Supraorbital foramen

Supraorbital foramen is a significant anatomical feature located in the human skull. It is a bony opening that is found in the frontal bone, above the eye socket or orbit. The term "supraorbital" is derived from the Latin words "supra" meaning above and "orbital" referring to the orbit or eye socket. The "foramen" is a Latin term for hole or opening.

Anatomy

The supraorbital foramen is a small hole located on the frontal bone, which forms the forehead and the upper part of the eye sockets. It is positioned above the midpoint of the eyebrow. In some individuals, instead of a foramen, there is a supraorbital notch. The size and shape of the supraorbital foramen or notch can vary among individuals.

Function

The main function of the supraorbital foramen is to allow the passage of the supraorbital nerve, a branch of the trigeminal nerve, and the supraorbital artery and vein. These structures provide sensation to the forehead and scalp and supply blood to these areas.

Clinical significance

The supraorbital foramen is an important landmark in several surgical procedures involving the orbit or forehead. It is also significant in forensic medicine for the identification of human remains. In addition, the supraorbital nerve that passes through the foramen can sometimes be affected in conditions such as trigeminal neuralgia or migraine.
