RESUMO
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.

OBJECTIVE: To investigate the correlation between positional skull deformation (PD) and motor performance of infants under 4 months of age. METHODS: Infants aged under 4 months were enrolled in the children's healthcare and the premature infants follow-up Clinic of the Second Affiliated Hospital of Army Military Medical University. The cranial vault asymmetry (CVA) and cephalic index (CI) were calculated in all infants, and the infant motor performance test (TIMP) was used to evaluate the infant motor performance. The motor performances of infants with different types and degrees of PD were compared, so were the incidences of PD in infants with different motor performance levels. RESULTS: Overall, 2118 infants were recruited and divided according to the types of PD and TIMP scores. The comparison of TIMP scores within different types of PD at different months of age showed that, regardless of the types of PD, TIMP scores of infants with PD were lower than those of normal infants. In particular, the difference in TIMP scores was statistically significant (P < 0.05) in infants with dolichocephaly, plagiocephaly,dolicho-plagiocephaly and brachy-plagiocephy. In addition, the comparison of CVA values of infants with different TIMP score levels at different months of age showed that the CVA values of the extremely low-level group were significantly higher than those of the medium-level and high-level group, especially in the 3-month-old and 4-month-old groups, which showed significant statistical differences (P < 0.05). CONCLUSIONS: PD and motor performance of infants aged under 4 months seem to interact and influenc each other. The more serious the severity of PD were,the worse the motor performance of infants. Conversely, the incidence of PD increased in infants with poor motor performance.

Deformational plagiocephaly and brachycephaly, or abnormal flattening of the infant skull due to external forces, are often managed with orthotic helmet therapy. Although helmet therapy is widely used, the factors that predict poor outcomes are not well characterized. In this study of over 140,000 patients who received helmet therapy, older age and greater severity at presentation, and noncompliance with treatment were each independently associated with worse craniometric and provider-reported outcomes. Each additional point of cranial vault asymmetry index or cephalic index at a presentation is associated with an increased likelihood of residual brachycephaly at completion [odds ratio (OR): 1.067; 95% Cl: 1.058-1.075; P <0.0001 and OR: 2.043; 95% CI: 2.021-2.065; P <0.0001, respectively], whereas each additional point of cranial vault asymmetry index at a presentation associated with increased likelihood of residual asymmetry at completion (OR: 2.148; 95% Cl: 2.118-2.179; P <0.0001). Patients were more likely to have residual brachycephaly or asymmetry with increasing age at treatment initiation (OR: 1.562; 95% CI: 1.524-1.600; P <0.0001 and OR: 1.673; 95% Cl: 1.634-1.713; P <0.0001, respectively, for each additional month of age at initiation). These results highlight a need for prompt referral for helmeting, especially in cases with severe features or when patients present late to care. Potentially modifiable factors are age at helmeting and compliance with treatment protocols, and consideration of these factors may be important for achieving success in some cases.

Implementation of the Utrecht Cranial Shape Quantificator (UCSQ) classification method on 3D photogrammetry in patients with different types of craniosynostosis is the aim of the present study. Five children (age <1 year) of every group of the common craniosynostoses (scaphocephaly, brachycephaly, trigonocephaly, right-sided and left-sided anterior plagiocephaly) were randomly included. The program 3-Matic (v13.0) was used to import and analyze the included 3dMD photos. Three external landmarks were placed. Using the landmarks, a base plane was created, as well as a plane 4 cm superior to the base plane. Using UCSQ, we created sinusoid curves of the patients, the resulting curves were analyzed and values were extracted for calculations. Results per patient were run through a diagnostic flowchart in order to determine correctness of the flowchart when using 3D photogrammetry. Each of the patients (n=25) of the different craniosynostosis subgroups is diagnosed correctly based on the different steps in the flowchart. This study proposes and implements a diagnostic approach of craniosynostosis based on 3D photogrammetry. By using a diagnostic flowchart based on specific characteristics for every type of craniosynostosis related to specific skull deformities, diagnosis can be established. All variables are expressed in number and are therefore objective.

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.

BACKGROUND: Craniosynostosis is a condition characterized by the premature fusion of 2 or more skull bones. Craniosynostosis of the lambdoid suture is one of the rarest forms, accounting for 1-4% of all craniosynostoses. Documented cases are separated into simple (single suture), complex (bilateral), and associated with adjacent synostoses ("Mercedes Benz" Pattern) or syndromes (i.e., Crouzon, Sathre-Chotzen, Antley-Bixler). This condition can manifest phenotypic deformities and neurological sequelae that can lead to impaired cognitive function if improperly treated or left undiagnosed. Preferred surgical techniques have varied over time but all maintain the common goals of establishing proper head shape and preventing of complications that could contribute to aforementioned sequelae. SUMMARY: This comprehensive review highlights demographic distributions, embryological development, pathogenesis, clinical presentation, neurological sequelae, radiologic findings, surgical techniques, surgical outcomes, and postoperative considerations of patients with lambdoid craniosynostosis presentation. In addition, a systematic review was conducted to explore the operative management of lambdoid craniosynostosis using PubMed, Embase, and Scopus databases, with 38 articles included after screening. Key Messages: Due to a low volume of published cases, diagnosis and treatment can vary. Large overlap in presentation can occur in patients that display lambdoid craniosynostosis and posterior plagiocephaly, furthering the need for comprehensive analysis. Possessing the knowledge and tools to properly assess patients with lambdoid craniosynostosis will allow for more precise care and improved outcomes.

ABSTRACT: Plagiocephaly patients generally undergo corrective surgery in the first years of life, but during their growth malformative sequelae become apparent and can have a negative psychological and social impact. Volumetric filling techniques have been used to improve social balance and minimize such negative effects.We present a case of a 25âyears old male with a history of plagiocephaly corrected by 8âmonths of age. He kept a bilateral frontotemporal defect and we performed a lipofilling of the affected areas. The aesthetic results were very satisfactory and 6âmonths and 1âyear after the procedure he maintained a good volumetric filling. There were no complications during or after the procedure.Lipofilling provides good contouring results and has low complication rates. Its major inconvenient is adipose tissue resorption.As illustrated by this case, this type of treatment significantly improves facial appearance, raising patients' self-esteem and quality of life.

Unilateral lambdoid synostosis is the rarest form of craniosynostosis. Surgical correction is technically challenging from a morphological standpoint and is used to decompress intracranial pressure. Herein, the authors present a "rotational advancement bone flap" technique for the repair of posterior plagiocephaly. A bicoronal skin incision was performed, to expose the occipital region. The rotational advancement bone flap was designed to hinge off the nonsynostotic side, and it was set up to include an occipital protrusion on the normal side. On the premature side, an advancement bone flap was set up to include the flattened and deformed occipital bone. A titanium cranial distractor, which was attached between the bone flap and the anterior bone. An absorbable plate, which would later become a hinge due to the movement of the bone flap, was attached to the area for reinforcement. The authors technique was able to decompress intracranial pressure with satisfactory esthetic outcomes.

ABSTRACT: Non-syndromic craniosynostosis (NSCS) is a disease, in which a single cranial bone suture is prematurely fused. The early intervention of the disease is associated with a favorable outcome at a later age, so appropriate screening of NSCS is essential for its clinical management. The present study aims to develop a classification and detection system of NSCS using skull X-ray images and a convolutional neural network (CNN) deep learning framework. A total of 56 NSCS cases (scaphocephaly [ n = 17], trigonocephaly [n = 28], anterior plagiocephaly [n = 8], and posterior plagiocephaly [n = 3]) and 25 healthy control infants were included in the study. All the cases underwent skull X-rays and computed tomography scan for diagnosis in our institution. The lateral views obtained from the patients were retrospectively examined using a CNN framework. Our CNN model classified the 4 NSCS types and control with high accuracy (100%). All the cases were correctly classified. The proposed CNN model may offer a safe and high-sensitivity screening of NSCS and facilitate early diagnosis of the disease and better neurocognitive outcome for patients.

BACKGROUND: Positional head deformity (PHD) is defined as a change in the shape of an infant's skull due to an external force. In certain cases, it can lead to cosmetic deformities or even neurological issues due to its impact on the developing nervous system. Therefore, we conducted this study to investigate the incidence and characteristics of PHD in term infants in China and preliminarily establish a localized diagnostic reference standard. METHODS: Overall, 4456 term infants from three medical institutions in Chongqing were and divided and analyzed according to their age. Cranial vault asymmetry (CVA) and cephalic index (CI) were calculated in all infants. The current international diagnostic criteria were used to understand PHD incidence and analyze the CVA and CI distribution. RESULTS: According to the current international standards, the total detection rate of PHD in Chongqing's term infants was 81.5%, with brachycephaly alone being the most frequent (39.4%), followed by brachycephaly with plagiocephaly (34.8%) and plagiocephaly alone (6.2%). The detection rates of dolichocephaly were low: alone, 0.9% and combined with plagiocephaly, 0.2%. According to age, plagiocephaly (44.5%) and brachycephaly (82.0%) were the most frequent in the 2-3-month group. The 75th/90th/97th and 3rd/10th/25th/75th/90th/97th percentiles of CVA and CIs were 0.4/0.7/1.0 and 76.4/78.8/82.3/91.1/94.6/99.2%, respectively. CONCLUSIONS: According to the current international standards, the PHD detection rate among term infants in Chongqing was high. Therefore, a new diagnostic standard for Chinese infants was proposed where CVA ≥ 0.4 cm indicates plagiocephaly, CI ≥ 91% indicates brachycephaly, and CI ≤ 82% indicates dolichocephaly.

PURPOSE: Posterior plagiocephaly (PP) is a common clinical condition in pediatric age. There are two main causes of PP: postural plagiocephaly and craniosynostosis. Early diagnosis is important, as it prevents neurological complications and emergencies. Diagnosis in the past was often made late and with imaging tests that subjected the infant to a high radiation load. Suture ultrasound does not use ionizing radiation; it is easy to perform, allows an early diagnosis, and directs toward the execution of the cranial 3D-CT scan, neurosurgical consultation, and possible intervention. The aim of the study is to describe the high sensitivity and specificity of suture ultrasound for the differential diagnosis between plagiocephaly and craniosynostosis. METHODS: We reported our prospective experience and compared it with the data in the literature through a systematic review. The systematic review was conducted on electronic medical databases (PubMed, Embase, Cochrane Library, Scopus, and Web of Science) evaluating the published literature up to November 2020. According to Preferred Reporting Items for Systematic Reviews and Meta-ANALYSES (PRISMA statement), we identified 2 eligible studies. Additionally, according to AMSTAR 2, all included reviews have been critically rated as high quality. A total of 120 infants with abnormal skull shape were examined in NICU. All underwent clinical and ultrasound examination. RESULTS: Of the total, 105 (87.5%) had plagiocephaly and 15 dolichocephaly/scaphocephaly (12.5%). None of these had associated other types of malformations and/or neurological disorders. The synostotic suture was identified ultrasonographically in 1 infant and subsequently confirmed by 3D CT scan (100%). CONCLUSION: Cranial sutures ultrasonography can be considered in infants a selective, excellent screening method for the evaluation of skull shape deformities as first technique before the 3D CT scan exam and subsequent neurosurgical evaluation. Cranial suture ultrasonography should be considered part of clinical practice especially for pediatricians.

Positional plagiocephaly is the most common cause of cranial asymmetry. Deformational brachycephaly denotes a head shape characterized by occipital flattening and increased bilateral width, which can also be caused by external deformation of the moldable infant cranium in positional bilateral posterior plagiocephaly. There are reports of craniosynostosis associated with Chiari I malformation (CIM), possibly caused by decreased posterior fossa volume and related to increased intracranial pressure. To the best of our knowledge, this is only the second case report demonstrating acquired CIM in a child with positional brachycephaly. Of note, the fact that the CIM resolved after helmet therapy could support the hypothesis that CIM is associated with decreased volume of the posterior fossa. However, these two conditions may be independent of one another. More research is needed to identify an association between the two conditions.

INTRODUCTION: Brachycephaly and anterior and posterior plagiocephaly appear as an isolated entity or manifest in syndromic conditions. In severe cases, possible treatment options currently comprise either cranioplasty or osteogenetic distraction. The aim of this paper is to retrospectively review the perioperative course of a series of children treated by posterior meander expansion technique at our institution with focus on the course of postoperative intracranial volume and eventual tonsillar descent evolution. METHODS: Forty-two children received a posterior cranial vault remodeling by means of a posterior meander technique during a 7-year period. Hospital records were reviewed, and pre- and postoperative MRIs were analyzed for intracranial volume, cephalic and asymmetry index, and tonsillar position over time. RESULTS: Median age at surgery was 11.5 months (range 17 days-10 years). Nineteen children had a symmetrical cranial deformity, twenty-three an asymmetrical synostosis. Half of the cohort showed a syndromic condition. Transfusions were administered in the majority (92.2%) of the cases. A significant postoperative increase of intracranial volume was present from 1188.9 ± 370.4 cm3 to 1324.8 ± 352.9 cm3 (p < 0.001). The asymmetry index showed a significant improvement postoperatively: 0.86 ± 0.06 versus 0.91 ± 0.05 (p < 0.001), while the cephalic index showed a non-statistical change (0.91 ± 0.11 versus 0.88 ± 0.08). Tonsillar herniation, bilateral or homolateral, showed no significant changes at early control, while a nonsignificant amelioration of tonsillar descent was seen among children older than 12 months at late imaging follow-up. CONCLUSION: Among the osteoplastic techniques, the posterior meander technique offers several advantages, such as early mobilization of the child, less bony defects, absence of implants, and a small complication rate. However, further comparative studies among different surgical techniques are needed.

PURPOSE: The aim of this study was to show the displacements and strain induced by the supraorbital band advancement during a craniofacial surgery for an anterior plagiocephaly on the orbital bones and the orbital content thanks to a numerical surgical simulation using the finite element method. METHODS: A three-dimensional (3D) finite element model of a child with an anterior plagiocephaly was entirely created from a tomodensitometry of a patient followed by our Craniofacial Pediatric team. Data of the tomodensitometry were computed with Slicer 3D to re-create the orbit geometry. Mesh production, properties of the model, and simulations of the fronto-orbital advancement were conducted on Hyperworks software (Altair Engineering, Inc., Detroit, MI, USA). RESULTS: The resulting 3D Finite Element Model was used to perform the supraorbital advancement simulation. Displacement and strain patterns were studied for orbital bones, oculomotor muscles, and eyeballs. Relative high strain in the both trochlear area and excycloration of the right orbit are among the most interesting results as torsional strabismus as V-pattern strabismus are often described in children with an anterior plagiocephaly. CONCLUSIONS: This pediatric Finite-Element Model of both orbits of a child with an anterior plagiocephaly showed the impact of the fronto-orbital advancement on the oculomotor system. This model described the relationship between the craniofacial surgery and the strabismus in the unilateral coronal synostosis. The advantages of this model are the many opportunities for improvement, including postoperative period and additional surgical procedures.

ABSTRACT: During the last 3 decades, the incidence of positional plagiocephaly and brachycephaly has increased. Treatment options are conservative and can include physiotherapy and molding helmet therapy. The decision to start therapy is based on patient history and subjective assessment of cranial shape by the physician and the parents. To determine the impact of these deformations on esthetic self-worth, as well as cranial shape, this study was conducted on a population of adult bald men.Participants were asked to fill in a questionnaire about the amount of comments received on cranial shape, as well as grade their general esthetic and grade craniofacial features using a visual analogue scale. The cranial proportions and symmetry were measured using plagiocephalometry.50 adult bald men were included in this study. The prevalence of nonsynostotic plagiocephaly was 12%; the prevalence of nonsynostotic brachycephaly was 0%. No significant correlation was found between plagiocephaly or brachycephaly, cranial circumference, width or length and amount of comments on cranial shape, cosmetic assessment of appearance or cosmetic assessment of cranial shape. On average, teeth and eyes were given the highest cosmetic value, eyebrows and chin were given the lowest scores.Cranial shape does not have a significant impact on the amount of comments received on cranial shape, nor the cosmetic assessment of either overall appearance or cranial shape in bald men. For bald men, eyes and teeth are more important craniofacial features in cosmetic assessment. There is no clear esthetic need to treat deviating cranial shape with helmet therapy in male patients.

BACKGROUND: Complications of cranial distraction techniques can arise perioperatively. This study assessed long-term clinical outcomes following cranial distraction for craniosynostosis. We analyzed factors involved in those complications. METHODS: We retrospectively assessed outcomes from 120cases treated with cranial distraction for craniosynostosis between 1997 and 2019. Age at surgery, type of craniosynostosis, length of advancement, and complications were reviewed. We analyzed cases in which clinical characteristics and medical data appeared to increase the risk of complications. RESULTS: Of the 120 patients (65 males, 55 females), 79 had syndromic craniosynostosis and 41 had nonsyndromic craniosynostosis. Type of craniosynostosis was scaphocephaly in 17 patients, trigonocephaly in 4, plagiocephaly in 15, brachycephaly in 57, oxycephaly in 14, cloverleaf in 10, and others in 3. Mean age at surgery was 18.6 months (range, 3-525 months). Mean total length of advancement was 32.3 mm (range, 5.5-62.0âmm). No deaths were encountered. Complications included cerebrospinal fluid leaks in 5 patients, epidural abscess in 1, local infections in 33, device problems in 20, erosions and/or ulcers in 23 and decubitus ulcers in 8.Comparisons of complications and factors: Local infection showed no significant correlation with type of craniosynostosis, nor with the total length of advancement. Plate displacement showed significant relationships with total length of advancement, or with age at surgery (Pâ<â0.01). CONCLUSION: These results suggested that local infection occurred independent of the type of craniosynostosis. Plate displacement and ulcers appear to occur more easily among patients with longer lengths of advancement or with surgery at a younger age, due to the weakness of the cranial bones.

ABSTRACT: In the last 3 decades, the incidence of positional cranial deformations in infants, such as positional plagiocephaly and positional brachycephaly, has increased. The deviating shape often causes parental concern for the later psychosocial wellbeing of the child. Treatment options are nonoperative, varying from positional change to helmet therapy, of which the effect has often been debated. Multiple risk factors have been associated with an increased risk on the development of these deformations. The goal of this study was to assess the impact of known risk factors on the type and severity of resulting positional cranial deformation.Parents were asked to fill out a questionnaire regarding the presence of risk factors, such as gender, age, pregnancy duration, method of delivery and reasons for atypical deliveries, breech position, birth weight, developmental status, positional preference, family history, number of siblings, and torticollis presence. Treatment methods were documented and plagiocephalometry was used to measure the cranial proportions. All children were invited to participate in short-term follow-up. The significance of the risk factors and the effect of different kinds of therapy are discussed. Although no significant correlation was found between severity and risk factors, some risk factors could be correlated with the kind of positional cranial deformation. Of the different therapies, helmet therapy had a significant impact on the reduction of positional plagiocephaly.

PURPOSE: The current assessment of patients with craniofacial asymmetries is accomplished by physical examination, anamnesis and radiological imaging. We propose a semi-automated, computer-assisted craniofacial evaluation (SymMetric v 1.0) based on orthogonal photography of the patient's head in 3 positions. The system is simple, low-cost, no-radiation or special resources needed. Although it does not substitute CT in cases of doubt between craniosynostosis and positional plagiocephaly, multiple numeric evaluations indicate regional deformities and severity of the asymmetry, which can help in the clinical decision of indicating or not the orthosis in positional deformities, determining treatment duration or evaluating surgical outcomes after correction. METHODS: A Matlab-based tool was developed for digital processing of photographs taken in 3 positions (anterior, superior and lateral). The software guides the user to select visible and reproducible landmarks in each photograph acquisition and calculates multiple indexes and metrics, generating a set of comprehensive plots to offer the user an overview of head and facial symmetry across the orthogonal views. For purposes of demonstration, we evaluated 2 patients (one control and one with non-sinostotic deformity). RESULTS: The results show a clear differentiation of the control and plagiocephalic patient metrics mainly in the superior view, showing potential for diagnosis of the condition, and also detected the clinical improvement during helmet treatment in the follow-up, 3 and 5 months after orthosis' use. CONCLUSION: We presented a proof-of-concept for a low cost, no radiation evaluation system for craniofacial asymmetries, that can be useful in a clinical context for diagnosis and follow-up of patients.

BACKGROUND: The incidence of positional plagiocephaly has increased significantly over the last two decades, which has caused a service delivery challenge for pediatric neurosurgeons. As a potential solution to the long waitlists for abnormal head shape, a plagiocephaly clinic was established at BC Children's Hospital (BCCH) in Vancouver, Canada. This clinic was supervised by an occupational therapist who had been trained by a neurosurgeon to independently assess and manage patients with a referring diagnosis of positional plagiocephaly. OBJECTIVES: To determine the efficiency of the BCCH Plagiocephaly Clinic in the management of positional plagiocephaly patients and to investigate the clinic's ability to appropriately identify and refer patients with craniosynostosis to pediatric neurosurgeons for further assessment. METHODS: A retrospective chart review was conducted to identify patients who were assessed and managed at the BCCH Plagiocephaly Clinic between 2008 and 2014. Data on patient demographics, head shape measurements, and treatment recommendations were collected, and the BC Children's neurosurgical database was cross-referenced to identify craniosynostosis cases missed by the Plagiocephaly Clinic. A descriptive analysis of the clinic's average wait times, severity of the patients' plagiocephaly, and recommended interventions was conducted. In addition, the sensitivity and specificity of the clinic's ability to appropriately refer craniosynostosis patients to pediatric neurosurgery were calculated. RESULTS: Of 1752 patients seen in the BC Children's Plagiocephaly Clinic between 2008 and 2014, 66% of patients received counseling about repositioning, 34% were referred for head banding, 19% were referred to physiotherapy for torticollis, and 1.4% were referred to the BC Children's Pediatric Neurosurgery Clinic for suspicion of craniosynostosis. The mean time from referral to first assessment by the Plagiocephaly Clinic was 41 days, and time from referral by the plagiocephaly clinic to diagnosis of craniosynostosis by a pediatric neurosurgeon was 8 days. Pediatric neurosurgeons requested imaging for 6 of the referred patients (25% ). The sensitivity and specificity of the plagiocephaly clinic for referral of craniosynostosis patients to the Pediatric Neurosurgery Clinic were 100 and 99%, respectively. CONCLUSION: The BC Children's Plagiocephaly Clinic is efficient and safe for the initial evaluation and treatment of patients with positional plagiocephaly. The clinic's model decreases wait times, appropriately manages patients with positional plagiocephaly, screens for craniosynostosis with high sensitivity and specificity, and takes pressure off outpatient neurosurgical clinics. This model for assessment of plagiocephaly could be considered in other medical centers.

PURPOSE: This study aimed to investigate the effect of age at helmet therapy onset on treatment efficacy in moderate-to-severe deformational plagiocephaly (DP) and combined DP and asymmetrical brachycephaly (AB) in infants. METHODS: Ninety-eight infants who were referred to our institution and who underwent helmet therapy between 2014 and 2018 were retrospectively reviewed. Patients with DP [cranial vault asymmetry index (CVAI) > 7% and DD > 10 mm] and AB [CVAI > 7% and cephalic ratio (CR) ≥ 94] were included. Pre- and post-treatment calvarial asymmetries (difference among DD, CVAI, and CR) were measured using 3D screening systems (SmartSoc and Omega Scanner 3D). Infants were classified according to age at treatment onset: group 1 (age, < 6 months) and group 2 (age, ≥ 6 months). RESULTS: CVAI was statistically different between treatment onset and end in subgroups. Moreover, the regression of CVAI between groups DP1 (- 7.5% ± 1.2%) versus DP2 (- 5.4% ± 1.5%; p = 0.001) and groups AB1 (- 6.6% ± 1.4%) versus AB2 (- 4.4 ± 2.5; p = 0.0013) was statistically significant. CVAI was < 3.5% and CR was ≤ 89 (assumed as normal cranial shape) after treatment in 48%, 40%, 32%, and 6% of infants in groups DP1, DP2, AB1, and AB2, respectively. CONCLUSION: These findings emphasize the efficacy of helmet therapy for DP and AB. Helmet is an appropriate treatment option particularly for infants with severe DP and AB, and early onset of helmet therapy before the age of 6 months is advised.
