Pectus excavatum (sunken chest, funnel chest) is the most common
abnormality of the chest in children. It can present as a wide
range, from mild depression of the sternum (breastbone) to severe
cases where the sternum nearly touches the spine.
How it Occurs
of the rib cartilage causes the sternum to be pushed inward. The
depression in the breastbone may be even or deeper on one side. The breastbone may be
straight or rotated to one side. The condition can become visible in variety of ages – forom infancy to older children during a growth spurt.
The cause of these abnormalities is unknown, though there is a
familial tendency (25% of patients report a family history of chest
Not all children with pectus excavatum require surgery. Some mild
forms can be improved with upper-body strengthening exercises and
improvement in posture.
Moderate to severe chest depression
A minimally invasive approach is used to treat the condition surgically. This operation involves making an incision on
each side of the chest about 1.5 inches long. A stainless steel bar that is
curved to fit around the front of the chest is slid under the
breastbone from one of the side incisions and passed to the other
side. The bar is left in place for
approximately three years to allow the chest to reshape. After three years
have passed, the bar will be removed in a same-day surgery
What to Expect Before Surgery
Before surgery a CT (CAT scan) will be taken of your
child's chest. The scan will measure the chest depression and also see whether the heart and/or lungs are crowded. The CT scan is not
painful. To have a CT, your child will need to lie still for about
5-10 minutes while a series of pictures are taken.
A list of exercises will be given to your child to help
strengthen the chest muscles. These exercises are to be done before
surgery and after surgery as well. Deep breathing and posture
exercises to maintain a "military" posture (shoulders back with
back in straight alignment) will also be extremely beneficial.
Your insurance company may require additional testing to
approve your child's surgery. If additional testing is required by
your insurance we will make arrangements for these exams to be
completed. Most insurance companies will not begin the
precertification process notifying you of this requirement until
2-3 months prior to the scheduled surgery date. This may cause some
difficulty for families who would like to plan their surgery ahead
of time. Please be aware that if your insurance company denies the
surgery for approval, the appeal process may be lengthy. In some
cases, the surgery date may need to be postponed and
Before and After Surgery

Pain management is a very important issue for pectus surgery
patients. Patients will require a variety of pain medication
post-operatively, including extended-release medications. These
medicines must be taken in a pill form and are not available as a
liquid. It is important for your child to be able to swallow pills
prior to their operation. Some may want to practice becoming
proficient at pill-swallowing…try Tic-Tacs and a cup of water!
The pain medication required after the surgical procedure often
causes constipation. It is extremely important to start MiraLAX before the scheduled surgery date. It will be part of your
discharge instructions as well, so you may want to purchase the

Care of the Incisions
When your child comes out of the operating room, they may have a
bandage over each incision. These outer bandages may be removed two
days following surgery. Underneath these dressings are white
steri-strips over the incisions. Do not pull these off, they will
curl up and fall off on their own as the incisions heal. If
steri-strips are still on after one week, you may gently remove
them (try rubbing gently with washcloth while showering). The
incisions are closed using dissolving stitches that are beneath the
skin. There are not any stitches that will need to be removed. The
incisions will be pink at first, then will gradually fade over the
next year. Notify your child's doctor if there is any redness,
increased swelling, or drainage from the incisions.
Activity will be very limited the first 1-3 post-operative
months. This is done so the bar is not dislodged. This will mean
your child cannot participate in sports or physical education
for at least 1-3 months after surgery. After 1-3 months, your child
may participate in any activities that he/she can comfortably
tolerate EXCEPT for contact/action sports.
In the first 1-3 post-operative months, your child will not be
allowed to lift anything that weighs more than 25 pounds.
Contact sports (i.e. football, wrestling, etc.) will not be
allowed for at least 6 months. After 6 months your
child may return to contact sports or any other prior activities.
However, the risk of bar rotation or another problem requiring
additional operations is unknown and you would assume this risk for
activities such as contact and action sports.
After your child has recovered, the exercises for the chest strengthening should be restarted.
Usually children need to be home for about 1-2 weeks after
this surgery. Your child may return to school when energy level and
pain control permits.
He or she may not participate in PE or recess for the first 1-3
months or carry heavy books due to discomfort. You may need to make
arrangements for books to be placed in the classroom instead of
having your child carry them.
Walking up or down stairs is allowed anytime. Your
post-operative letter will outline this information for your
child's school or work.
We will want to see your child 2-4 weeks after the
operation, then 3 months post-operatively and then yearly until it
is time for the bar to come out. It is important to keep these
appointments to monitor your child's outcome and determine when the
bar can be removed. If an appointment is not scheduled when you
leave the hospital, please call the South Surgery Clinic (913)
