Abstract：
Plate fixation to zygomatic arch fractures carries the risk of facial nerve palsy and scarring of the cheek; however, without plate fixation, bone deviation or displacement may reoccur after surgery. Furthermore, zygomatic arch fractures combined with zygomatic body fractures are more postoperatively unstable than single zygomatic arch fractures. Few reports have focused on this combined fracture type, and no consensus has been reached regarding treatment. Because plate fixation for slight deviation of the zygomatic body has little advantage for stabilization, the authors, usually opt for transmalar pinning alone instead of plate fixation at the hospital. This study is a retrospective case series of 7 patients, among 100 zygomatic fractures excluding isolated zygomatic arch fractures, treated using transmalar pinning under ultrasound scanning. The reduction was performed through the oral and temporal incision as a surgical procedure. Under ultrasound observation, a Kirshner wire was inserted into the zygomatic body from the unaffected side while maintaining the reduced position. The wire was removed at an outpatient visit 2 to 3 months following surgery. In all cases, the zygomatic body was of the laterally rotated type, and postoperative morphologic evaluation showed improvement without postoperative complications. Scores were higher in middle-aged and older than in young people. Correction of zygomatic rotation also scored higher than zygomatic arch morphology. Transmalar Kirshner wire fixation under ultrasound observation is a simple and minimally invasive method for zygomatic arch fractures, which avoids the possible complications related to plate fixation.
摘要：
骨弓骨折的钢板固定会带来面神经麻痹和脸颊疤痕的风险；然而，没有钢板固定，骨偏移或移位可能在手术后复发。此外，骨弓骨折合并骨体骨折比单个骨弓骨折更不稳定。很少有报道关注这种合并的骨折类型，在治疗方面没有达成共识。由于骨体轻微偏离的钢板固定对稳定几乎没有优势，作者,通常在医院选择单独的经线钉扎，而不是钢板固定。这项研究是7例患者的回顾性病例系列，在100例颧骨骨折中，不包括孤立的颧弓骨折，在超声扫描下使用经线钉扎治疗。复位是通过口腔和颞部切口作为外科手术进行的。在超声观察下,从未受影响的一侧将Kirshner线插入zy骨体内，同时保持降低的位置。在手术后2至3个月的门诊就诊时移除导线。在所有情况下,the体属于横向旋转型，术后形态学评估显示无术后并发症。中年人和老年人的分数高于年轻人。the骨旋转的校正得分也高于the骨形态。超声观察下经颌骨Kirshner钢丝内固定术是一种简便、微创、这避免了与钢板固定相关的可能的并发症。
