-ectomy -ostomy -otomy, oh my!

linky

People may not do lobotomies, but people still do some crazy things to their heads.

The question is (applying newfound Cecil-knowledge) why is it “trepanation” and not “craniostomy”?

This thing sounds like Friz Freleng was the director.

Cecil also did a column on this: What’s the story on trepanation?

Correctly, it is craniostomy, as in “burr hole craniostomy.”

Of course, you have to carefully differentiate it from craniotomy.
