Aural hematoma in pigs occurs due to bacterial infections, often caused by Actinobacillus suis, that lead to vasculitis and hemorrhage in the delicate blood vessels within the ear. The condition presents as fluid-filled swellings within the ear, causing distortion and pain. Diagnosis involves clinical examination and fluid aspiration. Treatment usually involves surgical drainage and antibiotic therapy. If left untreated, the hematoma can lead to complications such as ear necrosis and deafness. Prevention focuses on controlling infections through vaccination and hygiene.
