Abstract
The objective of this study is to evaluate the possibility of using collagen membrane in otosurgery. The results proved that a bilaminar collagen membrane has sufficient sizes to completely cover plastic material in mastoid obliteration. The material has a long period of resorption, thus providing complete regeneration of the reconstructed external auditory passage epidermis. As a resorbable membrane for guided bone regeneration, collagen membrane improves osseointegration of plastic material in mastoid obliteration. 16 patients with the so-called «operated ear disease» had been operated on, autologous bone chips were used as a plastic material. Plastic material was covered with collagen membrane. 6 months after the surgery, the plastic material of all patients was covered with the skin of external auditory passage.
