Asynclitism

Asynclitism is an inclination of the fetal skull towards the shoulder, resulting in the top of its skull either approaching the sacrum (anterior asynclitism, or Naegsle asynclitism), or to the pubic bone (posterior asynclitism, or Litzmann asynclitism). In this case, the fetal head cannot pass freely through the mother's pelvis during childbirth.

Asynclitism is one of the conditions that can occur during the birth process. Under normal conditions, the fetal head must be correctly oriented in the maternal pelvis to pass through its narrow canals. However, in the case of asynclitism, the fetal head tilts towards the shoulder or pubic bone, creating an abnormal position.

Anterior asynclitism occurs when the top of the fetal skull approaches the mother's sacrum. This may occur due to incorrect orientation of the fetal head or due to abnormalities in the shape of the mother's pelvic bones. Posterior asynclitism occurs when the top of the fetal skull approaches the mother's pubic bone. This condition can be caused by a variety of factors, including the shape and size of the pelvis and the position and movement of the fetus.

Asynclitism can create difficulties during childbirth. A tilted fetal head can make it difficult for the mother to pass through the birth canal and cause prolonged and difficult labor. In such cases, medical intervention, such as the use of obstetric instruments or a caesarean section, may be required to ensure safe delivery of the fetus.

The diagnosis of asynclitism can be made during intravaginal examination during labor. The doctor assesses the position of the fetal head and determines the presence of asynclitism. If asynclitism is detected, medical personnel can take appropriate measures to facilitate the birth process.

Preventing asynclitism can be challenging as most cases are due to maternal and fetal anatomy. However, regular check-ups during pregnancy and timely consultation with a doctor if problems arise can help identify asynclitism in advance and take appropriate measures.

In conclusion, asynclitism is a condition in which the tilting of the fetal head creates an obstruction to passage through the mother's birth canal. This can cause difficulties and increase the risk of complications during childbirth. Regular medical monitoring and timely intervention may be necessary to ensure safe delivery of the fetus.

Asynclitism is a clinical sign when the baby's head in the womb is located below the chin. This usually indicates that the fetus is abnormally positioned and will not be able to pass through the birth canal without complications.

The tilt of the fetal skull can occur both to the right and to the left. Most often, it is the types of posterior asynclitosis that occur. That is, first the child appears outside the uterus, the baby’s head turns to the side and only then the arms and legs do the rest; less and less energy is spent on their appearance. However, sometimes, if the head is not too low, the baby simply sits in the stomach - he is already ready to emerge, but is held there by the big toe.

Why is this happening? Here are some reasons that lead to a
