It is most common for individuals working in hazardous environments to sustain soft tissue injuries to the head, face, and neck.  On the battlefield, the structures that regulate the senses (eyes, ears, and nose) are extremely important for survival.  The delicate structures, such as the eye, demand the health-care provider be diligent in the care of injured and damaged sensory organs.  Also, when soft tissue injuries are present, underlying structures such as the cranium, brain, trachea, neck vessels, and cervical spine may also be damage.
