5. Fractures of nasal bones are the most
common trauma to the face because of
the projection of nose on the face
Traumatic force
may act from the
front or side
Magnitude of force
will determine the
depth of injury
7. Due to frontal blow
Lower part of nasal bones
(thinner), easily gives way
Severe frontal blow will cause
“open-book fracture”
nasal septum is collapsed
and nasal bones splayed out
Greater force comminution
of nasal bones and even the
frontal process of maxillae
with flattening and widening
of nasal dorsum

10. ANGULAT
EDDue to lateral blow
May cause:
Unilateral depression of
nasal bone on the same
side
Fracture both nasal bones
& septum with deviation
of nasal bridge
nasal fractures are often accompanied
by injuries of nasal septum
(buckled, dislocated, or comminuted)
15. DIAGNOSIS
• Best made on physical
examination
• Xray:
– may or may not show
fracture
– Patient should not be
dismissed as having no
fracture because xrays did
not reveal it
– Should include Water’s view,
right & left lateral view and
occlusal view
16. TREATMENT
• Simple fracture with no displacement NO
TREATMENT
• Closed reduction
– Interfered by presence of oedema
– Best time is before the appearance of oedema, or
after it has subsided (usually 5-7 days)
– Difficult after 2 weeks because it heals by that time
• Open reduction (rare)
