I. Case introduction

Primary four age:

Four-year-old dog: female

Sterilization or not: no

Chief complaint: swelling for about two days, ear scratching, and good appetite.

Sick dog Xiao Si

In the fourth grade, the auricle of the right ear stood up because of swelling, and the left ear shrugged.

Second, ear hematoma

1. Ear hematoma is a hematoma caused by the rupture of great blood vessels in the ear and the blood flowing between the ear cartilage and the skin.

Most of them occur on the inner surface of auricle, but also on the outer or both sides of auricle.

2. Reason:

Mechanical injuries, such as compression, contusion, scratches and bites of the ear shell, can all lead to ear hematoma.

Ear diseases, such as otitis externa, can cause ear itching, and animals can also damage blood vessels by shaking their heads and ears violently.

3. Symptoms:

Swelling: rapid formation, fluctuation, and painful reaction when touched. After bleeding and coagulation, fibrin precipitates and is distorted by palpation.

Blood or bloody liquid can be seen at the puncture site.

An abscess can be formed after hematoma infection.

Xiao Si's blocked ears.

During the examination, it was found that both ears of Grade Four had different degrees of suppuration and peculiar smell. The picture shows the left ear, showing that the external auditory canal is almost blocked.

Third, treatment.

1. Small hematoma can heal itself.

2. Cold compress combined with pressure bandage to stop bleeding on the first day of large hematoma.

3. Large hematoma should not be operated too early, because there is more bleeding after operation. Surgery was performed several days after the swelling formed, or after the swelling no longer increased significantly.

4. After the occurrence of ear hematoma, find out the cause and rule out the cause at the same time.

5. Cut, where the swelling is most obvious. Blood clots may appear a few days after hematocele and clot bleeding are ruled out. Therefore, after removing hematocele, hemostatic forceps should be used to remove blood clots.

6. Suture: two layers of cartilage are sutured at the same time; The wound site was not sutured and wound fluid was discharged. Take out stitches in 7~ 10 days.

Effect after suture

The effect of suturing is to cut the wound without suturing, which is beneficial to exclude blood.

Blood flowing out of the operation

On the operating table, after cutting the right ear of Xiao Si, blood flowed out.

7. Laser therapy Laser can penetrate different tissues in a gentle and controllable way.

Four. prevent

1. Prevent mechanical damage

When taking pets out for a walk, pay attention to the leash to prevent ear damage caused by fighting with other dogs. You should see a doctor immediately after the injury.

2. Prevention of parasitic infection

Due to ear diseases (such as otitis externa) caused by parasites (such as ear mites), pets will constantly scratch the affected ear, which may lead to the rupture of blood vessels in the affected ear, so it is necessary to check the ear health of pets regularly. Especially dogs with huge ears should pay more attention. Because the external auditory canal of big-ear dogs is covered by the external auditory canal, it is airtight and humid, which is easy to cause parasitic infection.

Step 3 prevent tick bites

The harm of ticks to pets is not only in the ears, but also may cause hind limb paralysis and some spleen-mediated diseases, such as babesiosis and Lyme disease. Anti-ticks should be carried out regularly, because ticks like to grow in the grass, so try to bring less pets out to play in the grass.

Five, about ear hematoma surgery

1. Precautions for operation will not be described.

2. Ear hematoma surgery, the cut wound is not sutured, but the blood vessels next to the incision are compressed. After the wound is cut and blood is drawn, the wound is not sutured to promote blood to flow out of the ear. Until the blood pressure in the ear is good and the wound fluid is finished. In the process of postoperative care, we should pay attention to whether the incision heals. After the wound is healed, the wound fluid cannot be discharged, and the ear will still swell.

3. Used for laser therapy

According to the equipment of each hospital and the conditions of doctors.
