Abstract: An instrument devised by the author for measurement of auricular head height and its use are reported. For the comparative evaluation of this method (the new method) with the modification of the direct method described by Martin (the old method), the author and two other measurers took measurement of the auricular head height in a series of 78 students with the old method and with the new method, and obtained the following results: 1) The difference between the maximum and minimum values determined on the individual subjects by three measurers independently averages 5.45mm.(σ=3.10) with the old method and 2.62 mm.(σ=1.78) with the new method. 2) The difference between the trained measurer and the two untrained measurers, respectively, averages 3.06 mm.(σ=2.48)and 4.32 mm.(σ=3.16) with the old method, and 1.59 mm.(σ=1.46)and 1.49 mm.(σ=1.31) with the new method.
