n. a surgical procedure in which a disk of bone is removed from the skull with a circular instrument (a trephine) having a sawlike edge. On the basis of evidence found in skulls of Neolithic humans, trephining is believed to be one of the oldest types of surgery.

What is trephining Why was it used?

By Galen’s time (129–199) trephining was in standard use in treating skull fracture for relieving pressure, for gaining access to remove skull fragments that threatened the dura, and, as in Hippocratic medicine, for drainage.

Is trephining still used?

Trepanation is still used today, often to treat bleeding on the brain. However, making a permanent hole in someone’s head isn’t a safe thing to do, and these days if a doctor makes a hole in a skull they usually replace the bone and patch it up.

Why would you need a craniectomy?

A craniectomy is a surgery done to remove a part of your skull in order to relieve pressure in that area when your brain swells. A craniectomy is usually performed after a traumatic brain injury. It’s also done to treat conditions that cause your brain to swell or bleed.

When did trephining stop?

The treatment was largely practiced until the early 16th century. An article in the journal World Neurosurgery reported that trepanation was widely practiced throughout China thousands of years ago.

When was trephining used?

The oldest discovered skulls showing evidence of trepanation date back to the Mesolithic period — around 6000 B.C. They emerged in North Africa, Ukraine, and Portugal. Share on Pinterest Trepanation seems to have begun in the Stone Age.

Does skull grow back after surgery?

Conclusions: This case report shows that cranial bone regeneration is possible in children older than 6 years old, bypassing the need for cranioplasty after decompressive craniectomy.

What is the difference between craniotomy and craniectomy?

A Craniectomy is similar to a craniotomy as both procedures involve removing a portion of the skull, the difference is that after a craniotomy the bone is replaced and after a craniectomy the bone is not immediately replaced.

What is a craniectomy defect?

A craniectomy is a common neurosurgical procedure in which a portion of the skull is resected, but not put back (cf. craniotomy in which the bone flap is re-attached to the surgical defect) 1. The defect is usually covered over with a skin flap.

How long is a craniectomy?

Depending on the underlying problem being treated, the surgery can take 3 to 5 hours or longer.

How common was trepanning?

More than 1,500 trephined skulls from the Neolithic period (representing 5 to 10% of all Stone Age skulls) have been uncovered throughout the world – from Europe, Siberia, China and the Americas.

Can you survive trepanation?

As a tendency, the survival rate appears to be relatively high from the Neolithic to Late Antiquity but then decreases until Pre-Modern times. The 78% survival rate in Late Iron Age Switzerland indicates that the surgery was often performed successfully.

Can you live with a hole in your skull?

“Physical damage to one part may be fatal, but in another it may have very little effect.” Rose adds: “If the lower regions of the brain or spinal cord are damaged – regions that control heart rate, breathing etc – the consequences are likely to be fatal.
