Your main sinuses are air‑filled spaces in the bones of your face and skull, clustered around your nose and eyes.

Quick Scoop: Where your sinuses are

When people say “your sinuses,” they usually mean the paranasal sinuses — four paired cavities that connect to your nasal passages.

  • Maxillary sinuses – in your cheek area, one on each side of your nose, just below your eyes and behind the cheekbones.
  • Frontal sinuses – in your forehead, above the bridge of your nose and roughly behind your eyebrows.
  • Ethmoid sinuses – a cluster of small air cells between your eyes, right behind the bridge of your nose.
  • Sphenoid sinuses – deeper in the skull, behind the nose and eyes, roughly in the center of your head.

Put simply: if you draw a “T” across your forehead and down the bridge of your nose into your cheeks, most of that zone covers where your sinuses sit.
