Did you try "trepanation"?
The alternative spelling "autotrepanation" is a lot more popular. Er, I think I missed the point. You can delete this now.
I didn't know about that spelling. My dictionary definitely says "trephination" is the correct spelling (of the main word).
The far more interesting question here is, why would anyone want to drill a hole in their own skull?
Some people, and indeed some ancient customs, believed that drilling holes in your head would deform the skull structure, and thus allows the brain to grow bigger and becomes more intelligent. This theory was even used once in an episode of "The X-Files".
I think your dictionary is wrong. The tool is definitely a trepan, I have this on good authority from a neurosurgeon in training.
"(Auto)trephanation" and "(auto)trepanation" seem to be slight variants of the same thing. My American Heritage Dictionary refers to the trephine as the surgical instrument and trepan as an alternate form of that term. Webster's Encyclopedia Unabridged Dictionary clarifies further, asserting that the trepan is "an obsolete form of the trephine". So maybe autotrepanation is what folks used to do in, say, medieval times, while autotrephination would apply to one who performed this strange act today using modern medical instruments? Heh.
According to my copy of Concise Oxford, a trepan is the implement and a trephine is an improved form of a trepan - with guiding centre-pin!

That puts my Case Mods to shame!
Wow! I thought I had seen everything. That is one of the most disturbing things I have ever seen.
And here I was thinking Dremels were only good for cutting aluminium!
When you only got 1 result did you add it to Googlewhack?
No because googlewhack requires two dictionary words.
There are nine now, mostly descended from Joel's comment.
Joel, I think you forgot about this movie: http://www.imdb.com/title/tt0099611/ Even though I haven't seen it personally, my wife tells me it has autotrephination galore.

I need this like I need a hole in my head.
