What’s this hard lump on the edge of the orbital bone?

Hard lumps felt on the margins of the orbital bones are usually caused by nodules or dermatomal cysts on the orbital bone margins.
The edge of the orbital bone wall is not completely smooth, because of the existence of individual differences, some patients will have nodule formation, which is a physiological phenomenon and does not require treatment.
Orbital dermatoid cysts are caused by congenital developmental abnormalities, usually grow in the orbital bone seam area, will form nodules, and may continue to grow, usually need to be surgically removed to be able to cure.
Patients who feel a lump forming on the edge of the orbital bone should go to the ophthalmology department of the hospital in a timely manner, and the doctor will clarify the specific cause by doing orbital CT examination, etc., and then formulate an individualized treatment plan.
