Background

An auricular hematoma is also termed as “cauliflower ear” is an injury that is marked by enlarged ears and stagnant accumulation of blood beneath the cartilage and skin of the ear. This frequently follows injuries, like blunt force, or friction which can further tear blood vessels of the ear tissues. Without being treated auricular hematoma may lead to deformation of the ear and other complications like infection and dying.

Indications

Tender anterior auricular swelling after trauma: This will induce a remarkable swelling and deformation of the normal anatomy of the pinna (the outer ear).

Pain and Tenderness: The patient may feel some pain or local ache when touching or manipulating the affected ear.

Contraindications

Hematoma that are older than 7 days: Once the absence of blood continues for a longer period, blood starts to clot, and extraction becomes even more complicated.

Unrepaired laceration, particularly with exposed cartilage: If the cartilage remains visible under the broken skin, the doctor should perform remedial work on the laceration first.

Outcomes

Equipment

  • Sutures
  • Compression dressings
  • Sterile gauze pads
  • Antiseptic solution
  • Suction device
  • Aspiration syringe
  • Anesthesia

Patient preparation

The doctor shall explain to the patient and the patient will sign the consent form which the surgeon will handover to.
In order to establish the size and site of the hematoma, usually, the physician carry out the physical ear examination.

Physical ear examination

The surgeon can either choose needle aspiration or surgical drainage based on the size of the hematoma.

Patient position

The patient position is lateral decubitus.

Technical considerations

Step 1: Patient Positioning and anesthesia: A patient will be lying down with a head that is elevated above and his or her affected ear upwards facing.

Step 2: Drainage Procedure:
Incision: Through a small hole between the natural folds of the cartilage, that leaving behind a scaring is targeted.

Hematoma Removal: To access the hematoma, the surgeon will cautiously detach the skin and underlying tissue from the cartilage.

Irrigation and Cleaning: The area surrounding the hematoma is washed out with sterile saline solution to remove any specific blood or debris.
Step 3: Closure and Dressing:

Dressing for auricular hematoma with bandage

Antibiotic Ointment: The incision will be covered with a thin layer of antibiotic ointment.

Compression Dressing: A pressure bandage will be applied to the ear to prevent blood reaccumulation and aid healing, possibly consisting of gauze pads and dental rolls.

Laboratory tests

Auricular hematoma drainage does not necessitate any laboratory testing.

Complications

Infection: This is the most common complication of any procedure with a skin puncture.

Recurrence of hematoma: There is a possibility of a recurrence of the clot symptoms after the blood clot is drained. This is more likely to become true if the person does not follow the surgeon’s instructions about caring for the treatment after the patient is discharged from the hospital, including wearing a pressure dressing.

Cauliflower ear: It is an abnormality in the cartilage of the ear that results if the cartilage formed is not firmly fixed on the blood clot after draining. Several patients who have sustained multiple hemorrhages around their ears are at a higher risk.
