Occurrence and Severity of Deformational Plagiocephaly in Infants: A Single Center Experience.

OBJECTIVE: To estimate the occurrence and severity of deformational plagiocephaly among infants. METHODS: A hospital-based, cross-sectional study was done in the pediatric ward of a tertiary care hospital between April 1, 2022 to October 31, 2022. Cranial Vault Asymmetry Index (CVAI) and Argenta Clinical Classification were applied to consecutive infants aged 1 month to 1 year till the calculated sample size was achieved. RESULTS: 67 infants were recruited and the occurrence of deformational plagiocephaly in the sample was estimated to be 46.3%. Level 2 severity of deformational plagiocephaly was the commonest, while as per the Argenta classification, majority belonged to type I (39.2%). Male gender and developmental delay were the significant risk factors for plagiocephaly with an odds ratio (95% CI) of 3.73 (1.23, 11.26) and 19.25 (2.31, 160.3), respectively. CONCLUSION: A high occurrence of deformational plagiocephaly was found in infants studied. There is a need for more studies to further corroborate these findings and study its associated factors.

Parental Education for the Prevention of Plagiocephaly.

INTRODUCTION: The American Academy of Pediatrics Back-to-Sleep Campaign significantly reduced infant mortality from sudden infant death syndrome. As a result of prolonged supine positioning, the incidence of deformational plagiocephaly has also risen 5-fold since its adoption. We aimed to improve the current educational paradigm for new parents with the goal of reducing the incidence of plagiocephaly within the confines of the Back-to-Sleep Campaign. We hypothesized that the early addition of plagiocephaly focused education for parents would reduce cephalic index, the ratio of head width to length, used as an easily measured objective proxy for positional plagiocephaly. METHODS: Children were screened at their newborn visit. Premature newborns and those diagnosed with craniofacial disorders were excluded. For those enrolled, biparietal and anteroposterior measurements of the head were obtained using manual calipers to obtain cephalic index. Subjects randomly assigned to the intervention group were shown a 2-minute video and given an educational pamphlet on methods to prevent plagiocephaly. Unpaired 2-sample t tests comparing mean differences in intervention and control were performed. RESULTS: Thirty-nine subjects were enrolled as of November 2023 with variable lengths of follow-up completed. The average baseline cephalic index for subjects in the control group was 82.7 and 83.8 for intervention group. Unpaired 2-sample t tests were performed at 2-, 4-, and 6-month time points to analyze the difference between groups. At 4 months, average cephalic index for subjects in the control and treatment group, respectively, was 90.6 and 83.4 (P = 0.02). SIGNIFICANCE: Parental education at the newborn visit led to decreases in cephalic index, a proxy for positional plagiocephaly, compared with control patients. This simple intervention has the potential to reduce parental stress and healthcare costs associated with the evaluation and treatment of plagiocephaly.

Prevalence and Severity of Positional Posterior Plagiocephaly and Positional Posterior Brachycephaly in Children and Adolescents in Japan.

This study aimed to assess the prevalence, severity, and natural history of positional posterior plagiocephaly (PPP) and positional posterior brachycephaly in Japan. We conducted a cross-sectional study of pediatric patients, ranging from 0 to 15 years old, evaluated for head trauma with negative computed tomography (CT) findings. The cranial vault asymmetry index (CVAI) was calculated using CT images at the superior orbital rim. Asymmetry according to CVAI values was subcategorized as follows: mild (3.5%-7%), moderate (7%-12%), and severe (>12%). The results were analyzed according to different age groups: group 1, 2-23 months (54 patients); group 2, 2-6 years (123 patients); and group 3, 7-15 years (123 patients). Overall, 300 patients were included (109 [36.3%] girls and 191 [63.7%] boys). The overall prevalence of PPP in the 300 patients was 46.7% (140 patients). PPP prevalence decreased consistently with age group: group 1, 57.4%; group 2, 47.2%; and group 3, 41.5%. Severe asymmetry was seen in all age groups. The overall mean cephalic index (CI) was 85.2. Cephalic index scores decreased consistently with age: group 1, 87.4; group 2, 85.1; and group 3, 84.3. The prevalence of PPP in Japan was higher than that reported in other countries. Although there was an overall decrease in the prevalence and severity of PPP with increasing patient age, PPP does not necessarily resolve spontaneously in all children. Furthermore, severe asymmetry was seen across all age groups.

Mustard Seed Pillow for Prevention of Deformational Plagiocephaly in ≤ 32 Weeks' Gestational Age Infants: An Open Label Randomized.

OBJECTIVES: To assess the effectiveness of using mustard seed filled pillows in preventing deformational plagiocephaly (DP) in premature infants. METHODS: A prospective open label randomized trial was conducted in a tertiary care hospital in South India. Eligible preterm infants born at ≤32 weeks and <1500 g admitted in the neonatal intensive care unit (NICU) were randomly allocated to the intervention and control groups. In addition to standard nesting, the intervention group was positioned using a mustard pillow, while the control group was positioned using nesting alone. Plagiocephaly was assessed using the Cranial Index (CI), Cranial Vault Asymmetry Index (CVAI) and Argenta classification within the first week and at 4 weeks postnatal age. RESULTS: Twenty-eight infants, each in the control and intervention groups, were included for analysis. At 4 weeks postnatal age, the intervention group had lower mean (SD) CVAI scores when compared to the control group [3.16 (1.89 vs 7.85 (2.63)] with adjusted odds ratio, aOR (95% CI) of 28.2 (3.8, 210.01), P < 0.01. More number of infants in the control group had plagiocephaly measured using Argenta classification [aOR (95% CI) 25.70 (2.80, 235.67), P < 0.01]. There were no differences in the Cranial Index scores in the intervention and control groups [aOR (95% CI) 0.41 (0.11, 1.52), P = 0.184]. CONCLUSION: A mustard seed pillow is an easily available and a cost-effective intervention for preventing plagiocephaly in hospitalized preterm infants.

Comorbidities of deformational plagiocephaly in infancy: A scoping review.

AIM: While deformational plagiocephaly (DP) is suspected to be associated with comorbidities, their nature and prevalence are unclear. This scoping review aims to report DP comorbidities occurring until the age of 2 years, their prevalence and whether they depend on the child's age and sex. METHODS: Relevant studies were identified by searching the Cochrane, MEDLINE, EMBASE, PubMed and EBSCO databases from 1992 to 30 April 2021. Data on study characteristics, comorbidities and assessment instruments were extracted and qualitatively synthesised. Risk of bias was assessed and studies with high risk of bias were excluded. RESULTS: Studies meeting selection criteria (n = 27) often evaluated groups from tertiary clinics, implying selection bias. Studies reported on developmental delay (n = 16), limited speech production (n = 1), auditory (n = 3), visual (n = 3), mandibular (n = 3) and neurological impairments (n = 1). The data did not allow prevalence calculation or modifying effect of sex. Due to biased data, the review provided no evidence on DP comorbidities. Weak evidence suggested that in the selective samples, DP was associated with motor and language delays in the first year. CONCLUSION: Due to biased data, no evidence on comorbidity in infants with DP was available. Our study underlined the need of risk of bias assessment in scoping reviews.

El pediatra y los padres en la toma de decisiones de tratamiento en plagiocefalia posicional: una revisión narrativa / The pediatrician and parents in treatment decision-making in positional plagiocephaly: A narrative review

La plagiocefalia posicional (PP) es una de las causas más frecuentes de consulta en neurocirugía pediátrica. La incidencia de PP aumentó en los '90, a partir de la campaña Dormir de espaldas. Junto con el aumento de la demanda de atención, se verifica un debate acerca de la eficacia de los distintos tratamientos. La interacción padres ­ pediatra orientada a elegir la mejor terapéutica adquiere importancia, particularmente cuando se trata de decisiones sensibles a la preferencia. Es necesario saber más acerca de la naturaleza de la toma de decisiones de tratamiento de PP, para contribuir al desarrollo de procesos decisorios eficaces. Se realizó una revisión narrativa sobre investigaciones en toma de decisiones de tratamiento en PP. Se identificaron artículos en PubMed y Google Scholar (1990 ­ 2022) en una búsqueda con los descriptores "plagiocephaly", "decision making" y "parents". Se incluyeron artículos cuyo tema central fuera la toma de decisiones en PP, o que la desarrollaran como parte de otro tema. Se excluyeron trabajos en los que la toma de decisiones aparece de modo secundario o tangencial. Se encontraron 3 artículos con distintos diseños metodológicos, en los que la severidad de la presentación, los elementos socioculturales y emocionales, y los aspectos relacionados con el tratamiento son los factores más implicados en la toma de decisiones. Las relaciones entre la ansiedad parental, las expectativas de tratamiento y la percepción subjetiva de la PP, y el rol del pediatra como proveedor de información válida y confiable son temas que necesitan de ulterior investigación (AU)

Positional plagiocephaly (PP) is one of the main reasons for consultation in pediatric neurosurgery. The incidence of PP increased in the 1990s, after the "Back to Sleep" campaign. Concurrently, the growing demand for care has led to a debate regarding the effectiveness of the different treatments. The parent-pediatrician interaction is aimed at choosing the best therapeutic approach becomes important, particularly when it comes to preference-sensitive decisions. There is a need to better understand the nature of PP treatment decision-making in order to contribute to the development of effective decisionmaking processes. In this narrative review, we evaluated the research on treatment decision-making in PP. Articles were identified in PubMed and Google Scholar (1990 - 2022) using the search terms "plagiocephaly", "decision-making" and "parents". Articles were included if their central theme was decision-making in PP, or if they developed it as part of another subject. We excluded articles in which decision-making appeared in a secondary or tangential way. Three articles were identified with different methodological designs, in which the severity of the presentation, sociocultural and emotional aspects, and aspects related to treatment were the factors most implicated in decision making. The relationships between parental anxiety, treatment expectations, subjective perception of PP, and the role of the pediatrician as a provider of valuable and reliable information are topics that require further investigation (AU)

[Current considerations in the management of positional plagiocephaly]. / Consideraciones actuales en el abordaje de la plagiocefalia posicional.

Since the American Academy of Pediatrics recommended the supine sleeping position for infants to prevent SIDS, positional plagiocephaly (PP) prevalence has increased. There are great controversies regarding the possible consequences of PP and the degree of severity required for them to manifest. There is no consensus on the efficacy of PP therapies, such as positioning, kinesiology, and cranial orthoses. This review aims to analyze the existing literature to update the causes, main characteristics, and evidence on the treatment of PP. Intervention from the newborn period is important, encompassing both prevention and management education, as well as early screening, evaluating the possible presence of congenital muscular torticollis, to start early treatment. The presence of PP can be a risk marker for psychomotor development.

Comparison of molding helmet therapy versus natural course in twins with nonsynostotic head deformation.

This observational study aims to compare the effectiveness of helmet therapy versus natural course in twin siblings suffering from nonsynostotic head deformations. A retrospective analysis of all twin couples treated with helmet therapy between March 2009 and May 2017 at an orthopedic hospital was conducted. Inclusion criteria were me if only one twin received helmet therapy. The other twin acted as control. A classification for different head shapes was used. A total of 61 twin couples was included. Change in outcome parameters of helmet therapy and natural course differed significantly: cranial vault asymmetry (CVA) -0.66 cm vs. -0.04 cm, cranial vault asymmetry index (CVAI) -5.35% vs. -0.51% (both p < 0.001), cephalic index (CI) -3.10% vs. -1.91% (p = 0.006). Helmet therapy showed a success rate (CI < 90% and CVAI ≤7% or better) of 63.6% vs. 21.1% in children with natural course (p = 0.002). Within the limitations of the study it seems that the results of this retrospective, single-center study confirm that helmet therapy to be a reliable treatment for mild to severe positional head deformation.

Another look at "tummy time" for primary plagiocephaly prevention and motor development.

It is three decades since it was recommended that infants sleep on the back to reduce risk of sudden unexpected infant death (SUID). The SUID prevention program is known as "back to sleep" or "safe sleeping", and this initiative is not questioned. Sleeping on the back is associated with, but not the cause of, the development of infant positional plagiocephaly, also known as deformational or a non-synostotic misshapen head when the skull sutures are open, not fused. This paper provides a synthesis of the history and impact of positional plagiocephaly. It includes a scoping review of plagiocephaly prevention facilitating motor development and reveals few articles on primary prevention which aims to prevent it developing in the first place. It is concerning that preschool-aged children with a history of infant plagiocephaly continued to receive lower developmental scores, particularly in motor development, than unaffected controls, and this may be a marker of developmental delay. Tummy-time (prone) for play is the mainstay of plagiocephaly prevention advice to minimize development of plagiocephaly and to facilitate infant motor development, particularly head control. While tummy-time has shown benefit for infant development, there is limited evidence of its effectiveness in preventing plagiocephaly and some evidence that it promotes only prone-specific motor skills. Most of the published literature is concerned with treatment post-diagnosis, in the form of reviews, or clinical notes. There is a plethora of opinion articles reinforcing tummy-time from birth for plagiocephaly prevention. The review shows that there are gaps in advice for early infant development of head control. An accepted test of head control in infants is "pull to sit" from supine which demonstrates antigravity strength of the neck flexors and coordination of the head and neck when the infant is drawn to sit from supine. This motor skill was cited as achievable by 4 months in the earliest paper on plagiocephaly in 1996. Physical therapists and others should revisit the mechanism of early infant head control development against gravity, particularly antigravity head, neck and trunk coordinated flexion movement in supine, as there has been little attention to early facilitation of this motor skill as a plagiocephaly prevention strategy. This may be achieved by considering "face time" as well as tummy time for primary prevention of plagiocephaly.

[Follow-up and prognostic study of infants with positional plagiocephaly]. / å©´å„¿ä½“ä½æ€§æ–œå¤´å¼‚å¸¸çš„éšè®¿å’Œé¢„åŽç ”ç©¶.

OBJECTIVES: To study the effects of infantile positional plagiocephaly on the growth and neural development. METHODS: A retrospective study was conducted on the medical data of 467 children who underwent craniographic examination and were followed up to 3 years of age in Peking University Third Hospital from June 2018 to May 2022. They were divided into four groups: mild positional plagiocephaly (n=108), moderate positional plagiocephaly (n=49), severe positional plagiocephaly (n=12), and normal cranial shape (n=298). The general information of the four groups and the weight, length, head circumference, visual acuity screening results, hearing test results, and the scores of Pediatric Neuropsychological Developmental Scales/Gesell Developmental Schedules of the four groups from 6 to 36 months old were compared. RESULTS: The rates of adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping posture in the mild, moderate, and severe positional plagiocephaly groups were higher than the normal cranial group (P<0.05). There was no significant difference in weight, length, and head circumference among the four groups at 6, 12, 24 and 36 months of age (P>0.05). The incidence rate of abnormal vision in the severe positional plagiocephaly group was higher than that in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups at 24 and 36 months of age (P<0.05). The scores of the Pediatric Neuropsychological Developmental Scales at 12 and 24 months of age and the scores of the Gesell Developmental Schedules at 36 months of age in the severe positional plagiocephaly group were lower than those in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups, but the difference was not statistically significant (P>0.05). CONCLUSIONS: Adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping position may be associated with infantile positional plagiocephaly. Mild or moderate positional plagiocephaly has no significant impact on the growth and neural development of children. Severe positional plagiocephaly have adverse effects on the visual acuity. However, it is not considered that severe positional plagiocephaly can affect the neurological development.

Denominator of Cranial Vault Asymmetry Index: Choosing Between Longer and Shorter Diagonal Lengths.

Since it was proposed in this journal in 2001, the cranial vault asymmetry index (CVAI) has been an important parameter for assessing cranial shape. However, different publications currently use different variables in the denominator of the CVAI formula. We thus investigated the use of long and short diagonal lengths as variables in the denominator of the CVAI formula. We searched the databases of PubMed, Google Scholar, and Scopus for articles published between 2016 and 2022 that cited the original work article of CVAI. Articles were included if they were written in English and if the denominator of the CVAI formula was specified. For multiple articles by the same author, only the most recent article was included. In total, 30 articles were included; 10 articles used the longer diagonal length as the denominator and 20 articles used the shorter diagonal length. No uniform trend was observed by a country or journal of publication. Application of the CVAI formula using different denominators yielded interchangeable results, and the resulting values had only negligible differences clinically. However, it would be necessary to create a standard formula for using the CVAI as a parameter for reporting cranial shape assessments consistently.

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. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Molding Helmet Therapy for Severe Deformational Brachycephaly: Position of Eurion and Therapeutic Effect.

BACKGROUND: Molding helmet therapy is used routinely for moderate to severe deformational plagiocephaly. However, there have been few reports of its use for deformational brachycephaly (DB). The incidence and severity of DB are high in the Asian population, including Japanese people, but there are no reports of treatment for severe cases. The current study showed significant improvement even in severe DB with various deformities. The difference in improvement according to the morphologic classification was investigated. METHODS: The study included 47 patients treated with helmet therapy for DB with a cephalic index of greater than 100%. Three-dimensional head scans were used for classification and measurement. DB was classified into four types according to the position of the eurion and the presence of deformational plagiocephaly. The therapeutic effect was determined by changes in cephalic index and cranial asymmetry. RESULTS: Patients exhibited a mean change of 8.0% in cephalic index and 6.4 mm in cranial asymmetry. An older age at initiation was associated with less change in both cephalic index and cranial asymmetry. A significant difference in the amount of cephalic index change was observed depending on the position of the eurion when the starting age was 6 months or older ( P < 0.05). CONCLUSIONS: Molding helmet therapy for severe DB results in significant morphological improvement. However, depending on the position of the eurion, the effect of treatment may be decreased if it is started too late. It is necessary to understand the difference in improvement depending on the morphology and to ensure early intervention. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Role of State Insurance Policy in Orthotic Helmet Access for Deformational Plagiocephaly.

BACKGROUND: Helmet therapy for deformational plagiocephaly has an ideal window for treatment, and timely access to care is vital to achieving optimal benefit. The authors evaluated the hypothesis that patients insured through Medicaid experience decreased access to helmet therapy. METHODS: This was a retrospective analysis of referrals for helmet therapy to Cranial Technologies, Inc. between 2014 and 2020 across 21 states. Outcome measures were likelihood of receiving a helmet, receiving a second helmet, receiving delayed treatment, and having delayed presentation. RESULTS: From 2014 to 2020, a total of 219,869 patients were referred and 141,513 of these received a helmet. Patients with Medicaid were less likely to receive treatment (OR, 0.63; P < 0.001) and more likely to present late (OR, 1.55; P < 0.001) or receive delayed treatment (OR, 3.24; P < 0.001) compared with the commercially insured. Patients with Medicaid were less likely to receive helmet therapy in nine states, with the strongest association in Texas (OR, 0.32; P < 0.001), and more likely to receive helmet therapy in five states, with the strongest association in Colorado (OR, 1.89; P < 0.001). Medicaid was associated with late presentation and delayed treatment in all states. CONCLUSIONS: Patients with Medicaid presented later and were less likely to receive helmet therapy. Findings reflected state-specific Medicaid policies, with patients in some states more likely to receive a helmet with Medicaid than with commercial insurance. However, late presentation and delays in treatment with Medicaid were observed across all states. State-specific Medicaid restrictions are likely a driving factor in determining access to helmet therapy.

Positional Plagiocephaly and Craniosynostosis.

Along with the decrease in sudden infant death syndrome due to the successful "Back to Sleep" Campaign, there was a reciprocal increase in cases of positional plagiocephaly (PP). The prevalence of PP significantly rose from approximately 5% to upward of 46% at age 7 months. Consequently, clinicians have seen a surge in the number of patients presenting with head shape abnormalities. Not only does this increase in patient volume pose a logistical problem to clinics, but it also poses a potential risk to patients with craniosynostosis, whose head shape anomalies are similar to a "needle in a haystack" of patients with more common PP. This review explores the causes, risk factors, and treatment options of PP and craniosynostosis, along with the differential of head shape anomalies based on phenotypic presentation. In doing so, we hope to provide pediatric care clinicians with the tools necessary to effectively evaluate and manage patients with head shape abnormalities. [Pediatr Ann. 2023;52(1):e10-e17.].

Barriers and facilitators influencing parental adherence to prevention strategies for deformational plagiocephaly: Results from a scoping review.

BACKGROUND: Deformational plagiocephaly can be prevented in many healthy infants if strategies are implemented early after birth. However, despite efforts to disseminate accurate information, parental adherence to evidence-based prevention strategies is a challenge. To date, factors - barriers and facilitators - influencing parental adherence to strategies have yet to be identified in a comprehensive manner. OBJECTIVES: This scoping review aims to identify and synthesize current evidence on barriers and facilitators impacting adherence of parents of newborns to deformational plagiocephaly prevention strategies. METHODS: This review followed the Joanna Briggs Institute (JBI) process guidelines. Seven electronic (Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, SPORTDiscus, Academic Search Complete, AMED, PsychINFO and Scopus) and two grey literature (Health Systems Evidence and Grey Literature Report) databases were searched. Studies published between 2001 and 2022 were included. The deductive thematic data analysis used was guided by the Capability, Opportunity, Motivation Behavioral Model (COM-B) of health behaviour change. RESULTS: From a total of 1172 articles, 15 met the eligibility criteria. All components of the COM-B framework were identified. Capability-psychological and opportunity-environmental factors dominated the literature, whereas capability-physical, motivation and, in particular, opportunity-social factors were understudied. The most often reported barriers were a lack of knowledge of deformational plagiocephaly and the associated prevention strategies, ambiguous or inconsistent messaging, intolerance of babies to prone positioning and a lack of time. The most frequently reported facilitators were an awareness of deformational plagiocephaly, postural asymmetry and prevention strategies, skill acquisition with practice, accurate convincing information, scheduled time and environmental organization to position the baby at home. DISCUSSION: Recommendations focused on diffusing accurate and detailed information for parents. Our review also suggests a gap regarding the comprehensive identification of factors influencing parental adherence to deformational plagiocephaly prevention strategies. Further studies exploring comprehensive opportunity-social and motivation factors influencing parental adherence to deformational plagiocephaly prevention strategies are warranted to inform prevention programmes and foster better infant outcomes.

Disparities in Access to Cranial Remodeling Orthosis for Deformational Plagiocephaly.

OBJECTIVE: Moderate to severe cases of deformational plagiocephaly (DP) may be treated with cranial remolding orthoses (CRO). This study investigated the socioeconomic disparities in access to care for CRO for DP correction. DESIGN: This was a retrospective review of medical records from a single CRO company in Connecticut from 2014 to 2020. METHODS: Demographic variables were collected from all patients. Univariable logistic regressions were used to identify differences for presenting age at consultation, whether CRO was pursued, and length of CRO treatment by insurance payor and household income quartile. RESULTS: Of the 5620 patients identified, 4100 (73.0%) received CRO, with 674 (12.0%) receiving a second helmet. Of those receiving CRO, 1536 (37.5%) had Medicaid insurance while 2558 (62.4%) were commercially insured. Patients on Medicaid were 1.30 times more likely to have delayed presentation (P = .017), while patients from the lowest income quartile were 1.26 1.50 (P < .001) and 1.58 (P < .001) times more likely to have a delayed presentation relative to those in the highest and second-highest income quartiles, respectively. Patients in the highest and second-highest income quartiles were also 1.55 (P < .001) and 1.45 (P < .001) more likely, respectively, to receive CRO after consultation than those from the lowest income quartile. CONCLUSIONS: Lower income and Medicaid-insured patients had delayed presentation for CRO consultation. Those from the lowest income quartile were more likely to never receive CRO than those from wealthier backgrounds. Low socioeconomic status and Medicaid insurance, which can have more restrictive coverage policies for CRO, may result in the delayed treatment of DP.

Ultrasonography as first line imaging for the diagnosis of positional plagiocephaly.

BACKGROUND: In the last years, numerous studies evaluated different tools for the diagnosis of positional plagiocephaly (PP). The purpose of this study was to evaluate ultrasonography (US) as a first line screening test of lambdoid sutural patency in child with PP and to compare our results with the literature. METHODS: All consecutive patients who referred to our Institute from January 2016 to October 2017 with the suspicion of PP, were included in the study and performed US examination of the lambdoid sutures. A 3-6-month clinical follow-up was performed by a pediatric neurosurgeon or a pediatrician to confirm the diagnosis of PP. RESULTS: Thirty-five children performed US examination and in all cases the diagnosis of PP was confirmed. No cases of anticipated suture fusion were examined during this period. The concordance between US findings and clinical exam follow-up was 100%. CONCLUSIONS: Ultrasonography of the lambdoid sutures represents an ideal first-line screening test and reliable alternative to other diagnostic techniques for lambdoid sutural patency in child with PP, being radiation free, fast and cheap.

UCSQ Method Applied on 3D Photogrammetry: Non-Invasive Objective Differentiation Between Synostotic and Positional Plagiocephaly.

OBJECTIVE: Objective differentiation between unilateral coronal synostosis (UCS) and positional posterior plagiocephaly (PPP) based on 3D photogrammetry according to Utrecht Cranial Shape Quantificator (UCSQ). DESIGN: Retrospective study. SETTING: Primary craniofacial center. PATIENTS, PARTICIPANTS: Thirty-two unoperated patients (17 UCS; 15 PPP) (age < 1 year). INTERVENTIONS: Extraction of variables from sinusoid curves derived using UCSQ: asymmetry ratio forehead and occiput peak, ratio of gradient forehead and occiput peak, location forehead and occiput peak. MAIN OUTCOME MEASURE(S): Variables, derived using 3D photogrammetry, were analyzed for differentiation between UCS and PPP. RESULTS: Frontal peak was shifted to the right side of the head in left-sided UCS (mean x-value 207 [192-220]), and right-sided PPP (mean x-value 210 [200-216]), and to the left in right-sided UCS (mean x-value 161 [156-166]), and left-sided PPP (mean x-value 150 [144-154]). Occipital peak was significantly shifted to the right side of the head in left-sided PPP (mean x-value 338 [336-340]) and to the left in right-sided PPP (mean x-value 23 [14-32]). Mean x-value of occipital peak was 9 (354-30) in left- and 2 (350-12) in right-sided UCS. Calculated ratio of gradient of the frontal peak is, in combination with the calculated asymmetry ratio of the frontal peak, a distinctive finding. CONCLUSIONS: UCSQ objectively captures shape of synostotic and positional plagiocephaly using 3D photogrammetry, we therefore developed a suitable method to objectively differentiate UCS from PPP using radiation-free methods.
