Impacted cerumen and conductive hearing loss

Hey. Im actually a speech pathology student but need a bit of help with an audiology case study.
A client has a bilateral, mild, low frequency conductive hearing loss,consistent with impacted cerumen found on her otoscopic examination.
After this has been treated the client still has a bilateral, mild, low frequency conductive hearing loss .
So i guess my question is to what degree can impacted cerumen affect hearing and with the condition treated, would her hearing levels (dB) drop towards normal limits by what degree? 10? eg. 35dB at 250Hz to 25dB at 250Hz?
I have had some trouble finding literature regarding the degree, understanding that is generally a case by case thing.

Impacted cerumen are reported to create negligible amount of conductive hearing loss (<=10 dB) in approximately 20% of patients, 11-20 dB of hearing loss in approximately 50% of patients, and 21-30 dB of hearing loss in 30% of patients (Subha & Raman, 2006).
