# of NASAL BONES & SEPTUM
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
Types of Nasal Fractures
depressed angulated
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 dorsumDEPRE
SSED
ANGULATED Due 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)
CLINICAL FEATURES
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
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)
