Abstract

Purposes

The objective of this research was to interpret and analyze the imaging, audiological features and cochlear implantation outcomes in cochlear nerve deficiency children.

Material and methods

Retrospective analysis.

Results

25 prelingual hearing loss children diagnosed cochlear nerve deficiency (CND), the age range from 1 to 15 (mean age, 5.04), underwent cochlear implantation at Ear Nose and Throat Hospital - Ho Chi Minh City (ENT hospital – HCMC) from 2016 to 2023. All children had sensorineural hearing loss (SNHL) from severe to profound degree. Magnetic resonance imaging (MRI) showed cochlear nerve hypoplasia in 76 % and cochlear nerve aplasia in 24 % of cases. Inner ear malformations were found in 52 % of cases. The mean Categories of Auditory Performance (CAP) score at 1 year after surgery was 4.8. At 6 months and 1 year after surgery, the mean CAP score of the aplasia group was significantly lower than that of the hypoplasia group (p < 0.05).

Conclusions

In cochlear nerve deficiency children, auditory perception and speech performance still improved after cochlear implantation. However, this progress was significantly limited in cochlear nerve aplasia group.

人工耳蜗植入对耳蜗神经缺失儿童的疗效 - 一项单中心研究

材料和方法回顾性分析。结果25名被诊断为耳蜗神经缺损（CND）的舌前听力损失儿童，年龄从1岁到15岁（平均年龄5.04岁），于2016年至2023年在胡志明市耳鼻喉科医院（ENT hospital - HCMC）接受了人工耳蜗植入手术。所有儿童均患有重度至极重度感音神经性听力损失（SNHL）。磁共振成像（MRI）显示，76%的病例耳蜗神经发育不良，24%的病例耳蜗神经发育不全。52%的病例存在内耳畸形。术后 1 年的听力表现分类 (CAP) 平均得分为 4.8 分。手术后 6 个月和 1 年时，增生组的平均 CAP 评分明显低于发育不良组（P < 0.05）。结论：人工耳蜗植入后，听觉感知和语言表达能力仍有改善，但人工耳蜗神经缺失组的改善明显受限。
