Transient traumatic isolated neurogenic ptosis (TTINP) is a sporadically reported rare entity. However, to the best of our knowledge, nearly all the reported cases are either secondary to direct periorbital trauma or surgery. We would like to report on a case of TTINP with countre-coup injury of the periorbital region.
A 49-year-old female slipped and fell down while walking. She was hospitalized with a moderate headache and undisturbed mental state. The patient recalled that the force bearing point was her occipital region. Physical examination and computed tomography (CT) on admission showed right isolated ptosis and mild contusion and laceration in the bilateral frontal cortex. Further radiological investigation revealed nothing remarkable except for a fracture of the superior portion of the right medial orbital wall. She was managed conservatively and recovered completely in two months.
TTINP might manifest as a unique entity with a relatively mild, reversible, and non-devastating injury to the terminal branch of the oculomotor nerve and for which perhaps no special treatment is needed. The proposed mechanism is injury of the terminal branch of the superior division of the oculomotor nerve.
短暂性创伤性孤立性神经源性上睑下垂（TTINP）是一种偶有报道的罕见病症。然而，据我们所知，几乎所有已报道的病例均继发于眶周直接创伤或手术。我们现将1例伴有眶周对冲伤的TTINP病例报告如下。
一名49岁女性在行走时滑倒摔伤。她因中度头痛入院，精神状态未受影响。患者回忆受力点在枕部。入院时体格检查及计算机断层扫描（CT）显示右侧孤立性上睑下垂，双侧额叶皮质轻度挫伤和裂伤。进一步影像学检查除右侧眶内侧壁上部骨折外无其他明显异常。她接受了保守治疗，两个月后完全康复。
TTINP可能表现为一种独特的病症，对视神经动眼神经终末支造成相对轻微、可逆且无严重破坏的损伤，可能无需特殊治疗。推测其机制为动眼神经上支终末支损伤。
