RESUMO
UNLABELLED: THE AIM of this work was an evaluation of the rehabilitation results in a group of patients with a prelingual deafness DFNB1 type. MATERIAL AND METHOD: 50 patients examined, aged 12-15 years with non syndromic prelingual deafness. All patients were qualified on the basis on molecular and audiometrical examinations (the hearing threshold above 70 dB). In all cases audiologic, logopedic and lingual skill tests were performed. The control group were 50 school age children with environmental prelingual deafness. THE RESULTS of performed lingual test were following: 52% obtained low results, 16% middle results and 32% high results. In control group results were following: 42% low, 20% middle, 38% high level of speech efficiency. CONCLUSIONS: 1/3 of examined patients with nonsyndromic prelingual deafness independent on cause of hearing loss have possibility to obtain high speech efficiency.
