title: [Comparative evaluation of mastoidoplasty results in application of various plastic materials].
abstract: The results of surgical treatment of 62 patients, suffering chronic purulent middle otitis, were analyzed. The structure of mastoid processus and attic constitutes a base for choice of middle ear surgical sanation. Sanation operation with preservation or reconstruction of external acoustical meatus posterior wall was finished with combined mastoidoplasty using autobone, spongioid bone bioimplant Tutoplast or bioceramic material "Sintekost". Achievement of a steady sanating effect have promoted in late postoperative period a trustworthy lowering of the perception threshold of the bone--conducted sounds as on vocal, and also on high frequencies, while of the air--conducted sounds--on vocal frequencies. This permits in perspective to perform a hearing--improving operations with good functional result.
