Summary

Pectus excavatum (funnel chest) is the most common congenital anterior thoracic wall deformity. It can be associated not only with cosmetic concerns but also with psychosocial and limiting somatic complaints. Patients with this condition are often treated surgically using the Nuss bar procedure, in which a metal bar is placed behind the sternum to effectively "pop out" the funnel chest. This bar typically remains in place for 2-3 years. To analyze how the thoracic wall changes after removal of the Nuss bar, we aim to capture three-dimensional (3D) images at four different time points: just before removal, immediately after, and at 6 and 12 months post-removal. When significant changes over time are detected, we aim to identify factors that may predict retraction or recurrence. Based on these predictive factors, individualized decision-making regarding the timing of Nuss bar removal can be optimized to minimize the risk of retraction or recurrence.
