What are the causes of laryngeal contusion?

summary

Blunt injury of larynx is also called closed injury of larynx. When combined with multiple trauma, such as head, chest, abdomen, etc., because of the serious condition, laryngeal contusion is easy to be ignored. Sometimes only tracheotomy can relieve the obstruction of the larynx, but not deal with the injury of the larynx in time, which leads to the formation of traumatic laryngeal stricture. What are the causes of laryngeal contusion? Let's talk about it

What are the causes of laryngeal contusion?

Larynx is not easy to be contused because of its activity and elasticity of cartilage, as well as the protection of mandible, sternum stalk, clavicle and cervical vertebra. Laryngeal contusion is common in traffic accidents, industrial injuries, sports injuries, boxing injuries and strangulation injuries.

There are many kinds of injuries in industrial trauma and earthquake trauma. Traffic accident injuries are more common, and the injury mechanism is more complex. When the car suddenly stops, the patient's head tilts back and his throat protrudes forward, and hits the hard object in the car, squeezing the laryngeal cartilage and other structures in front of the cervical vertebrae,

Because the thyroid cartilage is more prominent, it is more vulnerable to injury than cricoid cartilage. The elderly have calcification and poor elasticity of laryngeal cartilage, and are more prone to cartilage fracture than the young. If the direction of violence is low, it may lead to cricoid cartilage fracture or separation of trachea and cricoid cartilage.

matters needing attention

Laryngeal contusion in the acute stage of correct treatment, respiratory function can be restored, but the vocal function is often not ideal. Avoid the injury again, don't drink, don't eat spicy food.
