Have you checked ammonia, nitrite, and pH. I've seen something like this on my Weather Loaches and turned out my pH was low. Mine had what looked like white patches that started peeling. Looked like sunburned skin.

Water parameters are all normal. I think it may be Columnaris. Im finding alot of conflicting info on how to treat it.

It looks like a post-injury infection to me. Your substrate looks as if may have some sharp edges to it so that is a possible source. Just my best guess at a glance.

i have seen older cory cats with hole in the head...if its been going on for some time (months) then it may be that. if its new, then post injury infection. columnaris isnt usually on the face like that, and cory cats dont seem to get it as much, so i would guess a bacterial infection. Try any of the common antibacterial medicines...move him to a smaller tank so you dont have to treat the entire tank, and can save money on meds.
