For zygomatic fracture, we need professional examination to confirm the diagnosis. Palpation of the fracture may be localized with pressure pain, collapse and displacement, and there may be a step formation at the zygomatic-frontal suture, zygomatic-maxillary suture bone junction, and infraorbital rim. If the fracture is palpated from inside the mouth along the vestibular sulcus and posteriorly, the space between the zygomatic bone and the maxilla and rostral process can be examined to see if it has become smaller. All of these are helpful in the diagnosis of zygomatic fractures. Therefore, even if a zygomatic fracture occurs, we can still carry out other activities as usual. Some people may even find out that they have symptoms of zygomatic fracture later, so it is better for us to go to the hospital for examination. Zygomatic arch fracture can be clearly diagnosed based on the history of injury, clinical features and radiographic examination. On palpation, the fracture may have localized pressure pain, collapse and displacement, and there may be a step formation at the zygomatic-frontal suture, the zygomatic-maxillary suture bone junction, and the infraorbital rim. If the fracture is palpated from inside the mouth along the vestibular sulcus and posteriorly, the space between the zygomatic bone and the maxilla and rostral process can be examined to see if it has become smaller. These are helpful in the diagnosis of zygomatic fractures. Radiographs are often taken in the nasal-chin and zygomatic arch positions. In the nasal-chin position, the fracture of the zygoma and zygomatic arch can be seen, and the orbit, maxillary sinus, and infraorbital foramen can also be observed. In the zygomatic arch position, the fracture and displacement of the zygomatic arch can be clearly shown.
