Surgical treatment of chest wall deformities is done with costal cartilage resection in selected patients in adolescence. In this study, we evaluated the effect of costal cartilage resections on the lung volume stereologically by using computed tomography. In this study, sixteen four weeks old New Zealand rabbits were used. Young subjects were preferred to evaluate the effect of the operation on the growth process. In order to avoid postoperative complications, only two costal cartilage resections were performed. In the surgical group the right 4th and 5th costal cartilages were resected (n=8). The group that was not operated was accepted as the control group (n=8). The growth of the subjects was followed. Computed thorax tomography (CTT) scans of all animals were performed preoperatively and at the 4th postoperative week. Estimation of pre- and postoperative lung volumes was performed with the Cavalieri’s principle. In the control group followed up during growth, bilateral lung volumes were increased (15.75% and 20.62% respectively right and left lungs). In the surgical group, both the surgical side and the opposite lung volume decreased after costal cartilage resection (20.09% and 1.07% respectively right and left lungs). Even though the number of resected cartilages was limited, total lung volume decreased after costal cartilage resection. In the treatment of chest wall deformities, costal cartilage resection should be considered as the last option in children.
