Some considerations regarding ovarian dermoid cyst removal include the reason for the procedure, surgical risks and the expected outcome, according to WebMD. A doctor may recommend surgery if the cyst is large, if cysts are present on both ovaries or if there are reasons to suspect cancer.
Dermoid cysts of the ovaries can cause complications if they grow too large, according to Women's Health Advice. Some complications include abdominal pain, vaginal bleeding, painful intercourse, unexplained weight gain and ovarian torsion. Ovarian torsion is a serious condition where the ovary twists and cuts off its blood supply, causing intense pain. Even if the cyst is not yet causing these complications, the doctor usually recommends surgery.
The surgery to remove the dermoid cyst may be a laparoscopy or laparotomy, according to WebMD. With laparoscopy, the surgeon only makes a small incision, and recovery times are faster. Sometimes the surgeon can remove the cyst and leave the rest of the ovary intact. Other situations require complete removal of the ovary with a laparotomy, which requires a larger incision and a longer hospital stay to recover. The risks associated with surgery include the possibility of the cyst growing back, lingering pain, scar tissue on the ovaries, infection and possible damage to the bowel or bladder.
One study of the recurrence of ovarian dermoid cysts showed that after the laparotomy, there was a 7 percent chance of recurrence, reports Women's Health Advice. With the more invasive laparotomy, the recurrence after two years was 0 percent.
