Cervical conization is the most important measure in the management of CIN III, which is both diagnostic and therapeutic in terms of cervical lesions. After conization, the postoperative pathological results are the most important and the corresponding treatment according to the results is even more important, which is one of the reasons why conization must be done. Through conization, patients who clearly have CINIII can choose hysterectomy if they do not have fertility requirements and are older; while for those who are younger and have fertility requirements, the uterus can be preserved for close follow-up; and when conization confirms that the patient has cervical carcinoma in situ, hysterectomy is usually required if there is no fertility requirement, but for those who still have fertility requirements, attempts can be made under close surveillance to However, for patients who still have fertility requirements, pregnancy can be attempted under close monitoring; when conization confirms early invasive carcinoma and fertility requirements, radical hysterectomy can be considered to preserve the uterus and artificially assist pregnancy, while for patients without fertility requirements, hysterectomy and radical cervical cancer treatment can be performed.
