Thank you for your question. First a disclaimer: I am not a plastic surgeon nor an opthalmologist, but I would try to answer your question based on my exposure to the topic during my trainee days.
From your question, it seems to me you had corrective surgery; I presume for your craniofacial condition? This commonly entails precise repositioning of the facial bones by creating breakages in the bone and then piecing them back together in the new position. Would this be the “fracture” you are referring to?
An actual orbital blow out fracture involves typically the floor and the inner wall of the orbit (eye socket) near the nose. Depending on the extent of the fracture, this may lead to loss of support for the globe (eyeball) which may result in the eye being in a wrong position. It may also lead to entrapment of the muscles which usually allow our eyes to move in all directions.
When this happens, the movement of the two eyeballs cannot be coordinated properly/ there may be a restriction in movement of the eye / double vision (usually on looking up and down). This may then lead to giddiness, nausea, and headache as the brain is not able to process the images from both eyes correctly.
I would recommend you consult a plastic surgeon, who would be able to assess if you have a sunken globe (enopthalmos) and whether you have limitation in your eye movement. Further investigations including a CT Scan of the facial skeleton may be required (sometimes with 3D reconstruction for precise surgical planning). Thereafter your plastic surgeon should be able to pick up any cause for the entrapment and may proceed to corrective surgery. If you previously had surgery done, this may involve removal of previous implants and placing new ones. If you suffered a fresh orbital blowout fracture, then the plastic surgeon may proceed to place a mesh (usually titanium or other inert material) to cover the defect so that the eye and its muscles can lie in the right position. Occasionally, the plastic surgeon may also involve an opthalmologist specialising in orbital fractures.
Hoping this helps!
