Orthotic Helmet Therapy for Deformational Plagiocephaly: Stratifying Outcomes by Insurance

OBJECTIVE

Deformational Plagiocephaly (DP) is commonly treated with cranial orthosis, or helmet therapy. A large, national study on the impact of insurance status on helmet outcomes is lacking. We assessed treatment outcomes for helmet therapy based on insurance status.

DESIGN

This was a retrospective data analysis of patients referred to Cranial Technologies, Inc for helmet therapy between 2014-2020 across 21 states.

PATIENTS, PARTICIPANTS

There were a total of 211,417 patients referred for helmeting, of whom 141,513 received helmet therapy.

MAIN OUTCOMES MEASURES

Multivariate regression was used to assess the relationship of insurance status with post-treatment residual flattening, measured by cephalic index (CI) and cranial vault asymmetry index (CVAI), and treating provider rating of success.

RESULTS

Patients with Medicaid were more likely to complete treatment with residual flattening measured by CI and CVAI when compared to patients with private insurance (OR: 1.58, CI: 1.51-1.65, p < 0.001 and OR: 1.21, CI: 1.15-1.28, p < 0.001, respectively). Providers of patients with Medicaid were more likely to give a low rating of success following treatment (OR: 3.25, CI: 2.70-3.92, p < 0.001).

CONCLUSIONS

Our study investigating the impact of insurance status on helmet therapy across 21 states found that patients with Medicaid were more likely to experience residual flattening and have lower provider-rated outcomes compared to those with commercial insurance. Given significant caregiver burden posed by helmet therapy, which requires frequent visits and consistent helmet use, caregivers of patients with Medicaid may require greater support to reduce outcome disparities observed here.

Neurocognitive Outcomes in Deformational Plagiocephaly: Is There an Association between Morphologic Severity and Results?

BACKGROUND

The neurodevelopmental effects of skull asymmetry and orthotic helmet therapy for deformational plagiocephaly (DP) have had limited investigation. This study assessed the long-term neurocognitive outcomes in patients with DP and their association with orthotic helmet therapy and head shape abnormality.

METHODS

A total of 138 school-age children with a history of DP, 108 of whom received helmet therapy, were tested with a neurocognitive battery assessing academic achievement, intelligence quotient, and visual-motor function. Severity of presenting plagiocephaly was calculated using anthropometric and photometric measurements. Analysis of covariance was used to compare outcomes between helmeted and nonhelmeted cohorts, unilateral plagiocephaly and concomitant brachycephaly, and left-sided and right-sided plagiocephaly. The association between severity of plagiocephaly and neurocognitive outcome was assessed through a residualized change approach.

RESULTS

There were no significant differences in neurocognitive outcomes between the helmeted and nonhelmeted DP cohorts or the unilateral plagiocephaly and brachycephaly cohorts. Participants with left-sided DP had significantly lower motor coordination scores than participants with right-sided DP (84.8 versus 92.7; effect size = -0.50; P = 0.03). There was a significant laterality by cephalic index interaction, with a negative association between cephalic index and reading comprehension and spelling for participants with left-sided DP. No significant associations were found between severity of presenting or posttreatment deformity and neurocognitive outcome.

CONCLUSIONS

Pretreatment and posttreatment severity of plagiocephaly were not correlated with neurocognitive function at school age. Helmet therapy was not associated with better or worse long-term neurocognitive function. However, participants with left-sided DP demonstrated worse neurocognitive outcomes than participants with right-sided DP in the domains of motor coordination and some types of academic achievement.

[Does positional plagiocephaly affect the need for orthodontic treatment, and the mandibular and occlusal symmetry?]

INTRODUCTION

Positional plagiocephaly (PP) is characterized by an asymmetrical flatness of the posterior part of the skull which may involve the frontal part of the skull and the face. The aim is to assess whether children and adolescents with PP have more occlusal and skeletal asymmetries and whether the need for orthodontic treatment is greater than in the healthy population.

MATERIAL AND METHOD

A comparative cross-sectional epidemiological study was carried out. One hundred children and adolescents were included: 50 in the PP group and 50 in the control group. The need for orthodontic treatment was assessed by the Index of Orthodontic Treatment Need (IOTN). The mandibular and dental asymmetries were measured on lateral cephalometry by two indexes: index of mandibular asymmetry (IMA) and index of dental asymmetry (IDA) respectively. Chi and Student independence tests were performed with a threshold of 5%.

RESULTS

The tests are significant for IMA (p = 0.02) and IOTN (p = 0.000012). IDA is insignificant.

DISCUSSION

Orthosurgical treatment of mandibular laterognathies by mandibular recentering sometimes creates mandibular asymmetry, while the shift is basal. We must be able to act early on the vault of the skull to hope to obtain a consecutive effect on the base and therefore on the position of the glenoid cavities. Management by manual therapy and early cranial orthosis could be estimated.

CONCLUSION

The need for orthodontic treatment is significantly greater in PP. Unlike mandibular asymmetry, dental asymmetry is not significantly greater than in the control group, testifying to the adaptive capacities of the organism.

Deformational Plagiocephaly and Reduced Cervical Range of Motion: A Pediatric Case Series in a Chiropractic Clinic

CONTEXT

Deformational plagiocephaly, a non-synostotic asymmetry of the occipital bone, is a frequent occurrence in infants, with a peak incidence of 19.7% at 4 months of age. One aetiology is hypothesized to be due to restriction in normal cervical spine motion.

OBJECTIVE

This study aimed to determine if an association exists between plagiocephaly and restrictions in the passive range of motion (PROM) of the cervical spine.

METHODS

A retrospective analysis of the clinical records of 150 consecutive cases was performed, with specific inclusion/exclusion criteria applied. Data were collated and analysed.

SETTING

Private chiropractic practice, Victoria, Australia.

PARTICIPANTS

Participants were 150 infants under 12 months of age, with a mean age of 122 ± 60.6 days and a range in age of 42 to 245 days.

OUTCOME MEASURES

The outcome included measurement of the cervical PROM, identification of the location of the restriction, and a decision about the presence of plagiocephaly.

RESULTS

In the 150 cases, 78.7% were found to have restrictions in cervical PROM, with 60.2% showing an indication of plagiocephaly. In the cases with plagiocephaly, 92.2% were found to have restrictions in cervical PROM.

CONCLUSION

The presence of plagiocephaly was associated with a higher prevalence of restriction in cervical PROM. A statistically significant association existed between restriction of the occipitoatlantal joint and development of contralateral deformational plagiocephaly. Future clinical trials assessing the effectiveness of spinal manipulative therapy in the treatment and management of restricted cervical PROM and plagiocephaly in infants are needed.

Efficacy of pediatric integrative manual therapy in positional plagiocephaly: a randomized controlled trial

BACKGROUND

Positional plagiocephaly frequently affects healthy babies. It is hypothesized that manual therapy tailored to pediatrics is more effective in improving plagiocephalic cranial asymmetry than just repositioning and sensory and motor stimulation.

METHODS

Thirty-four neurologically healthy subjects aged less than 28 weeks old with a difference of at least 5 mm between cranial diagonal diameters were randomly distributed into 2 groups. For 10 weeks, the pediatric integrative manual therapy (PIMT) group received manual therapy plus a caregiver education program, while the controls received the same education program exclusively. Cranial shape was evaluated using anthropometry; cranial index (CI) and cranial vault asymmetry index (CVAI) were calculated. Parental perception of change was assessed using a visual analogue scale (- 10 cm to + 10 cm).

RESULTS

CVAI presented a greater decrease in PIMT group: 3.72 ± 1.40% compared with 0.34 ± 1.72% in the control group (p = 0.000). CI did not present significant differences between groups. Manual therapy led to a more positive parental perception of cranial changes (manual therapy: 6.66 ± 2.07 cm; control: 4.25 ± 2.31 cm; p = 0.004).

CONCLUSION

Manual therapy plus a caregiver education program improved CVAI and led to parental satisfaction more effectively than solely a caregiver education program.

Safe Sleep, Plagiocephaly, and Brachycephaly: Assessment, Risks, Treatment, and When to Refer

The Safe to Sleep campaign started in 1994, reducing the risk of sudden infant death syndrome (SIDS) by 40% to 60%. However, an undesirable consequence has been a 400% to 600% increase in positional head deformities. We review the risks for positional plagiocephaly or brachycephaly, treatment modalities, and when to refer. Differential diagnoses for non-positional deformities are discussed. Risks for positional head deformities include prenatal, perinatal and postnatal factors. These include torticollis, inadequate tummy time, abnormal intrauterine positioning, premature or postmature birth, prolonged labor, complex medical conditions, prolonged hospitalizations, developmental delay, and use of supportive or convenience devices. Recommended treatment involves repositioning techniques or physical therapy with or without helmet use. Early referral to physical therapy or a head shape program insures better outcomes for full correction of the deformity. The severity of residual deformities is directly related to the age at which the child is referred. [Pediatr Ann. 2020;49(10):e440-e447.].

Applicative Factors of Helmet Molding Therapy in Late-diagnosed Positional Plagiocephaly

BACKGROUND

Although the benefits of helmet therapy for positional plagiocephaly are strongly correlated with age, the effective period remains controversial. However, most physicians agree that effective results can be obtained in patients within the age of 6 months. Owing to the characteristics of positional plagiocephaly in Koreans, many Korean patients have delayed diagnosis, and because this results in delayed onset of the helmet therapy, the outcomes remain largely underevaluated. In the management of late-diagnosed positional plagiocephaly, we aimed to determine the factors affecting the effective application of helmet therapy.

METHODS

We recruited 39 consecutive patients with positional plagiocephaly who received helmet therapy and completed the treatment between December 2008 and June 2016. The ages at initiation and completion of treatment, duration of daily use, initial and final absolute diagonal differences, cephalic index, and cranial vault asymmetry index (CVAI) were analysed using data retrospectively collected from the patients' medical records.

RESULTS

We identified 12 patients with late-diagnosed positional plagiocephaly, of whom 83.33% were effectively treated. The effective change in CVAI (%) was affected by age at treatment initiation (P = 0.001), initial absolute diagonal distance differences (P < 0.001), and initial CVAI (P < 0.001). Up to 9 months, a gradual change of at least 1% CVAI was attained. Treatment initiation at ages < 5.5 months was beneficial. Even at a later age, patients with an initial absolute diagonal distance difference of > 13.50 mm and initial CVAI of > 11.03% could receive effective helmet therapy.

CONCLUSION

The efficacy of helmet therapy in late-diagnosed patients can be predicted on the basis of not only age at treatment initiation, but also initial absolute diagonal distance differences and initial CVAI. We anticipate that even patients with late-diagnosed positional plagiocephaly can expect better helmet therapy outcomes.

Infant Cranial Deformity: Cranial Helmet Therapy or Physiotherapy?

Objective: To compare cranial helmet therapy (CHT) and physiotherapy (PT) for the effective treatment of positional plagiocephaly in infants in terms of improving functional recovery. Methods: This was a prospective cohort study involving 48 infants between 5–10 months of age with cranial deformities. The Cranial Vault Asymmetry Index (CVAI) and the Brunet–Lezine scale were calculated at the initiation of the study and after 40 treatment sessions. Results: The infants’ first assessment showed a delay in overall development areas with a global developmental quotient (DQ) (posture, coordination, sociability, and language) of 80.15. Although developmental improvements were observed in both groups in the Brunet–Lezine scale after treatment, the MANCOVA test showed no significant differences (F(5) = 0.82, p = 0.506, eta² = 0.09). The CVAI reduced to 4.07% during the final evaluation in the cranial helmet group and 5.85% in the physiotherapy group without any significant differences between the two therapies (p = 0.70). Conclusions: No statistically significant differences were found between CHT and PT. After treatment, improvements from baseline measurements were observed in each of the readings of cranial deformity.

Parental Satisfaction with the CranioCap: A New Cranial Orthosis for Deformational Plagiocephaly

Objective

This study evaluates the safety and parent satisfaction of a new cranial orthosis designed to treat deformational plagiocephaly.

Design

A retrospective phone survey of parental satisfaction of a new cranial orthosis that has Food and Drug Administration (FDA) clearance for treatment of deformational plagiocephaly.

Setting

A tertiary referral center for children with craniofacial anomalies.

Patients

The first 232 consecutive infants enrolled in this program were retrospectively reviewed.

Interventions

Infants were entered in the cranial orthosis program if they had been diagnosed with deformational plagiocephaly and were less than 1 year of age, and if the infant's parents were interested in enrolling in a monitored cranial orthosis program.

Main Outcome Measure

After completing therapy, a random sample of 81 parents (half completing treatment) was surveyed. Parents rated the improvement in their infant's head shape from 1 (least) to 5 (most). They were asked if they would repeat the program with a subsequent child. To date, 70% (162/ 232) have completed treatment.

Results

The orthosis was worn an average of 89 days. On average, parents rated head shape improvement 4.06 out of 5 (range, 3 to 5). Of parents surveyed, 81 (100%) would repeat the program with a subsequent child. There were three (3/232 or 1.3%) minor complications: one child with a persistent rash that resolved with termination of orthosis use, one child with a skin irritation that resolved with orthosis recontouring, and one child who could not be successfully fit.

Conclusions

The CranioCap, a new cranial orthosis with clearance for treatment of deformational plagiocephaly, appears to be safe, well tolerated, and has excellent parent satisfaction.

[Efficacy of sleep position correction for treating infants with positional plagiocephaly]

OBJECTIVE

To investigate the efficacy of 2-month course of sleeping position correction in the treatment of positional plagiocephaly in infants aged <8 months.

METHODS

A total of 73 infants with positional plagiocephaly between January 2015 and June 2016 were divided into treatment group (n=46) and control group (n=27) according to parents' wishes. The treatment group received sleeping position correction, while the control group received sleep curve mattress. The oblique diameters A and B in the two groups were measured and the cranial vault asymmetry (CVA) was calculated before and after treatment. The severity of positional plagiocephaly based on CVA was compared between the two groups before and after treatment. The Gesell Developmental Scale was used to determine the developmental quotients (DQs) in the motor, adaptive, language, and social domains in the two groups before and after treatment.

RESULTS

Before treatment, there were no significant differences in oblique diameters A and B, CVA, and DQs in the four specific domains between the two groups (P>0.05). After 2 months of treatment, the treatment group had a significantly greater oblique diameter B and a significantly smaller CVA than the control group (P<0.05); there were no significant differences in DQs in the four specific domains between the two groups (P>0.05). After treatment, both groups had significant improvements in oblique diameters A and B, CVA, and DQs in the motor and adaptive domains (P<0.01); moreover, the treatment group showed a significant improvement in the DQs in the social domain (P<0.01). There was no significant difference in the severity of positional plagiocephaly between the two groups before and after treatment (P>0.05).

CONCLUSIONS

For infants with positional plagiocephaly, sleeping position correction has better efficacy and is more convenient and economical than the sleep curve mattress, so it holds promise for clinical application.

The course of skull deformation from birth to 5 years of age: a prospective cohort study

In a continuation of a prospective longitudinal cohort study in a healthy population on the course of skull shape from birth to 24 months, at 5 years of age, 248 children participated in a follow-up assessment using plagiocephalometry (ODDI-oblique diameter difference index, CPI-cranio proportional index). Data from the original study sampled at birth, 7 weeks, 6, 12, and 24 months were used in two linear mixed models.

MAIN FINDINGS

(1) if deformational plagiocephaly (ODDI <104%) and/or positional preference at 7 weeks of age are absent, normal skull shape can be predicted at 5 years of age; (2) if positional preference occurs, ODDI is the highest at 7 weeks and decreases to a stable lowest value at 2 and 5 years of age; and (3) regarding brachycephaly, all children showed the highest CPI at 6 months of age with a gradual decrease over time.

CONCLUSION

The course of skull deformation is favourable in most of the children in The Netherlands; at 5 years of age, brachycephaly is within the normal range for all children, whereas the severity of plagiocephaly is within the normal range in 80%, within the mild range in 19%, and within the moderate/severe range in 1%. Medical consumption may be reduced by providing early tailored counselling. What is Known: • Skull deformation prevalence increased after recommendations against Sudden Infant Death Syndrome, little is known about the longitudinal course. • Paediatric physical therapy intervention between 2 and 6 months of age reduces deformational plagiocephaly at 6 and 12 months of age. What is New: • The course of skull deformation is favourable in most of the children in The Netherlands; at 5 years of age, deformational brachycephaly is within the normal range for all children, whereas the severity of deformational plagiocephaly is within the normal range in 80%, within the mild range in 19%, and within the moderate to severe range in only 1%. • Paediatric physical therapy intervention does not influence the long-term outcome; it only influences the earlier decrease of the severity of deformational plagiocephaly.

Guidelines: Congress of Neurological Surgeons Systematic Review and Evidence-Based Guideline for the Management of Patients With Positional Plagiocephaly: The Role of Physical Therapy

BACKGROUND

Evidence-based guidelines are not currently available for the treatment of positional plagiocephaly and, in particular, for the use of physical therapy for treatment.

OBJECTIVE

To answer the question: "does physical therapy provide effective treatment for positional plagiocephaly?" Treatment recommendations are created based on the available evidence.

METHODS

The PubMed and the Cochrane Library were queried using MeSH headings and key words relevant to the objective of this systematic review. Abstracts were reviewed, after which studies meeting the inclusion criteria were selected and graded according to their quality of evidence (Classes I-III). Evidentiary tables were constructed that summarized pertinent study results, and recommendations were made based on the quality of the literature (Levels I-III).

RESULTS

Three studies met criteria for inclusion. Two randomized, controlled trials (Class I and Class II) and 1 prospective study assessing plagiocephaly as a secondary outcome measure (Class III) were included.

CONCLUSION

Within the limits of this systematic review, physical therapy is significantly more effective than repositioning education as a treatment for positional plagiocephaly. There is no significant difference between physical therapy and a positioning pillow as a treatment for positional plagiocephaly. However, given the American Academy of Pediatrics' recommendation against soft pillows in cribs to ensure a safe sleeping environment for infants, physical therapy must be recommended over the use of a positioning pillow.

Congress of Neurological Surgeons Systematic Review and Evidence-Based Guideline on the Role of Cranial Molding Orthosis (Helmet) Therapy for Patients With Positional Plagiocephaly

BACKGROUND

No evidence-based guidelines exist on the role of cranial-molding orthosis (helmet) therapy for patients with positional plagiocephaly.

OBJECTIVE

To address the clinical question: "Does helmet therapy provide effective treatment for positional plagiocephaly?" and to make treatment recommendations based on the available evidence.

METHODS

The US National Library of Medicine Medline database and the Cochrane Library were queried by using MeSH headings and key words relevant to the objective of this systematic review. Abstracts were reviewed, after which studies meeting the inclusion criteria were selected and graded according to their quality of evidence (Classes I-III). Evidentiary tables were constructed that summarized pertinent study results, and, based on the quality of the literature, recommendations were made (Levels I-III).

RESULTS

Fifteen articles met criteria for inclusion into the evidence tables. There was 1 prospective randomized controlled trial (Class II), 5 prospective comparative studies (Class II), and 9 retrospective comparative studies (Class II).

CONCLUSION

There is a fairly substantive body of nonrandomized evidence that demonstrates more significant and faster improvement of cranial shape in infants with positional plagiocephaly treated with a helmet in comparison with conservative therapy, especially if the deformity is severe, provided that helmet therapy is applied during the appropriate period of infancy. Specific criteria regarding the measurement and quantification of deformity and the most appropriate time window in infancy for treatment of positional plagiocephaly with a helmet remains elusive. In general, infants with a more severe presenting deformity and infants who are helmeted early in infancy tend to have more significant correction (and even normalization) of head shape.

Guidelines: Congress of Neurological Surgeons Systematic Review and Evidence-Based Guideline on the Management of Patients With Positional Plagiocephaly: The Role of Repositioning

BACKGROUND

Plagiocephaly, involving positional deformity of the calvarium in infants, is one of the most common reasons for pediatric neurosurgical consultation.

OBJECTIVE

To answer the question: "what is the evidence for the effectiveness of repositioning for positional plagiocephaly?" Treatment recommendations are provided based on the available evidence.

METHODS

The National Library of Medicine MEDLINE database and the Cochrane Library were queried using MeSH headings and key words relevant to repositioning as a means to treat plagiocephaly and brachycephaly. Abstracts were reviewed to identify which studies met the inclusion criteria. An evidentiary table was assembled summarizing the studies and the quality of evidence (Classes I-III). Based on the quality of the literature, a recommendation was rendered (Level I, II, or III).

RESULTS

There were 3 randomized trials (Class I), 1 prospective cohort study (Class II), and 6 retrospective cohort studies (Class III). Repositioning education was found to be equal to a repositioning device and inferior to a physical therapy program. Five of the 7 cohort studies comparing repositioning with a helmet reported helmets to be better and take less time.

CONCLUSION

Within the limits of this systematic review, repositioning education is effective in affording some degree of correction in virtually all infants with positional plagiocephaly or brachycephaly. Most studies suggest that a molding helmet corrects asymmetry more rapidly and to a greater degree than repositioning education. In a Class I study, repositioning education was as effective as repositioning education in conjunction with a repositioning wrap/device. Another Class I study demonstrated that a bedding pillow was superior to physical therapy for some infants. However, in keeping with the American Academy of Pediatrics' warning against the use of soft positioning pillows in the sleeping environment, the Task Force recommends physical therapy over any positioning device.

Therapy effects of head orthoses in positional plagiocephaly

PURPOSE

Head orthoses offer a valuable therapeutic option for infants with positional plagiocephaly. The aim of this retrospective study was to evaluate the influence of therapy start and duration due to improvement of cranial asymmetry.

MATERIAL AND METHODS

A total of 102 children during the years 2009-2014 were included. The patient cohort was divided according to age at the beginning of therapy (younger/older than 7.5 months) and duration (less/more than 150 days). To evaluate the therapy, ear shift (ES), Cranial Vault Asymmetry Index (CVAI), and Cranial Index (CI) were calculated pre- and post-therapy by using three-dimensional photogrammetry measurements.

RESULTS

Treatment with head orthoses led to a significant reduction of CVAI in groups with less and more than 150 days of therapy (p < 0.0001). A significant reduction in CVAI was observed (p = 0.0235) in children younger than 7.5 months in short-term therapy. At the end of therapy, no significant difference was found in the groups, whether treated with short- or long-term head orthoses (p = 0.0813), although CVAI was significantly different comparing the third time point of both groups for treatment duration (p = 0.017). The major positive effect of helmet therapy has been seen after 75 days of treatment. A treatment that was longer than 150 days did not show any significant improvement concerning the cranial asymmetry.

CONCLUSIONS

Helmet therapy is a reliable method in the treatment of positional plagiocephaly to improve cephalic asymmetries. This retrospective study indicates that an early beginning can lead to satisfying results after short-term therapy.

Sonographic Analysis of Changes in Skull Shape After Cranial Molding Helmet Therapy in Infants With Deformational Plagiocephaly

OBJECTIVES

-The purpose of this study was to investigate the changes in skull shape on sonography after cranial molding helmet therapy in infants with deformational plagiocephaly.

METHODS

-Twenty-six infants who were treated with cranial molding helmet therapy were recruited. Caliper and sonographic measurements were performed. The lateral length of the affected and unaffected sides of the skull and cranial vault asymmetry index were measured with calipers. The occipital angle, defined as the angle between lines projected along the lambdoid sutures of the skull, was calculated by sonography. The occipital angle difference and occipital angle ratio were also measured. All caliper and sonographic measurements were performed in each infant twice before and twice after treatment.

RESULTS

-The study group included 12 male and 14 female infants with a mean age ± SD of 6.2 ± 3.5 months. The mean treatment duration was 6.0 ± 2.5 months. The difference in lateral length before and after helmet therapy was significantly greater on the affected skull than the unaffected skull (16.7 ± 12.7 versus 9.0 ± 13.4 mm; P < .01). The difference in the occipital angle before and after helmet therapy was significantly greater on the affected skull than the unaffected skull (-5.7° ± 7.3° versus 4.2° ± 7.9°; P < .01). The cranial vault asymmetry index and occipital angle ratio were significantly reduced after helmet therapy (cranial vault asymmetry index, 9.3% ± 2.3% versus 3.5% ± 3.0%; occipital angle ratio, 1.07 ± 0.05 versus 1.01 ± 0.01; P < .05).

CONCLUSIONS

-These results suggest that occipital angle measurements using sonography, combined with cephalometry, could provide a better understanding of the therapeutic effects of cranial molding helmet therapy in infants with deformational plagiocephaly.

[Positional plagiocephaly in infancy: diagnosis and management]

Positional plagiocephaly in the newborn corresponds to a posterior flattening and asymetry of the head. Its incidence has significantly increased since the "back to sleep" campain in the nineteen nineties to prevent sudden infant death syndrome. The posterior deformation usually worsens during the first six months of life when the skull is susceptible to posterior constant pressure which induces the deformation. Spontaneous outcome can be favorable. Treatment is always conservative and consists in positionnal exercise, physiotherapy and osteopathy. In some cases treatment with a helmet is recommended for a period of three months usually. Posterior positionnal plagiocephaly has no consequences on the brain's developement an is considered as an esthetic issue. In most cases good results are obtained after management with a custom fitted helmet when needed.

Clinical profile and evolution of infants with deformational plagiocephaly included in a conservative treatment program

PURPOSE

The aim of this study was to evaluate the results of a conservative intervention in infants with plagiocephaly according to their specific clinical profile.

METHODS

Prospective clinical trial in which 104 infants with plagiocephaly accompanied or not by congenital or positional torticollis were referred to Early Care and Monitoring Unit (USAT) of San Cecilio Hospital in Granada, between 2009 and 2012. All the infants, grouped into three categories of severity, were included in the physiotherapy protocol until adequate craniofacial morphology and motor development were achieved. The study included an assessment of parents and infants. Parents were assessed with a questionnaire about the mother's medical history and birth-related issues. The assessment of infants included anthropometric measures, a positional assessment, the observation of the head, the assessment of severity, and motor development.

RESULTS

Birth characteristics were similar in the total sample but showed different clinical profiles according to treatment aspects. More specifically, infants with severe plagiocephaly were referred to treatment later and spent more time in treatment; use of an orthotic helmet was also more prevalent in this category. There were also significant differences (P < 0.05) in the acquisition of specific gross motor skills depending on the severity of plagiocephaly.

CONCLUSION

The findings suggest that the physiotherapy protocol presented is effective to correct plagiocephaly. Severity of plagiocephaly is a marker that should be taken into account when designing actions aimed at improving gross motor skill development.

A randomized controlled trial of positioning treatments in infants with positional head shape deformities

BACKGROUND

Randomized controlled trials of treatment for deformational plagiocephaly and brachycephaly have been lacking in the literature.

METHODS

Infants (n = 126) presenting to a plagiocephaly clinic were randomized to either positioning strategies or to positioning plus the use of a Safe T Sleep™ positioning wrap. Head shape was measured using a digital photographic technique, and neck function was assessed. They were followed up at home 3, 6 and 12 months later.

RESULTS

There was no difference in head shape outcomes for the two treatment groups after 12 months of follow-up, with 42% of infants having head shapes in the normal range by that time. Eighty per cent of children showed good improvement. Those that had poor improvement were more likely to have both plagiocephaly and brachycephaly and to have presented later to clinic.

CONCLUSIONS

Most infants improved over the 12-month study period, although the use of a sleep positioning wrap did not increase the rate of improvement.

[Cranial osteopathy as a complementary treatment of postural plagiocephaly]

For the majority of neonates and young infants, appropriate postures and standard physiotherapy succeed in preventing or correcting acquired cranial deformations (fetal due to restricted mobility in utero or postnatal secondary to exclusive dorsal decubitus). However in some cases, when postural management is not efficient, pediatricians will be asked by the parents about the potential benefits of osteopathy. What is osteopathic treatment? At first, diagnostic palpation will identify which suture is normally mobile with the respiratory cycle, and which has limited or absent mobility secondary to abnormal postures. Later on, the goal of the therapeutic phase is to mobilise impaired sutures, by various gentle maneuvers depending on the topography of the impairment. The treatment is not restricted to the skull but extended to the spine, pelvis and lower extremities which contribute to the deformative sequence. Osteopathic treatment belongs to complementary medicine, therefore demonstration of its scientific value and favorable results have to be provided. Based on randomized studies, the answer is yes, it significantly decreases the degree of asymmetry. Do postural deformations matter to the development of an healthy infant? It seems that the prejudice is not only esthetic but also functional, however more research is necessary. In conclusion, pediatricians should be more aware of the method and expectations: major deformative sequence since birth and increasing deformations despite preventive postures and standard physiotherapy are reasonable indications for such complementary treatment. "Preventive" osteopathy in maternity is not justified. Moreover osteopathy has no place in the treatment of craniosynostosis ; the latter belong to malformations, completely distinct from postural deformations.

[Babies with cranial deformity]

Plagiocephaly was diagnosed in a baby aged 4 months and brachycephaly in a baby aged 5 months. Positional or deformational plagio- or brachycephaly is characterized by changes in shape and symmetry of the cranial vault. Treatment options are conservative and may include physiotherapy and helmet therapy. During the last two decades the incidence of positional plagiocephaly has increased in the Netherlands. This increase is due to the recommendation that babies be laid on their backs in order to reduce the risk of sudden infant death syndrome. We suggest the following: in cases of positional preference of the infant, referral to a physiotherapist is indicated. In cases of unacceptable deformity of the cranium at the age 5 months, moulding helmet therapy is a possible treatment option.

A case presentation of early intervention with dolichocephaly in the NICU: collaboration between the primary nursing team and the developmental care specialist

Dolichocephaly, narrow width and long anterior-posterior cranial distance, is more commonly seen in preterm than in term infants. It seems to persist after NJCU discharge and may be a marker for adverse neurodevelopment. This article reports a case of cranial molding in one extremely low birth weight infant. He was placed on a viscoelastic mattress and a twice weekly developmental care program. Cranial molding was measured using the cranial index (CI), a ratio of width to length. Initially, the patient presented with dolichocephaly (CI=72 percent). y week 2, CI measurements approached normal limits (CI=75 percent). When placed on continuous positive airway pressure, the infant presented with substantial dolichocephaly (CI=66.7 percent). Following position changes to midline, CI measurements continued to improve and remained within normal limits until discharge. This dual-element program was feasible, acceptable to parents and staff and may be effective for identifying and managing dolichocephaly.

Long-term outcome of infants with positional occipital plagiocephaly

BACKGROUND

Despite much interest in positional (deformational) plagiocephaly, the natural history is unclear. The purpose of this study was to determine cosmetic and developmental outcomes at a minimum of 5 years of age in children diagnosed in infancy with positional plagiocephaly (PP) and the impact of cranial orthotic use.

METHODS

A questionnaire survey was sent to parents of children diagnosed with PP in infancy and now aged more than 5 years. A retrospective review of the child's clinic chart was performed of consenting families, and prospective follow-up was done when families agreed to return for assessment.

RESULTS

Of 278 eligible children with plagiocephaly, questionnaires were completed by 65 parents, and 27 brought their child for assessment. Participants and nonparticipants were similar. Cranial orthoses were used in 18 of 65 children. Parents perceived the cosmetic appearance of their child as "very abnormal" in 2, "mildly abnormal" in 25, and "normal" in 38. Residual asymmetry was noted by parents in 58%, but only 21% were concerned about appearance. In the last year, 7.7% of children commented about asymmetry of head, and 4.6% were teased occasionally. Thirty-three percent had received learning assistance, and 14% were in a special class. Long-term outcomes, as perceived by the parent or child, were no different between children with and without orthosis use.

CONCLUSIONS

The results allow better counselling of parents about outcome of infants with PP, reducing anxiety, and allowing more rational selection of management modality.

Enigmas y confusiones en el diagnóstico y tratamiento de la plagiocefalia posicional. Protocolo asistencial

INTRODUCTION

Positional plagiocephaly is currently the most frequent cause of consultation at pediatric neurosurgical departments in Spain and other western countries. There is considerable confusion in the literature on the terminology and physiopathology of this deformity, as well as its differential diagnosis with true synostosis and treatment recommendations.

OBJECTIVES

To clarify these concepts and present a protocol for the management of positional plagiocephaly, which was recently requested by the Health Administration of the Community of Madrid.

PROTOCOL

The protocol aims to achieve coordination among pediatricians and neurosurgeons, as well as to provide precise information on this deformity for parents, pediatricians and neurosurgeons.

MATERIAL AND METHODS

Previous consensus was reached on a series of data. Infants were classified into three categories of deformity (mild, moderate, severe) according to measurements on digital photographs. Diagnosis and treatment follows two phases: a pediatric phase (up to 5 months of age) and a neurosurgical phase (from 5 months onwards). Infants are referred to neurosurgical consultation only after being treated with postural changes and physiotherapy and only after reaching the age of 5 months. The reasons for this approach are explained in the protocol, which also defines the functions and responsibilities of each specialty.

CONCLUSION

The treatment proposed in the protocol is staged, starting with postural changes and physiotherapy, followed by orthotic cranial devices and finally surgical treatment.

Posterior positional plagiocephaly treated with cranial remodeling orthosis

PRINCIPLES

Since the recommendation that infants sleep in the supine position, there has been an increase in cases of posterior positional plagiocephaly. Even though this condition is a purely cosmetic problem, if it is severe it may affect the child psychologically. Positioning may help in mild or moderate cases, but more active treatment may be necessary in severe cases.

METHODS

A prospective study of 260 children treated by dynamic orthotic cranioplasty for posterior positional plagiocephaly was conducted in Lausanne from 1995 to 2001. Construction of these cranial remodelling helmets is decribed in detail.

RESULTS

The treatment lasted 3 months on average, was effective, well tolerated, and had zero morbidity. The ideal period for initiating this therapy is between the ages of 4 and 6 months.

CONCLUSION

The remodelling helmet is a convincing option which can be recommended in infants with posterior positional plagiocephaly whose skull deformity is not satisfactorily corrected by physiotherapy. It should always be used before surgery is considered for patients with recognised positional plagiocephaly in the first year of life.

Deformational plagiocephaly associated with ocular torticollis: a clinical study and literature review

The etiology of craniofacial asymmetry secondary to positional plagiocephaly with or without concomitant congenital muscular torticollis has been well established. It has been proposed that the craniofacial asymmetry secondary to congenital superior oblique palsy involves a similar etiology. The causal relationship has been thought to be a result of the adoption of certain head and neck positioning, which predisposes the infant to develop preferential resting positions during supine sleep. We present a single subject with ocular torticollis and resulting plagiocephaly, and we distinguish the resultant craniofacial findings from those seen in patients with congenital muscular torticollis-associated deformational plagiocephaly. The distinctions that exist between the resultant asymmetries observed in ocular torticollis with superior oblique palsy and those found with congenital muscular torticollis suggest that the facial hemihypoplasia observed in conjunction with ocular torticollis may be the result of gravitational forces rather than compressive forces.

Nonsynostotic occipital plagiocephaly: factors impacting onset, treatment, and outcomes

BACKGROUND

Nonsynostotic occipital plagiocephaly remains a diagnosis of concern in infancy. This study evaluates factors affecting the onset, treatment, and outcomes of nonsynostotic occipital plagiocephaly.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Comparison of Infant Head Shape Changes in Deformational Plagiocephaly Following Treatment With a Cranial Remolding Orthosis Using a Noninvasive Laser Shape Digitizer

Deformational Plagiocephaly (DP) is a multi-planar deformity of the cranium occurring either pre-or postnatally in infants. In the last decade, the incidence of DP has increased substantially due to a number of factors, including supine sleeping positioning to reduce Sudden Infant Death Syndrome and the use of child carriers that increase supine positioning. Clinical questions persist about which children should be treated for DP and how to intervene, questions that are difficult to answer without accurate documentation of three-dimensional (3-D) head shape. This study explored a method for quantifying head shape and used that method to evaluate the success of orthotic treatment. Two hundred twenty-four infants who were diagnosed with DP received either a cranial remolding orthosis or a repositioning program with no orthotic intervention. Data from 25 head shape variables were collected using a noninvasive laser shape digitizer. Only variables attributable to growth showed significant differences in the control population, while the treatment population showed significant differences in pre-and post-treatment values for all variables. The study identified four variables as particularly important in assessing the head shape of infants with plagiocephaly: the cranial vault asymmetry index, radial symmetry index, posterior symmetry ratio, and overall symmetry ratio. Ninety-six percent or more of subjects in the treatment group showed improvement in each variable. These data document the utility of a 3-D scanning device and the effectiveness of treatment with a cranial remolding orthosis.

Positional plagiocephaly: pathogenesis, diagnosis, and management

Positional plagiocephaly is a deformation resulting from intrauterine constraint or postnatal positioning leading to asymmetrical cranial growth. There has been a steady increase in referrals for positional plagiocephaly following the release of the American Academy of Pediatrics recommendation of supine infant sleeping position to prevent Sudden Infant Death Syndrome (SIDS) in 1992, largely because of poor parent education on the risks of prolonged occipital pressures. While this deformity is fairly easy to manage when diagnosed early, treatment can become more difficult and complicated with prolonged course. Because of this, it is essential that primary care physicians and parents be educated on recognition of positional plagiocephaly, prevention strategies, and treatment options. In milder cases, where diagnosis is made early, the deformation can be managed by stretching exercises and regular prone positioning, while in more severe cases molding helmets may be needed. Following appropriate treatment, success rates for acceptable cranial shape may be as high as 92%.

A Pneumatic Orthotic Cranial Molding Helmet for Correcting Positional Plagiocephaly

The objective of this study was o determine the efficacy of a newly developed pneumatic orthotic cranial molding helmet for correcting positional plagiocephaly. The design was retrospective and the setting was a tertiary care center. Subjects were all patients in whom positional plagiocephaly has been diagnosed and who have been fitted by the Orthotics and Prosthetics Department for the helmet. Diagonal cranial lengths and widths were measured at each visit. Analysis included the calculation of the ratio change in oblique diameters compared with time, patient's age, and head circumference. Seventy-five patients met inclusion criteria (50 boys, 25 girls). Patients with pneumatic orthotic cranial molding helmet therapy had significantly improved outcomes as compared with pretreatment measurements (P < or = 0.0001). The helmet did not limit cranial growth as evidenced by significant normalization of the oblique measurement ratio when compared with increasing cranial circumference and age (P = 0.0003, P < or = 0.0001, respectively). The pneumatic orthotic cranial molding helmet successfully corrects positional plagiocephaly and does not hinder cranial growth.

Impacting infant head shapes

Infant sleep position impacts the development of head shape. Changes in infant sleep position, specifically the movement toward supine sleep, have led to a redefinition of normal head shape for infants in the United States. Historically, a dolichocephalic (elongated) head shape was the norm. Currently the norm has changed to a more brachycephalic (shorter and broader) shape. Since the American Academy of Pediatrics' Back to Sleep Campaign, the incidence of positional plagiocephaly has increased dramatically with a concurrent rise in the incidence of torticollis. Infants who require newborn intensive care, particularly premature infants, are more prone to positional plagiocephaly and dolichocephaly. Both can be prevented or minimized by proper positioning. The infant with an abnormal head shape requires careful evaluation; treatment varies according to the etiology. Craniosynostosis, a less common but pathological etiology for plagiocephaly, should be considered in the diagnostic process. Successful treatment of positional plagiocephaly and dolichocephaly includes systematic positioning changes to overcome the mechanical forces of repetitive positioning, physical and/or occupational therapy to treat underlying muscle or developmental challenges, and in some cases, molding helmet therapy.

Conservative interventions for positional plagiocephaly: a systematic review

This review aimed to synthesize current research evidence to determine the effectiveness of conservative interventions for infants with positional plagiocephaly. A systematic review was conducted, where papers were sourced from 13 library and internet databases. Research was included if published in English between 1983 and 2003. Level of evidence and quality of each paper was assessed to determine studies' magnitude of inherent bias. Results were synthesized in a narrative format and were considered with respect to homogeneity of participants, response rate, and outcome measures. Sixteen papers met inclusion criteria: 12 were case series and four were comparative studies. The methodological quality of the studies was moderate to poor, thus their results should be interpreted with caution. A consistent finding was that counterpositioning +/- physiotherapy or helmet therapy may reduce skull deformity; however, it was not possible to draw conclusions regarding the relative effectiveness of these interventions. Further investigation is required to compare the effect of helmet therapy with counterpositioning alone or when combined with physiotherapy. First, there is a need to develop an outcome measurement battery which incorporates psychometrically-sound measures from the perspectives of clinicians and patients.

[Systematic review of the effects of therapy in infants with the KISS-syndrome (kinetic imbalance due to suboccipital strain)]

OBJECTIVE

To establish the effects of manual therapy, chiropractic, or osteopathic treatment of the KISS-syndrome (kinetic imbalance due to suboccipital strain) in infants with positional preference, plagiocephaly, and colic.

DESIGN

Systematic review of the literature.

METHOD

PubMed, Embase and the Cochrane Library were searched for articles on the effects of manual therapy, chiropractic and osteopathy on the KISS-syndrome. Experts in the field of manual medicine and osteopathy were asked to provide relevant articles. The bibliography in a textbook of manual therapy for children was hand-searched for additional references to the KISS-syndrome.

RESULTS

No clinical trials were found that evaluated the effects of manual therapy or osteopathy on either the KISS-syndrome or its symptoms. Pooled analysis of two randomised clinical trials on the effects of chiropractic in infantile colic showed no statistically significant difference between active and control treatments. In addition, we found that 22% of infants showed short episodes of apnoea during manual therapy of the spine, and that one case has been described in which such apnoea resulted in death.

CONCLUSION

Given the absence of evidence of beneficial effects of spinal manipulation in infants and in view of its potential risks, manual therapy, chiropractic and osteopathy should not be used in infants with the KISS-syndrome, except within the context of randomised double-blind controlled trials.

Treatment of Recalcitrant Idiopathic Muscular Torticollis in Infants with Botulinum Toxin Type A

Congenital muscular torticollis (CMT) is the most common form of torticollis in children, significantly outnumbering orthopedic, neurologic, and ocular causes. CMT may present as a palpable sternomastoid tumor (SMT) or a simple tightness of the sternocleidomastoid muscle (SCM), designated as idiopathic muscular torticollis (IMT). Muscular torticollis has been associated with positional plagiocephaly in neonates who slept in the supine position. We have had difficulty in treating some of these combined cases by traditional methods such as physiotherapy, stretching exercises, and molding helmets. In November 2000, we began injecting botulinum toxin type A in cases in which there was persistent IMT, despite significant physical therapy input. The 15 patients included in this retrospective study all presented with IMT and positional plagiocephaly; all had responded poorly to conservative treatment, including physiotherapy, stretching exercises, or use of a helmet. In the attempt to avoid progression to surgical release, these patients were treated with botulinum toxin injected into the affected SCM and subsequent additional physiotherapy. All appeared to respond well, and a retrospective analysis of this treatment strategy was undertaken. Information gathered included a questionnaire, skull-shape tracings, and photographs. Independent outcome assessment data were then obtained from the regional child development teams and community physiotherapists. These results show that 14 of 15 children with recalcitrant IMT and positional plagiocephaly treated with botulinum toxin obtained sufficient improvement in neck range of motion and head position as to make surgical release of the muscle unnecessary. Our conclusion is that the use of botulinum toxin is a safe and effective adjunct to physical therapy in treating recalcitrant IMT; in selected cases, it may obviate the need for surgical release of a tight but nonfibrotic SCM.

Management of deformational plagiocephaly: repositioning versus orthotic therapy

OBJECTIVES

We compare positioning with orthotic therapy in 298 consecutive infants referred for correction of head asymmetry.

STUDY DESIGN

We evaluated 176 infants treated with repositioning, 159 treated with helmets, and 37 treated with initial repositioning followed by helmet therapy when treatment failed. We compared reductions in diagonal difference (RDD) between repositioning and cranial orthotic therapy. Helmets were routinely used for infants older than 6 months with DD >1 cm.

RESULTS

For infants treated with repositioning at a mean age of 4.8 months, the mean RDD was 0.55 cm (from an initial mean DD of 1.05 cm). For infants treated with cranial orthotics at a mean age of 6.6 months, the mean RDD was 0.71 cm (from an initial mean DD of 1.13 cm).

CONCLUSIONS

Infants treated with orthotics were older and required a longer length of treatment (4.2 vs 3.5 months). Infants treated with orthosis had a mean final DD closer to the DD in unaffected infants (0.3 +/- 0.1 cm), orthotic therapy was more effective than repositioning (61% decrease versus 52% decrease in DD), and early orthosis was significantly more effective than later orthosis (65% decrease versus 51% decrease in DD).

Deformational brachycephaly in supine-sleeping infants

OBJECTIVES

Medical dictionaries and anthropologic sources define brachycephaly as a cranial index (CI = width divided by length x 100%) greater than 81%. We examine the impact of supine sleeping on CI and compare orthotic treatment with repositioning.

STUDY DESIGN

We compared the effect of repositioning versus helmet therapy on CI in 193 infants referred for abnormal head shape.

RESULTS

Eighty percent of the infants had a pretreatment CI > 81%. Their initial mean CI at mean age 5.3 months was 89%, and after treatment, their mean CI was 87% (+/-2 SE = 0.9%) at mean age 9.0 months. For 92 infants with an initial CI at or above 90%, their initial mean CI of 96.1% was reduced to a mean of 91.9%.

CONCLUSIONS

Post-treatment CI was 86% to 88%, CI in neonates delivered by cesarean section was 80%, and CI in supine-sleeping Asian children was 85% to 91%, versus 78% to 83% for prone-sleeping American children. Repositioning was less effective than cranial orthotic therapy in correcting severe brachycephaly. We recommend varying the head position when putting infants to sleep.

Deformational plagiocephaly: diagnosis, prevention, and treatment

The "Back to Sleep" campaign has dramatically decreased the incidence of sudden infant death syndrome; however, its sequelae of deformational plagiocephaly have today reached epidemic proportions. In the last decade, we have learned to distinguish deformational plagiocephaly clinically from craniosynostosis, thereby preventing its unnecessary surgical correction. Primary care providers must increasingly be aware of this condition and, in turn, educate new parents about its prevention. Should preventative measures fail and infants develop persistent sleep patterns that result in craniofacial deformities, deformational plagiocephaly can be treated successfully with behavior modification or cranial molding-helmet therapy.

Dynamic orthotic cranioplasty: treatment of the older infant

The Dynamic Orthotic Cranioplasty Band is a cranial orthotic device used to treat deformational plagiocephaly in infants. The device works by applying a mild holding pressure to the most anterior and posterior prominences, where growth is not desired, while encouraging growth in adjacent flattened regions. Although this technique has been successfully used to treat infants as young as 3 months of age, it is often assumed that decreasing cranial growth and increasing cranial rigidity prohibit treatment in infants older than 1 year of age.

The authors' experience with older infants suggests the contrary. Through a series of case reports, they present evidence that this treatment remains viable during the 2nd year of life and that improvement has been observed in infants in whom treatment has been initiated as late as 18 months. These examples certainly suggest that additional prospective studies are warranted.

[Plagiocephaly in children: etiology, differential diagnosis and helmet treatment]

Plagiocephaly in a head-and-neck irradiated rat model or rhomboid-shaped head, occurs in at least 1 in 300 live births. In most cases such asymmetry is not caused by synostosis of the unilateral coronal or lambdoid sutures, but is rather a deformity produced by intrauterine and/or postnatal deformational forces. Categorization and diagnosis of plagiocephaly as synostotic or deformational is reliably made by physical examination and computerized tomography. Its differential diagnosis is extremely important because prompt surgical correction is usually indicated for the synostotic type. In contrast, infants with deformational frontal or occipital plagiocephaly generally respond to helmet treatment. 10 infants with significant deformational plagiocephaly were treated with individual plastic helmets during the past 2 years and 4 other infants with plagiocephaly are currently being treated. In each instance, cranial asymmetry dramatically improved as the brain grew and the head filled out the helmet. There were no significant complications. Awareness of deformational plagiocephaly allows more accurate diagnosis and appropriate treatment, avoiding unnecessary surgical intervention in patients with positional molding.
