Is hitting cheekbone easy fracture?

summary

Zygoma and zygomatic arch are prominent parts of the face, which are vulnerable to impact and fracture. Zygomatic bone is associated with maxilla, frontal bone, sphenoid bone and temporal bone, among which the joint surface with maxilla is the largest. Is hitting zygomatic bone easy to fracture? Tell everybody about below?

Is hitting cheekbone easy fracture?

After zygomatic bone and zygomatic arch fracture, the displacement direction of the fracture block mainly depends on the direction of the external force, and most of them are invaginated. In the early stage after injury, zygomatic facial depression can be seen. Subsequently, due to local swelling, depression deformity is not obvious, which is easy to be mistaken for simple soft tissue injury. After a few days, the swelling subsided and local collapse appeared.

After zygomatic fracture displacement, diplopia can be found due to eye displacement, abducens muscle bleeding and local edema, as well as tear of the anterior oblique muscle embedded in the fracture line, limiting eye movement and other reasons.

Because of the displacement of the fracture block, the temporalis and masseter muscles are compressed, and the movement of the coracoid process is hindered, resulting in pain and limitation of mouth opening. The fracture of the maxillary process of the zygoma may damage the infraorbital nerve, causing numbness in the innervated area. If zygomatic branch of facial nerve is injured at the same time, eyelid insufficiency will occur.

matters needing attention

If there is only slight displacement, no obvious deformity, no limitation of mouth opening, diplopia and other dysfunction after zygomatic bone and zygomatic arch fracture, surgical treatment can not be performed. All patients with limited mouth opening should be operated on. Although there is no dysfunction and there is significant deformity can also be considered for surgical reduction.
