Cranial gravitational bullet injuries and human and material losses apply to those falling bullets and their effect when they struck the cranium of human being and their consequence and material loss. Our aims were to study the importance of craniocerebral falling-bullet injuries, the clinical and computed tomography scan criteria, events that are associated with bullet firing, treatment options, and outcome of these injuries. Reviewing literatures: we search all the available literature from 1990 to October 2017 in PubMed, Google Scholar, and ResearchGate with the following key words: gravitational bullets injury, tangential wound, penetrating wound, ricochet, careening, and falling-bullet hear injury. The wounds caused by gravitational projectiles are a relevant problem in many countries of the world. The problem caused by this type of elements must be addressed from the prevention.
