Violating the platysma layer of the neck
a. 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.
b. Penetrating neck injuries remain challenging, as there are a number of important structures in a small area and injury to any of these structures may not be readily apparent.
c. The current mortality rate in civilians with penetrating neck injuries ranges from 3-6%
d. The objects causing these injuries can be divided into stabbing instruments (eg, knives, cutting instruments, puncturing objects, impaling objects) and shooting instruments (eg, missiles, projectiles).
