Carbon Dioxide Laser Surgery for Abnormal Cervical Cell Changes
A carbon dioxide (CO2) laser beam is used to:
Laser vaporization takes 10 to 15 minutes. The abnormal tissue is destroyed or removed, leaving normal tissue intact.
How it is done
Carbon dioxide laser surgery can be done in your doctor's office, a clinic, or a hospital as an outpatient procedure. You do not have to spend the night in the hospital.
You will need to take off your clothes below the waist and drape a paper or cloth covering around your waist. You will then lie on your back on an exam table with your feet raised and supported by footrests (stirrups). Your doctor will insert a lubricated tool called a speculum into your vagina. The speculum gently spreads apart the vaginal walls, allowing the inside of the vagina and the cervix to be examined.
The procedure is usually done with a numbing medicine injected into the cervix (cervical block). If a cervical block is used, an oral pain medicine may be used along with the local anesthetic.
What To Expect After Surgery
Most women are able to return to normal activity within 2 to 3 days after surgery. Recovery time will depend on how much was done during the procedure.

How Well It Works
Carbon dioxide laser surgery works well for destroying abnormal cervical tissue, depending on the size, depth, and type of abnormal tissue. Studies have had differing results. They show that carbon dioxide laser surgery destroys all of the abnormal tissue in 77 to 98 out of 100 cases.1 And when this surgery is used to remove a wedge of abnormal tissue, it is successful in about 93 to 97 out of 100 cases.1
What To Think About
Carbon dioxide laser surgery is able to destroy or remove abnormal tissue that is too high in the cervix to be destroyed with cryosurgery.
A carbon dioxide laser can be used to perform a cone biopsy (conization), but is not used as frequently as other conization methods because:
If you have carbon dioxide laser surgery, you need regular follow-up Pap tests. You should have a Pap test in 4 to 6 months or as often as recommended by your doctor. After several Pap test results are normal, you and your doctor can decide how often to schedule future Pap tests.
