Surgical correction of pectus carinatum.
Pectus carinatum is an infrequent but eminently correctable chest wall deformity. It is encountered much less frequently than pectus excavatum. In 12 years, from 1973 to 1985, 152 pectus carinatum (16.7%) and 758 pectus excavatum deformities (83.3%) were corrected. It occurs more frequently in boys (119 patients) than girls (33 patients). The majority, 89 cases, were symmetric, while 49 were asymmetric, and 14 were mixed deformities (ipsilateral carinatum, contralateral excavatum). In almost half the patients the deformity was not identified until after the 11th birthday. A family history of chest wall deformities was present in 26%, and of scoliosis in 12%. Associated musculoskeletal abnormalities were identified in 34 patients (scoliosis 23, Poland's syndrome 4, neurofibromatosis 2, Morquio's disease 2, vertebral anomalies 1, hyperlordosis 1, and kyphosis 1). Surgical correction required bilateral resection of the third through seventh costal cartilages in 143 patients, and unilateral resection in nine patients with an isolated abnormality. A single osteotomy was used in 88 patients and a double osteotomy in 53 patients. In 11 cases no osteotomy was required. Mixed deformity with posterior angulation of the sternum was managed by osteotomy and anterior displacement. The remaining cases had sternal osteotomy and fracture of the posterior cortex to correct anterior angulation. The operation was completed with a low complication rate 3.9% (pneumothorax 4, wound infection 1, atelectasis 1, and local tissue necrosis 1). Three patients required revision with additional unilateral lower cartilage resection for persistent malformation of the costal arch. All patients ultimately had a satisfactory result.
