The zygomatic bone, also known as the cheekbone or malar bone, is a facial bone that plays a crucial role in the structure and function of the human face. It is located in the front part of the skull, just below the eye socket and above the jaw. The zygomatic bone is a paired bone, meaning that there is one on each side of the face.
The temporal process of the zygomatic bone is a part of the bone that projects backward and downward from the main body of the bone. It articulates with the temporal bone of the skull, which is located just above and behind the ear. This articulation forms the zygomaticotemporal suture, which is a joint that allows the zygomatic bone to move slightly when we make facial expressions such as smiling or frowning.
The development of the zygomatic bone begins in fetal development, around the sixth week of gestation. At this stage, the bones of the face are formed from a process called intramembranous ossification, which involves the differentiation of mesenchymal cells into bone cells. The zygomatic bone initially forms as two separate pieces, known as the maxillary and temporal processes, which later fuse together during the third trimester of fetal development.
After birth, the zygomatic bone continues to grow and develop along with the rest of the face. It reaches its final adult size and shape around the age of 18 to 20 years. However, the bone can continue to undergo changes throughout the lifespan due to factors such as aging and the effects of gravity.
The zygomatic bone has several important functions in the human body. It plays a role in the structure of the face, contributing to the shape and contour of the cheek and eye socket. It also helps to support the muscles of facial expression, which attach to the bone and allow us to make various facial expressions. In addition, the zygomatic bone provides a protective function for the eye, acting as a shield to protect it from injury.
In summary, the temporal process of the zygomatic bone is a key part of this facial bone that plays a vital role in the structure and function of the face. It forms during fetal development and continues to grow and develop throughout life, providing support for the muscles of facial expression and protecting the eye from injury.

Frontal process of zygomatic bone The frontal process originates from the upper margin of the zygomatic bone. This kind of injury often happens during a car accident or due to being punched in the face with a fist. They belong to Waretown methods. And I'm not bad at telling you about it. Zygomatic process of the frontal bone is connected with it. Anterosuperior or Orbital Border: Smooth, concave, and present between the lateral and orbital surfaces of the bone. Structure Zygomatic bone is a rectangular flat element.
The First of these convex. It is Also noteworthy that through the orbital part of the bone using a thin probe is accessed via a perforating channel in the bone in the zygoma-the temporal and zygoma-facial orifice.

Facial or Malar Surface Also known as the lateral surface as it faces outwards. It is located on the rear edge of the upper third of the bone, called the skull. At the same problems appear when trying to open your mouth or make lateral movement of the lower jaw.
Orbital bone. The temporal process of the zygomatic bone
Anteroinferior or Maxillary Border: Articulates with the upper jawbone, maxilla on both sides via the zygomaticomaxillary suture. The condyles are located at the distal end of the bone. Gray's Anatomy 41tst ed. The depression in the head of the femur is called the fovea. Through the incision, a Elevator under the zygomatic arc or bone, it is introduced under gauze.
Temporal Process of Zygomatic Bone : A backwardly directed bony projection, having an oblique, serrated end. Using exposed seams, can be fixed to the zygomatic arch. Also, fractures are accompanied by hemorrhages in the retina and loss of sensation, numbness in the infraorbital nerve area. Posterosuperior or Temporal Border: A sinuous border with a convex top and concave bottom. It articulates with the zygomatic process of frontal bone superiorly via the zygomaticofrontal suture, and with the greater wing of sphenoid bone posteriorly via the sphenozygomatic suture.
In ninegates part and in the area of the zygomatic arch can be seen the so-called step. This canal branches into the zygomaticofacial and zygomaticotemporal canals, which open on the corresponding surfaces of the zygomatic bone explained above. Which is not correct regarding the femur? More specifically, it is positioned just below each eye, extending upward to the outer side of each eye and downward near the jaw. Thoracic - cervical - lumbar - coccygeal - sacral Which statement accurately describes the articulations between ribs and vertebrae? The zygomaticotemporal foramen is also present on this surface.

When performing the indicated operation, it is also possible to reposition of fragments of the bottom of the sockets. Fractures The second most common area of fracture in the face is the fracture of the zygomatic bone, especially of the left frontal process. The temporal fascia also attaches here.
It is smooth and convex, and it features a small opening called the zygomaticofacial foramen. Between the articular surfaces, there is a small free surface of the posteromedial margin that comprises the lateral border of the inferior orbital fissure. In this case, after restoring the integrity of the surface of the bone at the author recommended to apply wire suture at the lower edge of the orbit, where the frontal process of the zygomatic bone. For this it is necessary to limit the movement of the mouth, to eat liquid and soft foods, do not sleep on the affected side of the face. It articulates with the frontal bone above and the greater wing of sphenoid posteriorly via the zygomaticofrontal, and sphenozygomatic sutures, respectively.

Chin pointed and triangular B.
To restore the integrity of the bone incision in the area of the transition folds of the alveolar process. It is smooth and convex, and has a small opening, the zygomaticofacial foramen, which allows passage to the zygomaticofacial nerve, vein, and artery from the face to the orbit. The human bone manual by Tim D. It is smooth, convex shape with a special hill and zygoma-facial hole. Posteriorly, it is continuous with the orbital surface of the bone.
