What is the surgical approach for zone 2 neck injuries?

1. Medial sternotomy

2. Neck exploration

3. Left thoracotomy

4. Anterior cervical discectomy

The correct answer is: Neck exploration

The surgical approach for zone 2 neck injuries is neck exploration, which is necessary to assess and manage injuries to the vascular, nervous, and aerodigestive structures located in this area. Zone 2 of the neck is defined as the region between the angle of the mandible and the superior border of the clavicle. Injuries in this zone often involve significant structures such as the common carotid artery, internal jugular vein, and various cranial nerves. Neck exploration allows for direct visualization and repair of any vascular injuries, examination of the trachea and esophagus for possible damage, and the ability to address any other potential injury within that zone. This surgical approach is favored, especially in cases of penetrating trauma, where there is a high risk of vascular and soft tissue injury. Other options such as medial sternotomy, left thoracotomy, and anterior cervical discectomy are not appropriate for managing injuries specifically confined to zone 2. These procedures target different anatomical areas or conditions and would not allow for adequate evaluation or intervention in the critical structures found in the zone 2 neck region.
