pneumatization of mastoid air cells. In this study, the effect of NSD on pneumatization of mastoid cells and the relationship between NSD and chronic otitis media were investigated using CT scan.<br> <strong>METHODS:</strong> In this cross-sectional study, 75 paranasal sinus CT scans with NSD and mastoid view were investigated. Patients were divided into three groups based on the severity of NSD: mild (deviation less than 9 degrees, 25 patients), moderate (deviation from 9 to 15 degrees, 25 patients) and severe (deviation equal to or greater than 15 degrees, 25 patients). Chronic otitis media is defined as the presence of bone destruction or sclerosis accompanied by mass fluid or structural changes in temporal bone air cells.
