Like the laser treatment, cryotherapy is an ablation therapy. It uses nitrous oxide to freeze the abnormal area. This technique, however, is not optimal for large areas or areas where abnormalities are already advanced or severe. After the procedure, women may experience a significant watery vaginal discharge for several weeks. As with laser ablation, significant complications of this procedure are rare. They include narrowing (stenosis) of the cervix and delayed bleeding. Cryotherapy also destroys the abnormal area and is generally felt to be inappropriate for women with advanced cervical disease.

Loop electrosurgical excision procedure (LEEP)

Loop electrosurgical excision procedure, also known as LEEP, is an inexpensive, simple technique that uses a radio-frequency current to remove abnormal areas. It is similar, but less extensive than a cone biopsy. It has an advantage over the destructive techniques in that an intact tissue sample for analysis can be obtained for pathologic study. Vaginal discharge and spotting may occur after this procedure. Complications rarely occur in women undergoing LEEP, and include cervical narrowing (stenosis) that may interfere with fertility and potentiall cause premature labor in a subsequent pregnancy.

Cold knife cone biopsy (conization)

Cone biopsy (conization) was once the primary procedure used to treat cervical dysplasia, but the other methods have now replaced it for this purpose. However, when a physician cannot view the entire area that needs to be seen during colposcopy, a cone biopsy is typically recommended. It is also recommended if additional tissue sampling is needed to obtain more information regarding the diagnosis. This technique allows the size and shape of the sample to be tailored to the condition. Cone biopsy has a slightly higher risk of cervical complications than the other treatments, which can include postoperative bleeding and cervical narrowing (stenosis) that may interfere with fertility and also premature labor.
