ABSTRACT Nonsynostotic occipital plagiocephaly remains a diagnosis of concern in infancy. This study evaluates factors affecting the onset, treatment, and outcomes of nonsynostotic occipital plagiocephaly.
A retrospective chart review and telephone survey were performed. A posterior occipital deformation severity score was used. Factors such as demographics, behavioral and helmet therapy, feeding patterns, torticollis, multiple gestation pregnancies, prematurity, and congenital nonsynostotic occipital plagiocephaly were evaluated.
One hundred five infants were identified. Of these, 95 percent were Caucasian, 93 percent were from two-parent households, and 70 percent were from households earning more than $50,000. Repositioning was attempted in 95 percent, and 45 percent progressed to helmet therapy. When comparing change in posterior occipital deformation severity score with helmet therapy to repositioning, a difference was found (p < 0.05). Forty-nine percent of patients were breast-fed, and when compared with the general population, a difference was found (p < 0.05). Twenty percent of infants had torticollis, and when compared with population norms, a difference was found (p < 0.05). Twelve percent of patients were twins, and when compared with population norms, more twinning occurred (p < 0.05). Congenital nonsynostotic occipital plagiocephaly was found in 10 percent of patients and did not result in an increased risk of progression to helmet therapy.
This study demonstrates trends that may predict additional risks for developing nonsynostotic occipital plagiocephaly, including torticollis, plural births, and increased socioeconomic affluence. In addition, the nonsynostotic occipital plagiocephaly cohort was breast-fed less than the general population, demonstrating that breast-feeding may be preventative, as breast-fed infants are repositioned more frequently and sleep for shorter periods. As in other studies, cranial molding helmet therapy was more effective in correcting nonsynostotic occipital plagiocephaly than repositioning alone.

    ABSTRACT: For the treatment of pronounced deformational plagiocephaly in infants different therapeutic options are under discussion in the literature. This article presents a prospective observational study of 45 infants enrolled with distinct plagiocephaly and treated with a custom-made helmet orthosis. Treatment with the helmet orthosis was indicated by a difference in the skull diagonals of more than 0.5 cm or a cranial vault asymmetry (CVA) index > 3.5. The follow-up results were controlled with the help of a mobile spatial laser scanner and the CVA index and the skull deformity were measured. The average duration of treatment was 131 days. The CVA index improved from 9.95 to a normal value of 3.35 (median) and the skull deformity improved from 1.3 cm to 0.5 cm (median). The only side effects observed were easily treatable pressure marks. The results of this study reveal that pronounced deformational plagiocephaly can be successfully treated with a custom-made helmet orthosis and closely controlled monitoring.

    ABSTRACT: Object The goal of this study was to review the current literature on orthotic (helmet) therapy use in the treatment of deformational plagiocephaly. Methods PubMed was used to search English articles using the medical subject headings "deformational plagiocephaly" and "orthosis," and "deformational plagiocephaly" and "helmet." Results Forty-two articles were found. There were no Class I studies, 7 Class II studies, 1 Class III study, and 13 Class IV studies. Cranial orthoses have been shown to be effective in treating deformational plagiocephaly. It continues to be debated as to whether the statistical significance of treatment with cranial orthoses compared with conservative therapies is clinically significant. Children older than 12 months of age with deformational plagiocephaly may still benefit from orthotic therapy. The long-term effects of orthotic therapy are controversial. Conclusions There is a lack of Class I literature evidence supporting the use of helmet therapy in deformational plagiocephaly. There are controversies surrounding the use of orthotic therapy such as appropriate use, cost, use in older children, and long-term outcomes. Clinical indications for orthotic therapy need to be better defined with further research studies.

    ABSTRACT: The incidence of deformational plagiocephaly (DP) has increased greatly during the last 2 decades since the recommendation of supine sleeping. Currently, there are 2 treatment options for DP, helmet therapy and repositioning therapy. This research investigated factors that influenced parental decision making about treatment choice and long-term satisfaction with head shape. A retrospective chart review identified 1660 children, now aged 2 to 10 years, seen in the DP clinic meeting inclusion criteria. Questionnaires were mailed to all eligible families. Four-hundred fifty-six completed questionnaires were returned. The questionnaires evaluated demographics of the family, factors that influenced treatment choice, and satisfaction with current head shape. Most of the respondents had white (93%) and male (70%) children. The mothers' mean age at the time of childbirth was 31 years; most of the mothers had a college degree or higher (77%) and household incomes of more than $76,000 (52.6%). Fifteen factors were used to evaluate which ones were significant in influencing parental treatment choice. Severity of the DP and time off work for follow-up appointments were the only 2 factors identified that significantly affected treatment choice. More parents who used helmet therapy reported that they were satisfied with their child's long-term head shape and would choose the same treatment again (P = 0.002) compared with those who used repositioning therapy.
