Description of Procedure
A device called a speculum is inserted into the vagina to hold it open. The cryosurgery probe is inserted into the vagina. Nitrous oxide makes the tip extremely cold. The tip is touched to abnormal areas on the cervix. It is held there for a few minutes. The tip is removed. This allows the tissue to return to its normal temperature over the course of 3-5 minutes. This freezing and thawing cycle may be repeated several times for each abnormal area on the cervix.
You will remain lying down for at least ten minutes after the procedure. Some women may feel lightheaded and/or flushed after the procedure.
