Submandibular Injury Caused by the Close-Range Firing of a Military Blank Cartridge Shot

Abstract

Few studies have reported injuries caused by a blank cartridge shot (BCS) into the head and neck. We experienced a case of minor injury resulting from BCS (despite the close proximity). The patient was a 20-year-old male soldier who attempted suicide by firing a BCS from a K2 rifle into his mouth. He suffered from skin and soft tissue defect in the submandibular area with burns and minimal bleeding. A computed tomography scan showed subcutaneous emphysema which was suspected to be related to the projectile gas released during the firing of the BCS, and a tiny fragment without hematoma or structure injuries. We closely observed the clinical features including the occurrence of infection and functional abnormalities. The subcutaneous emphysema faded away along with the soft tissue defect. After wound management was completed on the 13th hospital day, the patient was transferred to the Department of Psychiatry without any problems.
