All scans were performed<br />on 128 slice Multidetector Computed tomography (MDCT) scanner.0.5mm reconstructed<br />images in bone window and 3mm images in soft tissue window<br />were viewed on 5.1 vitrea workstation in axial, coronal and sagittal planes.<br />The CT studies were correlated with clinical examination findings, surgical and<br />histopathology. Basic radiologic patterns of cholesteatoma described on CT<br />scan were assessed. The data was processed using Microsoft excel 2007.<br />Results: Cholesteatoma was present in 48 (61%) cases. The disease was bilateral<br />in 7 cases (14 %), 39 (81 %) were unilateral. 25(52%) were left sided and<br />14 (29%) right-sided. 24 (30 %) patients were characterized as having otomastoiditis<br />whereas 7(8%) patients were radiologically difficult to characterize if<br />they were cholesteatoma or not.<br />Conclusion: Cholesteatomas can cause bone erosions and should be detected<br />early. The important role of MDCT lies in the early detection of cholesteatoma,<br />and more conservative surgical procedures can be used to eradicate<br />the disease. ER -
