Fig. 3

Comparison of temporal bone CT images between the two groups (abnormal mastoid development). Note: As can be seen from the above figure, the temporal bone CT findings in the healthy control group revealed a predominantly hollow mastoid, with numerous transparent, clear, and well-spaced air cells arranged in a honeycomb pattern. The temporal bone CT findings of the MS group revealed a dense, sclerotic, and thick mastoid without visible air cells. These temporal bone CT findings in the MS group are indicative of abnormal mastoid development. Blue arrows indicate the location of vestibular organs and red arrows indicate the location of various structural abnormalities
