How are possible calcified cysts on the forehead diagnosed?

How are possible calcified cysts on forehead diagnosed? My swelling looks nothing like pictures of osteomas I have found – is this an interchangeable term for the same thing or not? If the symmetrical swelling all across my eye socket line on both sides does turn out to be this how is it treated / removed and which kind of specialist do I seek out in the first instance – ENT or a plastic surgeon for example?
