trepanation

A surgeon performs a trepanation procedure on a patient's skull.

Definition

1. Noun:
   • Surgical procedure: "Trepanation" refers to the surgical practice of drilling or cutting a hole into the human skull, exposing the dura mater (the outermost membrane covering the brain). This procedure is typically performed to treat various medical conditions, such as relieving intracranial pressure, removing blood clots, or accessing the brain for other surgical interventions.

Usage Examples

• Noun:
  • Ancient civilizations often performed trepanation for ritualistic or therapeutic purposes. (The practice of drilling a hole in the skull was common in early societies.)
  • The neurosurgeon recommended trepanation to reduce pressure caused by a subdural hematoma. (The surgical procedure was suggested to alleviate brain swelling.)
  • Evidence of trepanation has been found in archaeological remains from prehistoric times. (Archaeologists discovered skulls with holes indicating the procedure was performed long ago.)

Advanced Usage

• "to undergo trepanation": to receive this specific surgical treatment.

  • The patient underwent trepanation to treat a severe head injury. (The person had a hole drilled in the skull as part of medical care.)

• "trepanation as a therapeutic measure": using the procedure to address health problems.

  • In modern medicine, trepanation is rarely used except as a therapeutic measure for critical conditions. (The procedure is now reserved for serious medical emergencies.)

Synonyms

• Craniotomy: a surgical procedure in which a part of the skull is removed to access the brain, though it typically involves a larger opening than trepanation.
