In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

The fetal head then continues descent into the pelvis, below the pubic arch and out through the vaginal opening. This is assisted by the additional maternal efforts of pushing, or bearing down, similar to defecation. The appearance of the fetal head at the vaginal opening is termed crowning. At this point, the mother will feel an intense ...
Caput succedaneum is a benign neonatal condition involving a serosanguinous (containing blood and serum), subcutaneous, extra-periosteal fluid collection with poorly defined margins caused by the pressure on the presenting part of the fetal scalp by the vaginal walls and uterus as the infant passes through a narrowed cervix during delivery.
From that point, pressure from the presenting part (head in vertex births or bottom in breech births), along with uterine contractions, will dilate the cervix to 10 centimeters, which is "complete." Cervical dilation is accompanied by effacement, the thinning of the cervix. General guidelines for cervical dilation: Latent phase: 0–3 centimeters
In some extreme cases, this could cause temporary or permanent facial nerve injury. Furthermore, if the forceps' handler were to twist his or her wrist while the grip was on the baby's head, this would twist the baby's neck and cause damage to a cranial nerve, resulting in strabismus. In rare cases, a clavicle fracture to the baby could occur.
A chignon (an artificially induced caput succedaneum) is a temporary swelling caused by a build-up of bloody fluid left on an infant's head after they have been delivered by vacuum extraction. A vacuum extraction is a type of assistance used during vaginal delivery by an obstetrician or midwife when the second stage of labor, where the cervix ...
