Q

(Orbital Apex Fractures) “Indirect traumatic optic neuropathy” usually results from

(STTB)

A
  • Stretching
  • Tearing

Q

________: roof fractures are more common

A

Young children

7
Q

Roof fractures in young children are more common because

A
  1. Frontal sinus has not yet pneumatized (increase in volume)
  2. The ratio of cranial vault to the midface is greater than in adult
8
