Pectus excavatum surgery (Nuss and Ravitch) vs conservative treatment
By Javier Santana, founder of Pectus Academy · Updated October 2026
Short answer: surgery is the established treatment when pectus is severe or affects the heart or lungs. It changes the structure right away, in exchange for an operation with its risks. Conservative treatment (vacuum bell, physical therapy and exercise) carries less risk and gives more modest, less certain results. They are not rivals: the choice depends on severity, symptoms and age, and is made with a thoracic surgeon.
What does each operation involve?
- Nuss procedure: the most common. Through small incisions on the sides of the chest, a curved metal bar is placed under the breastbone and pushes it outward. Sometimes more than one bar is needed. They are removed after two or three years.
- Ravitch technique: older and less common. Through a larger incision down the center of the chest, the deformed cartilage is removed and the breastbone is fixed in its new position.
When is surgery done?
The main reason is that the dip affects the heart or lungs, rather than appearance. The Haller index is used as a reference: above 3.2 is considered a severe deformity. Current practice is to wait until after the growth spurt of puberty.
What are the risks?
The complications described are bar displacement, infection, pneumothorax, bleeding and recurrence. They are more frequent in adults: in a registry of 2,843 patients, adults had more bleeding (3% vs 0.86%) and more acute pain (55% vs 39.1%) than minors.
What results does it give?
- The improvement in appearance is obvious, and most people who have surgery are satisfied.
- The improvement in function is less clear: gains in lung tests tend to fade over time, and a meta-analysis found no significant change in maximum oxygen uptake before and after surgery.
Surgery and conservative treatment, side by side
| Surgery | Conservative treatment | |
|---|---|---|
| What changes | The position of the breastbone, right away | Posture and muscle; with the vacuum bell, depth in some cases |
| Timeline | One operation and two or three years with the bar | Months or years of daily work |
| Risks | Those of chest surgery | Minor; with the vacuum bell, mostly skin-related |
| Evidence | Extensive | Limited, and almost all in children and teenagers |
| Who it is for | Severe or symptomatic pectus | Mild or moderate pectus with no effect on the heart or lungs |
How to decide
- Get assessed: a physical exam and, if the doctor thinks it is needed, a CT scan, echocardiogram, lung function tests and exercise testing.
- If the heart or lungs are affected, the conversation is with the surgeon.
- If they are not, you can start with the conservative route and be reassessed later.
I did not have surgery. For years I thought it was the only option, but it scared me and I did not want to give up sports for that long. That is not advice: it is what I decided.
What we know and what we don't
What we know
- Surgery clearly changes appearance, and most people are satisfied.
- Adults have more complications than minors.
What we don't know
- How much physical capacity improves in the long term after surgery.
- How surgery and the vacuum bell compare head to head in moderate cases.
