Frontal Sinuses

Definition

The frontal sinuses are air-filled spaces located within the frontal bone of the skull, just above the eyebrows. They are part of the paranasal sinus system and play a role in the overall functioning of the respiratory system.

5 Must Know Facts For Your Next Test

1. The frontal sinuses develop during childhood and continue to grow in size until adulthood.
2. They are connected to the nasal cavity through the frontonasal duct, allowing air to flow between the sinuses and the nose.
3. The frontal sinuses help to lighten the weight of the skull and contribute to the resonance of the voice.
4. Inflammation or infection of the frontal sinuses, known as frontal sinusitis, can cause pain, headaches, and other symptoms.
5. The size and shape of the frontal sinuses can vary greatly between individuals, and they are often used in forensic identification.
