The Auralsplint is the only corrective treatment for aural hematoma in canine. The treatment kit is complimentary with inclusion in the Free Case Trials ongoing (see Contact and About). The aspiration by hypodermic needle is most important before 7 days since onset of the hematoma. ! Have your veterinarian aspirate the hematoma. Do not leave the clinic without an aspiration by hypodermic needle. Any length of time beyond 6 days poses the threat of not being able to use the auralsplint.
