What symptom does face hit fracture have?

summary

In clinical practice, all fractures involving two or more parts including midface fractures, which result in changes of three-dimensional facial stent, can be considered as total fractures. It is difficult to operate because of the wide range of destruction and the loss of anatomic landmarks. What symptom does face hit fracture have? Let's talk about it

What symptom does face hit fracture have?

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.

When there is a closed fracture of the zygomatic orbital wall, there may be hemorrhagic ecchymosis under the periorbital skin, eyelid and conjunctiva. 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

The treatment of zygomatic bone and zygomatic arch fracture is mainly surgical reduction. After zygomatic bone and zygomatic arch fracture, all patients with dysfunction should be treated with reduction. If there is no displacement or no obvious displacement and no dysfunction, special treatment is not necessary. After reduction of zygomatic bone and zygomatic arch fracture, in order to prevent the fracture segment from shifting again, mouth opening movement should be appropriately limited to avoid collision, and healthy lateral position should be used during sleep.
