The frontal sinus is one of the paranasal sinuses. Anteriorly, the frontal sinuses are contained by the forehead and the superciliary arches; superiorly and posteriorly by the anterior cranial fossa and inferiorly by the bony orbit, the anterior ethmoidal sinuses and the nasal cavity. Medially the sinuses face one another, and are separated by the midline. This pair of sinuses are irregular in shape when compared to one another and is underdeveloped at birth. They reach their full size and shape around seven to eight years of age. They drain primarily into the ethmoidal infundibulum and the corresponding lymph drainage occurs via the submandibular lymph nodes. It is innervated by the ophthalmic nerve, including the supraorbital and supratrochlear branches. In the full version of this video tutorial, we will be discussing the following points: overview and definition of paranasal sinuses and, specifically, the frontal sinus; Then we are going to look at the structures that can be seen at the level of the frontal sinus on a cross section: skull bones and joints; lobes of the brain, sulci and gyri; muscles seen at this level; and finally we will look at the blood vessels found at this level.
