Effectiveness of Cranial Remolding Orthosis in Treatment of Nonsynostotic Plagiocephaly.

Introduction: The prevalence of cranial deformities, including nonsynostotic plagiocephaly, has been increasing, especially since the “Back to Sleep” campaign. Treatment of these deformities can use a cranial remolding orthosis or helmet. However, inconsistencies in results of studies of cranial remolding orthoses have made it increasingly more difficult for providers to accurately make recommendations for individuals with nonsynostotic plagiocephaly. Therefore, the purpose of this study was to assess the effectiveness of cranial remolding orthoses effective in treating nonsynostotic plagiocephaly by reducing cranial vault asymmetry (CVA) and to assess whether age and severity impact length and success of treatment. Materials and Methods: A retrospective analysis of patient files from September 2019–September 2020 was conducted. Paired samples of initial average and discharge average CVA measures and severity ratings were compared. Regression analyses were used to assess the relationship between all factors and severity rating at discharge. Results: A total of 106 infants (73 male, 33 female) were included in final analyses. Results indicated a significant difference between initial and discharge CVA and severity rating as a result of cranial remolding orthosis treatment. It was found that CVA at initial evaluation significantly predicted CVA at discharge (β = 0.73, P = 0.000) and severity at discharge (β = 0.52, P = 0.000), but all other variables were not significant predictors. Conclusions: The cranial remolding orthosis is an effective treatment in the correction of nonsynostotic plagiocephaly when used by a certified practitioner. In addition, this study found that treatment led to significant improvement regardless of age or initial severity. [ABSTRACT FROM AUTHOR]
