What Is the Perichondrium?

The perichondrium is a layer of connective tissue found in human and animal cartilage and bones. Its main role is protection, such as protecting bone growth and supporting cartilage development. This type of organization also plays a role in maintaining blood flow. The periosteum is dense, but porous and flexible, so it promotes blood flow and oxygen transport. Infants and young children have the highest density of this connective tissue around the bones, but there is a large amount of perichonium around the cartilage of all ages. The nose and ears [auditory organs] are some of the areas where such tissues are abundant. They help keep these areas strong by assisting in nutrient transmission and preventing damage. It also plays a key role in cell regeneration when wounded.

The main functions of the perichondrium

As with most connective tissue, the main function of the perichondrium is to provide elasticity and protection to more sensitive or vulnerable parts of the body. It is essentially a thin film, made up of many proteins linked together, and houses highly concentrated blood vessels. These blood vessels transfer nutrients between the cartilage and help the cartilage stay strong. It is one of the many layers of the human body. Although it cannot work alone, it plays a very important role.

This type of tissue membrane is found throughout the body, but is most dense in cartilage structures such as the nose and ears. Other parts of the body that contain this type of tissue include the throat trachea and where the ribs and sternum are connected. The tissue layer also protects critical parts of the back, and this layer of cells can be found between the vertebrae of the spine.

It covers many smaller bone-connecting surfaces, works with other layers of cells to promote joint resistance, and reduces friction when moving. However, there is no perichonium on the body's longest bones because the bone overlay is not its primary function.

The clinical effect of perichondrial cartilage in tympanoplasty

Since Heermann first started to use the palisade cartilage technique to repair the large perforation of the tympanic membrane, the application of cartilage technique in middle ear surgery has now been widely recognized. Jia Huan et al proposed that the cartilage has a certain hardness, which can maintain a fixed shape and is easier to place during surgery; secondly, it can resist the negative pressure of the middle ear and maintain a good shape; The chance of reperforation is low.
