[Treatment of fractures of zygomatic bone and zygomatic arch. A method for the reduction of fracture by the use of U-shaped elevator].

The occurrence of maxillofacial bone fractures has gradually increased. These were two-hundred-fifty-nine cases of maxillofacial bone fractures from 1981 to 1988, in which fourteen cases were fractures of zygomatic bone and zygomatic arch. (The number of the fractures of zygomatic bone, zygomatic arch, zygomatic bone and arch, and zygomatic bone and mandibular bone were 5, 2, 4, and 3 cases, respectively). Pathognomonic symptoms were infra-orbital neuroparalysis, tristmus and recess of the buccal region. The incisional for open reduction were applied for the lateral brow, the lower eyelid, or intra-oral approach. U-shaped elevator was used for the reduction and miniplate and stainless wire were used for fixation.
