The Pfannenstiel incision is a transverse skin incision, two finger-breadths above the symphysis pubis, which is extended in the direction of the anterior superior iliac spine (ASIS) and ends 2–3 cm medial to ASIS on both sides (4).
What is a Pfannenstiel incision and why is it preferred?
A Pfannenstiel incision /ˈfɑːnɪnʃtiːl/, Kerr incision, Pfannenstiel-Kerr incision or pubic incision is a type of abdominal surgical incision that allows access to the abdomen.

Objective: The Pfannenstiel incision is commonly used for gynecologic surgery. It is not known if this incision is associated with less postoperative pain compared to a vertical midline incision.Where is the Pfannenstiel incision made?
An extended Pfannenstiel incision was made from the ipsilateral anterior superior iliac spine to the lateral border of the contralateral rectus abdominis. A superiorly based flap was raised to expose the full length of the anterior rectus sheath from pubis to costal margin.
How do you do a Maylard incision?

What is Munro Kerr incision?
Kerr, Professor of Obstetrics and Gynecology at Glasgow University, presented a technique of cesarean section using a curved transverse incision made halfway down the lower uterine segment with the convexity directed downward.Why do surgeons avoid making vertical Pararectal incisions?
Pararectal incision Disadvantages include disruption of the innervation to the rectus lying medially.
Are muscles cut during abdominal surgery?If the vessels are difficult to isolate, then the muscles can be cut before ligating the vessels. This approach is used to expose the vessels that lie between the muscle and the peritoneum. To complete the incision, the transversalis fascia and peritoneum are incised transversely.
Article first time published onIs vertical or horizontal incision better?
A vertical incision (left) gives the surgeon greater access to your pelvis. A horizontal incision (right) follows your skin’s natural lines, usually leaving a thinner scar.
Why should you separate the rectus muscle bluntly?
Then, the rectus muscles (and pyramidalis muscles) are separated in the midline by sharp and blunt dissection. This act exposes the transversalis fascia and the peritoneum. The peritoneum is identified and entered at the superior aspect of the incision to avoid bladder injury.
Why would they do a vertical C section?
A vertical incision on the uterus causes less bleeding and better access to the fetus, but renders the mother unable to attempt a vaginal delivery (must have another repeat C-section) in the future.
What incision provides the best cosmetic result?
No incision provides wider pelvic exposure, and is relatively painless compared to midline incisions. Result is the most pleasing cosmetic result of any abdominal incision.
How many layers are cut during C section?
At the beginning of a caesarean section, six separate layers of the abdominal wall and uterus are opened individually.
Which artery should be found and ligated prior to the performance of a Maylard incision?
With the Maylard incision, once the anterior rectus sheath is incised in a transverse fashion, the fascia is not dissected free from the underlying rectus muscles; instead, the inferior epigastric arteries are identified and ligated, and the rectus muscles are incised, usually with electrocautery to minimize bleeding.

What is a lap procedure?
Laparoscopy is a type of surgical procedure that allows a surgeon to access the inside of the abdomen (tummy) and pelvis without having to make large incisions in the skin. This procedure is also known as keyhole surgery or minimally invasive surgery.
Which two arteries meet within the rectus sheath?
Superior Epigastric Arteries Descends within the rectus sheath (posterior to the rectus muscle but anterior to the posterior rectus sheath) to form an anastomosis with the inferior epigastric artery.
What does superior epigastric artery supply?
The superior epigastric artery is a terminal branch of the internal thoracic artery that contributes to the blood supply of the anterior abdominal wall. … Along its course, it gives several collateral branches that supply the muscles and the skin of the anterior abdominal wall.
What does the superficial epigastric artery supply?
The superficial epigastric artery supplies the superficial tissue of the abdominal wall; the superior and inferior epigastric arteries make an anastomosis with each other and supply the muscles of the abdominal wall.
What is Rutherford Morison incision?
Rutherford-Morison incision: similar with the Gridiron incision but the surgeon extends the incision into an oblique and curvilinear orientation, facilitating access to the ascending colon and sigmoid; also used for kidney transplantation.
What are midline incisions used for?
The midline incision (no. ①) is used for a wide array of abdominal surgery, as it allows the majority of the abdominal viscera to be accessed. A midline laparotomy can run anywhere from the xiphoid process to the pubic symphysis, passing around the umbilicus.
What is a Subumbilical incision?
In an effort to improve surgical exposure to the lateral pelvic sidewall with a transverse incision, Maylard proposed a transverse muscle-splitting incision. This incision usually refers to a subumbilical transverse incision. For gynecologic surgery, the incision is made 3-8 cm superior to the pubis symphysis.
What is Smead Jones closure?
(A) Smead-Jones closure. Far-far-near-near. Suture passes laterally through rectus sheath and peritoneum and adjacent fat. The suture crosses midline to pick up medial edge of fascia on opposite side of incision.
What is Muller Munro Kerr method?
(mŭn-rō′ kĕr) [John Munro Kerr, Scot. obstetrician, 1868–1955] A method used before the advent of ultrasonography to assess cephalopelvic disproportion, by manually comparing the size of the fetal head with that of the maternal pelvic brim.
What is kronig incision?

Which abdominal incision is better for healing?
Incision through the umbilicus has no negative effect on wound healing.

Lower abdominal incisions can also be midline, paramedian or pfannenstiel incisions.
