Dislocation of the cartilage or fracture of the nasal bones that makes the bridge of the nose. A blow from the side can knock the cartilage or bones out of position or cause displacement of the nasal septum (the dividing partition inside the nose). A frontal blow tends to splay the bones of the nose outwards, depressing the bridge. The fracture is often accompanied by an extreme swelling of overlying soft tissue. A fractured nose is excruciating and remains tender for about three weeks after the injury.
Resetting is often undergone immediately after the injury, before the swelling has started, or after the swelling has gone down. Sometimes, a displaced bridge can be carefully manipulated into position under a local anaesthetic. However, a general aneathesetic is mostly required. A plaster splint is occasionally needed during healing.
