Pectus Excavatum ( Funnel Chest ) : Causes, Symptoms, Diagnosis, and Treatment

Pectus Excavatum ( Funnel Chest )

Pectus Excavatum, commonly known as Funnel Chest, is a congenital chest wall deformity that affects the shape and structure of the chest. While it may not always pose serious health risks, its impact on physical appearance and potential associated symptoms can make it a significant concern for those affected. In this blog post, we’ll delve into the details of Pectus Excavatum, exploring its causes, symptoms, diagnosis, and available treatment options.

Pectus Excavatum ( Funnel Chest ) occurs when the breastbone (sternum) and the ribs grow abnormally, causing the chest to develop a sunken or caved-in appearance. This condition is often noticeable from an early age but can become more pronounced during the adolescent growth spurt.

Here are some key factors associated with the causes of Pectus Excavatum:

  • Genetics:
    • There is evidence suggesting a genetic predisposition to Pectus Excavatum. The condition can run in families, indicating a hereditary component.
    • Specific genetic factors that may influence the development of this chest deformity are still under investigation.
  • Connective Tissue Abnormalities:
    • Some research suggests that an overgrowth or abnormal development of connective tissue, including cartilage, in the chest area may contribute to the formation of Pectus Excavatum.
    • The imbalance in the growth of cartilage and bone during the developmental stages could lead to the characteristic inward curvature of the sternum.
  • Muscular Imbalances:
    • Muscular imbalances in the chest area may play a role in the development of Pectus Excavatum. If certain chest muscles are weaker or tighter than others, it could influence the positioning of the sternum.
  • Postural Factors:
    • Poor posture, especially during crucial growth phases in childhood and adolescence, might contribute to the progression of Pectus Excavatum.
    • Incorrect posture may place uneven stress on the chest, potentially influencing the development of the deformity.
  • Environmental Factors:
    • While genetic factors are considered significant, environmental factors may also contribute to the development of Pectus Excavatum. These could include prenatal factors, exposure to certain substances, or environmental influences during critical periods of growth.
  • Rapid Growth Spurts:
    • The condition often becomes more noticeable during the adolescent growth spurt when the body undergoes significant changes. Rapid growth may exacerbate the chest wall deformity.
  • Other Medical Conditions:
    • Pectus Excavatum has been associated with certain connective tissue disorders, such as Marfan syndrome and Ehlers-Danlos syndrome, which further underscores the role of genetic factors.

Pectus Excavatum, or Funnel Chest, can manifest with a range of symptoms, and the severity of these symptoms can vary among individuals. While some people with Pectus Excavatum may not experience significant issues, others may face more noticeable physical and, in some cases, psychological symptoms. Here are common symptoms associated with Pectus Excavatum:

  • Visible Chest Deformity:
    • The most obvious symptom is the appearance of a sunken or caved-in chest. The sternum, the bone in the center of the chest, is displaced inward, giving the chest a concave or funnel-like shape.
  • Respiratory Symptoms:
    • In more severe cases, Pectus Excavatum can compress the lungs and affect respiratory function. This may lead to symptoms such as shortness of breath, especially during physical activities or exertion.
  • Cardiac Symptoms:
    • Compression of the chest wall can impact the position and function of the heart. This may result in palpitations (awareness of heartbeats) or, in rare cases, contribute to cardiac complications.
  • Exercise Intolerance:
    • Individuals with Pectus Excavatum, particularly those with moderate to severe cases, may experience difficulty participating in physical activities. Exercise intolerance can be a consequence of compromised respiratory and cardiovascular function.
  • Chest Pain or Discomfort:
    • Some individuals may experience chest pain or discomfort, especially during physical exertion or activities that put strain on the chest.
  • Poor Posture:
    • The chest deformity can affect posture, leading to slouching or other compensatory movements to conceal the sunken appearance. Poor posture can contribute to musculoskeletal issues.
  • Psychological Impact:
    • The visible nature of Pectus Excavatum may have psychological implications, particularly during adolescence when body image concerns are heightened. Individuals may experience self-esteem issues or feelings of self-consciousness.
  • Heart Murmurs:
    • In some cases, Pectus Excavatum may be associated with heart murmurs, abnormal heart sounds that can be detected during a medical examination.

Diagnosing Pectus Excavatum involves a combination of clinical evaluation, medical history assessment, and imaging studies. Here are the key components of the diagnostic process:

  • Physical Examination:
    • A healthcare professional will conduct a thorough physical examination, paying close attention to the chest wall, sternum, and ribcage. The characteristic sunken appearance of the chest is usually noticeable during this examination.
  • Medical History:
    • Gathering a detailed medical history is essential. The healthcare provider will inquire about any family history of Pectus Excavatum or other related conditions. They may also ask about the onset of symptoms and their progression.
  • Imaging Studies:
    • X-rays: X-rays are commonly used to visualize the chest and assess the severity of Pectus Excavatum. They provide a clear image of the chest’s bony structures, allowing healthcare professionals to measure the depth of the sternum’s indentation and evaluate the deformity.
    • CT Scans: In some cases, computed tomography (CT) scans may be recommended to provide a more detailed three-dimensional view of the chest wall. CT scans can help assess the impact of Pectus Excavatum on internal structures, such as the heart and lungs.
  • Functional Tests:
    • In cases where respiratory or cardiovascular symptoms are present, functional tests may be conducted. These can include pulmonary function tests (PFTs) to assess lung function and electrocardiograms (ECGs) to evaluate heart function.
  • Severity Assessment:
    • The severity of Pectus Excavatum is often measured using various indices, such as the Haller Index. This index is calculated based on the ratio of the transverse diameter of the chest to the anteroposterior diameter. A higher Haller Index indicates a more severe deformity.
  • Assessment of Symptoms:
    • The healthcare provider will inquire about any symptoms the individual may be experiencing, such as shortness of breath, chest pain, or exercise intolerance. This information is crucial for determining the appropriate course of treatment.
  • Multidisciplinary Evaluation:
    • In some cases, a multidisciplinary team, including pediatricians, pulmonologists, cardiologists, and surgeons, may collaborate to assess the condition comprehensively.

The treatment of Pectus Excavatum ( Funnel Chest ) depends on several factors, including the severity of the condition, the presence of symptoms, and the age of the individual. Treatment options range from observation and non-invasive methods to surgical interventions. Here are the main approaches to managing Pectus Excavatum:

  • Observation:
    • In mild cases of Pectus Excavatum without significant symptoms, observation and regular check-ups may be the recommended approach. The condition is monitored for any progression, and intervention may be considered if symptoms develop or worsen.
  • Physical Therapy:
    • Physical therapy and targeted exercises can be employed to improve posture and muscle strength. While this approach may not correct the deformity itself, it can help individuals manage symptoms and enhance overall physical well-being.
  • Bracing:
    • Bracing is a non-surgical option, typically used in younger individuals whose bones are still growing. Custom-made braces are designed to apply pressure to the chest, aiming to reshape the cartilage and bones gradually. Bracing is most effective in mild to moderate cases.
  • Minimally Invasive Techniques:
    • Vacuum Bell: This non-surgical device is placed over the chest and creates a vacuum, lifting the sternum and chest wall. It is used as a non-invasive method to reshape the chest gradually. Regular and prolonged use is required for noticeable effects.
  • Surgery – Nuss Procedure:
    • The Nuss procedure is a minimally invasive surgical technique for correcting Pectus Excavatum. It involves placing a curved metal bar beneath the sternum to push it into a more normal position. The bar is typically left in place for a few years before being removed.
  • Surgery – Ravitch Procedure:
    • The Ravitch procedure is a more traditional open-chest surgical approach. It involves removing a portion of the deformed cartilage and repositioning the sternum. While it is effective, it generally requires a longer recovery period compared to the Nuss procedure.
  • Hybrid Approaches:
    • Some surgeons may use a combination of techniques or modifications to the traditional procedures based on the individual’s anatomy and the severity of the deformity.
  • Postoperative Management:
    • Following surgery, individuals will need postoperative care, including pain management, monitoring for complications, and participation in rehabilitation exercises to promote a full recovery.
