1. So zygomatic bone may be suitable anchorage for inhibiting maxillary growth.

2. The height of the zygomatic bone of modern Europeans in smaller than that of Huabei skulls, but is similar as Yunnan's.

3. Superior buccal gingival sulcus incision dissection was made inferior to zygomatic bone and zygomatic arch periosteum.

4. Conclusion 3D helical CT imaging can provide valuable information in demonstrating the space relationship of zygomatic bone and zygomatic arch fractures.

5. Results The location,[http://] shape and displacement of fragment of zygomatic bone and zygomatic arch fractures were demonstrated stereoscopically through 3D images reconstructed from helical CT.

6. Methods Based on the former instrument for rapid tiny-hurt traction, reposition and fixation of fracture of zygomatic bone, various aspect have been improved.

7. Objective To develop facility instrument for rapid tiny-hurt traction, reposition and fixation of fracture of zygomatic bone .

8. Methods On 100 cranial bones according to specified methods using vernier to measure the subcutaneous segment of each bone suture that is made by zygomatic bone and approximal bone.

9. Objective To explore a new method and the feature of traumatism in sheep for zygomatic bone comminuted fracture by Bio impact device.

10. OBJECTIVE: To explore the design and manufacture of 3-D external distractor for zygomatic bone.
