Frontal Sinuses

The frontal sinuses are a pair of air-filled cavities located in the frontal bone of the skull, just above and between the eyes. They are part of the paranasal sinus system, which helps to warm, moisten and filter the air that is inhaled. In addition, these sinuses provide resonance for the voice. The frontal sinuses also permit expansion of the upper skull, which is important for growth and brain development. Abnormalities in the frontal sinuses can lead to a variety of conditions, including infection, congestion and headaches. Treatment options include antibiotics, nasal sprays, and sometimes surgery.
