Background

Datalogging feature of the cochlear implant audio processor has been utilized to calculate the average daily wearing hours for cochlear implant devices by patients.

Objectives

To assess the relationship between the time use of cochlear implant audio processor and speech development as well as to identify the lowest acceptable duration of audio processor use to achieve an acceptable language development.

Methods

A retrospective study design including prelingual thirty-four ears (24 patients) who received the same electrode array of cochlear implant with 2 years follow up. The audiological and speech evaluations were done for all patients postoperatively and the last postoperative follow-up visit was used for analysis in this study.

Results

The average daily use of the audio processor was 11.3 ± 2.7 h per day. The pure tone average was 30.55 ± 4.64 dB whereas the speech reception threshold was 30.88 ± 6.12 dB. The average speech discrimination score at 65 dB was 68.59 ± 16.80%. A significant positive correlation (r = 0.54, p value = 0.0009) was found between the daily use of the audio processor and the speech discrimination score. The lowest wearing time needed to have more than 60% of the speech discrimination score was 8.3 h/day.

Conclusion

The present study revealed a positive correlation between the daily duration of the audio processor usage and speech performance. Moreover, we found that pediatric patients need to use their cochlear implant device for at least 8.3 h/day to achieve acceptable language development.

人工耳蜗：听力更好，言语表现更好

背景

人工耳蜗音频处理器的数据记录功能已被用于计算患者每天佩戴人工耳蜗设备的平均时间。

目标

评估人工耳蜗音频处理器的使用时间与语言发展之间的关系，并确定音频处理器使用的最低可接受持续时间，以实现可接受的语言发展。

方法

一项回顾性研究设计，包括舌前 34 只耳朵（24 名患者），他们接受了相同的人工耳蜗电极阵列，随访 2 年。术后对所有患者进行听力和言语评估，并在本研究中使用最后一次术后随访进行分析。

结果

音频处理器的平均每日使用时间为每天 11.3 ± 2.7 小时。纯音平均值为 30.55 ± 4.64 dB，而语音接收阈值为 30.88 ± 6.12 dB。65 dB 时的平均语音辨别得分为 68.59 ± 16.80%。在音频处理器的日常使用和语音辨别分数之间发现了显着的正相关（r = 0.54，p 值 = 0.0009）。语音辨别得分超过 60% 所需的最低佩戴时间为 8.3 小时/天。

结论

本研究揭示了音频处理器使用的每日持续时间与语音性能之间存在正相关关系。此外，我们发现儿科患者需要使用人工耳蜗装置至少 8.3 小时/天才能达到可接受的语言发展。
