12 lamina papyracea, 28 nasal bone , 53 nasal process of the maxilla, 46 zygomatic arch, 90 body of mandible, 87 ramus of mandible
Inferior alveolar canal (mandibular canal): May be damaged in mandible fractures
The mandibular canal, also known as the inferior alveolar canal (IAC), is located within the internal aspect of the mandible and contains the inferior alveolar nerve, artery and vein.
Example of a classic fracture and description. Unsure of reference.
Orbital Wall Fractures
Blow-out fractures in right orbit medial wall extended within related right side ethmoid roof and orbit floor with orbital fat and medial rectus muscle entrapment with intraconal and extraconal and eyelids preseptal emphysema are seen. Note also submucosal hemorrhage in right side maxillary and ethmoid sinuses.
Lateral orbital wall blow-in fracture and concomitant orbital floor and maxillary sinus wall fracture
The lateral orbital wall fracture is usually comminuted and associated with maxillary sinus wall fracture which leads to deformity of the face in turn. The shortening of the lateral orbital wall and inwardly displaced fractured bone can lead to dysfunctional eyelids and lateral rectus muscledysfunction respectively
Orbital floor fracture with displacement of orbital fat and inferior rectus muscle into the maxillary sinus. The globe is intact.
Although the inferior rectus muscle is displaced into the maxillary sinus "entrapment" of the muscle is assessed clinically.
Superior orbital roof blowout fracture with intact orbital rim
Isolated superior orbital roof blowout fracture with an intact orbital rim. The superior orbital roof is elevated with an acute conal/extraconal hematoma involving the superior rectus/levator palpebrae superioris muscles and contusion of the orbital gyrus of the right frontal lobe. Marked periorbital soft tissue hematoma and a minimally displaced right nasal bone is also noted.
