Plagiocephaly and Brachycephaly: Defending the Benefits of Cranial Helmets

IMG_7203     Google “skull deformity helmets” and nearly half of the   results on the first page are articles that criticize helmet therapy for infants, claiming that the expensive orthotics are a total waste of money. Despite numerous studies that support the effectiveness of helmet therapy in correcting plagiocephaly and brachycephaly [3-6], media sources such as The New York Times and have released articles that discourage treatment [8,9]. The basis for nearly all of helmet therapy criticism arises from a single study published on May 1, 2014, by Renske van Wijk and a team of researchers in the Netherlands [11]. The study, Helmet therapy in infants with positional skull deformation: randomised controlled trial, compared the 24-month outcomes of infants (aged 5 to 6 months) assigned to either a helmet therapy group or a control group that received no treatment. According to the study, helmet therapy was just as effective in correcting skull deformation as no treatment. Thus, van Wijk et al. discourage the use of helmets when treating moderate cases of skull deformation. There are numerous caveats associated with these conclusions, however, that should be taken into account before deciding to leave your infant’s skull deformity untreated.Layla Mewborn

Firstly, here is some background information on the condition in the United States. In 1992, the initiation of the “Back to Sleep” campaign resulted in increased numbers of infants sleeping in a supine position to reduce the risk of Sudden Infant Death Syndrome (SIDS). While the campaign has been extremely effective in reducing instances of SIDS, static supine position is one of the leading risk factors for plagiocephaly. Thus, the increase in skull deformity cases since the 1990s is likely correlated with the 1992 campaign [1]. In 2013, plagiocephaly was estimated to affect 46.6% of infants aged 7 -12 weeks [7]. In addition to prolonged external force resulting from static supine position, other risk factors include torticollis (asymmetric tight neck muscles), prenatal uterine constraint, and perinatal birth injury [1]. The two most common treatments are cranial helmets and repositioning practices—a more conservative approach where infants are positioned in prone for short periods of time. According to the van Wijk study, however, natural course is just as effective as the more aggressive, cranial helmet treatment.   Bling Your Band

Following publication on May 1, 2014, there was a high volume of critical responses from members of the medical community regarding the study’s results and conclusions. One of the most common criticisms is that the study did not include infants with severe deformities, torticollis, or other developmental neuromuscular issues. Thus, it is still widely believed that infants with severe skull deformities or neuromuscular problems stand to benefit from cranial helmets. Jordan Steinberg, a pediatric plastic surgeon, points out the high percentages of study participants that experienced problems with the cranial helmet during its use in the study [10]. Reportedly, 96% of the infants experienced skin irritation, 76% unpleasant odor, and 33% felt some sort of pain from the helmet. Furthermore, 73% of participants reported improper fit and shifting of the orthotic [11]. Noting these issues, and the low percentages of full recovery in both subject groups, Steinberg concludes that the participants received “inadequate treatment” [10]. Kevin Kelly, a research consultant at Cranial Technologies also comments on these statistics stating, “The lack of improvement seen in their study was the direct result of their ill-fitting helmets” [2]. Had participants received properly fitting helmets and proper care, van Wijk et al. may have observed significantly different outcomes.helmet

Although many view skull deformity as solely a cosmetic issue, “untreated cranial asymmetries have been linked to visual defects, ear infections, middle ear malfunction, jaw bone changes, developmental delay, learning difficulties, and other psychomotor delays” [12]. Treating instances of plagiocephaly and brachycephaly in a timely manner is important for ensuring proper development. The results of van Wijk’s study are not completely reliable and do not annul the value of cranial helmets. The study did not include severe cases of skull deformity, and patients were not properly fitted with their orthotics. More research is certainly necessary to properly characterize the effectiveness of cranial helmets. For the time being, seeing as skull deformities can lead to numerous developmental complications, it should be of primary concern to treat the condition rather than quickly dismissing a device that has been historically successful in correcting countless cases of skull deformity.
