851+/-1.265. The mean revised CAP score at pre
op-, 6months, 12months of surgery was 0.5+/-0.5,3.8+/-0.6 and 7.875+/-0.6 respectively; the mean SIR
score at pre-op 6 months, 12 months of surgery was 1.0+/-0.0, 2.2+/-0.4 and 2.5+/-0.5 respectively; the
mean MAIS score at pre op-, 6 months, 12 months of surgery was 1.9+/-1.92, 25.3+/-1.27 and 32.25+/-
0.66 respectively.
Conclusion: Intelligible speech and auditory performance of children who underwent prelingual
cochlear implantation was improved compared to their pre-operative status. Cochlear implantation
appears to be beneficial for pre-lingual deaf children in term of quality of life.
