Removal of iatrogenic orbital foreign bodies with a 3D model.

Facial foreign body (FB) is common after trauma, but iatrogenic orbital FB is a rare and unexpected complication of facial FB removal surgery. We present the case of a 43-year-old man with a glass FB in his nose. During the operation, this FB broke into two pieces, and the larger one pierced into the left orbit, close to the eyeball. A three-dimensional (3D) model was made that accurately recreated the shape and position of the FB in the orbit, according to which the FB was removed. 3D-printing technology is a great tool when dealing with complex facial FB.
