Composite Acellular Collagen Glue: A Novel Treatment Method for Aural Hematomas in Dogs

Background: An aural (auricular) haematoma is a collection of blood within the cartilage plate of the ear and occurs mostly in dogs. This study aimed to assess the healing and cosmetic effectiveness of collagen glue in treating aural hematomas in dogs. Methods: Eighteen clinical cases of dogs suffering from haematoma were divided into three groups. In group I (n=6), horizontal mattress sutures were applied, in group II (n=6), horizontal mattress sutures along with collagen glue was applied and in group III (n=6), sole application of collagen glue was done for the obliteration of dead space. Various parameters such as thickness of pinna, degree of exudation and inflammation, cosmetic appearance, healing time, surgery time and recurrence were recorded. Result: Post-operative evaluation revealed that the thickness of ear pinna was reduced mostly in group III (5.43 ± 0.46 mm) along with reduced exudation and inflammation by day 14 and 21 respectively.
