Medical results/report

Can someone help me make sense of these results? What am I looking at here?

Attached is the audiogram, which shows normal hearing thresholds. The right tympanogram is Type AB. On the left, the tympanogram is normal, and the Eustace tube function looks fine too.

Now, if someone could explain what "AB" on the right actually means, I’d appreciate it. I just found an "AD" result, and looking at the chart, that seems more likely. But even then, I don't know what that implies—does an AD reading mean I'm headed for surgery or what?

Eustace's tube is part of the middle ear, you know. So why on earth would anyone even consider surgery? AB's positions are... what, exactly?

If those are just AB positions, I don't see why surgery is necessary. Why go under the knife for that?

Did your doctor even give you a straight answer?

"Type Ad tympanogram – this occurs when the peak of the curve exceeds normal values. Essentially, the middle ear structures are overly mobile, showing high compliance with low impedance. This typically happens when the eardrum is extra flexible or perhaps thinned out due to atrophy, or sometimes because of an issue with how the ossicles are aligned, even though middle ear pressure remains normal."
