Reliability of a standardized protocol to calculate cross-sectional chest area and severity indices to evaluate pectus excavatum

Multicenter Study of Pectus Excavatum, Final Report: Complications, Static/Exercise Pulmonary Function, and Anatomic Outcomes

“…Changes at all of these locations were statistically significant (paired t-test ranged from 5.46 to 14.02; all p values <0.001), with effect sizes ranging from moderate at the sternomanubrial joint to large at the xiphoid. 4 Across all patients in this study, these findings demonstrate that the entire chest wall, not just the most depressed area, showed a returned to a more normal contour after surgical correction. The index did not normalize in all patients, perhaps due to posterior curvature of the osseous component of the ribs laterally, diminishing the anterior-posterior diameter, even when the anterior thorax was flat.…”

Radiologic factors related to double-bar insertion in minimal invasive repair of pectus excavatum

“…[6] Since the development of the Haller index, a variety of other indices has been designed; however, the roles of these conventional indices are limited to determining whether or not to perform surgical repair. [7][8][9][10][11][12] In utilizing a minimally invasive procedure for the repair of pectus excavatum, surgeons determine the number of pectus bars required for surgery. Although surgical methods or surgeon's preference may affect the use of double-bar insertion, the morphological characteristics of patients with pectus excavatum are also one of the factors that affect the surgeons' decisions to perform double-bar correction rather than single one.…”

Compressive orthotic bracing in the treatment of pectus carinatum: the use of radiographic markers to predict success

“…Angle of sternal rotation is measured at the point of greatest sternal rotation as described in our earlier report [6]. Asymmetry index is obtained as a ratio of the inner anteroposterior diameter of the right and left thorax [8].…”
