Nuss Procedure for Pectus Excavatum: Surgery, Hospital Stay, Pain, Bars, and Recovery

The Nuss procedure uses thoracoscopic guidance to place one or more curved bars behind the sternum and elevate the depressed chest wall. Surgery should be based on symptoms, anatomy, cardiopulmonary impact, age, and the child’s goals—not on a single index alone.

Not every child with pectus excavatum needs surgery

Mild pectus excavatum without functional or psychosocial impact can often be observed. Surgical evaluation becomes more relevant when the deformity is progressive, exercise tolerance is reduced, chest pain or cardiopulmonary compression is present, or body-image distress is substantial. The Haller index is useful, but it is only one part of the decision.

Preoperative evaluation may include physical examination, chest imaging, electrocardiography, echocardiography, pulmonary testing, or exercise testing. Symmetry, sternal rotation, chest-wall flexibility, scoliosis, and the patient’s growth stage influence planning.

How the Nuss procedure is performed

Under general anesthesia, small lateral chest incisions are made. A thoracoscope allows the surgeon to see the space behind the sternum and protect the heart and lungs. A shaped metal bar is passed behind the sternum and rotated so that its curve elevates the depressed chest. The number of bars and fixation technique depend on anatomy and stability.

“Minimally invasive” refers to smaller incisions; it does not mean the operation is painless. The chest wall is being remodeled, so structured multimodal analgesia, respiratory exercises, and early mobilization are important.

Hospital stay and the first postoperative days

Length of stay varies by age, pain pathway, and recovery. Discharge usually requires stable breathing and oxygen levels, adequate oral intake, safe walking, pain controlled with oral medication, and clear home-care instructions. Deep breathing, coughing, and gradual mobilization help prevent atelectasis and secretion retention.

Children should avoid forceful twisting, pulling themselves up with one arm, or sudden chest-wall loading. The care team will teach safer ways to turn, sit, and stand.

Pain and bar duration

Pain is usually greatest early and improves over the following weeks. Coughing, sneezing, turning, and abrupt movement may continue to cause tightness. Scheduled medication is often more effective than waiting until pain is severe.

The bars usually remain for several years while the chest wall remodels. Removal requires another operation. Bar displacement is uncommon but can occur after major impact or excessive early twisting. Any sudden severe pain, shortness of breath, fainting, fever, or visible change in chest contour requires prompt evaluation.

School, bathing, sleep, and exercise

Bathing depends on the dressing and wound status. Showering is often resumed before swimming or soaking. Return to school depends on pain, stamina, and transportation; backpack weight and physical education should be modified. Activity generally progresses from walking and breathing exercises to more demanding exercise only after follow-up assessment.

Contact sports, heavy lifting, pull-ups, push-ups, and forceful trunk rotation are restricted until the surgical team confirms that the chest and bars are stable.

Questions to ask before surgery

  • What are the goals of surgery for this child?
  • How many bars are expected and how will they be fixed?
  • What pain-control pathway is used?
  • When are school, swimming, instruments, and sports allowed?
  • How long will the bars remain, and what is involved in removal?

Frequently asked questions

Does every Nuss operation use two bars?

No. The number of bars depends on chest width, depression length, age, and stability.

Can CPR still be performed with a pectus bar?

Yes. In an emergency, CPR should not be delayed; responders should be told that chest-wall bars are present.

Can a child have MRI with a pectus bar?

It depends on the implant material and local policy. Always disclose the implant before MRI.
