Because the paranasal sinuses are often captured by the 2D or 3D imaging technologies, dental professionals need to be familiar with these structures and their associated pathologies. With the increasing implementation of 3-D imaging, however, specifically cone beam computed tomography (CBCT), the paranasal sinuses need to be included in the radiologic report. The paranasal sinuses are 4 paired airspaces that border the nasal cavity. The functions of the nasal cavity and paranasal sinuses include decreasing the weight of the skull, heating and humidifying inspired air, resonance in speech, regulation of intranasal pressure, and increasing surface area for olfaction. The paranasal sinuses have also been described as crumple zones or areas that absorb the energy from trauma and protect vital structures in the skull. In this webinar, I will cover for you in an easy way the anatomy and the most common pathologies associated with the paranasal sinuses. Learn More
