case_images: No other abnormalities were found, apart from a retention cyst in the right maxillary sinus (Figures 1-4). Tatlisumak et al.. The width, height, and anteroposterior length of each frontal sinus and the total width of both sinuses were calculated (Figures 1 and 2).
case_images: (a) Linear measurements of frontal sinus in the axial plane (RL: anteroposterior length of the right sinus and LL: anteroposterior length of the left sinus). (b) Area calculation of the sphenoid sinuses and the mastoid air cells in the axial plane.

case_images: No other abnormalities were found, apart from a retention cyst in the right maxillary sinus (Figures 1-4). Tatlisumak et al.. The width, height, and anteroposterior length of each frontal sinus and the total width of both sinuses were calculated (Figures 1 and 2). The area of each sinus was measured in every axial CT image (Figure 2) and multiplied by the slice thickness.
case_images: (a) The frontal sinus enchroaching the orbit. (b) The optic nerves are exposed (arrows) in the superior part of the sphenoid sinus.

case_images: No other abnormalities were found, apart from a retention cyst in the right maxillary sinus (Figures 1-4).
case_images: The frontal lobe looks smaller in size due to the enlargement of the frontal sinus. Linear measurements of maxillary sinus (RW: width of the right sinus, LW: width of the left sinus, RH: height of the right sinus, and LH: height of the left sinus).
