[Results of rehabilitation of patients after cochlear implantation of a single-channel extracochlear neuroprosthesis manufactured in Czechoslovakia].

The authors present an account of the results of rehabilitation of the first three subjects after cochlear implantation of a Czechoslovak single-channel neuroprosthesis. The results of rehabilitation were evaluated by means of specially designed videotests and audiotests to make the results comparable with results of neuroprostheses implanted abroad. Based on these tests--in particular MSD--they reached the unequivocal conclusion that the results of cochlear implantation of the Czechoslovak extracochlear neuroprosthesis, as far as rehabilitation is concerned, compare favourably with results achieved by other neuroprosthesis of this type. In all three patients the neuroprosthesis mediates to the patients information on the presence of sound, in many instances it makes identification of this sound possible. In combination with lip-reading the patients are able without major problems to communicate with the environment. Resocialization of the operated patients was achieved.
