Figures 10, 11 and 12 illustrate the different stages of excessive and arrested development of the helix. For the purpose of giving a better description of the stigmata of the ear I have divided the ear into upper, middle and lower third. Figure 10 shows arrest of the helix as far up as the upper third, while the upper part is well developed. Figure 11 shows the helix normally developed. Figure 12 illustrates the lower third normally developed, while the upper middle and upper third are excessively developed.
When the whole or a large part of the helix is arrested the ear is usually (not always) larger and the antihelix is excessively developed. On the other hand, when the whole helix or larger part is excessively developed the ear is usually (not always) small and thick, with arrested antihelix. When the ear is at or near an angle of 90
