Did You Know?
PERIOP BRIEFING
DID YOU KNOW? History of craniotomy instruments. Evidence of craniotomy procedures dates back to the neolithic period (8000 to 5000 B.C.), and experts postulate that these procedures were performed as part of spiritual or religious rituals.1 Before metallic instruments were introduced, craniotomy instruments consisted of pointed cutting tools of silica or obsidian that were used to make either progressively deeper circular incisions in the bone or a series of small burr holes that could be connected by breaking the bone between them to remove a section of the cranium. In the 16th century, surgeons used mobile drills with interchangeable burrs and drill bits, similar to the modern instruments used today.
