Prevention
To help prevent aural hematoma formation, it is essential that the veterinarian determine what is causing the irritation that is making the dog shake its head or scratch its ears. A thorough examination of the ears will be necessary. 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. 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. Allergies also can cause irritation to the ears. Wounds of the pinna or earflap should be treated to prevent trauma to the ear caused by shaking and scratching.
