Applied plate is larger in size than size of tympanic membrane perforation and obligatorily reaches anterior wall of tympanic cavity. In addition, support autocarilagineus plate is installed under anterior edge of neotympanic membrane, being pressed to anterior and internal walls of tympanic cavity, from lower wall downward to the area of auditory tube orifice at the top.
