The term presentation describes the leading part of the fetus or the anatomical structure closest to the maternal pelvic inlet during labor. The presentation can roughly be divided into the following classifications: cephalic, breech, shoulder, and compound. Cephalic presentation is the most common and can be further subclassified as vertex, sinciput, brow, face, and chin.

Delivery, Face Presentation, and Brow Presentation ...
During childbirth, the position of the baby plays a significant role in the delivery process. While the most common fetal presentation is the head-down position (vertex presentation), variations can occur, such as face presentation and brow presentation.
What Is Brow Presentation? What Are Its Complications?
Compared to the brow presentation, face first position has a higher chance to undergo a vaginal birth, provided, the chin of the baby is near the pubic bone. But if the baby's chin is near the tailbone, C-section is the only option to avoid any complications in the delivery.
Fetal Presentation, Position, and Lie (Including Breech Presentation
Toward the end of pregnancy, the fetus moves into position for delivery. Normally, the presentation is vertex (head first), and the position is occiput anterior (facing toward the pregnant patient's spine) with the face and body angled to one side and the neck flexed. Abnormal presentations include face, brow, breech, and shoulder.
Face and brow presentations in labor
The vast majority of fetuses at term are in cephalic presentation. Approximately 5 percent of these fetuses are in a cephalic malpresentation, such as occiput posterior or transverse, face ( figure 1A-B ), or brow ( figure 2) [ 1 ]. Diagnosis and management of face and brow presentations will be reviewed here.
What is brow presentation?
Brow presentation is a rare complication, which affects only one in every 500 to one in every 1,400 births. So the chances of it happening are low. If a brow presentation is picked up in early labour, your baby may still flex her head in time for the birth. Alternatively, she may tip her head further back and be born face first.

For brow presentations, approximately 30-40% of brow ...

7.10.1 Diagnosis. 7.10.2 Management. Foetus alive. Foetus dead. Brow presentation constitutes an absolute foeto-pelvic disproportion, and vaginal delivery is impossible (except with preterm birth or extremely low birth weight). This is an obstetric emergency, because labour is obstructed and there is a risk of uterine rupture and foetal distress.
Delivery, Face and Brow Presentation
In brow presentation, the neck is not extended as much as in face presentation, and the leading part is the area between the anterior fontanelle and the orbital ridges. Brow presentation is considered the rarest of all malpresentation with a prevalence of 1 in 500 to 1 in 4000 deliveries.
Brow presentation
Pertinent etiologic factors encountered in a series of 156 patients with brow presentation, representing an incidence of 1 in 670 deliveries, include cephalopelvic disproportion and prematurity only. The brow prolongs the deceleration phase and the second stage and exaggerates the deleterious effects that other pertinent factors exert on the course of labor.

The new paradigm is that babies match the space available. Face and brow presentations occur when baby's spine extended until the head is shifted back so baby's face comes through the pelvis first. Baby may settle in a face or brow presentation before labor or they may become a face or brow presentation, usually when a posterior baby has it ...
Face and Brow Presentation: Overview, Background, Mechanism of Labor
Brow presentation is the least common of all fetal presentations and the incidence varies from 1 in 500 deliveries to 1 in 1400 deliveries. Brow presentation may be encountered early in labor but is usually a transitional state and converts to a vertex presentation after the fetal neck flexes.
Brow and face presentations

Brow presentation might obstruct vaginal births from occurring as there is less space for the baby to drop down towards the pelvic girdle.

If not, labour might be hindered, causing stress for both, the mother and the ...
Management of malposition and malpresentation in labour
