Vacuum Bell Therapy For Pectus Excavatum

Pectus excavatum, often referred to as sunken chest or funnel chest, is a congenital chest wall deformity characterized by a depression of the sternum and rib cage. While many individuals with mild cases may not experience significant health issues, severe pectus excavatum can lead to cardiopulmonary complications, body image concerns, and reduced exercise tolerance. Fortunately, advancements in medical technology have introduced non-surgical treatments like vacuum bell therapy, offering a promising alternative to invasive procedures. This comprehensive guide delves into the intricacies of vacuum bell therapy, its mechanism, benefits, procedure, ideal candidates, and what to expect during and after treatment.

Understanding Pectus Excavatum and Its Impact

Pectus excavatum is the most common congenital chest wall deformity, occurring in approximately 1 in 300 to 400 births. The condition is more prevalent in males than females and often becomes more noticeable during adolescence. The exact cause of pectus excavatum remains unclear, but it is believed to be related to abnormal growth of the costal cartilage that connects the ribs to the sternum.

The severity of pectus excavatum can vary widely. Mild cases may only present cosmetic concerns, while severe cases can compress the heart and lungs, leading to:

Cardiopulmonary Compromise: The sunken sternum can restrict the heart's ability to fill properly, reducing cardiac output and causing shortness of breath, chest pain, and fatigue, especially during physical exertion. Lung capacity may also be diminished, further contributing to respiratory difficulties.
Psychological Impact: The visible chest deformity can lead to significant body image issues, low self-esteem, anxiety, and social isolation, particularly during adolescence when body consciousness is heightened.
Postural Problems: Individuals with pectus excavatum may develop poor posture to compensate for the chest deformity, leading to back pain and other musculoskeletal issues.

Introduction to Vacuum Bell Therapy

Vacuum bell therapy is a non-surgical treatment option for pectus excavatum that utilizes negative pressure to gradually lift the sternum and reshape the chest wall. The device consists of a bell-shaped suction cup connected to a hand pump or electronic pump. The cup is placed over the sternal depression, and air is pumped out to create a vacuum, which gently pulls the sternum forward.

The vacuum bell was first introduced in the early 2000s and has since gained popularity as a safe and effective alternative to surgery for many individuals with pectus excavatum. It is particularly beneficial for younger patients with more flexible chest walls, but adults can also benefit from the therapy.

How Vacuum Bell Therapy Works: The Science Behind the Suction

The effectiveness of vacuum bell therapy lies in its ability to apply consistent, localized negative pressure to the chest wall. This negative pressure creates a gentle pulling force that gradually lifts the sternum and stretches the surrounding tissues, including the costal cartilage and ligaments.

Here's a breakdown of the mechanism of action:

Mechanical Traction: The vacuum bell creates a mechanical force that directly lifts the sternum. This force is distributed over a larger area compared to surgical techniques, minimizing the risk of localized tissue damage.
Cartilage Remodeling: The costal cartilage is a flexible tissue that can be reshaped over time with consistent pressure. The vacuum bell promotes cartilage remodeling by stimulating the growth of new cartilage cells and altering the alignment of existing cells.
Soft Tissue Adaptation: The surrounding soft tissues, including muscles, ligaments, and fascia, also adapt to the lifting force. This helps to maintain the corrected position of the sternum and prevent relapse.
Improved Blood Flow: The negative pressure created by the vacuum bell can improve blood flow to the chest wall, which may promote tissue healing and regeneration.

Benefits of Vacuum Bell Therapy Compared to Surgery

Vacuum bell therapy offers several advantages over surgical correction of pectus excavatum, primarily the Nuss procedure or Ravitch technique:

Non-Invasive: Vacuum bell therapy is a completely non-surgical approach, eliminating the risks associated with anesthesia, incisions, and chest tube placement.
Reduced Pain: Patients typically experience minimal discomfort during vacuum bell therapy, compared to the significant post-operative pain associated with surgical procedures.
Shorter Recovery Time: There is no recovery period required after each vacuum bell session. Patients can immediately return to their normal activities. Surgical procedures, on the other hand, require weeks or months of recovery.
Lower Risk of Complications: Vacuum bell therapy has a lower risk of complications compared to surgery, such as infection, bleeding, pneumothorax (collapsed lung), and cardiac injury.
Cosmetic Improvement: In addition to correcting the chest deformity, vacuum bell therapy can improve the overall appearance of the chest wall, leading to increased self-esteem and body image.
Cost-Effective: Vacuum bell therapy is generally less expensive than surgical correction, considering the costs of surgery, anesthesia, hospitalization, and post-operative care.

Who is a Good Candidate for Vacuum Bell Therapy?

While vacuum bell therapy is a promising treatment option, it is not suitable for everyone with pectus excavatum. Ideal candidates typically include:

Younger Patients: Children and adolescents with more flexible chest walls tend to respond better to vacuum bell therapy. The younger the patient, the more pliable the cartilage, and the faster the results are likely to be.
Mild to Moderate Pectus Excavatum: Vacuum bell therapy is most effective for individuals with mild to moderate pectus excavatum. Severe cases may require surgical intervention.
Flexible Chest Wall: The chest wall should be relatively flexible and able to be lifted with suction. Patients with very rigid chest walls may not experience significant improvement with vacuum bell therapy.
Motivated and Compliant Patients: Vacuum bell therapy requires consistent and diligent use. Patients must be motivated to adhere to the prescribed treatment schedule to achieve optimal results.
No Prior Chest Surgery: Patients who have undergone previous chest surgery may not be suitable candidates for vacuum bell therapy due to scar tissue and altered chest wall mechanics.
Absence of Underlying Medical Conditions: Certain medical conditions, such as connective tissue disorders or bleeding disorders, may contraindicate vacuum bell therapy.

A thorough evaluation by a qualified medical professional, such as a pediatric surgeon or pulmonologist, is necessary to determine if vacuum bell therapy is the right treatment option for an individual with pectus excavatum.

The Vacuum Bell Therapy Procedure: A Step-by-Step Guide

The vacuum bell therapy procedure is relatively straightforward and can be performed at home under the guidance of a healthcare professional. Here's a detailed step-by-step guide:

Initial Assessment: The healthcare provider will assess the severity of the pectus excavatum, evaluate the flexibility of the chest wall, and determine the appropriate size and shape of the vacuum bell.
Preparation: Before each session, the skin on the chest should be clean and dry. Some patients may benefit from applying a small amount of lotion or cream to the skin to improve the seal of the vacuum bell.
Placement: The vacuum bell is placed over the deepest part of the sternal depression. It is important to ensure that the bell is centered and that the edges are in full contact with the skin to create a good seal.
Creating the Vacuum: Using the hand pump or electronic pump, air is gradually removed from the bell to create a vacuum. The amount of suction should be increased gradually until the sternum is lifted to the desired position.
Monitoring and Adjustment: During the session, the patient should be monitored for any signs of discomfort or skin irritation. The amount of suction may need to be adjusted based on the patient's tolerance and the response of the chest wall.
Duration and Frequency: The duration and frequency of vacuum bell therapy sessions vary depending on the individual's age, severity of pectus excavatum, and response to treatment. Typically, patients start with shorter sessions (e.g., 30 minutes) and gradually increase the duration to several hours per day. The bell is generally worn daily.
Removal: To remove the vacuum bell, air is slowly allowed back into the bell to release the suction. The bell can then be gently lifted off the chest.

What to Expect During and After Vacuum Bell Therapy

During vacuum bell therapy, patients may experience some mild discomfort or a pulling sensation in the chest. This is normal and usually subsides as the body adapts to the pressure. Some patients may also experience temporary skin redness or bruising under the bell.

After each session, it is important to moisturize the skin to prevent dryness and irritation. Patients should also avoid activities that put excessive strain on the chest wall, such as heavy lifting or strenuous exercise.

It is crucial to maintain regular follow-up appointments with the healthcare provider to monitor progress, adjust the treatment plan as needed, and address any concerns.

Long-Term Outcomes and Maintenance

The long-term outcomes of vacuum bell therapy depend on several factors, including the patient's age, severity of pectus excavatum, compliance with treatment, and individual response. In general, patients who start vacuum bell therapy at a younger age and adhere to the prescribed treatment schedule tend to achieve the best results.

While vacuum bell therapy can significantly improve the appearance of the chest wall and alleviate associated symptoms, it is important to understand that it may not completely correct the deformity in all cases. Some patients may require maintenance therapy to prevent relapse. This may involve wearing the vacuum bell for shorter periods of time or on an intermittent basis.

Potential Risks and Side Effects

Vacuum bell therapy is generally considered a safe treatment option, but like any medical procedure, it carries some potential risks and side effects:

Skin Irritation: Redness, bruising, and blisters can occur under the vacuum bell due to the suction pressure. These skin irritations are usually mild and resolve on their own with proper skin care.
Pain or Discomfort: Some patients may experience mild pain or discomfort during vacuum bell therapy. This can usually be managed with over-the-counter pain relievers.
Paradoxical Chest Wall Movement: In rare cases, the chest wall may move inward during vacuum bell therapy instead of outward. This is known as paradoxical chest wall movement and may require adjustment of the treatment plan.
Pneumothorax: Although extremely rare, pneumothorax (collapsed lung) is a potential complication of vacuum bell therapy. This is more likely to occur in patients with underlying lung disease.
Relapse: There is a risk of relapse after discontinuing vacuum bell therapy, especially if the treatment is stopped prematurely. Maintenance therapy may be necessary to prevent relapse.

It is important to discuss these potential risks and side effects with the healthcare provider before starting vacuum bell therapy.

The Psychological Aspect of Pectus Excavatum and the Role of Vacuum Bell Therapy

Beyond the physical implications, pectus excavatum often has a significant psychological impact on individuals, particularly adolescents. The visible chest deformity can lead to:

Body Image Issues: The sunken chest can cause feelings of self-consciousness, embarrassment, and dissatisfaction with one's appearance.
Low Self-Esteem: Individuals with pectus excavatum may develop low self-esteem and lack confidence due to their perceived physical imperfection.
Social Anxiety: The fear of being judged or ridiculed can lead to social anxiety and avoidance of social situations, such as swimming or changing in public.
Depression: In severe cases, the psychological distress associated with pectus excavatum can contribute to depression and other mental health issues.

Vacuum bell therapy can play a crucial role in addressing these psychological concerns by improving the appearance of the chest wall and boosting self-confidence. As the sternum is gradually lifted, individuals may experience a significant improvement in their body image, self-esteem, and overall quality of life. The non-invasive nature of vacuum bell therapy can also be appealing to those who are hesitant to undergo surgery.
