MORPHOLOGICAL RESULTS WITH THE APPLICATION OF A XENOGRAFT IN EXPERIMENTAL TYMPANOPLASTY

Abstract

To date, there is no consensus on the question of which tissues are more appropriate to use for tympanic membrane plastic surgery. We decided to study the use of xenograft from sheep pericardium in tympanoplasty in rabbits in an experiment with chronic dry mesotympanitis. Experimental morphological studies using a xenograft were carried out in 28 rabbits. In the experiment, a positive result was obtained in 25 (89.3%), negative in 3 (10.7%) rabbits.
