This refers to
pocketing or ballooning of the pinna, with blood from damaged blood vessels in the ear. Aural haematoma can be caused by direct damage to vessels in the ear.
The damage could be as a result of bite wound,accidents,but the most common cause is severe head shaking and scratching which is associated with heavy tick infestation.
Otitis media and allergic dermatitis are underlying causes of
aural haematoma,hence thorough examination is essential in treatment protocol.
Treatment of haematoma can be surgical or non surgical intervention.
Haematomas can resolve on their own but the ear will assume a cauliflower shape,hence disfiguring the shape and size of ear.
Non surgical intervention involves draining the fluid and flushing the cavity with saline to remove any clot or fibrin. The draining will be done a number of times because the haematoma recurs.There is a tendency for secondary bacteria infection because of several needle pokes,hence complicating the case of haematoma.
The surgical intervention involves lancing the haematoma,flushing the cavity with saline,then some sutures are placed on the pinna.
The sutures are to hold the wall to the cartilage beneath,to ensure there is no space for pooling of blood.The incision site is not sutured,rather the sutures placed on both sides of pinna provide the necessary closure.
The sutures are removed after a week, and the animal is placed on antilnflammtory drugs,analgesic and incision site is sprayed with wound oil treatment to repel flies.
The ear could be wrapped up in bandage or a head collar is placed on the animal to prevent cutting off the stitches.

Samuel Lin from Harvard Medical School and David Kaplan at Tufts University in Medford, Massachusetts have invented silk screws for bone repair. They made several researches over silk and molded the material into screw shapes. The silk screws are stronger than it seems and they can fix fractures and bone problems.
When the silk is stretched it becomes as strong as steel ,this property makes the screws cut through bones. They are the best alternative to all previous suturing methods. The metal can corrode, and they need a second intervention. The other biodegradable alternatives can cause severe inflammation while the polymers are too soft and need drilling the bone.(coolweird.com)
The silk screws are the only bone screws that are strong enough, naturally biodegradable and while they biodegrade don’t cause inflammation. Ideally, they could be used in place of metal plates and fasteners in many circumstances. That would mean no more setting off detectors or experiencing pain when cold temperatures set in. This could also be of great benefit to overall healing, as using metal in the body has been observed to slow wound healing and assist the rapid development of infection. In cases where permanence isn't needed, silk is being touted as an ideal alternative to traditional materials especially since, over time, it dissolves in the body.
