3D computed tomography (CT) head scan showing the upper airway, paranasal sinuses (behind the nose), and ear structure from the side. The paranasal sinuses are a group of four paired air-filled spaces within the facial bones surrounding the nasal cavity. Suggested functions include immunity, reducing head weight, humidifying inspired (breathed-in) air and increasing vocal resonance. | |
