摘要
the lateral cephalogram is an x-ray routinely used in orthodontics. this type of plane x-ray is the best choice to investigate the morphometric characteristics of the sella turcica, its size and shape, creating a variation. taveras %26 wood described a method to determine the size of the sella in radiography. measuring the diameter of the anterior sella turcica and the depth of it from the lowest point to a line connecting the top of the back of the sella to the sellar tuber. this led to a study of the present characteristics , which reported observations in 88 lateral teleradiograph takes, of which 44 were young adult mapuche individuals and 44 non mapuche of both sexes, all native to the ix region. the anteroposterior diameter of the sella turcica was 12.85 ㊣ 1.5mm, ranging from 10.05 to 15.95 mm, the depth was 10.31 ㊣ 1.3 mm, with ranges of 7.20 to 13.36 mm, in mapuche individuals anteroposterior diameter was 12.11 ㊣ 2.4 mm, ranging from 6.72 to 17.06 mm, the depth was 11.01 ㊣ 1.4 mm, ranging from 7.92 to 13.67mm. sellar area in mapuches has been set at 132.4 mm2 and non mapuche of 133.3 mm2. the shape of the fossa of the sella turcica was circular in 36 cases, oval in 30 cases and plane in 22 cases.
