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.
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
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.

Carbon dioxide laser surgery is done
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.footnote 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.footnote 1
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.
