眼眶爆裂性骨折是眶部挫伤所致的眶壁骨折,由Mackenzie于1844年首先提出,Smith和Regan于1957年命名,它系由直径大于眶口(有人提出直径大于5 cm)的物体钝性打击眼眶软组织和眶缘,使眶内压突然升高,引起眶壁最薄弱处(如眶内壁和下壁)向外爆裂所致,而眶缘完整。由于常伴有眶内容物
Orbital blowout fractures are orbital fractures caused by orbital contusion and were first proposed by Mackenzie in 1844. Smith and Regan were named in 1957 and consisted of blunt objects of diameter greater than the orbital orifice (some proposed diameters greater than 5 cm) Combining orbital soft tissue and orbital margin, orbital pressure suddenly increased, causing the weakest orbital wall (such as the orbital wall and the inferior wall) due to burst out, and orbital rim integrity. As often accompanied by orbital contents
