Pectus excavatum

From WikiMD's Wellnesspedia

Pectus excavatum, also known as "funnel chest" or "sunken chest", is a congenital chest wall deformity characterized by a concave, or caved-in, appearance of the sternum. The severity of the condition varies between individuals, and it can range from a mild indentation to a severe depression, potentially impacting surrounding organs.

Pathophysiology[edit | edit source]

Pectus excavatum results from an excessive growth and abnormal orientation of the costal cartilages, leading to the depression of the sternum. This growth disturbance is usually noted in the first year of life and becomes more pronounced during the rapid growth period of puberty. Although the exact cause is not known, it is believed to have a genetic component, as it frequently occurs in families and is often associated with other genetic disorders such as Marfan syndrome and Ehlers-Danlos syndrome.

Clinical Presentation[edit | edit source]

Clinically, the hallmark of pectus excavatum is a visibly sunken sternum, which can become more pronounced with growth or physical activity. The condition may cause discomfort or pain in the chest and back, and it may also affect respiratory function in severe cases, leading to shortness of breath, especially during physical activity. It is also common for individuals with pectus excavatum to experience feelings of self-consciousness due to the appearance of their chest.

Diagnosis[edit | edit source]

Diagnosis of pectus excavatum is typically made based on physical examination. Imaging studies, such as chest X-rays, CT scans, or MRI, may be used to assess the severity of the depression and its effect on the heart and lungs. Pulmonary function tests may also be performed to evaluate any breathing difficulties.

Management and Treatment[edit | edit source]

The management of pectus excavatum depends on the severity of the symptoms and the impact on the patient's quality of life. Mild cases without significant symptoms or functional impairment may not require any specific treatment except for regular monitoring.

For moderate to severe cases, surgical correction may be recommended. The most common procedure is the Nuss procedure, a minimally invasive approach that involves the insertion of a curved metal bar to correct the shape of the sternum. Postoperative pain management is an essential part of the recovery process.

Physical therapy exercises may also help to improve posture, increase lung capacity, and strengthen chest wall muscles.
