When postoperative PTA-ABG [less than or equal to]10 dB was used to define successful hearing outcomes, the significantly favorable predictive factors were S0 pathological status of the stapes (p=0.0425) and development of mastoid cells
with MC2-3 (better developed mastoid cells
In preoperative CT scans of the patient, some soft tissue density and aeration loss was observed in mastoid cells
, but as our initial diagnosis was chronic otitis media and we did not observe any signs of cholesteatoma in the middle ear cavity and attic region after clearance of the polypoid mass, we did not explore the mastoid region.
A CT scan, performed two days later, showed right side mastoid cells
filled with liquid and thickening of mucosa.
In more severe cases, hyperpneumatization of equilateral mastoid cells
and elevation of a petrous ridge and orbital roof can be seen .
