Is this dangerous?

I’ve had this discharge for years that smells awful (maybe around 3 years) and it’s constantly itching. I went to an ENT several months ago and he didn’t mention it could be this and my pcp recently hasn’t seen anything either.

Could it still be a cholesteatoma? If so is it super dangerous if I’ve had it for a few years? I heard it can spread to the brain which scares me because I have bad health anxiety.
