Results: Six patients (three males and three females) were included in the study. There were three patients with congenital pulmonary airway malformation, two with pulmonary sequestration, and one with lung abscess; of these six patients, two had pectus excavatum. For surgery, four patients underwent lobectomy, one patient underwent segmental resection, and one patient underwent pulmonary segmentectomy. In both patients who had pectus excavatum complications, sternum elevation was not conducted at the same time. Although no significant differences in postoperative thoracic cavity deformation were observed, the lateral deviation tended to be small and the craniocaudal deformation tended to be large in patients with pectus excavatum. Postoperative chest CT scans showed mild improvements in the sternum in both patients.
