Median Episiotomy vs. Mediolateral Episiotomy. This multi-image surgical exhibit compares the benefits of a mediolateral episiotomy versus that a median episiotomy during childbirth. The medical illustrations demonstrate that a median incision carries greater involvement and risk of damage to the external anal sphincter muscle and rectal mucosa. The potential for injury can be lessened, typically, by a mediolateral incision.
