brow presentation, presentation in which the brow, or forehead, of the fetus is the first part of the body to enter the birth canal. Because the diameter of the fetal head at this angle may be greater than that of the mother’s pelvic outlet, a cesarean section may be recommended. However, the fetus usually converts to a vertex presentation. If not and labor is obstructed, alternatives for delivery include rotation of the fetal head using forceps or cesarean section
