No, cholesteatoma infection ruins middle ear's bones structure. Same level of hearing can never be recovered. I had bilateral chronic otitis media & cholesteatoma with pearl cavity in ears, even though my left ear made recovery from the chronic otitis media & cholesteatoma + psychologically painful tinnitus, & the surgeon did made artificial bones structure from left ear's external side's cartilage bone but it did little improve the hearing loss (from 60DCB < 55DCB). My right ear still suffering from intermittent otitis if by any chance single drop of water infiltrates inside right ear.
