The animals were divided into two groups viz., Group I and Group II, each consisting of six animals. In Group I, surgical drainage was carried out and the dead space was obliterated by applying a series of through and through (full thickness) interrupted mattness suture. In Group Il, surgical drainage was carried out and the dead space was obliterated by applying a series of partial thickness interrupted mattress suture. In Group I, the dogs were aged three to eight years and the duration of illness varied from three to fourteen days. Shaking of the head, scratching and drooping of the affected pinna were observed in all the dogs, except scratching in one dog. Length of the ear and haematoma varied from 7.4 cm to 13.7 cm and 7 cm to 12 cm respectively. Width of ear and haematoma varied from 4.7 cm to 9.2 cm and 3.6 cm to 7.4 cm respectively. Thickness of haematoma varied from 2.1 cm to 5.5 cm. The physiological parameters like rectal temperature, pulse rate and respiratory rate was found to be within normal range. The haematological values such as, packed cell volume, total erythrocyte count, haemoglobin concentration, total leucocyte count and differential leucocyte count were also within normal physiological range. Post-operatively self mutilation of wound, scratching and shaking of the head were reported in a few animals and carriage of affected ear was drooped in all the animals. There was no accumulation of blood or exudates in any of the animals. Most of the animals retained bandage. Photographs of the affected ear was taken before surgery, immediately after operation and thereafter on third, sixth, ninth and thirtieth day and were observed for evaluating the post-operative cosmetic appearance of the pmna. Puckering of the affected pinna was noticed in four dogs by the ninth day and it was marked in all the dogs by one month. In Group II, the dogs were aged three to six years and the duration of illness varied from two to 14 days. Shaking of the head, scratching and drooping of pinna were observed in all the dogs. Length of the ear and haematoma varied from 6.8 cm to 12.3 cm and 5.9 cm to 11.2 cm respectively. Width of ear and haematoma varied from 4.5 cm to 7.3 cm and 2.9 cm to 6.5 cm respectively. Thickness of haematoma varied from 1.2 cm to 2.9 cm. The physiological parameters like rectal temperature, pulse rate and respiratory rate was found to be within the normal range. The haematological values such as packed cell volume, total erythrocyte count, haemoglobin concentration, total leucocyte count and differential leucocyte count were also within the normal physiological range. Post-operatively shaking of the head, scratching and self mutilation of wound were reported in a few animals and carriage of affected ear was drooped in all the animals. There was no accumulation of blood or exudates in any of the animals. Most of the animals did not retain bandage. Photographs of the affected ear was taken before surgery, immediately after operation and thereafter on third, sixth, ninth and thirtieth day and were observed for evaluating the post-operative cosmetic appearance of the pinna. After one month of examination of the ear, which was affected with haematoma, revealed perfect healing without any puckering or distortion of pinna. Histopathological examination of the collected specimen from the affected ears revealed irregular separation of the perichondrium, necrosis of the perichondrial connective tissue, diffuse inflammatory cell infiltration in the damaged perichondrial zone along with subchondral accumulation of blood cells. The cartilage appeared distorted and showed loss of chondrocytes at certain areas.
