How long does tissue necrosis take after a high‑pressure pinpoint entry of a foreign body?

• A. 1-2 Hours
• B. 4-12 Hours
• C. 24-48 Hours
• D. 3-6 Hours

Answer: (B)

High‑pressure entry injuries cause rapid damage beyond what the external wound suggests. The force drives material into tissues and crushes small vessels, leading to immediate vascular compromise and a cascade of ischemic injury. Because blood flow to the affected area is quickly impaired, tissue death tends to become evident within hours rather than days. The typical window for the onset of necrosis in these injuries is about four to twelve hours after the incident, though progression can continue if not addressed promptly. This is why urgent assessment and early surgical management are emphasized for high‑pressure injections—the goal is to relieve the ischemia and remove nonviable tissue before extensive necrosis develops.
