Outcomes for patients with plagiocephaly are typically reported by recording the initial level of oblique asymmetry present and the amount of correction afforded by a cranial remolding orthosis (CRO). Cranial vault asymmetry (CVA) is used by many insurance companies as a criterion for medical necessity, so it is convenient to reference clinically for insurance approval and use as an outcome measure. These point- to-point measurements are limited: They don’t represent the entire 3D aspect of an abnormally shaped head and often do not reflect the primary concern of the parents/caregivers. A CRO may improve the CVA below 5mm, but substantial asymmetry that is not accounted for by the CVA measurements may still be present.
