Retracted Eardrum, Any Solution / Treatment?

Hi,

It turns out that due to tinnitus produced by acoustic trauma, I have the tympanies retracted.
Such is the "retraction", that when I try to do the Valsalva maneuver I have to do it, with a lot of intensity, and I am not able to expand the tympanies, or if I am able only very little and only in the left tympani.

I have been looking for information in this forum, about if there is any possible treatment, but I have not found anything.
Do you know something about it?

I think that if the ear retraction can be improved, consequently I can improve my tinnitus.

Thanks and best regards
