Traumatic blepharoptosis, although considered relatively rare, is an entity which demands recognition if one is to achieve optimal results. Reports of levator injury following orbital, ocular, and adnexal surgery, as well as in cataract and blepharoplasty procedures, are well described. In most cases eventuating in complete ptosis, levator disinsertion is the anatomic correlate, the ptosis is usually permanent, and surgical intervention is often indicated. We have observed two cases of transient, complete post-traumatic ptosis which have recovered by 6 weeks with expectant management. We believe this entity to be more pervasive than the current literature seems to reflect and emphasis is placed on nonoperative therapy. This paper reviews the anatomical considerations relevant to the function of the levator complex as well as the possible mechanisms for its injury.
创伤性上睑下垂虽然相对少见，但如果想要获得最佳治疗效果，就需要认识到这一病症。关于眼眶、眼部和附属器手术以及白内障和眼睑成形术之后提上睑肌损伤的报告已有详尽描述。在大多数导致完全性上睑下垂的病例中，提上睑肌断离是其解剖学关联因素，上睑下垂通常是永久性的，常常需要手术干预。我们观察到两例创伤后短暂性完全性上睑下垂病例，通过保守治疗在6周内恢复。我们认为这一病症比当前文献所反映的更为普遍，并且强调非手术治疗。本文回顾了与提上睑肌复合体功能相关的解剖学因素以及其损伤的可能机制。
