Positional Deformity of the Jaw

photo by Janelle Aby, MD

In this newborn, the gums are not parallel with each other. This is due to in utero molding, when the head has been turned to one side (to the right in this baby) and the chin has been pushed up against the shoulder for some time. The angle is usually mild, but in some cases, it can be pronounced enough that the jaw subluxes with opening. Spontaneous resolution is expected.
