Otoscopy at epitimpanit In the ear canal pus greenish-yellow, thick, with a putrid odor, sometimes mixed with holesteatomnyh masses. Perforation is located in the slack of the membrane, and it reaches the edge of the bone edge of the frame - regional perforation. It may be destruction of the bone wall of the upper division of the tympanum - epitympanum
