Vertex

In the vertex cephalic presentation, the most common presentation overall, the fetus is in a longitudinal lie with an attitude of complete flexion. The parietal bones (between the two fontanels) are the presenting part of the fetus. This presentation is considered optimal for fetal descent through the pelvis.

Brow

In brow presentation, the fetus's brow or forehead is the presenting part. The fetus is in a longitudinal lie and exhibits an attitude of moderate flexion. Although this isn't the optimal presentation for a fetus, few suffer serious complications from the delivery. In fact, many brow presentations convert to vertex presentations during descent through the pelvis.

Face

The face type of cephalic presentation is unfavorable for the mother and the fetus. In this presentation, the fetus is in a longitudinal lie and exhibits an attitude of partial extension. Because the face is the presenting part of the fetal head, severe edema and facial distortion may occur from the pressure of uterine contractions during labor.

Classifying fetal presentation

Fetal presentation may be broadly classified as cephalic, shoulder, compound, or breech. Almost all births are cephalic presentations. Breech births are the second most common type.

Cephalic

In the cephalic, or head-down, presentation, the position of the fetus may be further classified by the presenting skull landmark, such as vertex, brow, sinciput, or mentum (chin).
