Drenagem de otohematoma em cães

Abstract

Thirty-two dogs of different breeds of pendulum ears or not, male and female, were submitted to drainage of aural hematoma by removing circular fragments of 5 mm diameter skin. The ear cartilage was approximate to the skin with separate simple points and nylon 000. In the post-chirurgical period (PO) the dogs were kept with Elizabethan collar and ear bandage in a high position over the head for six days. After removal of the protective collar, the ears were kept upright anatomically built for 15 days, through a metal frame. Topic treatments were performed daily and removal of points was on the 10th day of PO. On 7th day of PO it was noted a slight uniform swelling, weep, crusts and thick skin; on 15th day a reducing of the skin thickness was observed and wounds were covered with connective tissue. Between the 30 and 60 days of the PO, circular areas were whitish in color with a slight contraction of the pinnal. The method facilitated the drainage of the hematoma with good adhesion between skin and cartilage and prevented the accumulation of exudates in the PO period. This method could be applied to correction of aural hematomas of dogs with pendulum and upright ears.
