Costal arch deformity is a relatively common thoracic wall malformation that can occur either alone or in combination with other deformities. It most commonly presents as a protrusion at the costal arch, with less frequent cases of depression or combined deformities involving both protrusions and depressions.
Introduction
Causes
The cause of primary costal arch protrusion deformity is unclear. Secondary costal arch protrusion deformity, however, has clear causes and is commonly seen in adult patients who have undergone pectus eacavatum surgery and in young children with severe abdominal distension, resembling a frog’s belly.
Symptoms
Apart from the abnormal appearance, patients with costal arch deformity typically do not have significant symptoms. However, many are troubled by their appearance and feel inferior, even leading to various psychological health issues.
