Nasal sinus

Stylized paranasal sinus cavities shown within a simplified facial bone or skull cross-section as hollow rounded to slightly irregular air-filled chambers with smooth inner walls. Pale beige bone outlines surround pale open or lightly translucent lumens, and the sinus lining may be indicated as a thin pink mucosal layer along the inner surface.
