Summary
| Description |
English: CASE E.-SPHENOCEPHALUS.
W. N. (Low-Grade Imbecile). A Mexican peon, aged 35 years. He was a good workman under direction. The stigmata of degeneration are marked. Note that he is an excellent example of sphenocephalus, or wedge-shaped head, which is the result of synostotis of the sagittal suture with compensatory growth in the region of the large fontanelle. Note also the protrusion of the frontal bones, the naso-bragmatic arc, which is very marked; the wide cranio-facial angle; and the opistho- gnathism, which, although not extremely excessive, is worthy of note. The attachment of the ear is normal, but the ear itself is very defective. The lobule is V-shaped and adherent; the antitragus is absent; and the antihelix is very much enlarged, so that the scaphoid fossa and the fossa triangularis, cymba fossa, and cavum concha are unusually deep. |
