Method of preauricular fistula resection

I believe everyone knows about the disease called preauricular fistula? It is an ear disease seen in outpatient clinics and is not easily visible to others. The common method to treat this disease is surgical resection. What is the specific method for surgical removal of preauricular fistula? What should I pay attention to? Let’s discuss it together.

Surgical method

1. The patient lies supine with the head tilted to the opposite side.

2. Infiltrate the area around the fistula with 1% procaine subcutaneously, insert a blunt-tipped curved needle into the fistula, and then inject 2% methylene blue solution to fill the branches of the fistula (Figure 1).

3. Make a fusiform incision around the fistula opening (Figure 2), cut the skin and subcutaneous tissue, and carefully separate along the blue-dyed duct (Figure 3), separate all the fistula branches, remove them cleanly (Figure 4), and then suture the subcutaneous tissue and skin (Figure 5). If the surgical cavity is deep, a small rubber drainage strip can be placed, covered with gauze, and pressure bandaged.

Points to note during surgery

1. After skin incision, prevent methylene blue from overflowing, contaminating surrounding tissues and affecting the search for fistulas. To this end, the fistula opening can be ligated or clamped; or the methylene blue solution injected into the fistula can be squeezed out before the skin incision is made and then the incision can be made.

2. Be careful when separating the fistula and do not tear or separate the fistula to prevent the contents of the fistula from overflowing and contaminating the wound and fistula residue, causing postoperative infection and recurrence.

3. When the fistula penetrates into the cartilage, the cartilage should be removed; after the fistula is removed, it should be examined and if there is any suspected epithelial tissue residue, it should be removed.

4. Do not damage the facial nerve.

5. For infected fistulas, acute inflammation must be controlled before surgery to avoid affecting healing.

Postoperative care

1. Use antibiotics to control and prevent infection.

2. If there is a drainage strip, remove it on the second day after surgery.

3. Skin sutures can be removed on the 5th day.

Commentary

Postoperative wound infection. If the auricular cartilage is affected, it may cause suppurative auricular perichondritis and lead to auricular deformity.

Through the introduction of the above article, I believe everyone has a general understanding of preauricular fistula resection? After the resection surgery, you must be more careful to avoid infection. If someone around us suffers from such a disease, we might as well recommend that they undergo tumor removal as early as possible to reduce the impact on their future life.
