An asynclitic birth or asynclitism are terms used in obstetrics to refer to childbirth in which there is malposition of the head of the fetus in the uterus , relative to the birth canal. Many babies enter the pelvis in an asynclitic presentation, and most asynclitism corrects spontaneously as part of the normal birthing process. Fetal head asynclitism may affect the progression of labor, increase the need for obstetrical intervention, and may be associated with difficult instrumental delivery. When the self-correction does not occur, obstetrical intervention is necessary to deliver the child. Persistence of asynclitism can cause problems with dystocia , and has often been associated with cesarean births. However, with a skilled midwife or obstetrician a complication-free vaginal birth can sometimes, though not necessarily, be achieved through movement and positioning of the birthing person, and patience and extra time to allow for movement of the baby through the pelvis and moulding of the skull during the birthing process if this is safe in the circumstances. Other options include the use of vacuum-assisted delivery and forceps.

Asynclitism meaning

Asynclitism is defined as the "oblique malpresentation of the fetal head in labor". Asynclitism is a clinical diagnosis that may be difficult to make; it may be found during vaginal examination. It is significant because it may cause failure of progress operative or cesarean delivery. We reviewed all literature for asynclitism by performing an extensive electronic search of studies from to All studies were first reviewed by a single author and discussed with co-authors. The following studies were identified: 8 book chapters, 14 studies on asynclitism alone and 10 papers on both fetal occiput posterior position and asynclitism. The fetal head in a laboring patient may be associated with some degree of asynclitism; this is seen as usual way of the fetal head to adjust to maternal pelvic diameters. However, marked asynclitism is often detected in presence of a co-existing fetal head malposition, especially the transverse and occipital posterior positions. Digital diagnosis of asynclitism is enhanced by intrapartum ultrasound with transabdominal or transperineal approach. The accurate diagnosis of asynclitism, in an objective way, may provide a better assessment of the fetal head position that will help in the correct application of vacuum and forceps, allowing the prevention of unnecessary cesarean deliveries.

Asynclitism, the most feared malposition of the fetal head during labor, still represents to date an unresolved field of interest, remaining one of the most common causes of prolonged or obstructed labor, dystocia, assisted delivery, and cesarean section. Traditionally asynclitism is diagnosed by vaginal examination, which is, however, burdened by a high grade of bias. On the contrary, the recent scientific evidence highly suggests the use of intrapartum ultrasonography, which would be more accurate and reliable when compared to the vaginal examination for malposition assessment.

If your doctor has medically cleared you, try some light exercises that you can safely do at home to help position your baby optimally for birth. Asynclitism is most easily diagnosed during labor when the cervix is opened allowing the orientation of the occiput , the back of the fetal head, to be visually assessed in relation to the mother's pelvis.
