Surgical incision
Encyclopedia
In surgical practice, deciding on the right type of surgical access for a specific condition would be a skill of its own for a surgeon. The decision to select a specific incision would depend on the several ascpects e.g. surgical site, related anatomical structures, easy access, less complications, quicker healing and minimum scar. But, at instances, all these options might not be fulfilled and the surgeons have to make a professional judgment as to decide on what's best for the patients' condition and act fast in order to save the life of the patient.
Incision is placed perpendicular to the spinoumblical line at Mc Burney's point, i.e. at the junction of lateral one-third and medial two-third of spino-umblical line.

Cherney incision
Cherney described a transverse incision that allows excellent surgical exposure to the space of Retzius and the pelvic sidewall. The skin and fascia are cut in a manner similar to a Maylard incision. The rectus muscles are separated to the pubis symphysis and separated from the pyramidalis muscles. A plane is developed between the fibrous tendons of the rectus muscle and the underlying transversalis fascia. Using electrocautery, the rectus tendons are cut from the pubic bone. The rectus muscles are retracted and the peritoneum opened.Chevron incision
This incision a cut is made on the abdomen below the rib cage. The cut starts under the armpit below the ribs on the right side of the abdomen and continues all the way across the abdomen to the opposite arm pit thereby the whole width of the abdomen is cut to provide access to the liver. The average length of the incision is approximately 24 to 30 inches.Gridiron's incision(Mc Burney's incision)
An oblique incision made in the right lower quadrant of the abdomen, classically used for appendectomyIncision is placed perpendicular to the spinoumblical line at Mc Burney's point, i.e. at the junction of lateral one-third and medial two-third of spino-umblical line.

McBurney incision
This is the incision used for open appendectomy, it begins 2 to 5 centimeters above the anterior superior iliac spine and continues to a point one-third of the way to the umbilicus (McBurney's point). Thus, the incision is parallel to the external oblique muscle of the abdomen which allows the muscle to be split in the direction of its fibers, decreasing healing times and scar tissue formation. This incision heals rapidly and generally has good cosmetic results, especially if a subcuticular suture is used to close the skin.Median sternotomy
This is the primary incision used for cardiac procedures. It extends from the sternal notch to the xiphoid process. The sternum is divided, and a finochietto retractor used to keep the incision open.Midline incision
The most common incision for laparotomy is the midline incision, a vertical incision which follows the linea alba.- The upper midline incision usually extends from the xiphoid processXiphoid processThe xiphoid process, or xiphisternum or metasternum, is a small cartilaginous process of the lower part of the sternum which is usually ossified in the adult human. By age 15 to 29, the xiphoid usually fuses to the body of the sternum with a fibrous joint. Unlike the synovial articulation of major...
