MODIFIED SANDWICH TECHNIQUE FOR ASYMMETRIC PECTUS CARINATUM AND EXCAVATUM–CARINATUM COMPLEX: A RETROSPECTIVE COHORT STUDY

jpedsurg.org

Asymmetric pectus carinatum (PC) and excavatum–carinatum complex (ECC) represent challenging chest wall deformities in which conventional bracing or single-direction minimally invasive techniques may fail to achieve satisfactory correction. The modified sandwich technique allows multidirectional remodeling of the anterior chest wall using combined internal and external bar placement; however, technical aspects such as bar number, length, placement sequence, and fixation remain insufficiently defined.

In brief

This retrospective study examines a modified sandwich technique for correcting complex asymmetric chest wall deformities that resist standard bracing or single-approach surgery. The method combines internal and external bar placement to achieve multidirectional remodeling in challenging pectus carinatum and mixed excavatum-carinatum cases.

Asymmetric PC and ECC often fail conventional bracing or single-direction minimally invasive repair techniques.
Modified sandwich technique uses combined internal and external bars for multidirectional chest wall remodeling.
Technical variables (bar number, length, placement sequence, fixation) require further standardization for optimal outcomes.
