Infraorbital margin[edit]
The infraorbital margin is a prominent anatomical feature of the human skull. It forms the lower boundary of the orbit, which is the bony cavity that contains the eye and its associated structures. The infraorbital margin is an important landmark in both clinical and surgical anatomy.
Anatomy[edit]
The infraorbital margin is composed of two bones: the maxilla and the zygomatic bone. The maxilla forms the medial part of the margin, while the zygomatic bone forms the lateral part. These bones meet at the zygomaticomaxillary suture, which is located near the midpoint of the infraorbital margin.
Maxilla[edit]
The maxilla is the upper jawbone and plays a crucial role in forming the roof of the mouth, the floor of the nose, and the floor of the orbit. The infraorbital margin is part of the maxillary bone's contribution to the orbit.
Zygomatic bone[edit]
The zygomatic bone, also known as the cheekbone, contributes to the lateral wall and floor of the orbit. It articulates with the maxilla at the infraorbital margin, providing structural support to the face.
Clinical significance[edit]
The infraorbital margin is a key landmark in various medical procedures. It is often used as a reference point in facial trauma assessment and reconstructive surgery. The infraorbital foramen, located just below the margin, is an important site for the passage of the infraorbital nerve and vessels, which supply sensation to the midface.
Surgical considerations[edit]
In orbital surgery, the infraorbital margin is a critical landmark for accessing the orbital floor. Surgeons must be cautious to avoid damaging the infraorbital nerve during procedures involving this area.
