Firearm/bullet wounds in the skull

Wound of entrance shows a punched in (clean) hole in the outer table. Cone shaped bone is detached from the inner table forming a crater that is larger than the hole of the outer table and shows beveling (sloping surface).

Fissured fractures are seen radiating from the defect.

Irregular lacerations may be seen involving the leptomeninges.

Pieces of bone from the wound of entry are often driven into the cranial cavity and may establish the bullet track.

At the point of exit a punched out opening is produced in the inner table and beveled opening in the outer table.

The wound is funnel shaped with the funnel opening in the direction in which the bullet is travelling both in entrance and exit wound.

The exit wound is larger due to deformity and tumbling of the bullet after entering the skull.


Q. 9

Bullet entry wound, for bullet entering at acute angle is identified by what shape of abrasion collar ‑

 A

Circular

 B

Rectangular

 C

Oval

 D

None of the above

Q. 9

Bullet entry wound, for bullet entering at acute angle is identified by what shape of abrasion collar ‑

 A

Circular

 B

Rectangular

 C

Oval

 D

None of the above

Ans. C

Explanation:

Ans. is `c’ i.e., Oval

If bullet enters at acute angle to the skin then the abrasion collar is oval and if the bullet enters at right angle to the skin the abrasion collar is circular.

The image shown is of a contact wound type of Firearm injury.

Gunshot injury/Firearm Wounds

  • Entrance wounds
    • Firearm entrance wounds are typically round to oval, with smooth edges and a zone of epidermal abrasion surrounding the wound edge.
    • Surrounding skin dragged in
  • Categorized based on range
    • Contact Wounds:
      • Muzzle is pressed against the skin when fired
      • Impression of muzzle burned around entrance
      • When the muzzle of a firearm is held firmly against the skin of a victim as it is fired, a hard contact wound results. In this wound, a dark zone of soot (carbon) deposition is present around the edge of the entrance wound.This soot is seared into the skin by hot gases exiting the firearm muzzle and cannot be completely washed away from the wound. It may also be possible to discern a cherry red color of the underlying soft tissues due to the carboxyhemoglobin formed when carbon monoxide that is formed from the burning powder charge is injected into the tissues with the muzzle blast.
      • In areas of “loose” skin (abdomen, chest): circular wound with blackened, seared skin margins
      • On head, where the scalp is tightly covering the skull, entry wounds can have several different appearances:
      • Round wound with blackened, seared skin margins
      • Stellate shaped wound, due to tearing of skin from expanding gas dissecting between the scalp and skull
    • Near contact(6-8 inches): muzzle of the gun is held a short distance from the skin (< 1 cm from skin with handguns)
      • Appears as circular wound with blackened and seared edges that are wider than seen with contact wounds.
      • Soot may be deposited loosely on the skin, it may be largely washed away during cleaning of blood from the wound.
    • Intermediate((1-3 feets)): defined by the presence of stippling (“powder tattooing”) on the skin surrounding the entry wound
      • Stippling is due to unburned powder grains exiting from the gun causing pinpoint abrasions on the skin; these are not burns
    • Distant(more than 3 feets): No soot or burning of wound margins
      • Appear as round wounds with sharp margins and an abrasion ring on the surrounding skin
  • Exit wound:
    • Skin punched out.
    • Exit wounds are usually irregular, have no abrasion rim, and do not display soot deposition or stippling.
