title: Hyperaeration of the frontal sinus.
abstract: The nasal cavity and paranasal sinuses constitute an anatomical and functional unit. Paranasal sinuses communicate with the nasal cavities, which are covered by the same mucosa, via small openings and narrow ducts that allow both aeration and sinus drainage. Anatomical variations of the paranasal sinuses and nasal cavity are important in sinus diseases. Computerized tomography (CT) plays a critical role in evaluation of the patients with paranasal sinus pathology and variations. A 38-year-old man admitted to our clinic with headache and postnasal dripping for 1 year. His paranasal CT scanning revealed that there is hyperaeration of the frontal sinus which is in continuity with the sphenoid sinus. Hyperaeration of the sinuses may be kept in mind in a patient complaining of headache.
