The outcomes of bilateral cochlear implant users in Universiti Kebangsaan Malaysia

Abstract

Introduction

Bilateral cochlear implants are seen to improve hearing capabilities.

Objective

To assess the auditory outcome of paediatric bilateral cochlear implant in Universiti Kebangsaan Malaysia.

Materials and methods

This was a cross-sectional and descriptive study single centre analysis. Categories of Auditory Performance (CAP-II) scale and Speech, Spatial and Qualities (SSQ) of Hearing questionnaire were used.

Results

Forty-six patients were recruited. Majority of the children (30.4%) rated 7 and 23.9% scored perfectly (9) based on the CAP-II Scale. The least performing children were rated 5 (average). Children that were implanted sequentially within 24 months showed median CAP-II scale of 7. No significant correlation seen between CAP-II and the duration interval, use and age of 1st CI (p > .05). The speech domain of SSQ-P scale showed median value of 8 indicating good speech understanding. The spatial hearing domain had median value of 7, quality of hearing domain had median of 8. Significant correlation seen in hearing in noise with the duration of use of CI (p < .05).

Discussion

Bilateral CI have shown benefits in auditory performance even though majority were performed sequentially. Promising outcome was better with prolonged usage of the device.

Conclusion

Hearing in noise is significantly better in bilateral CI.

简介：双侧人工耳蜗可以提高听力。

目的：评价马来西亚Kebangsaan大学的儿童双侧人工耳蜗植入术的听觉效果。

材料与方法：采用单中心横断面描述性研究。采用了听觉表现分类（CAP-II）量表与言语、空间和品质（SSQ）的听觉问卷调查法。

结果：共招募46例患者。基于CAP-II标度, 大多数儿童（30.4%）的评分为7分, 23.9% 为满分（9）。表现最差的孩子为5分（平均）。24个月内连续植入的儿童的CAP-II中位评分为7。无重大意义CAP-II与第1次CI的持续时间、使用时间和年龄相关（p>0.05）。SSQ-P量表的语言阈中位数为8, 表明语音理解良好。空间听阈中位数为7, 听阈质量中位数为8。噪声听力与CI使用时间显著相关（p<0.05）。

讨论：尽管多数是按顺序进行的, 但双侧CI在听觉表现方面显示出优势。长期使用该装置, 效果更佳。

结论：双侧CI植入患者的噪声听力明显优于对照组。
