General Considerations.—Sewell130 states that there are two ways of surgically curing diseased sinuses: "obliteration" and "elimination." The former is accomplished by removal of the bony walls and their lining mucosa, which is replaced by other tissue, as may be the case in certain frontal and ethmoid procedures. By "elimination" he refers to the procedure by means of which a sinus is made incapable of retaining secretions, as would be the case with the sphenoid operation he devised, whereby the floor is completely removed. The author admits that whereas obliteration of the ethmoid sinuses is the result of the external operation, that is not advisable in the case of the frontal sinus and therefore it is necessary to provide for adequate drainage into the nose, which is possible only through thorough exenteration of the ethmoid sinuses. As for the Caldwell-Luc operation, he has seen numerous failures, despite
