What happens if the zygomatic bone is damaged?
Fractures of the ZMC or zygomatic arch can often lead to unsightly malar depression, which should be corrected to restore a normal facial contour. ZMC fractures can also cause significant functional issues, including trismus, enophthalmos and/or diplopia, and paresthesias of the infraorbital nerve.
What does the zygomatic nerve do?
The zygomatic nerve is a branch of the maxillary nerve, itself a branch of the trigeminal nerve (CN V). It travels through the orbit and divides into branches that provide sensory innervation to skin over the zygomatic and temporal bones.
Why does my zygomatic arch bone hurt?
Zygomatic arch pain is commonly reported by patients visiting the orofacial pain clinic and is majorly accepted to be caused by masseter muscle pain. But a variety of conditions may present as orofacial pain in the zygomatic arch region, including life-threatening diseases such as salivary gland tumors.
How do you fix zygomatic arch?
Most zygomatic complex fractures can be treated solely by an intraoral approach and rigid fixation at the zygomaticomaxillary buttress. Further exposure of the zygomaticofrontal junction or inferior orbital rim is necessary for severely displaced fractures, which require additional fixation.
What is a 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.
Which complication can result from a Zygoma fracture?
Malunion is the most common complication of zygomatic fractures and is the result of improper reduction and fixation, resulting in malocclusion, facial asymmetry, and enophthalmos.
Where is the zygomatic nerve located?
pterygopalatine fossa
The zygomatic nerve originates in the pterygopalatine fossa, and it then passes into the orbit via the inferior orbital fissure. It then runs on the outer wall of the orbit and terminates as two branches—the zygomaticotemporal and the zygomaticofacial nerves.
Where is the zygomatic arch?
zygomatic arch, bridge of bone extending from the temporal bone at the side of the head around to the maxilla (upper jawbone) in front and including the zygomatic (cheek) bone as a major portion.
How long does it take for a zygomatic bone to heal?
Even if the position of the fractured bone has been held with plates and screws it still takes about six weeks for your cheekbone to heal completely. During this time you need to be careful to avoid an injury to this side of your face, since it may well push the cheekbone back out of position again.
How long does a zygomatic fracture take to heal?
They will heal themselves over 3-6 weeks. want to bring the broken bones back into a normal alignment (called ‘reducing’ the fracture) and keep it/them in this place (called ‘fixing the fracture’), preventing further injury.
What is zygomatic arch fracture?
Is the zygomatic arch the same as the zygomatic process?
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.
What are the possible complications of zygomatic arch fractures?
Fractures of the ZMC or zygomatic arch can often lead to unsightly malar depression, which should be corrected to restore a normal facial contour. ZMC fractures can also cause significant functional issues, including trismus, enophthalmos and/or diplopia, and paresthesias of the infraorbital nerve.
What is the zygomatic nerve?
The zygomatic branch or a branch of the zygomatic branch of the facial nerve, as it courses to the deep aspect of the middle of the zygomaticus major muscle, runs deep and inferior to the origin of the zygomatic ligaments.
How are zygomatic and ZMA fractures repaired?
Several methods exist to repair zygomatic arch and ZMA fractures, though closed reduction may be adequate for simple, low-velocity injuries of the zygomatic arch (see TYPE A1 below) that are non-displaced or minimally displaced and remain stable after initial attempts of reduction [2] .
What is the pathophysiology of zygomatic fracture of the skull?
Fractures of the zygomatic bone can present with complicated aesthetic and neurological pathology. Specifically, management of isolated zygomatic fracture has been sparsely discussed in the literature, and most studies are based upon older techniques.
