1. What are orbital cysts? When we talk about orbital cysts here, we are referring specifically to dermatomal cysts and epidermoid cysts. 2. What are the manifestations of orbital cysts? Some cysts grow shallowly, just under the skin, and when you are a child, you may find a round bag around your eyes or eyebrows that can be pushed by hand and still move. The deeper cysts grow between the muscle and bone, and because they are deep, they look flat and cannot be pushed. The deeper ones are located behind the eyeball, and the child will come to the hospital because of the protruding or displaced eyeball only when the eyeball is pushed forward by the growing cyst when the child grows to be a teenager or older. Sudden redness, swelling, and “pus” The cyst suddenly breaks down and discharges toothpaste-like material, which can become red and painful secondary to infection. Orbital cysts are born because some cells are misplaced during the baby’s embryonic life. Therefore, the cysts exist at birth and are not detected at first because they are small, but gradually reveal themselves as they grow up. 4.What tests should be done to clarify orbital cysts? B-ultrasound: can see if the lesion is cystic or not CT: can see the location of the lesion, the relationship with the bone, and the pressure on the bone MRI: can help determine the composition of the cyst 5.How is an orbital cyst treated? Surgery. The cyst will not disappear on its own, but will only grow bigger and bigger steadfastly …… The bigger the cyst grows, the more it will affect the function and appearance of the eye, and the longer the incision will need to be by then, so it is better to operate earlier. 6.What is the key to surgery? The key to surgery is to remove the cyst completely and remove the cyst wall cleanly to avoid recurrence. Many cysts grow out of the bone, including the bone crest and tunnel, and have to be removed. Other cysts are very deep and grow behind the eye, requiring a lateral orbital opening. All these need to be done by professional eye tumor orbit surgeons. 7. What should I do if I want to operate but I am afraid of scarring? The appearance of the child is also our main concern. Through intracutaneous cosmetic sutures (no stitches on the outside of the skin), combined with postoperative scar management (scar removal medications, tension reducers, tension reduction tape, etc.), multiple aspects work to make the scar inconspicuous. 8.Is orbital cyst surgery under general or local anesthesia? Children can not cooperate with local anesthesia, or general anesthesia is safe and reliable. The surgery will be done after a good night’s sleep! (Dr. Song himself has also been under general anesthesia, so don’t worry. Large and small, deep and shallow, white and yellow, some like cheese, some like toothpaste, some a packet of oil, some a packet of water.
