Effects of Initial Age and Severity on Cranial Remolding Orthotic Treatment for Infants with Deformational Plagiocephaly

Abstract

The aim of this study is to review the effects of an infant’s presenting age and severity of deformation on cranial remolding orthotic (CRO) treatment outcomes for patients with deformational plagiocephaly. This study is a retrospective chart review of 499 infants with non-synostotic plagiocephaly who completed CRO treatment. Data collected included age at start of treatment, head shape measurements before and after treatment, total months of CRO treatment, and other factors such as presence/absence of prematurity. The infants were divided into subgroups according to age and severity at initiation of treatment and data for subgroups was analyzed to track the change in head shape over the course of treatment, review overall treatment duration, and discuss the rate of change of cranial deformation. Overall, treatment times tended to statistically increase with increasing initial severity and age. Posttreatment asymmetry measurements statistically trended to greater residual deformation in infants who began treatment in the older or more severe subcategories. This indicates that younger and less severe infants have shorter treatment durations and less residual cranial deformation after CRO treatment. Therefore, clinical consideration may need to be taken to treat infants at younger ages or prior to progression of the cranial deformity.
