Background and Objectives：Some pathologies, such as otitis media or E-tube dysfunction, may cause sclerosis in the temporalbone, which then tends to shrink in size. The aim of this study is to evaluate morphologic changes that result from sclerosis in thetemporal bone. Subjects and Method：We measured 9 variables on 2 axial images and 7 variables on 2 coronal images in healthyears and diseased ears of 37 unilateral chronic otitis media patients. We also measured the volume of the mastoid pneumatization.Results：The mastoid volume in the sclerotic temporal bones was significantly smaller than that in the pneumatic ones. Thedistance from sigmoid sinus to Henles spine was most significantly correlated to the degree of volume reduction, and it accountedfor about 17.7% of the total variation in volume reduction. There was no difference in sigmoid sinus types between sclerotic andpneumatic mastoids. Conclusion：The sclerosis of the temporal bone reduces the volume of mastoid pneumatization. However,the large portion of volume reduction may result from the sclerotic change in the air cell system, rather than from the shrinkage ofthe mastoid bone. So, the location of surgically-important structures in the middle and inner ears is rarely changed in the sclerotictemporal bone.
