Are very frequent, can be isolated or associated with other cranial fractures.
Are composed and decomposed, the first do not require treatment, can affect the nasal bones and/or the septum.
Can be classified into side and front trauma fractures.
In those side can be affected by trauma 3 plans as a function of increasing kinetic:
I floor: ipsilateral nasal bones with evident sinking;
II floor: nasal septum and nasal bones contralateral;
III floor: fracture of the frontal process of the maxilla and lacrimal bone with possible fragmentation and damage lacrimal apparatus.
Also in frontal trauma are recognized 3 floors:
I floor: Tip of the nose, often with avulsion of superior cartilages;
II floor: nasal plug, back and septum, with crushing of the pyramid and septal deviation;
III floor: extended to the orbit or the cranial bones.
Particular forms of fractures: open book, sights, to green wood (typical of children), comminuted fractures
The nondisplaced fracture of the nasal bones are in most cases a problem exclusively aesthetic and only rarely can affect the nasal breathing. And’ still need a specialist rating to exclude hematomas of the nasal septum and to evaluate the best treatment.
And’ nasal fractures can be reduced to try to realign the fractured segments. The procedure is commonly performed in surgery sedation
