Dissection deep within the orbit is a cause for concern to surgeons because of the perceived risks of injuring critical structures such as the contents of the superior orbital fissure and the optic nerve. Although "safe distances" (those distances within which it is considered safe to dissect within the orbit) have been described, these are of limited value if the orbit is severely disrupted or is congenitally shallow. In addition, traumatic defects in the orbital floor, in particular, often extend beyond these distances. Reliable landmarks based on the relations between anatomical structures within the orbit, rather than absolute distances, are described that permit safe dissection within the orbit. We present the concept of the deep orbit and describe its relevance to repair of injuries.
由于存在损伤眶上裂内容物和视神经等关键结构的风险，眼眶深部解剖一直是外科医生关注的问题。尽管已经描述了“安全距离”（即在眼眶内进行解剖被认为是安全的距离），但如果眼眶严重受损或先天性浅小，这些距离的价值就有限。此外，尤其是眶底的创伤性缺损，往往超出这些距离。本文描述了基于眼眶内解剖结构之间关系而非绝对距离的可靠标志，这些标志可确保在眼眶内进行安全解剖。我们提出了深部眼眶的概念，并描述了其与损伤修复的相关性。
