Abstract：Objective To evaluate the postoperative outcomes of cochlear implant recipients with Auditory neuropa-thy (AN) of severe or profound hearing impairment. Methods The pure-tone audiometry,Categories of Auditory Perfor-mance(CAP),Speech Intelligibility Rating(SIR), Meaningful Auditor Integration Scale(MAIS)were performed in 18 prelin-gually deafened patients with AN of severe or profound hearing impairment and 4 post-lingually deafened patients with AN of severe or profound hearing impairment after cochlear implantation.The outcomes were compared between patients with AN and with non-syndromic congenital deafness. Results The average aided hearing thresholds of 11 AN patients af-ter cochlear implantation were 38.64±6.36 dB HL. There was no significant difference in scores at vocalization behaviour and spontaneous alerting to sound between AN and non-syndromic prelingually deafened patients after cochlear implanta-tion (P>0.05).There was significant difference in scores at deriving meaning from sound and MAIS between AN and non-syndromic prelingually deafened patients after cochlear implantation(P>0.05).The scores at deriving meaning from sound and MAIS of AN prelingually deafened patients after cochlear implantation were significantly lower than those of non-syndormic hearing-impaired prelingually deafened patients after cochlear implantation.There was no significant differ-ence in scores in CAP,SIR between AN and non-syndromic hearing-impaired post-lingually deafened patients after cochle-ar implantation(P>0.05). Conclusion The AN prelingually deafened patients with severe or profound hearing impairment and non-syndromic hearing-impaired patients show no significant difference in abilities of vocalization behaviour and spontaneous alerting to sound. The abilities of deriving meaning from sound of AN prelingually deafened patients after co-chlear implantation were significantly lower than those of non-syndormic hearing-impaired prelingually deafened patients after cochlear implantation.There is no significant difference in auditory and speech abilities between AN and non-syndrom-ic hearing-impaired post-lingually deafened patients after cochlear implantation.
