Summary
Although rare, nonvertex cephalic presentations can present to labor and delivery at any gestation. It is important to be able to describe and understand the mechanics as well as risks to these malpresentations in order to be able to counsel patients and decrease maternal and neonatal complications. There are significant differences in the fetal skull diameters and with persistent brow presentation there is a risk of fetal trauma or hypoxic injury. Persistent mentum posterior and brow presentations require cesarean delivery. Informed consent should be obtained, and parents should be aware of the risks of fetal compromise based on malpresentation. Given the natural mechanics of labor, some patients remain great candidates for vaginal birth. However, in certain scenarios, patients will warrant surgical intervention with cesarean delivery.
