Article overview

What is a keel breast?

A keel chest (pectus carinatum) is a keel-shaped deformation of the breastbone. It is the 2nd most common congenital condition in childhood. Doctors differentiate between a symmetrical and an asymmetrical form of keel chest:

  • In the symmetrical keel chest, both sides of the breastbone bulge out evenly.
  • In asymmetrical keel breasts, on the other hand, the bulge is more pronounced on one side. It is even possible that one of the two sides is hardly affected or not affected at all.

Causes of a keel chest

The exact reasons for the occurrence of pectus carinatum (medical term for keel chest) are controversial. However, there is a generally accepted explanation. This states that the keel chest is caused by excessive growth of the cartilage connections in the chest area (connections between the breastbone and ribs).

Only in rare cases is a predisposition to a keel chest present at birth. In most cases, the funnel chest develops during the growth phase in childhood. The deformity also appears to occur more frequently in certain families. However, scientists have not yet been able to determine an exact hereditary pathway. Boys are more frequently affected than girls.

In some cases, the keel chest occurs as a concomitant symptom of another disease. The following primary diseases can cause the breast area to bulge:

  • Mucopolysaccharidosis
  • Thoracic emphysema
  • Marfan syndrome
  • Scoliosis

Symptoms of a keel chest

Patients with a keel chest are often psychologically burdened by their physical deformity. Teasing or strange looks are the order of the day for them. Kiel breasts therefore often have a negative effect on patients' self-esteem and self-satisfaction. The psychological stress is usually the reason why those affected consult a doctor.

However, medical problems can also arise in connection with pectus carinatum. Some patients are unable to sleep because of the pain. Abdominal sleepers in particular wake up several times a night because of the pain.

They are usually given painkillers so that they can sleep through the night again. Pain can also be caused by localized trauma to the sternum.

Treatment of a keel chest

The following treatments are possible for a keel chest:

  • Conservative: doctors use a pressure bandage (pad) in children.
  • Open surgery: After the end of puberty, those affected can have keel-breast surgery.
  • Minimally invasive: Alternatively, patients can opt for the MIPCR (Minimally Invasive Pectus Carinatum Repair) procedure. In the MICPR procedure, doctors implant a metal bar that pushes the keel down.

Conservative treatment of the keel breast

A pressure bandage (pad) is used as a conservative method, particularly in young patients who are still growing. The pad is a pressure bandage that is designed to press the sternum back into place by applying constant pressure from the outside.

This method can only be used if the chest area is not yet fully grown andfirm. Due to the constant pressure, the pad is associated with pain and discomfort.

Surgical treatment of the keel chest

Surgical treatment is carried out by keel chest specialists. Surgery is advisable if the chest can no longer be compressed. In other words, when the patient has reached the end of the pubertal growth phase.

During open surgery, doctors expose the chest wall to allow access to the cartilage connections. They then remove the cartilage connections and push the sternum back into its original position. Doctors fix and secure the sternum in its new position with metal implants.

Minimally invasive treatment of the keel breast

A minimally invasive alternative is the MIPCR (Minimally Invasive Pectus Carinatum Repair) procedure. In the MICPR procedure, the surgeon makes a longitudinal incision on both sides of the rib cage.

He then attaches stabilizers to the ribs and inserts a stirrup. The stirrups and stabilizers help to lift the curvature. However, not every keel chest is suitable for MIPCR. You should discuss whether you are suitable for a minimally invasive procedure with a keel-breast specialist.
