面中部骨折约占颌面部骨折的40%以上,由于邻近颅底,常伴发颅脑损伤。在颌面部的组织结构中,面中部骨骼的解剖结构最为复杂。因面中部与眼眶相邻,颧骨复合体骨折、上颌骨LeFortⅡ型和Ⅲ型骨折、鼻眶筛骨骨折等面中部骨折时常伴发眶底骨折,从而可造成严重的眼功能障碍,包括复视、眼球内陷、眼球运动障碍、视力下降等。 Central face fractures account for about 40% of maxillofacial fractures, due to the adjacent skull base, often accompanied by craniocerebral injury. In the maxillofacial tissue structure, the anatomy of the midface bone is the most complex. Due to the middle of the face and the orbit adjacent, zygomatic complex fractures, maxillary LeFort Ⅱ and Ⅲ fractures, nasal orbital ethmoid fracture midface fracture often accompanied by orbital floor fractures, which can cause serious eye dysfunction, including complex Visual, eye retraction, eye movement disorders, decreased vision and so on.
