Final answer:
A vertical incision 4 cm lateral to the midline of the abdomen is a paramedian incision. In contrast, an oblique incision is made at an angle to the midline, a Pfannenstiel incision is a low transverse incision made just above the pubic bone, and a McBurney incision is an oblique incision made in the right lower quadrant of the abdomen.
Step-by-step explanation:
A vertical incision 4 cm lateral to the midline of the abdomen is a paramedian incision. A paramedian incision is a surgical incision made parallel to the midline of the abdomen, but not exactly at the midline.
In contrast, an oblique incision is made at an angle to the midline, a Pfannenstiel incision is a low transverse incision made just above the pubic bone, and a McBurney incision is an oblique incision made in the right lower quadrant of the abdomen.
