A persistent tale in martial arts is that one can strike an unfortunate other on the nose in such a way that you drive the cartilege up into their brain. Is this possible?
I think some points to consider are:
- Is there a path from the inside of the nose to the brain that doesn't pass through bone?
- If not, could the cartilege penetrate any intervening bone?
- Is the cartilege in the nose long enough to reach into the brain before the hand propelling it stops against rim of the nasal cavity?
- Is the cartilege attached to the skull in such a way that a blow could send it into the skull?
The reasons I doubt the claim are that:
- I've never heard of a boxer suffering this injury, despite millions of fights and training sessions containing billions of punches having occured.
- I've taken an upward travelling kick to the face that broke my nose, and the cartilege just stuck out the side! :-)
