    Abstract:
    UNLABELLED: Cochlear Implant (CI) is the most advanced technical solution in the treatment of profound hearing loss and deafness in patients of all age groups. The aim of the study was to analyse the speech and linguistic disorders in adults with pre- and postlingual deafness rehabilitated with Cochlear implant (CI). MATERIAL AND METHODS: 21 adults with pre- (I group) and postlingual (II group) deafness deriving no benefit from hearing aids participated in this study. Phonatory organ was examined by endoscopy (VLS) and stroboscopy (VLSS). Test of Auditory Perception (TSS) was conducted directly after the activation of speech processor and after rehabilitation. The logopedic assessment before and after CI was based on the examination of motoric activity of articulatory organs, type of respiration, loudness of speech and the assessment of articulation. The linguistic assessment of grammatical and lexical aspect was carried out. The prosodic elements of speech were also analysed. RESULTS: Stroboscopic examination pointed to hypofunction of larynx in patients with prelingual deafness and hyperfunction--in postlingual deafness. The values of TSS were improved after CI, especially in patients with postlingual deafness. The most severe disorders of the efficiency of articulatory organs were observed in patients with prelingual deafness before CI. In the group of prelingually deaf patients disorders of the articulation of vowels and consonants as well as the lexical and grammatical aspect of speech were improved after CI. The correctness of syntax and inflection, development of active vocabulary, improvement of prosodic elements of speech were noticed in patients with postlingual deafness after CI. CONCLUSIONS. Patients with postlingual deafness achieved better results of rehabilitation in auditory perception than prelingually deaf patients. The linguistic improvement of grammatical and lexical aspect was noticed especially in prelingually deaf patients after implantation. This group of patients achieved also the significant progress in prosodic elements of speech in comparison with the results before implantation.
