(a) Computed tomography showing a high-density shadow running through the nasal bone. (b) Computed tomography after operation at the district hospital showing two high-density shadows. One is located in the nasal cavity, and the other in the left orbit

Computed tomography (CT) of the paranasal sinuses was performed at a district hospital, which showed a strip of dense shadow transversely running through the nasal bone, measuring 25 mm x 5 mm [Fig. 1a]. Postoperative CT showed that the glass FB broke into two pieces: the larger one pierced into the left orbit close to the eye and the rest remained in the nasal cavity [Fig. 1b].

Three-dimensional (3D) model preparation: Based on the patient's CT data, a 3D model was made at a scale of 1:1 that accurately recreated the shape and position of the FB in the left orbit [Fig. 2a]. Then, the orbital septum was opened, and the intraorbital FB was carefully removed [Fig. 2b].

The surrounding tissues of the nasal FB were fully separated, and the FB was carefully removed [Fig. 3a]. Postoperative CT demonstrated complete removal of the intranasal and intraorbital FBs [Fig. 3b].
