Results of early combined maxillo-facial and neurosurgical treatment of 53 craniofacial fractures are referred. The fracture location was in 31 cases central midfrontal, 10 lateral supraorbital and 12 combined central and lateral fractures. 35 fractures interested the floor and the posterior wall of frontal sinus, lacerating the underlying dura and cortical tissue. In 19 fractures orbital displacement was present. The key points in the management of these patients are: 1) Early (within 1 to 5 days) and one stage neurosurgical-maxillofacial procedure. Immediate intervention is indicated only in case of evolutive neurological lesions; 2) wide exposition of all the injuries through bicoronal incision and bone flap; 3) assessment of fractures pattern and amount of bone loss; 4) reconstruction of craniofacial frame with osteosynthesis and autologous bone grafts (35 cases iliac crest, 7 split calvarial graft); 5) interosseous wiring is used in sutured mosaic, small bone fragments and intraoperative temporary fixation; miniplates are used for rigid fixation of craniofacial pillars; 6) for optimal cosmetic result reconstruction of supraorbital ridge, nasoglabellar region and zygomatic arch is essential; 7) fractures involving the sinus floor, posterior wall and the nasofrontal duct result in direct communication between the nose and intracranial cavity with high risk of infection and mucocele formation. Cranialization of the sinus removing the posterior wall and all the mucosa is mandatory. The nasofrontal duct, the floor and sinus dead space are obliterated with autologous bone chips. Osteoneogenesis occurred in all the cases.
报告了53例颅面骨折早期联合颌面与神经外科治疗的结果。骨折部位:31例位于中央额中部,10例位于眶上外侧,12例为中央和外侧联合骨折。35例骨折累及额窦底部和后壁,撕裂了下方的硬脑膜和皮质组织。19例骨折存在眼眶移位。这些患者治疗的关键点包括:1)早期(1至5天内)一期神经外科 - 颌面手术。仅在出现进行性神经损伤时才进行立即干预;2)通过双冠状切口和骨瓣广泛暴露所有损伤部位;3)评估骨折类型和骨丢失量;4)采用骨内固定和自体骨移植重建颅面框架(35例取自髂嵴,7例取自劈开的颅骨);5)在缝合镶嵌、小骨碎片和术中临时固定时使用骨间结扎;微型钢板用于颅面支柱的坚固固定;6)为获得最佳美容效果,眶上嵴、鼻根区域和颧弓的重建至关重要;7)累及鼻窦底部、后壁和鼻额管的骨折会导致鼻腔与颅内腔直接相通,有感染和黏液囊肿形成的高风险。必须切除后壁和所有黏膜进行鼻窦颅骨化。鼻额管、底部和鼻窦死腔用自体骨屑填塞。所有病例均发生了骨生成。
