Sٍtudy of Mastoid Air Cells Diseases using Spiral CT

Abstract

This study was aimed to study mastoid air cells diseases and their complications using spiral CT. It was conducted in Alfaisal Specialized hospital and Ibn Elhaitham Diagnostic center in the period from September 2012 to January 2013. Hundered patients of different ages and different genders whom suspected of having mastoid air cells pathologies underwent Spiral CT scan of their temporal bones using 4MDSCT (Toshiba medical system), the scanning was done with collimation of (1-2) mm, 2mm slice thickens,120 Kvp, 160 mA and 1 second rotation time. The results were confirmed that the mastoid air cells diseases were very common and they had serious complications; the diseases of mastoditis and mastoditis with CSOM had higher frequency 83 %, and they had pathological changes of anatomical structures of the temporal bones which contains organs of hearing and balance. Finally the study finding revealed that Spiral CT scan was an effective imaging modality in studying of mastoid air cells diseases and their complications. Also it was more effective to explain the complex anatomical structures of the temporal bones and hence the pathological changes within it.
