鼻眶筛骨折不同于鼻骨骨折,是指联合发生于鼻、筛窦、内眶区的骨折。鼻眶筛区骨折可以单独发生,也可以伴发颅面其他骨折。由于鼻眶筛区解剖结构复杂,且与眶、颅等重要结构相邻,其创伤的治疗是一个临床难点。大部分鼻眶筛骨折是由机动车交通事故造成。 Nasal orbital ethmoid fracture is different from the nasal bone fracture is the joint occurred in the nose, ethmoid, orbital area of ​​the fracture. Nasion orbital sieve fracture can occur alone, can also be associated with craniofacial other fractures. As the nasal orbital sieve anatomical structure is complex, and orbital, cranial and other important structures adjacent to the trauma treatment is a clinical difficulty. Most naso-orbital ethmoidal fractures are caused by motor vehicle accidents.
