Využití autologního materiálu ve středoušní chirurgii
Use of Autologous Material in Middle Ear Surgery The use of autologous material in kofosurgery has been preferred to that of homologous or aloplastic materials in most situations. However, the use of autologous material in patients with cholesteatoma has been limited by the risk of harbouring residu...
