[Malformations of the anterior chest wall].
BACKGROUND
Pectus excavatum or funnel chest is the most common anterior chest wall deformity seen in children and adults. The sternal depression appears to be caused by overgrowth of the costal cartilages, also the cause of the less common deformities: pectus carinatum (pigeon breast) and pectus arcuatum.


BACKGROUND
Usually the overgrowth involves the third to seventh costal cartilages but it can be more or less extensive. The cardiopulmonary functional consequences are insignificant in the protrusional deformities and inconsistent in pectus excavatum and the indications for surgery are mainly cosmetic.


CONCLUSIONS
The procedural modalities are guided by morphological study of the CT scan. We describe a surgical technique that comprise subperichondrial excision of all deformed costal cartilages followed by transverse sternotomy to correct the sternal deformity, anteriorly in the case of pectus excavatum and posteriorly for pectus carinatum and arcuatum. As the perichondrial sheaths are totally preserved they are sutured in continuous layers to give a shortening effect. In the case of pectus excavatum the sternum is then secured anteriorly for about 6 months by a retrosternal metallic strut in an overcorrected position. The partially resected seventh cartilages are then sutured to the xiphoid. Other surgical techniques are described, including modified Ravitch's procedure, modelling osteochondroplasty, prosthetic reconstruction and Nuss's procedure. Results of the more important series are reported and discussed.
