Teratomas are predominantly benign tumors, mainly located in the ovaries, although in some patients with unique physical constitutions, ovarian tissues may also ectopically end up in the pelvic area, forming a pelvic teratoma. Whether it is an ovarian teratoma or a pelvic teratoma, the scope of the surgery is typically medium-sized. If the surgery is an open operation, it is classified as a second-level surgery, and if it is performed using laparoscopy, it should be classified as a third-level surgery. Both second and third-level surgeries fall under the medium-sized category, and patients usually recover quite quickly after the operation. Typically, we advise patients to refrain from sexual intercourse, pelvic baths, and to avoid heavy physical labor within a month post-operation.
