A frontal section through the paranasal sinuses showing the mechanism of normal respiration on the left and signs of sinusitis on the right. This head section anatomy model by 3B Scientific presents a frontal section through the human paranasal sinuses covered with mucous membrane. The head model C13/1 / 1012789 shows normal anatomy and the mechanism of ventilation on the left side, and signs of sinusitis (paranasal sinus inflammation) on the right. The anatomy of the internal head structures are shown in a slightly simplified way in order to clearly demonstrate the ventilation routes of the frontal and maxillary sinuses. The physiological ventilation routes - emphasized with the blue arrow - are shown on the left hand side of the model. In the area of the right nasal sinuses, congested mucosa can be seen as they appear for example when the nasal sinuses are inflamed (sinusitis). When this happens, correct ventilation is prevented because of the narrowing of the passages, and the secretions are unable to drain. An ideal model for educating patients about the mechanisms of breathing and the causes and symptoms of sinusitis. Download Head Section Model with Sinusitis C13/1 / 1012789 product manual here.
