颧骨骨折手术复位和固定方法探讨

目的：探讨颧骨骨折的手术复位和固定方法。方法：对40例颧骨骨折病例依据颧牙槽嵴、颧额缝、眶下缘、颧颞缝及颧蝶缝中至少三点（骨折缝）参考进行手术复位,并用可吸收板或国产微型钛板加以固定,分析评价复位和固定的效果。结果：所有患者术后均一期愈合,其面形、咬合功能均获得满意效果。结论：颧骨骨折复位时应至少有三个点（骨折缝）的解剖复位作为理想复位的参考标准,单凭某一骨折线的复位标准不能完全指导或评价复位效果。颧骨骨折的固定,除非骨折移位不大或复位后颧骨再次移位可能性不大的患者外,最好行三点固位。

Investigation into Operative Reduction and Fixation of Zygomatic Fracture

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.
