Double top diameter more than 10 can be delivered

The fetal biparietal diameter refers to the widest distance between the tops of the two sides of the fetus, that is, the transverse diameter. Generally, the fetal biparietal diameter is between 9.0 and 9.6 cm, more than 9.6 cm. This biparietal diameter is relatively large. Then the biparietal diameter exceeds 10, indicating that the fetal head is relatively large. The transverse diameter is relatively wide, and the head circumference is relatively large. If the pure biparietal diameter of the fetus is 10, excluding hydrocephalus and abnormal brain, then the fetal head is too large, and the height and abdominal circumference are in the normal range. If the mother is tall, the fetal position is normal, the pelvis is wide, and the uterine opening can be scheduled after labor, and the fetal head can normally decline. Under these circumstances, then there is still the possibility of normal labor. However, if the biparietal diameter exceeds 10, it is relatively large, the pelvis is not spacious enough, or the position is abnormal, and the labor force is not good, then it is possible that the cephalic position is difficult to produce, and it is difficult for him to successfully deliver through the vagina. Therefore, if the biparietal diameter exceeds 10, it can be determined after the specific obstetrician evaluates the labor.
