Cervix cryosurgery
Cervix cryosurgery is a procedure to freeze and destroy abnormal tissue in the cervix. The cervix is the lower part of the uterus (womb) that opens at the top of the vagina. Abnormal changes in the cells on the surface of the cervix is called cervical dysplasia.
Cervix
The cervix is the lower end of the womb (uterus). It is at the top of the vagina. It is about 2. 5 to 3. 5 centimeters (1 to 1. 3 inches) long. Th...

Cryotherapy is done in the health care provider's office while you are awake. You may have slight cramping. You may have some amount of pain during the surgery.
To perform the procedure:
- An instrument is inserted into the vagina to hold the walls open so that the provider can see the cervix.
Vagina
The vagina is the female body part that connects the womb (uterus) and cervix to the outside of the body.

- Compressed nitrogen gas flows through the instrument, making the metal cold enough to freeze and destroy the tissue.
An "ice ball" forms on the cervix, killing the abnormal cells. For the treatment to be most effective:
- The freezing is done for 3 minutes
- The cervix is allowed to thaw for 5 minutes
- Freezing is repeated for another 3 minutes
Why the Procedure Is Performed
This procedure may be done to:
- Treat cervicitis

Your provider will help you to decide if cryosurgery is right for your condition.
Risks
Risks of any surgery are:
- Bleeding
- Infection
Cryosurgery may cause scarring of the cervix, but most of the time, it is very minor. More severe scarring may make it more difficult to get pregnant, or cause increased cramping with menstrual periods.
Before the Procedure
Your provider may suggest you to take medicine such as ibuprofen 1 hour before the procedure. This may reduce pain during the procedure.
After the Procedure
You might feel lightheaded right after the procedure. If this happens, lie down flat on the examination table so that you do not faint. This feeling should go away in a few minutes.
You can resume almost all of your normal activities right after surgery.
For 2 to 3 weeks after the surgery, you will have a lot of watery discharge caused by the shedding (sloughing) of the dead cervical tissue.
You may need to avoid sexual intercourse and using tampons for several weeks.
Avoid douching. This can cause severe infections in the uterus and tubes.
Outlook (Prognosis)
Your provider should do a repeat Pap test or biopsy at a follow-up visit to make sure that all abnormal tissue was destroyed.
Pap test
The Pap test mainly checks for changes that may turn into cervical cancer. Cells scraped from the opening of the cervix are examined under a microsc...
