An undiscovered nasal bone fracture in childhood.
Most of the saddle nose or aquiline nose deformities of teenagers are caused by nose fractures that were not found in childhood. The child's bridge of the nose structure is not fully developed, plus ignorance and hyperactivity, which is not easy to find after injury and delays treatment.
Fetal congenital malformation
If the fetal head grows too large and the space in the uterus is narrow, pressure will be generated, which will cause the nose to be squeezed in the uterus, resulting in congenital deformities such as nasal bone displacement and crooked nose. Some fetuses are also subjected to excessive pressure from the mother's pelvis during childbirth, resulting in a flat or curved nose.
Growth characteristics of nose
The development of children's nose changes with age more obviously than most other organs. After birth and infancy, the shape of the nose is usually wide, the middle is curved and concave, the tip of the nose is upward, and the nose grows rapidly. About 7 years old, the length of the nose is about twice as long as that at birth and about three times as long as that of 14 years old. It is precisely because of this growth characteristic of the nose that the real nose deformity is not easy to detect in childhood.
Timing of treatment
How old can a child do rhinoplasty? It is generally believed that the most suitable time for rhinoplasty is when the nasal bone is fully grown. Women are about 16~ 17 years old, and men are about 18~20 years old.
