Cochlear Implant (CI) is the most advanced method of treatment in receptive type of deafness and profound hearing loss. Good functioning auditory organ plays a significant role not only in auditory perception but also in the process of phonation, giving the possibility of good realization of the process of verbal communication. The aim of the study is to assess the quality of voice and life in adults with pre- and postlingual deafness treated using cochlear implant.
Twenty six patients with pre- (group I) and postlingual (group II) deafness deriving no benefit from hearing aids were included into the study. Voice quality was assessed using subjective and objective methods. The endoscopic (VLS) and stroboscopic (VLSS) examination of the larynx and the acoustic voice analysis were carried out. The quality of life was assessed using the Nijmegen Cochlear Implant Questionnaire (NCIQ). Examinations were conducted before implantation and 6 months after activation of speech processor.
In the subjective and objective assessment of voice quality the improvement was registered in both groups. The effects were less spectacular in prelingual patients. In this group of patients the subjective assessment of voice quality and stroboscopic examination confirmed the hypofunctional type of dysphonia. In postlingual patients the hyperfunctional type of dysphonia was registered what was confirmed by the analysis of acoustic parameters of voice. The improvement of quality of life was observed in both groups of patients after implantation.
The voice quality was improved after implantation in both analyzed groups. In patients with postlingual deafness values of parameters of voice quality assessment were closed to physiological. Results of the subjective assessment of voice quality were confirmed by objective examinations and the acoustic voice analysis. Rehabilitation with cochlear implant gave the opportunity for active participation in private and social life, improving the quality of life in patients with pre- and postlingual deafness.
人工耳蜗（CI）是感音神经性耳聋和极重度听力损失最先进的治疗方法。功能良好的听觉器官不仅在听觉感知中起重要作用，而且在发声过程中也起重要作用，使言语交流过程得以良好实现。本研究的目的是评估使用人工耳蜗治疗的语前聋和语后聋成人的嗓音质量和生活质量。
本研究纳入了26例使用助听器无效的语前聋（I组）和语后聋（II组）患者。采用主观和客观方法评估嗓音质量。对喉部进行了内镜（VLS）和频闪喉镜（VLSS）检查以及嗓音声学分析。使用奈梅亨人工耳蜗问卷（NCIQ）评估生活质量。在植入前和言语处理器激活6个月后进行检查。
在嗓音质量的主观和客观评估中，两组均有改善。语前聋患者中的效果不太显著。在这组患者中，嗓音质量的主观评估和频闪喉镜检查证实为发声功能减退型发音障碍。在语后聋患者中，记录到发声功能亢进型发音障碍，这通过嗓音声学参数分析得到证实。两组患者植入后生活质量均有改善。
在两个分析组中，植入后嗓音质量均有改善。在语后聋患者中，嗓音质量评估参数值接近生理值。嗓音质量主观评估结果得到客观检查和嗓音声学分析的证实。人工耳蜗康复使患者有机会积极参与个人和社会生活，提高了语前聋和语后聋患者的生活质量。
