Neither Carinatum nor Excavatum: Insights Regarding the Novel Postprematurity Thoracic Dysplasia and Traditional Harrison Grooves

jpedsurg.org

In recent years, a new chest wall malformation (CWM), the postprematurity thoracic dysplasia (PPTD), was reported. It was characterized as an inward deviation of the anterior tips of the 6th ribs and a personal history of prematurity and respiratory distress. At the moment, PPTD's prevalence and etiology are yet to be defined. Thus, we aimed to explore and identify patients with a compatible morphology within a large cohort of patients with CWM.

In brief

This article examines postprematurity thoracic dysplasia (PPTD), a newly recognized chest wall malformation distinct from pectus carinatum and excavatum, characterized by inward deviation of the 6th rib tips in patients with premature birth history. The study investigates PPTD prevalence and morphology within a large cohort to better define this emerging condition.

PPTD is a newly described chest wall malformation distinct from pectus carinatum and excavatum.
PPTD presents with inward deviation of the anterior 6th rib tips in patients with prematurity history.
The prevalence and etiology of PPTD remain undefined, requiring further investigation.
PPTD should be considered in differential diagnosis of chest wall deformities in premature infants.
Recognition of PPTD morphology may guide tailored management approaches distinct from traditional pectus repair.
