Abstract:

Objective: To investigate the operative reduction route and fixation method of zygomatic fracture. Methods: According to at least three points （fracture line）of zygomaticomaxillary buttress, zygomaticofrontal suture, infraorbital margin, zygomaticotemporal suture and sutura zygomaticosphenoidalis, 40 cases of zygomatic fracture were repositioned and fixed by bioabsorbable plate and domestic miniature titanium plate. The effects of reduction and fixation were analyzed and evaluated. Rusults: All patients reached satisfactory outcome with ideal facial figure and occlusal functions. Conclusion: Operative reduction and fixation of zygomatic fracture should accord to at least three anatomic points （fracture line）as an ideal reference standard, reset effects could not be evaluate by the reposition of one fracture line alone. Zygomatic fracture fixation, unless in the condition of little displacement or unlikely displace again after reduction, three points fixation should be complied.

Key words: zygomatic fracture, operative reduction, fixation methods
