It is recommended that you seek veterinary attention for ear hematomas as soon as possible. Small hematomas often grow in size, and the larger the hematoma, the longer it will take to heal. Treating the condition quickly will result in a better chance for full recovery.
The pain caused by an ear hematoma will likely subside in a few days. If left untreated the ear will eventually reabsorb the fluid, and the condition will resolve itself. However, this is not recommended. The affected area will continue to be swollen and scar tissue will develop, leaving behind an unsightly condition that is referred to as “cauliflower ear.”
There are several treatment options available. Your veterinarian will decide which is right depending on the size of the hematoma, the length of time the ear has been affected, and his or her personal preference.
Surgery with Sutures
Surgery with sutures is the most common treatment for ear hematoma in cats. The cat is placed under anesthesia and a small cut is made to the underside of the ear. The fluid is allowed to drain out and multiple sutures are placed in the affected area. This not only treats the hematoma but also helps to prevent reoccurrence. The ear may or may not be bandaged after surgery. Stitches are removed in 2-3 weeks and as long as the underlying condition has been properly treated the animal has a good chance at full recovery.
Surgery Without Sutures
This method is very similar to the one above, with the exception of the use of sutures. After the ear has drained it is taped over a rolled bandage and left to heal. Owners will be required to be more vigilant with aftercare due to the fact that the wound has not been closed. This option is commonly used on show cats as there is less of a chance of ear deformity following treatment.
Non-Surgical Treatment
Your veterinarian may choose this option if the hematoma is very small. A needle is inserted into the affected area to remove the fluid and a drainage tube may be inserted. This method is less effective and leaves a greater chance that the hematoma will reoccur. It is usually only recommended for animals that can’t tolerate general anesthesia.
