Supraorbital Foramen, Supraorbital Notch [Foramen (Sive Incislira) Supraorbitale, Pna; Foramen Supraorbitale, Bna; Incisura Frontalis Lateralis, Jna]

The supraorbital margin is one of the most important parts of the skull, which is located on the inside of the forehead. It consists of two parts - medial and lateral. The medial part, which is closer to the bridge of the nose, is called the supraorbital notch, and the lateral part, located closer to the temple, is called the supraorbital foramen.

The supraorbital foramen is a small opening in the medial part of the supraorbital margin, which is located on the inner side of the frontal bone. It has an oval shape and is located at the level of the eyeball. The supraorbital foramen contains important structures such as the supraorbital artery, vein, and nerve, which provide blood supply and innervation to the frontal region.

In addition, the supraorbital foramen plays an important role in the formation of the frontal sinus, a cavity that is located between the frontal bone and the skull. The frontal sinus is one of the main organs of the respiratory system and provides cooling to the brain during heat.

Thus, the supraorbital foramen is an important anatomical formation that provides blood supply and innervation to the frontal area of ​​the head, and also participates in the formation of the frontal sinus.



The supraorbital foramen, also known as the supraorbital notch (foramen (sive incislira) supraorbitale, PNA; foramen supraorbitale, BNA; incisura frontalis lateralis, JNA), is an opening or notch in the medial half of the supraorbital margin of the squama of the frontal bone. This anatomical feature plays an important role in the passage of blood vessels and nerves, providing communication between the front of the skull and the orbital area.

The supraorbital foramen is the structure through which the supraorbital arteries, veins, and nerves pass. The supraorbital arteries are branches of the internal carotid artery and provide blood supply to the forehead and orbit. The supraorbital veins drain blood from the corresponding areas and drain into the facial and maxillary veins. Nerves passing through the supraorbital foramen include the supraorbital nerve (nerve V1), which is an important component of the trigeminal nerve and supplies the skin of the forehead, upper eyelid, and supraorbital arch region.

The anatomical location of the supraorbital foramen is determined by its functional needs. It is located in the medial part of the supraorbital edge of the squama of the frontal bone, which allows it to effectively provide blood supply and innervation to the corresponding areas of the face and eye. In addition, the location of the opening is also important when performing surgical procedures such as endoscopic orbital surgery or supraorbital blocks.

In conclusion, the supraorbital foramen, or supraorbital notch, is an important anatomical structure that provides passage of blood vessels and nerves between the front of the skull and the orbit. Its understanding and consideration during surgical interventions are important aspects for achieving successful results and minimizing risks for patients.
