Nasal Bone

The nasal bones are two small, oblong plates that meet in the midline to form the bridge of the nose. They are the most commonly broken bones of the face — the nose's lower two-thirds are cartilage, not bone, so nasal fractures involve these small bones at the top of the nose.

Key facts

The two nasal bones form only the bridge (upper third) of the nose.
The rest of the external nose is cartilage, which is why it is flexible.
They join the frontal bone above and the maxillae at the sides.
Despite their small size they help define the face's profile.
They sit directly over the upper nasal cavity.

What can go wrong

Nasal bone fractures are among the most common facial fractures, from sport, falls and blows. Signs include swelling, bruising around the eyes and a visibly shifted nose. A collection of blood under the septum's lining is the one complication checked for urgently, as it can damage the cartilage if not drained.

Frequently asked questions

Is a broken nose a broken nasal bone?

Usually, yes — the fracture is in one or both nasal bones at the bridge. The lower nose is cartilage, which can be bent or torn but does not fracture in the same way.

Does every broken nose need resetting?

No. If the nose is straight and breathing is normal, many fractures are left to heal. A visibly crooked nose is usually assessed after the swelling settles, when it can be straightened if needed.
