Fractured Nose Anatomy
To better understand nasal bone fracture, it helps to understand the anatomy of the nose.
The structure of the upper one-third of the nose is bone, while the lower two-thirds are made of cartilage. The nasal septum is a thin layer of bone that separates one side of the nose from the other.
