At present, autologous costal cartilage is widely used in domestic ear reconstruction body costal cartilage, while Korean hospitals mostly use artificial bone, so is it better to use autologous costal cartilage or Mantebo artificial bone? Today I will give you a detailed analysis.
First, compare the advantages and disadvantages of costal cartilage ear building and artificial bone ear building!
Advantages and disadvantages of costal cartilage ear reconstruction:
Benefits: 1 It is easy to carve and will not repel the body
2. The appearance of ears is very clear, realistic and natural

Disadvantages: 1. The costal cartilage will be more painful and more likely to leave scars.
2. The rib material itself has a certain absorption rate, and ear atrophy may occur later
3. The costectomies were over 7 years old, 1.2m tall, and weighed about 20kg before surgery, because the amount and hardness of ribs met the surgical requirements at this stage.
4. Long operation cycle
The advantages of medpor artificial bone ear reconstruction are:
1. The pain and scar of rib removal are eliminated.
2. The artificial stent is actually a polyethylene material with strong anti infection ability, high stability and strong plasticity.
3. Generally, children over 4 years old and weighing 18-20kg can be operated on together with the ear canal, and the ear can be formed with only one operation.
4. The operation cycle is relatively short.

Of course, there are also disadvantages: artificial supports are easy to slide and expose.

The absorption of costal cartilage has always been controversial. In fact, in general, only a small amount of autologous costal cartilage is absorbed. The reason why there is slight absorption is that when a doctor cuts with a scalpel, the cells in the tissue will be damaged, so there will be some absorption.
This small amount of absorption will not have a great impact on the shape of the ear. On the contrary, it will make the appearance of the ear thinner, just to make up for the thick defects of most reconstructed ears. This absorption will make the ear thinner and more natural.

Other external large absorption only occurs in the case of blood circulation disorder caused by trauma, infection and skin necrosis, but the possibility of this situation is very low.
Therefore, as far as the current medical technology is concerned, costal cartilage is still a better choice for ear reconstruction surgery.
