Abstract
Pectus carinatum is an uncommon malformation that is often more symptomatic than the appearance suggests, and one that physicians often do not refer for surgical correction. Hospital records of 90 patients who underwent repair of pectus carinatum deformities between 1970 and 2000 were reviewed. During the same period another 445 patients underwent repair of excavatum deformities. Minimal deformity was observed before the age of 10 years for 81 of 90 patients; only 7 of the 90 underwent repair before age 11 years. AH patients were symptomatic; 84 had exertional dyspnea and exercise limitation, 52 had frequent respiratory infections, 24 had asthma, and 38 had chest discomfort. The mean pectus severity score (width of chest divided by the distance between the sternum and spine) was 1.73 (the normal chest is 2.56). The type of repair varied with the type of deformity, consisting of subperiosteal resection of the deformed cartilages, transverse osteotomy of the anterior sternum with insertion of a cartilage wedge, and support with a steel strut for 4 to 6 months in 76 of 90. There were no deaths within 1 year after the repair. Complications included hypertrophic scar (n=13), wound seroma (n=5), pleural effusion (n=3), and pneumothorax (n=2). The mean blood loss was 78 ml, and the mean hospital stay was 2.6 days. With a mean follow‐up of 12.8 years, all patients experienced alleviation of respiratory symptoms and chest discomfort and diminished exercise limitation; 88 of 90 patients experienced a very good to excellent long‐term result. One patient required reoperation. Pectus carinatum often causes more severe respiratory symptoms and exercise limitation than is generally recognized. Repair in 90 patients with carinatum deformities has resulted in marked clinical improvement in all patients, with low morbidity and short hospitalization.
