Which presentation is best for a smooth delivery of the baby?
Many types of presentations are possible right before childbirth. The most common is a cephalic presentation, head-first, facing down, with the baby’s chin tucked in.
Is occiput transverse position normal?
Although the position is common before labor begins, most OT fetuses spontaneously rotate during labor as the fetus descends and deliver in the occiput anterior (OA), or less commonly the occiput posterior (OP), position.
What causes Occipito posterior position?
The occipitoposterior position in the main is caused by the adaptation of the head to a pelvis having a narrow fore pelvis and an ample anteroposterior diameter and therefore may be considered “physiologic.”
How common is occiput posterior baby?
Background. Occiput posterior position is the most common malpresentation in labour, contributes to about 18% of emergency caesarean sections and is associated with a high risk of assisted delivery.
How do I know if my baby is occiput anterior or posterior?
This is called the occipito-anterior position. It allows them to move more easily through the pelvis. If your baby is head down (cephalic) but facing your tummy (their back to your back), this is called the occipito-posterior position. If your baby is legs and bottom down, this is called the ‘breech’ position.
Can you give birth if baby is posterior?
Unfortunately, approximately five in 100 babies remain in the posterior position during labor. A woman can safely give birth to a baby in the posterior position, but labor may be longer and more painful. The risk of complications is also much greater.
Can you go into labor with transverse baby?
Delivering a Transverse Baby It is almost impossible to deliver a transverse baby vaginally. So if a baby is still lying sideways at term or when labor begins, a C-section (caesarean) may be the safest option for delivering the baby.
What is the most common fetal position?
Right or Left Occiput Anterior The left occiput anterior (LOA) position is the most common in labor. In this position, the baby’s head is slightly off-center in the pelvis with the back of the head toward the mother’s left thigh.
What is occiput transverse position?
Occiput transverse (OT) position is a type of fetal cephalic malposition in which the sagittal suture and fontanels align 0 to <15 degrees from the transverse plane of the maternal pelvis ( figure 1 ).
What is posterior occiput presentation?
Posterior Occiput Presentation (Concept Id: C0856256) A fetal position during delivery in which the head of the fetus is facing the mother’s abdomen. Posterior Occiput Presentation MedGen UID: 452765 •Concept ID: C0856256 Finding Definition A fetal position during delivery in which the head of the fetus is facing the mother’s abdomen.
Do babies in occiput posterior position require emergency cesarean birth?
Babies in occiput posterior position are significantly more likely to require an emergency cesarean birth compared with babies in occiput transverse position in the second stage of labor: A prospective observational study.

What is the diagnostic feature for OT position?
The key diagnostic feature for identification of OT position is the location of the fetal orbits. Both orbits are posterior when the fetus is occiput anterior (OA) and both are anterior when the fetus is occiput posterior (OP), whereas in OT position, one orbit is anterior and the other is posterior.
