闭合性颧骨上颌骨粉碎性骨折是临床较常见的颌面外伤,一般多采用内固定的方法整复,但因其缺乏支持难以做到将多发性骨折线对位固定,术后仍遗有不同程度的面部畸形。根据模型外科原理,我们用自凝塑胶研制成面部体外周定器治疗颧骨合并上颌窦前壁粉碎性凹陷骨折面部塌陷畸形,取得满意效果,兹报告如下: Closure maxillary comminuted fracture of the maxillary jaw is more common in clinical maxillofacial trauma, the general use of internal fixation method of consolidation, but because of its lack of support is difficult to be fixed multiple fracture line alignment, still left after surgery Different degrees of facial deformity. According to the surgical principle of the model, we developed a self-curing plastic facial peripheral device for the treatment of zygomatic merger of the maxillary anterior wall comminuted facial collapse fractures, and achieved satisfactory results, it is reported as follows:
