Infraorbital Foramen

The infraorbital foramen is the opening in the skull that connects the nasal cavity to the facial part of the skull. It is located between the lower jaw and the front of the eye socket. Vessels, nerves and muscles pass through this hole, which provide movement of the eyeballs and face.

The infraorbital foramen has an oval shape and is located at the level of the lower edge of the orbit. It is bounded externally by the upper jaw, internally by the orbital septum, and inferiorly by the lower jaw.

The following structures pass through the infraorbital foramen:

– infraorbital nerve – it provides sensitivity to the skin and mucous membranes on the front of the cheek, as well as innervation of the teeth of the upper jaw;
– maxillary canal – the infraorbital artery passes through it, which supplies blood to the upper jaw and anterior teeth;
– infraorbital muscles – they are responsible for the movement of the eye muscles, raising the upper lip and lowering the lower.

Also, some other structures may pass through the infraorbital foramen, such as the infraorbital canal, which connects the nasal cavity to the middle cranial fossa.

Violation of the integrity of the infraorbital foramen can lead to various diseases and complications, such as infection, bleeding, impaired sensitivity and movement of the face, as well as facial deformation and dental problems. Therefore, it is important to monitor the condition of this hole and consult a doctor if necessary.

The infraorbital type of foramen is one of the most common. It is located between the eye sockets and the lower jaw, which provides easy access to the upper teeth. This hole has a width of 4 mm to 6 mm and is located on the border of the zygomatic arch and jaw. It is located on the upper border of the jaw branch at approximately a distance of 30-35 mm from the molar and at a height of approximately 25-3
