Description
Post-lingual deaf adults can develop some vocal abnormalities similar to those developed in prelingual deaf individuals. The aim of this work was to study the eVect of cochlear implantation followed by postoperative rehabilitation on voice acoustics in post-lingual hearing impaired adults with diVerent 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 signiWcant improvement in their MDVP results postimplantation. Further, signiWcantly deviant MDVP parameters were reported in the group of patients with longer duration of hearing loss. Patients who received rehabilitation signiWcantly 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.
