What is pectus excavatum?

Pectus excavatum is a chest wall deformity where the chest bone (sternum) is pushed inwards. This happens because of an overgrowth of cartilage between the ribs and the breastbone. This causes the sternum to appear sunken into the chest or dented.

It’s frequently diagnosed in older children and teenagers as it becomes noticeable during growth spurts in puberty.

It is not to be confused with pectus carinatum, when the breastbone sticks outward.

Symptoms

  • sunken sternum: a visual ‘dent’ in your chest
  • rib flaring: in some cases, your ribs may stick out
  • asymmetry: your chest shape may look uneven, with one side of the chest appearing more sunken than the other

It is possible to have a chest shape that has characteristics of both pectus carinatum and excavatum, where part of the chest protrudes whereas the other dents inwards.

The severity of the condition varies, and in rare cases, it may present alongside other disorders like Marfan syndrome or scoliosis.

Psychological impact

Patients can find the psychological distress of having a pectus deformity much worse than the physical symptoms. Many patients, especially teenagers, may worry about their appearance and about others noticing.

This can lead to:

  • social anxiety
  • body image issues
  • low confidence
  • low self-esteem
  • feeling more self-consciousness
  • withdrawal from activities you used to enjoy, for example swimming

A 2024 study showed that patients with pectus excavatum reported a decreased quality of life and depressive tendencies.

Other complications

Some people report secondary symptoms, including:

  • shortness of breath
  • reduced ability to exercise
  • decreased stamina
  • decreased endurance
  • heart palpitations

However symptoms can vary from person to person and not everyone may experience these.

Causes

The exact cause of pectus excavatum is unknown, but it’s thought to result from abnormal cartilage growth. Pectus excavatum tends to run in families, which suggests that genetics may play a role. It can also be linked to rare conditions like Marfan syndrome.

Diagnosis

Diagnosis usually starts with a physical examination, as the sunken chest is often visible. The severity of pectus excavatum is often measured using the Haller index, which assesses the depth of the chest’s inward curve.

To understand the severity and rule out other conditions, imaging tests like X-rays or CT scans may be recommended.

Treatment

Treatment options depend on these factors:

  • your age
  • the severity of your pectus excavatum
  • the flexibility of your chest

Non-surgical treatment

  • Vacuum bell therapy: a non-invasive option which involves applying a device with a silicone cup and vacuum pump (the vacuum bell) that gradually pulls the sternum outward and reshapes the chest.
  • Rib flaring brace: often used with the vacuum bell to correct rib flaring and improve chest shape.

Surgical treatment

  • Nuss procedure: also called the minimally invasive repair of pectus excavatum (MIRPE) is when a curved metal bar is inserted into the chest to push the sternum outward. A second surgery is then needed to remove the bar after several years.
  • Ravitch procedure: a more traditional surgery where the cartilage causing the depression is removed and the sternum is repositioned.

Non-surgical options are often effective for most cases, while surgery may be necessary for more severe cases or for those who do not want to commit to the vacuum bell treatment schedule.
