1 CONCLUSION: Classification of fractures of roots of zygomatic arch is necessary.

2 Objective To study the practicability and the aesthetic significance of the treatment of the scalp coronal incision on all kinds of fracture of zygoma and zygomatic arch.

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 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.

6 Results The location, shape and displacement of fragment of zygomatic bone and zygomatic arch fractures were demonstrated stereoscopically through 3D images reconstructed from helical CT.

7 Method Tomouth - ray that 26 cases of the zygomatic arch fractures were treated by rigid internal fixation.

8 Objective:To evaluate the effectiveness of C-arm X-ray machine for treating zygomatic arch fracture.

9 Objective: To evaluate the effectiveness of the rigid internal fixation of zygomatic arch fracture by the upper zygomatic arch incision with the mini-plate.

10 Objective To observe the clinical effect of the beauty operation of forehead and down-eyelid with internal fixation of fracture of malar bone and zygomatic arch.

11 Methods:113 cases of midface fractures were reviewed. The nasal bone fracture, zygomatic arch fracture, optic nerve contusion, zygomatic maxilla fracture were treated.

12 Objective:To evaluate the possibility and effect of removal of the tumor invading lateral skull base in zygomatic arch and temporomandibular approaches.

13 Objective To investigate a new technique of reduction malarplasty for prominent malar complex and zygomatic arch.

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

15 Method:4 cases were extracted the tumor through approach of zygomatic arch and temporomandibular with microsurgical techniques.
