An episiotomy is to be performed in a primigravida in labor. Which of these is an advantage of mediolateral episiotomy over midline episiotomy?

Explanation

Ans: A. Less chance of extension (Ref: Williams 24/e p551).A mediolateral episiotomy is preferred because it has a much lesser chance of extension through the perineum till anal sphincter, though there is increased risk of blood loss and it is difficult to repair.
