Abstract: In recent years, more and more cervical intraepithelial neoplasia are diagnosed following the extensive cervical screening. The number of patients who need cervical conization is also gradually increased. It is predictable that many patients have fertility requirements. Cervical healing after conization, and whether or not to increase adverse outcomes of pregnancy, receives much concern. Ultrasound as a morphology research method can be used to evaluate the time and degree of cervical healing, and to measure the cervix length and shape, so as to predict adverse outcomes of pregnancy. In this paper, we reviewed the application of ultrasound in evaluating the prognosis of cervical conization, including methodological standard and quantitative analysis.
