The ‘Aural Splint’ – Veterinary Treatment for Aural Hematoma
The ‘Aural Splint’ is a veterinary alternative holistic corrective non-surgical treatment for auricular hematomas occurring in animal ears.
The ‘Aural Splint’ treatment is patented for features which correct the causes and effects of the hematoma.
The ‘Aural Splint’ is being introduced to the veterinary industry for the expressed use in animals with age and health issues preventing the use of general anesthesia, necessary for to undergo the surgical repair of the hematoma cavity. It can and should be used for all aural hematomas in pendant and erect ears in dogs, cats and other animals.
The ‘Aural Splint’ uses the animal’s healing defenses to correct the hematoma and inhibit the deformation of the ear.
Brief description of the aural hematoma affliction:
A blood vessel ruptures within the ear flap (pinna) and causes a pool to form. The pool grows by expanding toward the ears edge tearing apart the layers of the skin and cartilage. The pool can continue to grow till it completely fills the pinna. The cause of the hematoma may be from ear flapping by the animal due to aggravation from insects or infection, or possibly a genetic prevalence.
The outcome of an aural hematoma left without treatment generally deforms the ear by shriveling and hardening of the pinna. This situation is not conducive to a healthy ear canal because of the obstructing pinna. The appearance will be a noticeable disfigured ear and not like the other. In worse cases, the ear flap will rupture and infection will set in completely disfiguring the ear and potentially harming the animal’s health.
Options for treatment of aural hematoma in pendant eared dogs:
Take the animal to your veterinarian for a visual and medical checkup to try to diagnose why the hematoma is occurring. Microscopic and blood testing is performed to determine if infestation or infection is present. The overall health of the animal is determined.
Option one: Surgery depends if the animal is too old or otherwise not of good health to undergo general anesthesia required to undergo surgery to relieve and repair the ear pinna. If this case exists, then the surgery is not an option.
Outcome one: Generally accepted as best option to repair the pinna. However, the surgical option is very invasive leaving the animal with a lengthy and painful recovery during which the animal will need constant care to apply topical medications to large wounds, cleaning of the wounds, and oral medications to relieve pain and prevent internal infections. The surgery leaves open wounds to allow the broken vessel to continue to bleed and the owner to tend to.
Option two: The other option is to relieve the blood pool by aspiration with a hypodermic needle. Medical injections of the veterinarian’s determination may be performed as an inhibitor to swelling or pain.
Outcome two: The hematoma will continue to refill the pinna till at some time the vessel seals and the cavity where the hematoma occurred forms a large blood clot and hardens. Depending on how large the blood clot is and how long the animal has had the hematoma, the results are discomfort during healing and disfigurement after. The potential for infection during the frequent aspirations is a concern. The possible obstruction of the ear canal after the ear shrivels is also a concern.
Either of the two options, available at present by the veterinarians, do not address the root problem of the aural hematoma: the broken blood vessel is still broken. Unless this problem is addressed, then healing cannot occur. The surgery splays open the ear to remove the fluid build-up and clotted blood present. Mattress sutures are applied throughout the pinna to locate the skin next to the cartilage to promote adhesion, but the sutures penetrate through the entire pinna leaving the opportunity for infection at any of the suture sites. A similar surgery with a biopsy punch make holes instead of an incision and uses a co2 laser to create an array of spot attachments (more wounds) on the entire underside of the pinna where the hematoma has occurred. Still, the biopsy holes are for the removal of the fluids and the relief of any more fluids building into the affected area of pinna. Sometimes the veterinarian will install a tube allowing the blood returning into the hematoma to flow out of the cavity and away.
The ‘Aural Splint’ is now the only option addressing the expressed correction of the broken blood vessel.
The ‘Aural Splint’ treatment consists of two flat or conical shaped plates conforming to ear size and containing a raised rib at or around the base of each plate, when situated and held in place against the pinna, act as a splint by holding the pinna in a defined location not allowing the hematoma to fill uncontrolled. Using non-elastic tape to hold the plates in place, the plates offer the pinna a protective environment to slightly refill and then have the broken blood vessel be stopped by the back pressure of the confined space between the plates. The raised rib provides a stop mechanism not allowing the hematoma to extend beyond the predetermined area of treatment. By having the small amount of blood in the hematoma cavity and the skin and cartilage in close proximity to each other, the characteristic of the blood will coagulate the broken blood vessel as well as act as an adhesive agent to bond the skin to the cartilage.
With the pinna protected and no chance of infection from additional wounds, the ‘Aural Splint’ allows the animals own healing bodily fluids to work toward a far successful outcome than the surgical or medical options presented until today.
