1·Abstract: Osteoradionecrosis occurs more often in the mandible than maxilla, and rarely occurs in the zygoma.

摘要颌面骨的放射性骨坏死多发于下颌骨，少数发于上颌骨，而颧骨的放射性骨坏死非常罕见。

2·The anterior portion of the supramastoid crest and zygoma root correlated with the level of the middle fossa.

颧弓、乳突上嵴与其相对应的颅中窝底相平。

3·Objective: to assess the treatment result of reposition and fixation to orbital maxillary zygoma complex fractures.

目的：探讨眶上颌颧骨复合骨折复位固定的治疗效果。

4·Results: Measurement results showed that the displacement of the zygoma segment in most patients was backward and inward.

重点对颧突点和颧弓突点进行了测量。 测量结果发现颧骨复合体骨折时，颧骨体骨折块多向后、向内移位。

5·AIM: To observe the effect of distraction osteogenesis of zygoma based on the bony structure and bony density of new bone formation.

目的：通过新生骨骨质结构和骨密度分析观察犬颧骨牵张成骨效果。

6·The four approaches used in orbital-maxillary-zygoma complex fracture can result in satisfactory plastic effect and functional recovery.

结论采取这四种手术进路治疗眶-上颌-颧骨复合骨折，可以得到良好的整复效果和功能恢复。

7·Objective: To present the details of orbital-maxillary-zygoma complex fracture (OMZ), treatment timing and the selection of managements.

目的详细阐述眶-上颌-颧骨复合骨折的解剖学基础、治疗时机和治疗方案的选择。

8·Objective: To study the effects of coronal operative incision in hairline scalp on reconstruction of bones shape after the fracture of zygoma.

目的：观察头皮冠状切口在颧骨颧弓骨折中重建骨骼形态的效果。

9·Method: The method of coronal incision in hairline scalp was used in bones repositioning and immobilization for 21 patients with fracture of zygoma.

方法：应用发际内头皮冠状切口进路对21例颧骨颧弓骨折病例进行复位和固定，分析其治疗方法的优越性、效果、并发症及预防措施。

10·Objective To investigate the value of scalp coronal incision in jaw fractures, especially in maxillofacial zygoma, zygomatic arch, orbital fractures.

目的探讨头皮冠状切口在颌骨骨折中的应用价值，尤其是对颌面部颧骨、颧弓、眶周骨折中的应用。

1·Methods: According to the mirror imaging symmetry principle, we assumed the skull as an entirety and design the localizer to measure the projections of zygoma and zygomatic arch.

方法：视头颅为一整体，根据镜像对称性原理，制成由面弓、滑动定位尺、轨限、耳杆和额托等附件构成的颧骨复合体骨折定量复位校正仪。

2·Objective: to assess the treatment result of reposition and fixation to orbital maxillary zygoma complex fractures.

目的：探讨眶上颌颧骨复合骨折复位固定的治疗效果。

3·Objective: to explore the method to construct three-dimensional finite element model for maxillary posterior-tooth area, maxillary sinus, zygoma and zygomatic implant.

目的：探讨上颌骨后牙区、上颌窦、颧骨及颧骨种植体的三维有限元建模方法。

4·Abstract: Osteoradionecrosis occurs more often in the mandible than maxilla, and rarely occurs in the zygoma.

摘要颌面骨的放射性骨坏死多发于下颌骨，少数发于上颌骨，而颧骨的放射性骨坏死非常罕见。
