Which cervical surgery is better, Lipo knife or cold knife, depends on the situation, as follows: 1. Cold knife surgery is good: if the possibility of cervical tumor is suspected to be higher, conization of the cervix is performed mainly to clarify the degree of cervical lesion, it is recommended to choose cold knife surgery to be better. Cold knife surgery will not destroy the edges of the cervical tissues for examination after removal, so further examination is needed if problems are found at the edges during the examination. If the patient is mainly because of cervical hypertrophy or other problems to perform cervical surgery, there is no possibility of tumor, this situation can choose the lip knife surgery.
