Where are your sinuses located?

The sinuses are air-filled cavities located within the bones of the face and skull. They are primarily found in four main areas: the frontal sinuses (in the forehead), maxillary sinuses (in the cheeks), ethmoid sinuses (between the eyes), and sphenoid sinuses (behind the eyes). These cavities help to lighten the skull, produce mucus, and contribute to vocal resonance.
