What is Pectus Excavatum?
Pectus excavatum is a condition present from birth that causes the breastbone (sternum) and some ribs to grow inward, creating a depression in the chest. While often a standalone condition, it can be associated with other connective tissue or skeletal disorders, such as Marfan syndrome or scoliosis. The severity can range from mild, with purely cosmetic concerns, to severe, where the indentation may press on the heart and lungs, causing physiological symptoms. It often becomes more prominent during the adolescent growth spurt.
Symptoms and Diagnosis
For those with a mild condition, symptoms may be non-existent. However, as the indentation deepens, particularly during puberty, it can lead to various issues.
Potential Symptoms
- Shortness of breath, especially during exercise
- Fatigue or decreased stamina
- Chest pain or pressure
- Rapid heartbeat or palpitations
- Poor posture, such as rounded shoulders
- Concerns about body image and self-esteem
Diagnostic Process
Diagnosis typically begins with a physical exam and medical history review. Imaging tests are crucial for determining the severity and potential impact on internal organs.
- CT scan or MRI: Provides a detailed, cross-sectional view of the chest to measure the depth of the deformity and assess any heart or lung compression. A Haller Index, a ratio derived from the CT scan, is often used to grade severity.
- Echocardiogram: An ultrasound of the heart to check its function and position.
- Pulmonary Function Tests: Measures lung capacity and function.
Surgical Treatment Options
For moderate to severe cases, particularly those causing physiological symptoms, surgical correction is the standard of care. There are two primary surgical procedures.
The Nuss Procedure
This minimally invasive technique is now the most common repair for pectus excavatum. It involves:
- Making small incisions on each side of the chest.
- Inserting a tiny camera (thoracoscope) to guide the procedure.
- Passing a custom-curved metal bar under the breastbone.
- Flipping the bar to push the sternum outward into a normal position.
- Securing the bar in place.
The bar remains in place for approximately two to three years before being removed in an outpatient procedure.
The Ravitch Technique
This traditional, open-chest procedure is less common today but may be used for more complex or asymmetrical cases, particularly in adults where the cartilage is less pliable. It involves:
- A larger incision made down the center of the chest.
- Removing the deformed costal cartilage.
- Repositioning the breastbone.
- Using hardware like a metal strut to hold the sternum in the corrected position while it heals.
Non-Surgical and Cosmetic Alternatives
For individuals with mild pectus excavatum, surgery may not be necessary. Other options can improve aesthetics and function.
Vacuum Bell Therapy
This non-invasive option uses a bell-shaped device that creates suction to lift the breastbone. It is often recommended for children and adolescents whose chests are still pliable and can lead to significant correction over time with consistent use.
Physical Therapy and Exercise
While exercise alone cannot fix the deformity, a targeted physical therapy routine can improve posture, strengthen chest and back muscles, and increase chest wall flexibility. This can help improve the cosmetic appearance and mitigate some symptoms. Swimming, in particular, is often recommended.
Cosmetic Fillers and Implants
For mild cases without functional symptoms, cosmetic solutions are available. Silicone implants or dermal fillers can be injected to fill the depression and create a smoother chest contour.
Comparison of Treatment Options
| Feature | Nuss Procedure | Ravitch Technique | Vacuum Bell Therapy | Cosmetic Fillers/Implants |
|---|---|---|---|---|
| Invasiveness | Minimally Invasive | Open Surgery | Non-invasive | Minimally Invasive |
| Ideal Candidate | Children, adolescents, and some adults with pliable chests | Older patients or complex, asymmetrical deformities | Young patients with mild to moderate cases | Mild cosmetic concerns only |
| Effectiveness | High success rate with lasting correction | Effective for complex cases, with good cosmetic results | Can provide significant correction, especially with early treatment | Primarily for aesthetic improvement |
| Recovery | Several weeks, involves managing pain from bar placement | Longer recovery due to more extensive surgery | No recovery time, but requires consistent, long-term use | Minimal downtime, depending on the procedure |
| Risk | Bar displacement, pneumothorax (less common now), infection | Higher rates of bleeding, air leaks, longer hospital stay | Rare complications if used correctly | Risk of infection, uneven results |
| Bars/Hardware | Temporary metal bar removed after 2-3 years | Hardware (strut or mesh) may be used and removed later | No hardware, just a suction device used externally | Silicone implants or dermal fillers |
Recovery and Long-Term Outlook
Recovery from surgical repair varies based on the procedure. The Nuss procedure typically involves a few days in the hospital for pain management, followed by activity restrictions for several weeks. Pain management, including cryoablation or epidurals, has significantly improved patient comfort. Patients are encouraged to use an incentive spirometer to expand their lungs. Once the bar is removed, often after two to three years, the chest wall retains its corrected shape. Long-term studies show high patient satisfaction with both cosmetic appearance and improved physiological function.
For non-surgical treatments like vacuum bell therapy, commitment to a daily routine over an extended period is necessary for successful correction. Regardless of the chosen path, regular follow-up with a medical professional is key to monitoring progress and ensuring the best outcome.

Conclusion
While a "chest hole" can be a source of physical discomfort and emotional distress, modern medicine offers highly effective ways to address and correct the condition. For severe cases, surgery can provide a lasting solution with high patient satisfaction. For milder cases, non-invasive therapies like vacuum bells or cosmetic procedures offer viable alternatives. The right approach depends on the individual's specific circumstances, making a consultation with a thoracic surgeon or other specialist essential for determining the best course of action.
