Does Pectus Excavatum Get Worse With Age? Treatment Options for Adults
Pectus excavatum — a structural difference in which the breastbone and rib cartilage curve inward — has long been treated as a childhood-only condition, but that picture is changing. A comprehensive review aimed at primary care physicians reports that pectus excavatum can present very differently across the lifespan: some patients first notice symptoms during the adolescent growth spurt, while in one reviewed cohort 36% of adult patients reported new symptom onset after age 20, and more than 53% noticed progression after age 18 [1].
That finding challenges the assumption that pectus excavatum is purely a pediatric issue that resolves by adulthood. According to the same review, many adult patients first see a doctor not because of the chest's appearance but because of fatigue, reduced exercise tolerance, or chest discomfort that shows up in their 30s or 40s [1]. So the real question isn't simply "does pectus excavatum get worse with age" — it's a more nuanced one: why do its effects become more noticeable in some patients later in life?
In this article we look at how pectus excavatum tends to change over a lifetime, why symptoms show up for the first time in some adults, and what treatment options are realistic once someone is past childhood. Our aim isn't to offer a fixed prognosis or claim it "definitely gets worse" past a certain age — it's to lay out what the literature actually says, in plain language.
Childhood and Adolescence: The Growth-Spurt Connection
Pectus excavatum is usually noticed in infancy, but it tends to become more visible during the adolescent growth spurt. Because the rib cage and cartilage grow rapidly during this period, a previously mild indentation can become far more noticeable; what families often describe as a sudden change is really a gradual process becoming visible all at once.
This is one reason most centers now prefer to delay any surgical decision until after puberty rather than operating in early childhood [1]. Conservative options such as the Gvacuum vacuum bell — a device that applies controlled external suction to the chest wall — are generally considered during the years when growth potential and cartilage flexibility are still high; the literature reports the most consistent results in children under 11, with the expected benefit declining as a person gets older [1].
A question that comes up often here: if a mild case is left alone through childhood, does it correct itself once growth is complete? The literature suggests the chest wall's structural shape doesn't tend to change on its own after growth stops — what mostly changes afterward is the wall's flexibility and the effects tied to it, which is the subject of the next section.
Symptoms That First Show Up in Adulthood
Some adults had a mild chest asymmetry or indentation noticed in childhood that was never followed up on. Years later, often in their 30s or 40s, they return to the topic when they see a doctor for exertional fatigue, shortness of breath, or chest discomfort [1][2].
A study of patients over 50 shows that a meaningful share of these presentations were initially misread. In that study of 42 symptomatic senior patients, roughly 45% first developed complaints in their 40s or 50s, and 63% were initially labeled as having "unexplained cardiovascular complaints" [2]. In other words, fatigue or palpitations linked to pectus excavatum can be mistaken for something else until the real cause is identified — sometimes after years of workups in other specialties.
Why Does the Chest Wall Stiffen With Age?
A consistent finding across the literature: the rib cage loses flexibility with age. The same senior-patient study reports that as the chest wall stiffens, the body loses some of its earlier ability to compensate — for example through slight lateral shifting — for the pressure the deformity places on the heart [2]. A recent surgical review echoes the same idea: as a patient ages, the chest wall can become less flexible, and this can lead to progression of symptoms [3].
The practical takeaway: pectus excavatum itself doesn't necessarily worsen in every patient, but the chest wall's increasing stiffness with age can make previously subtle effects far more noticeable. The same review reports that nearly half of adult patients first develop symptoms in their 4th or 5th decade (their 30s and 40s) [3]. That's not the same as saying "pectus excavatum always gets worse with age" — but it is a pattern worth taking seriously.
This stiffening process varies a lot from person to person. General health, posture habits, overall musculoskeletal flexibility, and whether another spinal or chest wall difference is present can make two patients of the same age follow very different paths. That's why the current literature can't offer one universal age cutoff or timeline that applies to everyone.
Treatment Options in Adulthood: Conservative or Surgical?
For an adult being evaluated for pectus excavatum for the first time, the treatment calculus looks different than it does in childhood. Conservative approaches like the Gvacuum vacuum bell can still be considered in younger adults whose chest wall is relatively flexible, but the literature is clear that these devices show their strongest results in younger age groups, with the expected contribution declining as the chest wall stiffens [1]. That means no single approach can promise the same outcome for every adult patient — the right option depends on chest wall flexibility, the severity of the deformity, and the patient's own priorities, worked out with a specialist.
On the surgical side, minimally invasive repair (the Nuss procedure) — once considered a technique reserved for children and teens — is now reported to be used successfully in patients as old as their 70s [3]. Because an adult chest wall tends to have more calcification and rigidity, the procedure is technically more complex than in children; adults often need 2–3 bars instead of one, and the bars typically stay in place longer (roughly 3 to 3.5 years) than in pediatric patients [3]. In selected cases — for example significant asymmetry or a combination with pectus carinatum — open surgical repair is still considered [3].
One important distinction: conservative and surgical options aren't direct substitutes for each other — they suit different patient profiles. A young adult with a moderate deformity and a chest wall that's still reasonably flexible may reasonably try a conservative option first, while someone with a markedly stiffened chest wall and a measurable cardiopulmonary effect is more likely to be steered toward a surgical evaluation. Making that distinction is exactly what a hands-on specialist assessment is for.
Frequently Asked Questions
Does pectus excavatum resolve on its own in adulthood? According to the literature, no — the chest wall's structural shape doesn't tend to change significantly on its own once growth is complete. What changes with age is mostly the wall's flexibility and the effects tied to it, not the shape itself.
Is the Gvacuum vacuum bell still an option in adulthood? Yes, but expectations should be set differently than in childhood. The literature reports the strongest effect in younger age groups with more flexible chest walls, with the contribution potentially changing as a person ages [1]; for that reason, trying a Gvacuum vacuum bell as an adult should be approached with realistic expectations and under a specialist's guidance.
Does an adult with no symptoms — just concerns about appearance — need to act urgently? No; without signs like exertional fatigue, shortness of breath, palpitations, or chest pain, this isn't an emergency. Still, an evaluation can be worthwhile both to learn about the available options and to rule out any cardiopulmonary effect.
When to See a Specialist
A chest wall indentation noticed or newly prominent in adulthood isn't an emergency on its own — but if it comes with exertional fatigue, shortness of breath, palpitations, or chest pain, evaluation shouldn't be delayed. Which specialty is the right first stop depends on the specific findings — thoracic surgery, orthopedics, physical medicine and rehabilitation, and, for exertion-related symptoms, cardiology can all play a role in this kind of evaluation.
Pectuslab focuses on non-surgical, conservative solutions — vacuum bell therapy and bracing — for chest wall differences such as pectus excavatum and pectus carinatum. Which approach, conservative or surgical, is right for an adult patient can only be determined through an individual evaluation; the information in this article offers a general framework, not a personal treatment recommendation.
In short, pectus excavatum doesn't automatically get worse in every adult — but the chest wall's declining flexibility with age can make previously unnoticed effects more apparent in some patients. Whether it was noticed for the first time in adulthood or has been known since childhood, the right next step is the same: take any symptoms seriously and get evaluated by the right specialist.
