Objective: The purpose of our work is to define the relationship between severity of hearing loss caused by chronic cholesteatomatous otitis media, and reported data of clinical, paraclinical, surgical exploration findings.

Patients and Methods: This is a retrospective, descriptive and analytical study, performed at the ENT Department at August 20, Casablanca University Hospital, involving 100 cases of patients operated for chronic otitis media of cholesteatoma.

Results: The age of our patients ranged between 6 and 91 years with an average of 29.95 years and a peak between 10 and 20 years. Both sexes presented an equal percentage. Otological antecedents were found in 29% of our patients. The most common symptoms revealing are purulent otorrhea (46.34%) and hearing loss (32.68%). The patients with tympanic perforation presented the highest losses with an average of 61.9 dB and an average Rinne of 34.9 dB. The dominant type of hearing loss, in the audiogram, was transmission deafness (68 cases) with an average loss of 50.3 dB and an average Rinne of 33 dB. The lesions sought by CT scan, such as ossicular lysis, mastoid filling, meso tympanic and antro attical filling, presented loss and Rinne with approximate values. The several surgical techniques and ossiculoplasty represent the main means of auditory rehabilitation.
During the surgical exploration the mastoid localization presented the most important losses with an average of 78.33 dB and an average Rinne of 35.83 dB, the other searched features presented approximate values.

Conclusion: Hearing loss, which is a common way of Cholesteatoma revelation, should be systematically explored and properly treated by using different surgical techniques and prostheses when needed.
