Although most teratomas are benign tumors, they can be very harmful to a woman’s body, and surgery is the best treatment for teratomas. The surgery depends on the type of surgery chosen. Different surgical methods have different operations, including traditional open surgery and minimally invasive hysteroscopic surgery. The best surgical procedure for teratoma at this stage is laparoscopic surgery, but its technical requirements are very high and if the teratoma ruptures during the microscopic debridement, peritoneal implantation and chemical peritonitis may occur. In most cases, the normal ovarian tissue on the affected side and the contralateral ovary can be preserved, or not removed if no abnormality is seen during the preoperative ultrasound and intraoperative exploration. The surgical procedure for teratoma usually involves complete excision of the diseased tissue, because the boundary between teratoma and normal tissue is relatively clear. Traditional surgery is used less often, mainly because it is more invasive, and recovery is slower and more painful for the patient, so most patients choose to have minimally invasive surgery for removal. After teratoma surgery, regular review is needed, because teratoma is divided into malignant and benign ones.
