Why & When Do I Need Surgery For Preauricular Sinus or Cyst?

Preauricular pits are generally harmless and do not cause any significant health complications. However, sometimes they can become infected if bacteria gets trapped within the sinus, forming a cyst. Signs of an infection may include swelling, redness and discharge at the pit site.

Surgery to remove the preauricular sinus or cyst is recommended if there are frequent repeated infections and if the symptoms are causing great discomfort.


What Is Surgery For Preauricular Sinus or Cyst?

A preauricular sinus or cyst, also known as a preauricular pit, is a tract that travels under the skin that does not belong there. It is typically accompanied by a small hole located right in front of the ear and above the ear canal. If bacteria become trapped within the sinus, a cyst may develop under the skin.

A preauricular sinus is more common among children who may be born with it. Most cases of preauricular sinus or cyst develop only in one ear.

Possible Risks & Complications

While a preauricular sinus or cyst removal is usually a low-risk procedure, as with any other surgical procedure, there are always side effects observed.

The risks of any cyst removal can include:

  • Scarring
  • Infection at the incision site
  • Recurrence of the cyst
  • Improper healing of the incision site

    The risk may increase depending on your child’s condition, age and health.

What Happens During Surgery For Preauricular Sinus or Cyst?

You will be required to fast before the surgery. Generally, adult patients must abstain from food and water for 6 hours before surgery, while children patients must not eat or drink for 4 hours before surgery or as advised by the doctor.

During the surgery, your doctor will administer a general anaesthetic before making a small incision around the preauricular pit and removing the sinus tract.

Afterwards, the incision will be closed with stitches that dissolve on their own. When the procedure is complete, you or your child will be brought to a recovery room, where your vital signs will be observed as the anaesthetic slowly wears off.

What To Expect Afterwards?

Following the surgery, your doctor will likely advise you on some postoperative instructions on care and treatment during recovery. For example, they may prescribe antibiotics and over-the-counter medications to prevent infection and relieve discomfort.

Your doctor may also schedule follow-up appointments to check the incision site and track the healing process.
