What is zygomaticofrontal suture?
The zygomaticofrontal suture (or frontozygomatic suture) is the cranial suture between the zygomatic bone and the frontal bone. The suture can be palpated just lateral to the eye.
What are the processes of zygomatic bone?
Processes of the zygomatic bone The zygomatic bone itself has four processes, namely the frontosphenoidal, orbital, maxillary and temporal processes. The frontosphenoidal process is thick and serrated. The cranial suture between the frontal and zygomatic bone is found here.
What is the frontal process of zygomatic bone?
Frontal process of zygomatic bone The frontal process features a bony tubercle on its orbital surface called the Whitnall’s tubercle, which serves as an attachment site for the lateral palpebral ligament, suspensory ligament of the eye, and the aponeurosis of levator palpebrae superioris muscle.
How many bones have a zygomatic process?
The zygomatic bones (Gr., zygoma – yoke) are two facial bones that form the cheeks and the lateral walls of the orbits. They are also commonly referred to a as the cheekbones or malar bones (L., mala – the cheek). Each zygomatic bone articulates with the temporal bone, frontal bone, maxilla, and sphenoid bones.
What is tripod fracture?
They are the second most common facial bone fracture after nasal bone injuries. The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma.
Where is the Palatine process?
The palatine process (Processus palatinus) of the maxilla is a strong bony blade that arises perpendiculary from the nasal surface of the maxilla, near its ventral border; it unites with the palatine process of the opposite maxilla on the median plane through the palatine suture (Sutura palatina).
What is the difference between the zygomatic process and the zygomatic arch?
Zygomatic Arch Definition The zygomatic arch is formed from parts of both the zygomatic bone and the temporal bone. The extension of the temporal bone is known specifically as the zygomatic process, and attaches directly to the similarly shaped process on the zygomatic bone.
Why is it called the zygomatic process?
Specifically, it is the main protrusion of bone that forms the prominence of the upper cheek, the cheekbone. This process is called the zygomatic process because the zygomatic bone forms the majority of it, but the maxilla, temporal and frontal bones also contribute to the protrusion.
Why is it called zygomatic?
The zygomatic bone is also known as the zygomatic arch, the zygoma, the malar bone, the cheek bone and the yoke bone. The word “zygomatic” comes from the Greek “zygon” meaning a yoke or crossbar by which two draft animals such as oxen could be hitched to a plow or wagon.
What is zygomaticomaxillary fracture?
Zygomaticomaxillary Complex (ZMC) fractures result from blunt trauma to the periorbital area (viz. malar eminence). ZMC fractures are also referred to as tripod, trimalar, tetrapod, quadripod, or malar fractures.
What is tripod surgery?
Zygomaticomaxillary Complex Fracture (Tripod Fracture) Indications – generally aimed at realignment of mid face skeleton with restoration of relative symmetry including projection of malar eminence, as well as restoration of unrestricted motion of the globe and mandible.
Why is it called tripod fracture?
The zygomaticomaxillary complex fracture, also known as a quadripod fracture, quadramalar fracture, and formerly referred to as a tripod fracture or trimalar fracture, has four components, three of which are directly related to connections between the zygoma and the face, and the fourth being the orbital floor.
What is the function of the Palatine process?
Palatine bone
| Parts | Horizontal plate, perpendicular plate, pyramidal process, orbital process, sphenoidal process |
|---|---|
| Function | Participates in the formation of the: Nasal cavity Hard palate Orbit (floor) Pterygopalatine fossa Pterygoid fossa (inferior part) |
What is the difference between the Palatine process and the palatine bone?
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest.
What is the function of zygomatic process?
The function of the zygomatic arch is protection of the eye, origin for the masseter and part of the temporal muscles, and to provide an articulation for the mandible.
What is the difference between zygomatic arch and zygomatic process?
The zygomatic arch is formed from parts of both the zygomatic bone and the temporal bone. The extension of the temporal bone is known specifically as the zygomatic process, and attaches directly to the similarly shaped process on the zygomatic bone.
