The nasal bone (Latin translation: Os nasal) is duplicated in humans; both parts ossify in the course of life. Together, the two nasal bones form the nasal cavity. The front part, however, consists of cartilage, which connects to the front of the respective nasal bone. This reduces the risk of the nose breaking.
On the inside of the nasal bone is the nasal septum (Nasal septum), which divides the nasal cavity into two cavities of roughly the same size.
Each nasal cavity is in turn divided into a nasal vestibule (Vestibulum nasi) and the actual nasal cavity (Cavitas nasi).

Forced force from the front (e.g. blow, impact, etc.) breaks both nasal bones, whereby the cartilaginous part and the nasal septum are often also involved.
The patient is usually in pain and there is also a nosebleed. If the broken bone parts are shifted against each other, the nose is deformed (deviation to the side, indentation). In addition, swelling can occur due to the formation of a hematoma.

A broken nose can usually be diagnosed without an X-ray; just by feeling and looking at the nose. Nevertheless, an x-ray of the facial skull is recommended to rule out further bone fractures.
If the fragments are not displaced, the nasal bone will heal itself back together. If the fragments are displaced or the bridge of the nose is deformed or the nasal septum deviates, this should be treated surgically. This then has to be temporarily fixed with a splint.
If the nasal bone fracture leads to heavy nosebleeds, which does not end by itself, a nasal packing should also be inserted. This would compress the vessels so that the bleeding stops.
A septal hematoma (nasal septum hematoma) can also occur if the septum is involved. This is a bleeding between the bone / cartilage and the bone or cartilage skin, which can lead to a complete obstruction of nasal breathing. In addition, the cartilage / bone can deteriorate, as the blood supply is guaranteed via the bone or cartilage skin.
If this is lifted, the cartilage / bones no longer reach nutrients and it can die. A nasal septum hematoma must therefore always be opened surgically and the coagulated blood clots removed so that the bone or cartilage skin can be reassembled.

There is a Indentation of the bridge of the nose.
This deformity can be congenital, including in Trisomy 21 or at one Syphilis infection during pregnancy. But also through Fractures or at Tumors on the nose A change in the nasal bone can lead to a saddle nose. Sometimes those affected also have impaired nasal breathing. The saddle nose can be corrected surgically (Rhinoplasty).
A crooked nose is often caused by a Fracture of the nasal bone and is usually only discovered when the initial swelling of the nasal fracture has subsided. Uneven growth in childhood can also lead to a crooked nose. Also the Nasal septum is crooked, which hinders nasal breathing. Then it can be corrected surgically.
The hump nose is characterized by a hump on the bridge of the nose and a tip of the nose that is bent downwards.
These too Deformity of the nose has various causes and can be corrected by plastic surgery.
With the tension nose, the nasal septum is too long in relation to the bridge of the nose and thus pulls the tip of the nose downwards. Often these patients suffer from one restricted nasal breathing through too small nostrils. This can also be corrected surgically.
