Saddle nose, commonly known as collapsed nose bridge, is a kind of deformity with lower nose bridge than normal and sunken nose back in different degrees, which is mostly caused by trauma, infection and congenital malformation. The basic principle of rhinoplasty is to fill the collapsed part of the nose with materials to raise the bridge of the nose to a suitable height, so as to obtain an ideal nose shape.

Judging from the development of nose, it is best to carry out saddle nose cosmetic surgery after puberty, that is, after 17 years old, because the development of nasal bone and cartilage has been basically finalized at this time, and there will not be much change after operation. Cosmetic plastic surgery is called nose augmentation surgery.

Saddle nose can be divided into simple type and complex type, and can be divided into three degrees according to its degree:

Mild: slight collapse of nasal bone, slightly flat and wide nasal dorsum, slightly concave or unnatural curvature.

Moderate: the bridge of the nose is obviously collapsed, the root of the nose is wide, the nostrils are facing the sky, the nose tip and alar are small and flat, and the nose length is short.

Severe: the back of the nose is severely depressed, the bridge of the nose is not obvious, and it is accompanied by bony structure of the external nose, nasal septum and nasal mucosa deformity.

Most people who do rhinoplasty are mild to moderate saddle noses.
