![]() ![]() ![]() Where: Location of both the injury and number of wound sites (suspected entry and exit wounds), as well as their nearness to vital structures. This should include responses to the following considerations: Obtain essential information about the mechanism of injury, is vital. The most important part of the evaluation is a careful and thorough physical examination. The posterior triangle contains muscles, the spinal accessory nerve, and the spinal column. The anterior triangle contains most of the major anatomic structures of the neck including the larynx, trachea, pharynx, esophagus, and major vascular structures. The sternocleidomastoid muscle separates the neck into two triangles. Since it is very close to the base of the skull, this area is less amenable to physical examination and difficult to explore during surgical evaluation.Īnatomically, the neck is also described in triangles. This area contains the distal carotid and vertebral arteries and the pharynx. ![]() Zone III: This is the area between the angle of the mandible and the base of the skull. It is the largest zone and the most commonly injured in the neck. This zone has comparatively easy access for clinical examination and surgical exploration. The following structures are located here: the carotid and vertebral arteries, the internal jugular veins, the trachea, and the esophagus. Zone II: This is the area between the cricoid cartilage and the angle of the mandible. Furthermore, surgical exposure and access can be difficult in this zone, because of the presence of the clavicle and bony structures of the thoracic inlet. This zone contains vital structures which include the innominate vessels, the origin of the common carotid artery, the subclavian vessels and the vertebral artery, the brachial plexus, the trachea, the esophagus, the apex of the lung, and the thoracic duct. Zone 1: This is the area between the clavicles and the cricoid cartilage. Understanding the anatomy of the neck, especially the location of important structures, is essential to providing optimal care. Since the zone system is helpful in guiding management decisions, it is preferable to employ the zone system when describing traumatic injuries. In penetrating trauma, zone designations have anatomic, diagnostic, and management implications. įor descriptive and clinical management purposes, the neck is divided into three zones: zones 1, 2, and 3. These structures may pose a diagnostic and therapeutic dilemma in the emergency department. The management of neck trauma can be challenging and sometimes overwhelming, as this anatomical region contains many vital structures. ![]()
