This was very helpful! From what I can tell this was a middle ear barotrauma with effusion, no eardrum rupture. I did have some sensorineural and conductive hearing loss. No other symptoms of inner ear injury though.
I was treated with steroids. Here is the audiologist report on 6/27 and then on 7/12. We don't have a baseline, but can assume the right ear is a good baseline for the left.

Thanks! So it looks like you had a mixed hearing loss (conductive AND sensironeural) which improved on steroids. Likely the biggest improvement was in the conductive component with some improvement in the bone line (sensorneural) in the high frequencies (hard to say 100% from the audio scan, having a bit of a problem reading all of it).
That does suggest some degree of inner ear injury, possibly transmitted injury from the middle ear barotrauma. There is no tympanogram on the affected ear on the first scan (the doctor told the audiologist not to do it?), but presumably it would have showed middle ear fluid causing the conductive hearing loss.
A CT scan might be helpful in determining if there was a bony abnormality making the inner ear more vulnerable, but a negative scan can't rule that out.
The bottom line is that this story does suggest some increased risk of further (possibly permanent) hearing loss with future injury. No doctor is going to be able to really "clear" you, ultimately you will need to make this decision by juggling unquanitifiable risks. I can't really tell you much one way or the other, but I certainly would be concerned about your diving with this history.
