Post-lingual deaf adults can develop some vocal abnormalities similar to those developed in pre-lingual deaf individuals. The aim of this work was to study the effect of cochlear implantation followed by post-operative rehabilitation on voice acoustics in post-lingual hearing impaired adults with different durations of hearing loss. The study included 35 post-lingual hearing impaired adults who underwent cochlear implantation. Patients were divided into two groups according to the duration of their hearing loss. Each group was further divided into two subgroups according to whether they received auditory rehabilitation or not. Using the Multi-Dimensional Voice Program (MDVP) parameters, comparisons were made between each subgroup of patients and the normal MDVP Saudi database, and between subgroups of patients. Most of the patients in the two groups reported significant improvement in their MDVP results post-implantation. Further, significantly deviant MDVP parameters were reported in the group of patients with longer duration of hearing loss. Patients who received rehabilitation significantly improved more than those who did not. In conclusion, it appears that cochlear implantation improves the auditory control of voice production in post-lingual deaf adults. Also, it is obvious that cochlear implantation at an early stage of hearing loss gives better results on voice control, especially if augmented with auditory rehabilitation.
后天失聪的成年人可能会出现一些与先天失聪者类似的发声异常。本研究旨在探讨人工耳蜗植入术后康复对不同耳聋时间的后天失聪成年人嗓音声学的影响。本研究纳入了 35 名后天失聪的成年人，他们均接受了人工耳蜗植入。根据耳聋时间的长短，患者被分为两组。每组进一步根据是否接受听觉康复分为两个亚组。通过多维语音程序（Multi-Dimensional Voice Program，MDVP）参数，将患者的每个亚组与正常的沙特 MDVP 数据库以及患者的亚组之间进行比较。两组患者的大多数报告了植入后 MDVP 结果的显著改善。此外，在耳聋时间较长的患者组中，报告了明显异常的 MDVP 参数。接受康复治疗的患者比未接受康复治疗的患者改善更为显著。总之，人工耳蜗植入似乎可以改善后天失聪成年人对嗓音产生的听觉控制。此外，在听力损失的早期阶段进行人工耳蜗植入对嗓音控制的效果更好，特别是如果结合听觉康复。
