In our case, do we have a true orbital emphysema ?
Yes, it’s a true orbital emphysema (in fact orbital palpebral emphysema), with presence of the air in both sides of the orbital septum.
Is it an intraconal orbital emphysema ?
No, it’s an extraconal orbital emphysema, because the air is limited out of medial and lateral rectus muscles.
Fracture of the left medial orbital wall, a small herniation of orbital fat through the fracture, and orbital emphysema. Incidental fluid level with mucosal thickening of the left maxillary sinus (probably chronic sinusitis).
