Asynclitism
Definition
An abnormal position or structural deviation of the fetal head during labor, characterized by the sagittal suture not being equidistant between the maternal pubic symphysis and the sacral promontory; oblique engagement of the fetal cranium in the pelvic inlet. This anatomical precision phenomenon can complicate natural delivery, requiring careful clinical monitoring to prevent labor dystocia.
