When a woman has an ovarian teratoma, treatment should be determined based on the specific age of the woman, whether the teratoma is benign or malignant, and other factors.

For example, if the woman is relatively young and has a benign teratoma and wishes to preserve her fertility, she can undergo ovarian teratoma excision surgery, which can be performed either laparoscopically or through an open surgery. During the operation, the entire teratoma can be completely separated and placed in a specimen bag to prevent contamination of the woman's pelvic cavity and avoid chemical peritonitis or granuloma.

If the teratoma is malignant, then it is necessary to remove the adnexa and perform a comprehensive staging surgery. After surgery, based on the results of the pathological examination, it will be decided whether additional treatments such as radiotherapy or chemotherapy are needed.
