What is a dermoid cyst?
A ‘congenital’ cyst (meaning born with it) lined on the inside with skin cells.
The cyst is usually not apparent at birth, but is discovered later as is slowly grows.
Why does the cyst occur near the eye?
While dermoid cysts may occur in a variety of locations, near the outer end of the eyebrow is a common site. When an embryo (unborn baby) develops there are 2 folds which join in this region. A few skin cells may become trapped under the skin at this join, and grow into a cyst.
What problems can a dermoid cyst cause?
- Infection
- Cosmetically unattractive
What is the treatment?
Surgical removal.
How is this done?
Under a general anaesthetic (asleep) in the operating room.
The location for the surgical incision depends on the exact location of the cyst but may be just above or below the eyebrow or in an upper eyelid skin crease.
What are some of the possible complications?
- Infection in the wound
- Bleeding
- Recurrence
What to expect after the operation
Your child will stay in hospital for approximately 2 hours following surgery and go home after this, when fully recovered.
There will be a scar at the site where the cyst had been.
The stitches are dissolvable and usually cannot be seen because they run under the skin (‘subcuticular’).
Some bruising or mild swelling soon after the operation is to be expected.
Your surgeon or anaesthetist will usually use local anaesthetic to reduce pain after the operation. This wears off after a few hours. At home, give paracetamol for pain relief.
