Although an eminent specialist has stated that he has seen no ill effects occur from removal of the middle turbinate, mucous membrane and all, there is no doubt in my mind that some harm must necessarily be occasioned to the mucous membrane of the air passages in time. It may take years, but a certain amount of dryness is to be expected when so large an amount of mucous and submucous tissues with their glandular elements is removed, not taking into account the increased space in the nose and thus more rapid admission of air to the lower air passages. When ethmoid exenteration becomes necessary, removal of the middle turbinate is advocated, mucous membrane and all, as I do not believe proper drainage can be secured in any other way. In this paper, however, I intend to deal only with those cases in which more adequate nasal breathing is sought.
