Differences in mastoid and middle-ear cavity opacification in CT between intensive care patients and patients with acute mastoiditis requiring surgical treatment.

The extend of middle-ear cavity opacification revealed highly significant differences Applying a 5 level Likert-scale approach to describe the extent of middle-ear cavity opacification we could show significant differences in the case-control cohorts (LR, Pe = 0.022, 0.039, Fig. 4 A) and a simple yes/no scoring revealed even a higher level of significance (LR, Pe = 0.013, 0.016, Fig. 4 B).
