Analysis of clinical data in cochlear implantation
Staňková, Helena ; Kolářová, Jana (referee) ; Odstrčilík, Jan (advisor)
Cochlear implants compensate various audiological disorders in postlingually and prelingually deaf patients. Clinical examinations including radiological, anatomical and audiological measurments provide crucial informations leading to cochlear implantation and optimal postoperative rehabilitation. In cooperation with ORL clinic at St. Anne’s University Hospital this work deals with analysis of clinical data provided by cochlear implant users. Data analysis includes otological planning with OTOPLAN software, use of MAESTRO software, TomoCon software and hospital information system. Data were statistically processed using MATLAB programming language. Work results based on diverse data bring an united view, which could serve as helpful indicator in preimplantation and post-operative care in newly implanted patients.

Signal processing used in hearing devices
Kelča, Jan ; Harabiš, Vratislav (referee) ; Kolářová, Jana (advisor)
In this work is in details described anatomy and physiology of auditory tract, all its pathological changes included. The main part of this work concetrates on the issue of hearing disorders compensation when special emphasis comes to cochlear implants. This work characterizes every single functional part of cochlear implants from microphones to electrode array. The thesis works in details with speech processors of cochlear implants and with possibilities that provides codes strategies. In a practical part of this thesis is designed the scetch of block scheme of the cochlear implant using CIS and ACE strategy. As an outcome has been made the programme for processing acoustic signal that is based on mentioned block scheme.

Speech therapy for children after cochlear implantation in the preschool age. Evaluation of passive vocabulary and understanding of speech by children with cochlear implants before starting school
Salačová, Martina ; Hádková, Kateřina (advisor) ; Mrkosová, Eva (referee)
Thesis deals with issues of cochlear implants. It is focused on pre-school children one year before attending basic school. Thesis discusses all requisites that precede, accompany and follow cochlear implantation. We primarily determined the possibilities of children with cochlear implants, whether they can reach approximate levels of communication as intact children of the same age specifically in development of passive vocabulary and in the ability of understanding of speech. We choose the test Diagnosis of Language Development (Diagnostika jazykového vývoje) by Gabriela Seidlová Málková and Filip Smolík. The results of tests of children with cochlear implants were compared with tests of intact children of the same age. Next we used analysis of expert literature and interviews with teachers to determine which particular factors have underlying influence in the process of therapy of children after cochlear implantation and which influence them enough so children with cochlear implants approach communication levels of intact children. These factors were tracked in case studies of two girls with cochlear implants. KEYWORDS: cochlear implants, passive vocabulary, understanding of speech, preschool age, speech therapy
