Aural haematoma6/1/2023 Wounds of the pinna or earflap should be treated to prevent trauma to the ear caused by shaking and scratching. Allergies also can cause irritation to the ears. Ear swabs often are taken and the material is evaluated under the microscope to look for causes of otitis such as yeast, ear mites, or bacteria. The veterinarian may use an otoscope to look down into the ear canals to determine the presence of a foreign body or inflammation in the ears. A thorough examination of the ears will be necessary. To help prevent aural hematoma formation, it is essential that the veterinarian determine what is causing the irritation that is making the animal shake its head or scratch its ears. Also, scar tissue formation within the hematoma will result in a severely wrinkled, thickened earflap that will predispose the pet to further ear problems. Approximately seven to 10 days following the procedure, after the ear has drained and healed fully, the sutures will be removed.įailure to treat a hematoma can lead to enlargement of the swelling to encompass the entire earflap. Then, multiple sutures will be stitched into the ear to seal it back together. The ear eventually seals back together as the owner milks the fluid from the hematoma through the cannula each day.Īnother method, performed under general anesthesia, involves making a surgical incision into the swelling on the ear, allowing the fluid to drain. One method for correction which requires that the animal be sedated lightly is placing a drain, called a teat cannula, securely into the tip of the ear and allowing the ear to drain from the cannula for a period of three weeks. There are several procedures for treating aural hematomas the veterinarian's approach to the problem will depend on the severity of the pet's condition. However, unless the underlying cause of the irritation to the ears is controlled, it is possible that another hematoma will develop at a later time. The prognosis is excellent for the correction of the hematoma. Allergies, an infection or inflammation of the ear, the presence of a foreign body, or ear parasites all cause pain, itchiness or irritation that an animal would seek to alleviate by head shaking or scratching. This behavior causes the tiny blood vessels of the ear to rupture and hemorrhage under the skin forming a pocket of blood within the earflap. The cause is due most commonly to self-inflicted trauma such as scratching and shaking of the head. Many dogs with this condition have a history of ear problems or infections. The swelling can sometimes be at the base of the ear. The flap of the ear will have a firm swelling on its inside that may be red and warm to the touch. The examining veterinarian will be able to treat this hematoma by any of several procedures that drain the fluid. When the tiny blood vessels in the ear's cartilage rupture and bleed, the hematoma, a firm, fluid-filled swelling, will appear within the animal's ear. This behavior can cause trauma to the animal's pinna, or earflap, that can add even more irritation to the ear.Īn aural, or ear, hematoma is a swelling in the earflap resulting from an injury. When an animal has a painful or itchy ear, it may swing its head about or scratch its ear to alleviate the discomfort.
