Diagnostic value of axial view high resolution computerized tomography of temporal bone of tympanosclerosis

Objective By analyzing axial view HRCT of temporal bone to approach the diagnostic value to tympanosclerosis.Methods 20 axial view HRCT of temporal bone of tympanosclerosis confirmed by operation were analyzed.Results The soft tissue masses within tympanic cavity were found in 6 ears,both soft tissue masses and calcification in 13 ears.Calcification only in tympanic membranes was found in 1 ear.16 ears were showing tympanic membrane thickening.Tympanosclerosis plaque that embraced auditory ossicles was found in 19 ears.Round windows were involved in 2 ears.Conclusions Axial view HRCT of temporal bone can demonstrate tympanosclerosis plaque in tympanic membranes and within tympanic cavity which may contribute to diagnosis of tympanosclerosis.
