Abstract:
Objective To investigate the application of 3-D scanning in the diagnosis and evaluation of pectus excava-tum.Methods From July 2016 to June 2017, chest CT concomitant 3-D scanning were performed in 90 pectus excavatum pa-tients before Nuss procudure.Another 30 cases underwent chest CT scanning for non-chest deformity causes were chosen as a control group.The transverse and anterior-posterior maximum diameter through the deepest point of chest wall deformity were measured.The surface topography index and Haller index were calculated respectively .Results There was a positive correla-tion between CT and 3-D scanning diameters of the transverse and anterior-posterior maximum diameters, and consistency rates were 94% and 82%, respectively.There was significant difference between pectus excavatum group 1.82 ±0.21 and control group 1.41 ±0.07 in the STI(P<0.001).There was a positive correlation between Haller index 5.12 ±3.36 and STI 1.82 ± 0.21, and consistency rate was 89%.The Delong's test showed no significant difference between ROC of HI and STI(Z =1.18, P=0.28).Conclusion 3-D scanning and STI of pectus excavatum is a validated alternative for CT and Haller index, especially in the infant and non-surgical treatment PE cases.
