摘要
目的进行言语识别率测试和助听效果评估调查问卷(COSI问卷)初步评价信号对传式(contralateral routing of sound,CROS)助听器应用于单侧聋患者的助听效果。方法20例单侧聋患者进行助听后效果评估,分别进行CROS助听器干预前后安静环境下和噪声环境下言语测试、噪声下言语识别速测表(Quick SIN)以及助听6周后患者导向听觉改善分级(client oriented scale of improvement,COSI)问卷评估。结果患者安静环境、SNR=5dB、SNR=10dB时,佩戴CROS助听器言语识别率与未佩戴相比差异有统计学意义(P<0.001);信噪比为0 dB时,无显著性差异(P=0.242);20例患者中,12人有无佩戴CROS助听器的SNR Loss比较,有显著性差异(P<0.001);8人有无佩戴CROS助听器的SNR Loss比较,未见显著性差异(P=0.095)。助听6周后随访患者最终能力评分≥4分者占77%,最终能力评分与自觉改善程度基本一致,CROS助听器对大部分患者在特定情境中交流舒适度有显著改善。结论安静环境下单侧聋患者能通过使用CROS助听器显著受益;噪声环境下信噪比越高,使用CROS助听器获益越明显。
Objective To evaluate the effects of contralateral routing of sound(CROS)hearing aid in patients with unilateral hearing loss by speech recognition and client oriented scale of improvement(COSI).Methods Speech recognition and Quick-SIN were evaluated in quiet and noise environment before and after CROS hearing aid intervention in 20 patients with unilateral deafness,and COSI after 6 weeks of hearing aid usage.Results In quiet environment and at signal-to-noise ratio(SNR)=5 dB and SNR=10 dB,speech recognition score in patients wearing CROS was significantly higher than that in patients without CROS(P<0.001)but showed no significant difference when SNR was 0 dB(P=0.242).SNR loss with and without CROS was significantly different in 12 patients(P<0.001)and not so in the rest 8 patients(P=0.095).At 6 weeks follow-up,77% of the patients had a final ability score≥4,basically consistent with subjectively reported improvement.CROS hearing aid significantly improved communication comfort in most patients in specific situations.Conclusion Patients with unilateral deafness can benefit significantly from using CROS hearing aid in quiet environment.In noise,the benefits increase as the signal-to-noise ratio increases.
