Abstract

Objectives: The aim of this study is to compare the outcome of cochlear implantation in two pediatric auditory neuropathy cases. Methods: Two cases with auditory neuropathy were taken. Case 1 was 10 year old male. Case 2 was 11 year old male. In preoperative assessment both have bilateral severe to profound sensory-neural hearing loss. Case 1 was implanted by MED-EL using sonata Ti100 opus 2 processor. Case 2 was implanted using MED-EL using sonata Ti100 opus 2 processor. Both cases were given auditory verbal therapy. Both cases attended auditory verbal therapy for a period of 2 years. In postoperative assessment for each individual subject, electrically evoked compound action potentials (ECAPs), electrically evoked stapedius reflex threshold (ESRT), and electrically evoked auditory brainstem response (EABR) thresholds were determined. The following questionnaire extended receptive expressive emergent language scale (E-REELS) , Categories of Auditory Performance (CAP) score, Speech Intelligibility Rating (SIR) scale, Meaningful Auditory-Integration Scale (MAIS) and Meaningful Use of Speech Scale (MUSS) are scales were administered. Results: In the postoperative assessment, ECAP, ESRT, EABR, MUSS, MAIS shows that case 1 with auditory neuropathy have better performance than case 2. Conclusion: It is essential that all possible complications and postoperative performance should be considered in cochlear implantation for auditory neuropathy individuals
