What types of incisions are made in the abdomen?
Vertical incisions are very rare. This is called a classical incision by lay people because it was the original type of cesarean incision used. The medical term for this type of incisions is a vertical midline. These are only used in extreme circumstances.
The horizontal or bikini incision (pfannenstiel incision) is a very common type of incision used on the abdomen. It it placed at the top of to pubic hair or just over the hair line as the c-section is started. This provides a much more cosmetically appealing scar once it is healed.
