Thin inferior wall frequently injured, requires less energy
Medial wall consists of thin lamina papyracea, requires intermediate energy
Lateral blow out fractures require higher force
Blow-out Fracture
Fracture of inferior or medial<unk>  walls with out fracture of<unk>  ridge
Adipose tissue, inferior rectus or inferior oblique can entrap within maxillary or ethmoid sinus
33% are associated with ocular trauma
Non Blow-out Fracture
Lateral, inferior, and superior<unk>  ridge fracture typically occurs with other facial fractures
Naso-orbito-ethmoid fracture
Associated with force applied to nasal bridge
Often accompanied by injury to lacrimal duct, dural tears, and traumatic brain injury
