Abstract:
Objective To study the effect of auditory and speech development after cochlear implant(CI)in children with bilateral cochlear nerve deficiency(CND)and its influencing factors.Methods A total of 20 children with bilateral CND were included in the study,of which 5 were implanted bilaterally and 15 unilaterally.CT of the temporal bone showed stenosis of the cochlear aperture in 14 cases and atresia of the cochlear aperture in 6 cases.There were 8 cases accompanied by other inner ear malformations,and 12 cases with no accompanying inner ear mal-formations.MRI of the internal auditory canal showed 1 nerve in 5 cases,2 nerves in 6 cases,3 nerves in 8 cases,and 4 nerves in 1 case.There were 6 cases in which the EABR was not elicited and 14 cases in which it was elicited.The postoperative auditory and speech abilities of the subjects were evaluated using categories of auditory perform-ance(CAP)and speech intelligibility rating(SIR).Results ① The CAP(P＜0.001)and SIR(P＜0.001)scores of the children with stenosis of the cochlea nerve canal were higher than those of the patients with atresia of the cochlea nerve canal.② The more nerve roots in the internal auditory canal,the higher the score of CAP(P=0.003)and SIR(P=0.008).③ CAP score of the children with EABR elicited was higher than that of the children without EABR elicited(P=0.030).The difference in SIR scores was not statistically significant(P=0.14).④The differences in CAP and SIR between those with bilateral CI and unilateral CI,as well as between those with and without other inner ear malformations,were not statistically significant(P＞0.05).Conclusion Children with bi-lateral CND had significant postoperative improvement in auditory function but poor speech development after CI.Postoperative auditory speech ability was related to the condition of the cochlear foramen,the number of nerve roots in the internal auditory canal,and whether or not the EABR was elicited intraoperatively.
