Chest Deformities: Symptoms, Diagnosis, and Treatment Methods

Chest deformities occur when the cartilage and bone structures forming the rib cage develop abnormally in the womb or during childhood, causing the chest to cave in or protrude outward. The most commonly known types are colloquially called funnel chest and pigeon chest. These rib cage anomalies are not just aesthetic concerns affecting physical appearance; they can also press against the heart and lungs, leading to serious health issues like shortness of breath, rapid fatigue, and chest pain. Especially during the rapid growth spurts of adolescence, these structural changes become more pronounced and can deeply affect a young person's psychological and social development. Thanks to early diagnosis and proper treatment planning, it is possible to restore the normal anatomical structure of the chest wall using both surgical and non-surgical methods.

• The most common types are Pectus Excavatum, characterized by an inward depression, and Pectus Carinatum, known for outward protrusion.
• In suitable patients, non-surgical methods such as the vacuum bell, custom-made braces (orthoses), and specific bandaging yield successful results.
• For surgical treatment, minimally invasive (closed) techniques like the Nuss and Abramson procedures are generally preferred.
• The ideal time for surgical intervention in children is usually between 5 and 8 years of age, though it can be performed earlier if medically necessary.
• Advanced deformities can compress the heart and lungs, reducing exercise capacity and causing shortness of breath.
• Untreated cases often pave the way for serious psychosocial problems, such as withdrawal and a lack of self-confidence.

What Are Chest Deformities and What Are Their Types?

The rib cage acts as a vital shield protecting our heart, lungs, and major blood vessels. Chest deformities are structural anomalies resulting from the abnormal growth of the sternum (commonly known as the breastbone) and the attached rib cartilage that make up the front of this shield. This condition is usually congenital but often goes unnoticed during early childhood, becoming prominent during the rapid growth spurts of puberty. These structural abnormalities, which are quite common in society, are named differently depending on the direction in which the anatomical structure is distorted.

What is Funnel Chest (Pectus Excavatum)?

The clearest answer to what pectus excavatum is lies in its appearance: the middle part of the rib cage, specifically the breastbone, is sunken inward toward the spine. It is the most common chest wall deformity and is seen in boys about four times more often than in girls. The depth of the depression varies greatly from patient to patient. In some cases, it is only noticed as a slight dimple, while in severe cases, the breastbone may sink so deeply that it almost touches the spine. This deep depression can push the heart to the left side and prevent the lungs from expanding to their full capacity.

What is Pigeon Chest (Pectus Carinatum)?

Pectus carinatum is a condition where the breastbone and rib cartilage protrude outward, creating a pointed appearance. Because it resembles the chest structure of birds, it is commonly referred to as pigeon chest. It is usually noticed towards the end of childhood or during puberty. Although not as common as pectus excavatum, it can make patients quite uncomfortable aesthetically and psychologically, especially since it is often visible under clothing.

Other Chest Wall Anomalies

Aside from these two main types, there are rarer deformities. Poland Syndrome, characterized by the unilateral absence of the chest muscle and hand anomalies; Pectus Arcuatum, where the upper part of the breastbone protrudes outward while the lower part curves inward; Sternal Cleft, a condition where the breastbone is split down the middle; and Rib Flare, where the lower ribs curve outward, are other conditions monitored and treated by specialist physicians.

Causes and Risk Factors of Rib Cage Anomalies

Although the exact cause of chest deformities has not been fully illuminated in the medical world, it is known that genetic predisposition plays a very strong role. About forty percent of patients have a family history of a similar chest wall anomaly. The excessive and uncontrolled growth of cartilage tissue causes the ribs to pull the sternum inward or push it outward.

Connective tissue disorders are also a significant risk factor. Chest deformities are much more common in individuals with genetic connective tissue diseases such as Marfan syndrome and Ehlers-Danlos syndrome. Additionally, in patients with scoliosis (spinal curvature), chest cage asymmetry and deformities can occur simultaneously. Rapid height growth and bone development during puberty are the most critical triggers that can suddenly increase the severity of the deformity. For this reason, a mild depression or protrusion during childhood can suddenly worsen between the ages of 12 and 15.

What Are the Symptoms of Chest Deformities?

Symptoms vary greatly depending on the severity of the deformity and the patient's age. While mild cases may not present physical complaints, the primary issue is visual asymmetry. However, as the deformity progresses, both physical and psychological symptoms are added to the clinical picture.

Among the physical symptoms, the most common is shortness of breath during exertion. Due to the pressure on the heart and lungs, patients tire much faster than their peers while playing sports. Palpitations, chest pain, recurrent respiratory tract infections, and asthma-like wheezing are other physical findings. Structural abnormalities in the chest area can sometimes cause breast tissue to appear asymmetrical; while this may worry patients, it should not be confused with breast cancer symptoms, as it is a completely different anatomical issue.

Psychosocial symptoms are often overlooked but deeply affect the patient's life. Because chest wall deformities cause a significant aesthetic irregularity, patients frequently complain about their appearance. Activities like going to the sea or pool in the summer, or changing into uniforms for physical education classes, become major sources of stress for teenagers. To hide this stress, patients often adopt a slouched posture by dropping their shoulders forward. They generally tend to feel shy, withdrawn, and isolated.

How is it Diagnosed at the Hospital?

Diagnosing chest deformities begins with a detailed physical examination by a specialist physician. The doctor evaluates the structure of the rib cage, whether the depression or protrusion is symmetrical, and the patient's posture. However, merely looking from the outside is not enough to understand the degree of pressure on the internal organs. At this stage, radiological imaging methods come into play.

A two-way chest X-ray is the first step to seeing the general condition of the rib cage. For a more detailed examination, a Computed Tomography (CT) scan is performed. A specific measurement called the Haller Index is calculated using the CT images. This index is obtained by dividing the width of the rib cage by the distance between the sternum and the spine. The resulting value is the gold standard for determining the severity of the deformity and the necessity of surgery.

Additionally, an Echocardiography (ECHO) is requested to evaluate the structural and functional state of the heart, and Pulmonary Function Tests (PFT) are used to measure lung capacity. These tests clearly reveal the damage the deformity may be causing to vital organs.

Treatment Methods for Chest Deformities

Once diagnosed, the most appropriate treatment plan is determined based on the patient's age, the type and severity of the deformity, and their psychological state. Minimally invasive (closed) techniques and non-surgical treatment options are always evaluated before considering open surgery.

What Are the Non-Surgical Treatment Methods?

When deemed appropriate by a specialist, non-surgical methods initiated at an early age yield highly gratifying results. The Vacuum Bell system, developed for the treatment of funnel chest, applies external negative pressure to the chest wall, gradually pulling the sunken breastbone upward. The vacuum system is a bell-shaped medical device made of silicone. Using a pump on the device, the air inside is evacuated to create a negative pressure. Requiring regular and patient use, this method is an excellent alternative for patients who do not wish to undergo surgery.

In pectus carinatum cases, a custom-made brace (orthosis) treatment is applied. This brace applies continuous, gentle pressure to the protruding bone, allowing it to return to its normal position over time. For rib flare treatment, specific bandaging techniques are used. In addition to all these methods, posture exercises to correct the patient's posture and breathing exercises to increase lung capacity are integral parts of the treatment program.

Surgical Treatment: Closed and Open Surgeries

When non-surgical methods are insufficient or the deformity is very advanced, surgical intervention is considered. Closed surgical techniques are the first choice because they speed up the patient's recovery process. The most commonly used method for pectus excavatum is the Nuss Procedure. During the surgery, performed under general anesthesia, a curved steel or titanium bar is placed under the sunken bone via small incisions on both sides of the rib cage, guided by a camera. This bar pushes the bone outward, providing immediate correction. For pigeon chest surgery, the Abramson Procedure is applied; here, the bar is placed under the skin to press the protruding bone inward.

In surgeries performed using the Nuss and Abramson methods, patients are usually discharged after a few days in the hospital and can return to their normal lives after one week. In the future, there are no issues with them playing sports or fulfilling military service. The implanted bars usually remain in the body for 2 to 4 years and are then removed with a simple procedure.

Open Surgery (the Ravitch procedure) may be preferred, especially in complex cases with highly asymmetrical, severe deformities, chondromanubrial deformities, or severe compression on the lungs or heart. The most appropriate age range for surgery in children is generally between 5 and 8 years; however, in cases where cardiopulmonary dysfunction is detected, intervention can be performed at an earlier age.

Complications and Risk Groups

When chest deformities are left untreated, complaints become more severe as the rib cage loses its flexibility with advancing age. Constant pressure on the heart and lungs can pave the way for rhythm disorders, heart valve problems, and chronic respiratory failure in later years. The structural narrowing in the rib cage can also affect intra-abdominal pressure, indirectly impacting the digestive system; patients may sometimes experience complaints such as bloating after eating in addition to shortness of breath.

One of the biggest risk groups is adolescents. Deformities left untreated during this period can lead to severe psychiatric complications such as deep depression, social isolation, and body dysmorphic disorder. As with any surgery, surgical treatments carry rare risks such as infection, bleeding, or the shifting of the implanted bar. However, when performed by experienced surgeons in fully equipped hospitals, these risks are minimal.

When to See a Doctor?

Structural abnormalities in the rib cage are usually noticed by parents during childhood. If you observe the following situations, it is recommended that you consult a specialist without delay:

• If you notice a distinct depression or outward protrusion in the middle of your child's chest,
• If a mild structural abnormality suddenly deepens during puberty,
• If your child gets out of breath very quickly while playing with peers or doing sports,
• If physical and psychological symptoms such as poor posture, slouched shoulders, and withdrawal have begun, you should consult a doctor.

If the patient experiences emergency symptoms such as sudden severe chest pain, shortness of breath that does not go away with rest, bluish lips, or fainting (syncope) during exertion, you should immediately call 112 for emergency services or visit the nearest hospital's emergency room.

Following stabilization in the emergency room, permanent treatment processes are planned by the relevant surgical departments. When applying to our hospital, bringing your previous X-ray, CT, and ECHO results with you will speed up the process.

Frequently Asked Questions

Do chest deformities correct themselves?

No, these anatomical anomalies in the cartilage and bone structure do not correct themselves or improve over time. On the contrary, the degree of the deformity tends to increase, especially during the rapid growth phase of puberty. Exercises started early only support posture; they do not change the bone structure.

At what age should surgery be performed?

The most appropriate time for surgical intervention in children is generally between 5 and 8 years of age, when the flexibility of the rib cage is high. However, if a severe deterioration in the patient's heart and lung functions is detected, surgery can be planned at an earlier age. Surgery is also possible in adulthood, but the recovery process may take a little longer as bone flexibility decreases.

Is pigeon chest surgery risky?

Closed (Abramson) pigeon chest surgery, performed with current medical approaches, carries a much lower risk compared to traditional open surgeries. The amount of bleeding is minimal, the hospital stay is short, and recovery is quite fast. When performed by an experienced surgical team, the success rate is extremely high.

Do braces or vacuum bells work for funnel chest treatment?

Yes, when suitable patients are selected, non-surgical methods are highly effective. A vacuum bell is used for funnel chest, and special orthotic braces are used for pigeon chest. Using these devices patiently, for the duration and frequency recommended by the physician, is critically important for the success of the treatment.

Can I play sports after surgery?

About a month after closed surgeries, you can start light-paced walking, and from the sixth week, you can begin sports that support chest muscles, such as swimming. It is generally recommended to pause heavy contact sports where the rib cage could take a direct hit until the bar is removed.
