The Joel-Cohen incision for cesarean section differs from a Pfannenstiel incision in which way?
- A Joel-Cohen is a curved low transverse incision below the pubic hairline, while Pfannenstiel is straight
- B Joel-Cohen requires sharp dissection of the rectus sheath while Pfannenstiel uses blunt entry
- C Joel-Cohen is a straight horizontal incision 3 cm above the symphysis pubis with blunt extension, while Pfannenstiel is curved and lower ✓
- D Joel-Cohen avoids the subcutaneous fat layer entirely
Correct answer: C. Joel-Cohen is a straight horizontal incision 3 cm above the symphysis pubis with blunt extension, while Pfannenstiel is curved and lower
Explanation
The Joel-Cohen technique uses a straight (not curved) transverse skin incision made 3 cm above the symphysis pubis (higher than the Pfannenstiel, which is in the skin crease just above the pubic symphysis). The fascial layer is opened with sharp scissors and then extended bluntly with fingers. Rectus muscles and peritoneum are separated bluntly. The Misgav-Ladach cesarean section is based on the Joel-Cohen technique. Studies show Joel-Cohen is associated with shorter operative time and less blood loss compared to Pfannenstiel.
