Anotation. The article presents data on the clinical study of dogs with hanging ears of different breeds and age groups, which were adopted with a hematoma of the ear, with the diagnosis of an otogematoma, which emerged as a complication for untimely diagnosed otitis in dogs and for untimely treatment of patients. The most common causes were ailments of different etiology (60 %), mechanical traumas of the ear (35 %), autoimmune diseases, weakness of blood vessels (5 %). Surgical care was provided 2-3 days after the injury. Treatment was carried out with the help of a special compressor BUSTER. All animals were divided into 3 groups: 1 control and 2 experimental. In the control group, no surgical treatment was performed, only puncture of the otogematoma and removal of the contents with the help of a sterile syringe with the imposition of a pressure bandage - as a result of which healing did not take place, and after 20 days thickening of cartilage was observed. I experimental group: 10 dogs - surgical treatment of otogematoma was performed with the help of compressor «BUSTER» with execution of «S» of similar section and imposition of firmware «P» of such ligature. After 20 days, complete wound healing was observed without cartilage thickening. II experimental group: 10 dogs - surgical treatment of otogematoma with the help of the usual direct incision and the imposition of stitching seams from bandage rollers. After 30 days, wound healing and cartilage thickening were observed. Thus, the use of a special compress allows you to completely abandon the use of improvised materials and restore the structure of the ear for 15-20 days.
