Final answer:
The option that is not a variation of the transverse incision is d. McBurney, which is actually an oblique incision used for appendectomies. The other options are variations of the transverse incision used typically in abdominal surgeries.
Step-by-step explanation:
The student's question asks to identify which option is not a variation of the transverse incision used in surgical procedures. A transverse incision is a horizontal cut made across the body, often used in abdominal surgery.
The correct answer to the question is d. McBurney, which is not a transverse incision but rather an oblique incision typically used for an appendectomy. On the other hand, Pfannenstiel, Maylard, and Cherney incisions are all types of transverse incisions:
- The Pfannenstiel incision is commonly used for Cesarean sections and hysterectomies.
- The Maylard incision provides better exposure to the pelvic organs by cutting the rectus muscles.
- The Cherney incision allows excellent exposure for surgeries involving the bladder, urethra, and vagina, as it detaches the muscles from the pubic bone.
