Searching for info on csf in ear that causes hearing loss

I am now 3 months post-op MVD, and still don’t have my hearing back. I was told it would come back in 3 months by my NS, but my ENT says it won’t. I still haven’t lost hope that my hearing will come back. I would like to understand more about how csf gets in the ear during MVD, how it re absorbs, is there any way to find out if I have fluid or if my hearing loss is permanent? I would greatly appreciate any info!! I want my hearing back!!

Thank you!

I lost hearing after my MVD and I have been trying to find out information on it myself. Mine was in 2008. When I had another one in 2012, the surgeon said, the nerves were drooping by my ear. (or something like that) I never had a csf leak in either one.
