78 cases of zygomatic orbital fracture, 59 males and 19 females. Age 17 ~ 53 years old. Among them, 67 cases (86%) had closed craniocerebral injury (concussion, mild brain contusion) and 73 eyes (93.5%) had ocular injury. Fractures were divided into 4 types: type Ⅰ in 7 cases, infraorbital margin and maxillary anterior wall fracture. Type Ⅱ 13 cases, after the zygomatic frontal fracture along the vertical axis of rotation. Type Ⅲ 27 cases, after zygomatic ridge along the oblique axis of rotation of the fracture. Type Ⅳ in 31 cases, fractures embedded in the maxillary sinus. Oval parentheses are made of temperature-memory nickel-titanium alloy wire with a thickness of 0.6 ~ 0.8 mm. The clip length is 6 ~ 10 mm. The length of the clip foot (the part fixed in the bone hole) is 3 ~ 6 mm. 1.2 kg. Card holder for linear fractures. In a bone defect with a small splint, splint length 15 ~ 30 mm,
