In Short

In the NUSS procedure, a metallic bar is placed beneath the chest cage through two small incisions. This bar pushes the sunken chest wall outward into a normal position. After 2-3 years, the bar is removed. The chest cage retains its corrected shape.

Who Is a Candidate?

Suitable Candidates

  • Pectus excavatum diagnosis (Haller index >3.2)
  • Cardiac or pulmonary compression symptoms
  • Social/psychological impact (body image)
  • Age: 10-50 (ideal)

Not Eligible

  • Severe osteoporosis
  • Connective tissue disorders (relative contraindication)
  • Very advanced age (>50 — relative)

How the Procedure Works

1
1. Two Small Incisions
Two 2-3 cm incisions are made on either side of the chest.
2
2. Bar Passage
Under thoracoscopic guidance, a bar shaped to the patient's anatomy is passed beneath the sunken area.
3
3. Bar Flip
The bar is rotated to push the chest cage outward and is secured to the ribs.
4
4. 2-3 Year Retention
The bar remains until the chest cage has remodeled, then is removed.

Benefits & Expected Outcomes

  • Excellent cosmetic results
  • Cardiac compression eliminated
  • Increased exercise capacity
  • Improved body image and self-confidence

Risks & Complications

⚠️ As with any medical procedure, there are risks. The following is evidence-based information.

  • Bar displacement (2-5%)
  • Infection (1-2%)
  • Pneumothorax
  • Pericarditis (rare)
🧲 MR Conditional — Bar & MRI Compatibility
Most modern bars (especially those made of titanium) are classified as "MR Conditional." This means that the patient can undergo an MRI scan, but only under specific conditions (e.g., maximum 1.5 Tesla, without exceeding a specific SAR [Specific Absorption Rate] limit, and by using specialized sequences). With stainless steel bars, however, avoiding MRI scans until the bar is removed (typically 2 to 3 years) is advised unless it is an emergency, and alternative imaging modalities such as CT (Computed Tomography) are preferred.

I lived with this condition for 18 years. Three months after surgery, I went to the beach for the first time and swam without a shirt.
