抄録

<p>　　As linear orbital floor fractures often entrap the inferior rectus muscle and soft tissue into the fracture line, emergency restoration is recommended to treat the oculocardiac reflex and avoid ocular movement disorder due to inferior rectus muscle necrosis/contracture.<BR>　　We report a case in which a foreign body granuloma occurred late in the lower eyelid after emergency repair of linear orbital floor fracture.<BR>　　A 7-year-old girl presented to our hospital with left facial pain/headache, nausea, and vomiting. Left eye upward ocular movement disorder was observed. Computed tomography and magnetic resonance imaging revealed a left orbital floor linear fracture with deviation/deformation of the inferior rectus muscle due to soft tissue entrapment. Emergency surgery was performed 9 hours after injury, and the upward ocular movement improved and there was no persistent diplopia. One year and 4 months later, redness, swelling, and entropion of the lower left eyelid developed. A foreign body granuloma of the lower eyelid was found strongly adhering to the palpebral conjunctiva and orbicularis oculi muscle. After granuloma excision, the lower eyelid entropion improved promptly.<BR>　　Emergency restoration surgery requires additional careful and delicate manipulation for immediate management of the injured eyelid.</p>
