![]() The frontal bone occupies the upper third of the anterior view of the skull. Various diagnostic possibilities for zygomatic arch pain: Seven case reports and review of literature. Where the anterior root joins the zygomatic arch, the latter has a. Atlas of neuroradiologic embryology, anatomy, and variants. Treasure Island (FL): StatPearls Publishing 2022. Treasure Island (FL): StatPearls Publishing 2022.Īltalib AA, Miao KH, Menezes RG. Don’t blow it! Extensive subcutaneous emphysema of the neck caused by isolated facial injuries: a case report and review of the literature. Characteristics and epidemiology of zygomaticomaxillary complex fractures. Optimizing the surgical management of zygomaticomaxillary complex fractures. Lee EI, Mohan K, Koshy JC, Hollier LH Jr. Ancestral variations in the shape and size of the zygoma. Approaches to the inferior orbital rim and orbital. The inferior orbital fissure - here it is from in front - separates the floor of the orbit, formed by the maxilla, from the lateral wall that’s formed by the sphenoid.Oettlé AC, Demeter FP, L'abbé EN. Extended preauricular approach to expose the whole zygomatic arch and the lateral aspect of the orbital rim. The horizontal part of the cleft is called the inferior orbital fissure. This technique helped achieve better exposure to view various deep anatomical locations around the posterior clinoid process, with minimal retraction of the. The vertical part of the cleft is called the pterygo-maxillary fissure. The facial bones series includes the: Caldwell view (OF15-20) view. The zygomatic arch series comprises the: Towne view. Down here the maxilla is joined to the bone behind it, the sphenoid bone.Īpart from this attachment the maxilla is separated from the sphenoid by this impressive cleft, which has a vertical part and a horizontal part. This case is an example of a normal zygomatic arch and facial bones. Here’s the back of the hollow part of the maxilla. This image shows the lateral view of the human skull. To see the posterior part of the maxilla, we’ll remove the zygomatic arch. The space inferior to the zygomatic arch and deep to the posterior mandible is the infratemporal fossa. It contains the largest of the paranasal sinuses, the maxillary sinus. To see the posterior part of the maxilla, we’ll remove the zygomatic arch. On the underside it forms much of the hard palate. ![]() On each side the maxilla forms the lower medial part of the orbital margin, and almost all of the floor of the orbit. ![]() The right and left maxillae are joined together in the midline. ![]() Now we’ll move forward and look at the maxilla. The zygomatic bone extends backward to meet the zygomatic process of the temporal bone, forming the zygomatic arch. It also forms the lower lateral part of the orbital margin, and this part of the lateral orbital wall. 'yoke'), also called cheekbone or malar bone, is a paired irregular bone which articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone. The zygomatic bone forms the bony prominence of the cheek. In the human skull, the zygomatic bone (from Ancient Greek:, romanized : zugn, lit. The hollow space is the frontal sinus, one of the paranasal sinuses, which we’ll look at shortly. The part of the frontal bone near the midline is hollow. The frontal bone also forms most of the floor of the anterior cranial fossa. The lower part of the frontal bone forms the beginning of the root of the nose, the upper part of the orbital margin, a small part of the temporal fossa, and a large part of the roof of the orbit. They're the frontal and zygomatic bones, the maxilla, the sphenoid bone, and the ethmoid bone. We’ll look at the five largest facial bones first. Zygomatic process of left temporal bone - inferior view.png 4,500 × 4,500 1.43 MB. Now that we’ve looked at the shape of the facial skeleton, and the parts of the cranium that it’s attached to, let’s look at the individual facial bones, and see how each of them contributes to the features that we’ve seen. ![]()
