correct answer
b Hybrid Ravitch/Nuss procedure

This patient has pectus arcuatum. The pathoanatomy of this chest wall deformity involves premature obliteration of the sternal sutures or congenital non-segmentation of the sternum, which results in angulation of the bone. This is distinct from both pectus carinatum and excavatum, where aberrant cartilage growth leads to an increase or decrease, respectively, in the AP diameter of the chest. Although similar in appearance, pectus arcuatum also differs from "mixed" pectus lesions, which result from abnormal cartilage development that leads to simultaneous protrusion and depression of the sternum. Bracing and/or vacuum bell therapy is not effective in pectus arcuatum. A hybrid surgical approach, consisting of a transverse incision, subperichondrial resections of upper costal cartilages, a sternal osteotomy and a low-placed Nuss bar, is a good option for definitive correction with minimal morbidity and high patient satisfaction. Another procedure with a vertical incision, subperichondrial cartilage resections, one or more sternal osteotomies and sternal plating is also effective. Sternal rotation would not be helpful with this pathology.
