Fracture of the Nasal Bone
- Most common facial bone fracture (40% of facial bone fractures)
- Usually from direct blow during athletics, motor vehicle collision or an altercation; sometimes fall
- Males more common
- There may be associated fractures of the anterior maxillary spine, blow-out fractures of the orbit or fractures of the nasal septum
Normal anatomy of the nasal bones
- Deformity of the nose
- Nasal fractures may not be evident on plain films
- One suture line should normally be visible at the nasofrontal suture
- Otherwise, there should be no lucencies that traverse the nasal bones perpendicular to its long axis
- There may be lucencies that are normally seen that traverse the nasal bones longitudinally
- CT provides the best means of identifying facial fractures
- Nasal packing
- Closed reduction
- Surgical reduction
