Fig. 1B. —70-year-old female cadaver with fracture of medial wall and floor of left maxillary sinus (arrows) and fracture of frontal sinus (arrowhead). Coronal multiplanar reformations (slice thickness, 1 mm; overlap, 0.5 mm) obtained from 4 x 1 mm collimation with 120 mAs show clear evidence of fractures in ultra-high-resolution mode (A) and no fracture reliably visible in non–ultra-high-resolution mode (B).
