Considerable confusion exists in rhinology, and always has, concerning the classification of minor cells in the frontal area. These cavities have been variously termed "ethmofrontal cells," "anterior ethmoid cells" and "the frontal group of the ethmoid labyrinth." They have also on occasion been designated "duplicate" or "supernumerary" frontal sinuses. Certainly from a genetic and from a topographic standpoint the latter terms are well applied.

Davis¹ in his work on the development of the nasal sinuses reported supernumerary sinuses in 7 of 202 specimens. His observations also indicate that the frontal sinus is not always the earlier tenant of the frontal bone. A cell which causes a bulge in the floor of the sinus (frontal bulla) arrives at its mature position ahead of the sinus, which grows around it. Corroborative evidence of this may be found in certain adult specimens, those in which a cell is present in the posterior medial . . . [Full Text PDF of this Article]
