目的

探讨颧弓根骨折的临床分类及治疗方法。

方法

将10 例颧弓根骨折患者根据其骨折线走向分为4 型。Ⅰ型：冠状骨折4 例；Ⅱ型：矢状骨折3 例；Ⅲ型：颞骨骨折1 例；Ⅳ型：颧弓根粉碎性骨折伴颧弓骨缺损2 例。 各自采用不同方法复位并坚强内固定重建颧弓形态，恢复颧面部外形。

结果

10 例患者均一期愈合，面部畸形得到明显改善，咬合关系恢复正常，无面神经损伤。

结论

采用不同形式的复位方法并坚强内固定治疗不同类型的颧弓根骨折，复位准确，固定可靠，可使颧面部解剖结构得以重建，恢复面宽和颧突高度。

Objective

To discuss the clinical classification and treatment of zygomatic arch root fractures.

Methods

According to the fracture line， 10 cases of zygomatic arch root fracture were divided into 4 types. Type Ⅰ： coronal fracture （4 cases）； type Ⅱ： sagittal fracture（3 cases）； type Ⅲ： temporal fracture （1 case） and type Ⅳ： comminuted fracture of zygomatic root companied with zygomatic arch defect （2 cases）. In order to reconstruct the zygomatic arch and facial appearance， all cases of complex zygomatic trauma were treated with different methods.

Results

All the incisions healed primarily， facial contours were satisfactory， occlusion became normal and no facial nerve damaged.

Conclusions

Different zygomatic root fractures could be managed in different ways. With accurate anatomic replacement and rigid internal fixation， the facial width and height of zygomatic process could be satisfactory restored.
