To explain: The range and eligibility for new minimally invasive, prosthetic and operative procedures that are available for pectus deformity repair. The CT anatomic features that direct the correct surgery selection and predict successful physiologic and cosmetic outcome. Essential pre-operative features that must be elicited by CT technique

Anatomy: symmetric/asymmetric pectus variants Indications/eligibility for repair Operative options: Minimally invasive (e.g. endoscopic Nuss), thoracotomy (e.g. costal cartilage and sternal realignment techniques). CT technique (e.g. Dual energy, coverage, contrast); CT parameters (e.g. Haller index, sternal tilt, costal symmetry and flare) 3-D rendering techniques (e.g. demonstrating unossified cartilage) “Real world” techniques (e.g. CT data-derived stereolithography, modelling)

The major teaching points of this exhibit are: New pectus deformity surgical options require knowledge of range of procedures and patient suitability. Optimised CT performance, reconstruction and parameter interpretation is essential for surgical planning and communication.
