Chest wall deformities and spinal deformities are seen in children and adults with congenital diaphragmatic hernia. Thoracic asymmetry is present in 48% of adults with congenital diaphragmatic hernia, 18% have a funnel chest, and 27% have significant scoliosis with a Cobb angle greater than 10°. The incidence of these deformities was highest in those patients with large diaphragmatic defects who underwent open-heart or open-heart surgery. It is possible that there is some tension in the repair of the huge defect, which may affect the normal development of the thorax and cause thoracic asymmetry. Some authors have reported a lower incidence of chest wall and spinal deformities, but in these reports, the follow-up was shorter. Clearly, these deformities should be monitored in survivors of congenital diaphragmatic hernia. In another study conducted from January 2004-December 2009, the aim was to determine the age (in months) of occurrence of funnel chest after diaphragmatic hernia repair. During this period, 40 children with diaphragmatic hernia were followed up. Of these, 4 (10%) developed a funnel chest at 6 months after diaphragmatic hernia repair, while 25% (9) developed a funnel chest deformity at 12 months after surgery and 36% (9) of the children developed this deformity at 24 months after surgery. Not all children need surgery. In older children some physical exercises may be used for clinical observation, while in younger children physiotherapy is used and observed. In terms of etiopathogenesis, this interrelationship between diaphragmatic hernia and funnel chest may be due to the following factors: (1) hypertonicity during diaphragmatic repair; (2) decreased elasticity of the thorax after the use of Goretex patches; (3) open thoracotomy during diaphragmatic repair; and (4) ipsilateral thoracic dysplasia secondary to unilateral pulmonary dysplasia. Funnel chest with diaphragmatic hernia is difficult to identify lung disease and rib sternal malformation symptomatically. However, unlike the primary funnel chest, this presents later and generally has a better outcome without surgery. Like many authors, we recommend planned physical exercise and postural correction for patients with minor deformities, hopefully avoiding invasive surgery.
