What is Zone 2 of the neck?
Zone II: This is the area between the cricoid cartilage and the angle of the mandible. The following structures are located here: the carotid and vertebral arteries, the internal jugular veins, the trachea, and the esophagus. This zone has comparatively easy access for clinical examination and surgical exploration.
What is a Zone 2 injury?
Zone II (mid-neck) – from the cricoid cartilage to the angle of the mandible: carotid/vertebral artery, larynx, trachea, esophagus, jugular vein, vagus and recurrent laryngeal nerves.
What is blunt neck trauma?
Neck trauma is usually divided into two categories, blunt and penetrating trauma. Blunt Trauma-may result in crushed larynx, tracheal disruption, expanding hematoma, esophageal leak. Penetrating trauma-may result in injury to major vascular structures, pharynx, larynx, trachea, esophagus.
How do you treat penetrating neck injury?
Cricothyotomy and tracheotomy are the two most commonly used procedures for severe neck trauma. We recommend cricothyrotomy as the first surgical airway of choice, as it is the most direct, simple and safe way of bypassing upper airway obstruction or injury.
Which part of the neck is the most vulnerable?
The upper part of your spine, beginning at the base of your skull and extending down the neck into the upper back, is known as the cervical spine. The neck is highly vulnerable during accidents, as even the most minor incident can lead to neck pain.
What are the different neck zones in penetrating neck injuries?
The neck has been divided into threes zones. Zone I, including the thoracic inlet, up to the level of the cricothyroid membrane, is treated as an upper thoracic injury. Zone III, above the angle of the mandible, is treated as a head injury. Zone II, between zones I and III, is the area of controversy.
Which neck zone is associated with the highest mortality rate when injured?
Zone I extends between the clavicles and the cricoid cartilage; injuries to this zone carry the highest mortality because of vascular injury and high-risk surgical explorations (4). Zone II is superior to Zone I and extends as far as the angle of the mandible.
Should you put pressure on a neck wound?
Control of bleeding with direct pressure on the wound site is adequate initially.
Which of the following is used to define penetrating neck injury?
Penetrating neck trauma involves a missile or sharp object penetrating the skin and violating the platysma layer of the neck. This includes gunshot wounds, stab or puncture wounds, and impalement injuries.
What are the three zones of neck injury?
The neck has been divided into threes zones. Zone I, including the thoracic inlet, up to the level of the cricothyroid membrane, is treated as an upper thoracic injury. Zone III, above the angle of the mandible, is treated as a head injury.
What is the management of a neck injury?
The management of injuries to the neck that penetrate the platysma is dependent on the anatomic level of injury. The neck has been divided into threes zones. Zone I, including the thoracic inlet, up to the level of the cricothyroid membrane, is treated as an upper thoracic injury.
What is the risk of a penetrating injury to the neck?
Risk of significant injury to vital structures in the neck is dependent on the penetrating object. For gunshot wounds, approximately 50% (higher with high velocity weapons) of victims have significant injuries, whereas this risk may be only 10% to 20% with stab wounds.
