There are both transverse and longitudinal incisions for cesarean section, which are chosen according to the specific situation of the mother. 1. Transverse incision: Compared with longitudinal incision, transverse incision is more beautiful and the bleeding is relatively reduced, but it is more demanding for the operator, if the suture is not good, it will easily lead to poor healing of the uterus. In addition, the field of vision is smaller in transverse incision, which is not easy to operate. 2. Longitudinal incision: The longitudinal incision is larger and not as beautiful as the transverse incision. However, it is faster to enter the abdomen, shorter operation time, and more adequate exposure of the surgical field. It is suitable for women with placenta praevia or those who are predicted to need uterine resection or removal of large fibroids during the operation. It is recommended that women who choose cesarean section choose the incision method according to their own situation under the guidance of the doctor. If there is an indication for longitudinal incision, the transverse incision should not be chosen for the sake of aesthetic appearance of the incision, in order to avoid prolonging the surgical process and endangering the life of the fetus.
