How do you treat a zygomatic arch fracture?
Surgical intervention is an effective treatment modality of depressed zygomatic complex fractures, whereas a nonsurgical approach is often used for nondisplaced fractures. Most zygomatic complex fractures can be treated solely by an intraoral approach and rigid fixation at the zygomaticomaxillary buttress.
Which is the most common site for fracture in zygomatic arch fracture?
The present study recorded more fractures of the zygomatic bone 57.7% than those of the zygomatic arch 13.8% or combined zygomatic bone and arch 28.4%. This was probably because of the predominant role of road traffic accidents, in which most impacts to the face were most likely frontal.
What is zygomatic arch fracture?
Zygomatic arch fractures After the nasal bone, the zygoma is the second most common bone of the face to be fractured. The group at highest risk is young males. Aetiology is usually blunt trauma to the cheek, such as involved in: Assault. Road traffic accidents.
How is zygomatic arch fracture diagnosed?
Zygomatic arch fractures can be clinically difficult to diagnose as the only signs may be a dimple palpable on the arch, which may or may not be tender, and or a decreased range of mouth opening. The patient’s range of mouth opening should be greater than 30 mms.
What is the pathophysiology of zygomatic arch fractures?
Zygomatic arch fractures may produce a visible depression of the malar eminence leading to cosmetic asymmetry, enophthalmos, dystopia as well as trismus if the arch impinges upon the coronoid process.
Can the zygomatic arch be fixed?
If the zygomatic arch is properly elevated (in an isolated zygomatic arch fracture), and the periosteum has been left intact, the arch will commonly retain its reduction. Unless a surgeon is willing to perform a coronal approach, or has endoscopic facilities for plating the zygomatic arch, an internal fixation is not possible.
What is the external fixation technique for a zygomatic fracture?
Goldsmith and Fry also described an external fixation technique using an aluminum finger splint. 9In this technique, two 2-0 nylon sutures are passed through the skin around the fracture zygomatic arch with a large, heavy curved needle. A finger is placed intraorally to facilitate accurate direction of the needle under the arch.
When is open treatment indicated for a zygomatic arch fracture?
It may be particularly desirable in a patient where a coronal approach has to be made for other reasons (such as for the treatment of a frontal sinus fracture or the harvest of a split calvarium bone graft). Another reason for open treatment is secondary treatment of a zygomatic arch malunion where osteotomy and internal fixation are needed.
