Orbitoethmoid metallic foreign body

Abstract

Intraorbital foreign body extending to sinuses is rare; often such cases are associated with multiple ocular and orbital morbidities. Retained organic foreign bodies can cause severe inflammation and are detected earlier, whereas inorganic foreign bodies are inert and well tolerated except copper. The management of posteriorly located orbital foreign bodies is a therapeutic dilemma. We report an unusual case of posterior orbital foreign body extending to the ethmoids and sphenoid sinus exclusively removed by transnasal endoscopic approach. Transnasal endoscopic approach can be used as an effective and efficient approach for the removal of orbital foreign bodies lodged on the medial side of the orbit. This approach is recommended in all the cases of foreign bodies in the craniofacial region provided that it is approachable through endoscope and expertise and facilities are available.
