Broke a BONE? wow... As I understand it, that's not supposed to happen. Usualy, the sinus passage will simply fill with blood before a pressure imballance can get bad enough to break bone.
Worst I've done is some painfull squeezing behind the left eyebrow trying to decend (stopped diving after that on that trip) and a reverse squeeze on the second 15 foot dive of the day when I THOUGHT I was completely over a cold...
Couldn't come up shallower than 5 feet without significant pain for a while as I let it slowly equalize...
Again, the left eye, but this time it was the sinus passages all the way around the eye. Thick mucus blocked the connection back into the nasal cavity preventing the pressure release.
Felt like I had a black eye when I woke up the next day and was blowing junk out of my nose for another two weeks because of it.
Ever since I broke my nose when I was a kid, the left side always clogs up first...
