Abstract:
Primary pneumatization of the frontal bone occurs in the first year of life, but further pneumatization continues until 18 years of age. Elongation of the ethmoidal infundibulum and frontal recess, or upwards migration of the anterior ethmoidal cells has been proposed as a mechanism of frontal sinus development. The frontal sinus drainage pathway is displaced in the anterior or posterior direction depending on the pneumatization pattern of the frontoethmoidal cells. Also, frontal sinuses can be connected to the infundibulum or directly to the middle meatus depending on the superior attachment pattern of the uncinate process. Bilateral frontal sinuses are separated by their bony septum, and thus have their own drainage pathways. Contrary to this general rule, we experienced two cases of frontal sinuses that were connected to each other, showing a single drainage pathway from both frontal sinuses. We report these two cases along with a literature review.
