The only real reason why testosterone would influence the width of the face (other than some amount of cheek bone growth) is because people with weak tongue muscles might not hold their tongue in the right place in their mouths. When you don't hold your tongue in the roof of your mouth your maxilla can falls backwards and down, giving you a long ugly face. It can also cause narrowing of the palate, in fact the intermolar width was known to be much wider in earlier humans who had tougher foods to chew.
The intermolar width was not only wider in earlier civilization but very consistent across regions and ethnic groups.
Do you have any sources on that theory about holding your tongue at the roof of your mouth? this feels awkward to me, I am used to holding it flat.
