Cervical conization surgery does not require sutures. The surgical method of cervical conization is to use a lap knife to perform local excision of the cervical lesion, which is called cervical conization because of the cone-like excision of the lesion. The cervical area usually has a lot of secretions and mucus, so after the cervical conization, anti-inflammatory treatment is needed to avoid cervical infection, and sexual intercourse is prohibited for a period of time after the surgery.
