The zygomatic bone is denser in quality and more cortical in nature than posterior maxillary bone. [5] Because of the sturdy anchorage achievable in the dense bone of the zygomatic region, and the wide stress distribution achieved on these tilted implants, a prosthesis can often be immediately placed at the time of surgery. [6] The zygoma ...
Zygoma reduction, also known as cheekbone reduction surgery, is a surgery used to reduce the facial width by excising part of the zygomatic bone and arch. Wide cheekbones are a characteristic facial trait of Asians, whose skull shapes tend to be more brachycephalic (broad, short skull) in comparison with Caucasian counterparts, whose skull shapes tend to be more dolichocephalic (narrow and ...
In the human skull, the zygomatic bone (from Ancient Greek: ζῠγόν, romanized: zugón, lit. 'yoke'), also called cheekbone or malar bone, is a paired irregular bone, situated at the upper and lateral part of the face and forming part of the lateral wall and floor of the orbit, of the temporal fossa and the infratemporal fossa.
Fractures with displacement require surgery consisting of fracture reduction with miniplates, microplates and screws. Gillie's approach is used for depressed zygomatic fractures. [5] The prognosis of tripod fractures is generally good. In some cases there may be persistent post-surgical facial asymmetry, which can require further treatment. [6]
The procedure is often indicated during reconstructive surgery for birth defects or traumatic injury. During this procedure, the zygoma, or cheekbone, is separated by bone cuts near the orbital rim and maxilla. The bone is then moved outward and a solid material, such as hydroxylapatite, is wedged in place to hold the new position of the zygoma ...
It comprises the maxillary bone, palatine bones, zygomas, zygomatic processes (of the temporal bone), ethmoid bone, vomer, nasal concha, nasal bones, and pterygoid processes (of the sphenoid bone). [2] [3] [4] The maxillary bone contains important anatomical structures which are prone to injury during trauma.
The bone-anchored hearing aid is an alternative for individuals with ear anomalies. [38] Zygomatic and orbital reconstruction is performed when the cranio-orbitozygomatic bone is completely developed, usually at the age of 5–7 years. In children, an autologous bone graft is mostly used.
A craniotomy is a surgical operation in which a bone flap is temporarily removed from the skull to access the brain.Craniotomies are often critical operations, performed on patients who are suffering from brain lesions, such as tumors, blood clots, removal of foreign bodies such as bullets, or traumatic brain injury, and can also allow doctors to surgically implant devices, such as deep brain ...
