单侧聋人工耳蜗植入长期随访1例

A Case of Long Term Follow up of Cochlear Implantation Sided Deafness Patients

目的探讨单侧聋(single-sided deafness,SSD)成人患者人工耳蜗植入远期效果。以为单侧聋患者人工耳蜗植入适应症提供借鉴和参考。方法选择一例单侧聋20年成人进行人工耳蜗植入,随访其残余听力、言语识别率、声源定位能力、以及言语空间和听觉质量主观量表(SQQ)。结果该患者术后残余听力早期保持良好,但五年后残余听力未能保留。言语识别率随术后随访时间延长而有所提升,但没达到较高水平。声源定位能力随时间有所改善。随访SQQ量表可以看出SSD患者人工耳蜗植入后对于言语理解、空间听觉、声音聆听能力都有所帮助,尤其对于空间听觉帮助较大。结论SSD患者人工耳蜗植入后,可以改善患者噪声下的言语识别率与声源定位能力及生活质量。建议进一步大样本研究,为SSD患者人工耳蜗植入适应症提供科学依据。

Objective To investigate the long-term effects of cochlear implantation in adult patients with single-sided deafness(SSD).To provide reference for the indications of cochlear implantation in patients with SSD.Methods An adult with SSD for 20 years was selected for cochlear implantation and followed up on residual hearing,speech recognition rate,sound source localizability,and subjective scale of speech spatial and auditory quality(SQQ).Results The patient's residual hearing remained good early on but was not preserved after five years.Speech recognition rates improved with longer follow-up after surgery,but did not reach a high level.Sound source localizability has improved over time.Follow-up SQQ scale shows that cochlear implantation in SSD patients is helpful for speech comprehension,spatial hearing,and sound listening ability,especially for spatial hearing.Conclusion After cochlear implantation in SSD patients,it can improve the speech recognition rate,sound source localization ability and quality of life of patients under noise.Further large studies are recommended to provide a scientific basis for the indication for cochlear implantation in SSD patients,to provide scientific basis for the indications for cochlear implantation in SSD patients.
