Most of the commoner disorders in the supra-orbital region arise from the eye or the frontal sinus and are handled by the specialists in these branches, so they will not be considered here. But there are many injuries and new growths that require in their treatment an intimate knowledge of the unusual anatomic features in this vicinity. Here we have, in close proximity, an important organ of special sense, the eye; a cavity lined by mucous membrane, the frontal sinus, and the brain, enclosed in its bony walls covered with modified skin and fascia.
The foundation on which the tissues rest is the frontal bone. The supra-orbital margin forms the tipper boundary of the orbit, and above it is the superciliary ridge, a dense bony structure protecting both the eye and the brain.
