He diagnoses pressure on the brain, which can be cured by a risky and expensive operation involving trephining.

But such tests would be only indicative; scar tissue is easily come by, and other trephining could produce similar X-ray shadow without disturbing the central nervous system."

Based on archeological evidence, some prehistoric practitioners in both Europe and South America used trephining, making a hole in the skull to release illness.

Elliot contributed greatly to the budding field of ophthalmology, notable of which is his design of sclerocorneal trephining, still considered by many as an innovative surgical procedure to treat chronic glaucoma.

Every strange and outre case of which he had ever heard or read came back into his mind, and long before he reached the Towers he had worked himself into a positive conviction that he would be instantly required to do a trephining at the least.

Stephen and Jacob were heartily glad of it because three of their badly injured men had taken a serious turn for the worse: in one case a leg could no longer be saved, in another a resection was imperatively necessary, and in the third trephining on a solid table was preferable to the same operation on a moving deck.

This condition is often the consequence of even the most skilful trepanning.

If neither this method nor trepanning worked, the spirit was considered too powerful to be driven out of the person.

The remains suggest a belief that trepanning could cure epileptic seizures, migraines, and mental disorders.

Sophisticated stone tools designed for skull trepanning could not equal modern medical tools or modern surgical techniques.

Trepanation/Trepanning may refer to:

And in any case Stephen's trepanning of Plaice had quite wiped out what little triumphs Higgins may have had with teeth.

"That girl, Adriaria Thistle, spoke last night (with a touch of contempt) of 'sophisticated stone tools designed for skull trepanning'," Rosa said.

The ancient trepanning of skulls which so puzzled archeologists and anthropologists was directed at getting into the brain to scratch the announcing pruritus, the Boding Itch.

One example might be attaching thin sheet metal to a wooden faceplate using woodscrews, allowing the trepanning of holes, with the tool cutting into the sacrificial faceplate material.

The collective's latest production, "The Trepanning Opera," which satirizes the American health care system, will have its debut next month at Deitch Projects' Wooster Street space.

It was midnight, and the group had just performed "The Trepanning Opera," a riff on the 1800's practice of drilling a hole in a patient's skull to relieve pressure on the brain.

A trepan, sometimes called a BTA drill bit (after the Boring and Trepanning Association), is a drill bit that cuts an annulus and leaves a center core.

BTA / STS (Boring and Trepanning Association / Single Tube System) - The cutting tool is a tube.

By contrast, there was not a hair on his face or head and his skull was a glittering whitish yellow with a deep dent at the back that might have been a wound or the scar of a trepanning.

This prologue details how, during an interment at the churchyard of the title, a skull is accidentally unearthed, which bears the marks of two crushing blows to the head and - even more disconcertingly - a small hole from a trepanning.

His 1984 volume Eccentric Lives and Peculiar Notions covered such figures as Comyns Beaumont, Edward Hine and flat-earth advocate Lady Elizabeth Blount, as well as eccentric, not to say egregious, behaviour such as self-administered trepanning.
