Expressing the area of free air space as a proportion (percentage) of the total cross-sectional area of the nasal cavity results in a convenient whole number index on a continuous scale that is positively related to the degree of atrophy of the nasal conchae. The snouts from each group were evaluated by three different methods, visual snout scoring and two morphometric methods: the first based on TAR and the second based on a modification of TAR (MTAR) devised by the authors.\n Morphometric values were derived from three tracings on each snout photograph ( Fig 1 ) of: the rectangle created by tangential lines to the external contours of the left and right turbinates (P); the irregular shapes resulting from the outline of the snout's turbinates (formed by the nasal ear fringe), where M is the sum of these areas; and the irregular shapes resulting from the outline of air spaces in each nostril (generated by the fringe ear nasal cavities), where S is the sum of these areas.
