Abstract
The Craniofacial Collaboration UK (CC-UK) protocol is a shared agreement across the 4 UK Highly Specialist Craniofacial Centres (HSCCs) to conduct robust neurodevelopmental and psychosocial clinical screening for children with craniosynostosis. This agreement allows for the analysis of outcomes of a homogenous sample of children with single suture craniosynostosis (SSC), a frequent limitation of the existing research. The current study is the latest analysis of CC-UK data on behavioral, cognitive, and psychosocial outcomes. The focus of this analysis is 7- and 10-year-olds with nonsyndromic sagittal synostosis (SS) who have undergone primary corrective surgery and completed routine clinical screening at 1 of the 4 HSCCs since the introduction of the CC-UK protocol. Due to changes in clinical pathways, only data from 3 HSCCs is included to preserve homogeneity. Results show that the majority of children with SS fall within the average range across behavioral and neurodevelopmental domains. A notable exception was a task involving perceptual reasoning and visuomotor skills (Block Design). Although this difference was small and the mean score remained within the average range, it suggests some increased risk of subtle difficulty with such skills for children with SS. Across other measures, there was no consistent evidence of any significantly increased risk of poorer outcomes, in line with findings of previous CC-UK papers. Understanding the psychological phenotype of SS is a key research priority for parents and clinicians, and the current study is another step toward achieving this goal.

Cognitive Outcomes of Children With Sagittal Craniosynostosis Treated With Either Endoscopic or Open Calvarial Vault Surgery. JAMA Netw Open 2024; 7:e248762. [PMID: 38683606 PMCID: PMC11059043 DOI: 10.1001/jamanetworkopen.2024.8762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 02/29/2024] [Indexed: 05/01/2024] Open
Abstract
Importance Several studies have reported a higher incidence of neurodevelopmental delays and cognitive deficits in patients with single-suture craniosynostosis; however, there are few studies examining the associations of repair type with cognitive outcomes. Objective To measure differences in neuropsychological outcomes between school-age children who were treated for sagittal craniosynostosis and unaffected controls and explore differences in cognitive function among children with sagittal craniosynostosis who were previously treated with either endoscopic strip craniectomy or open calvarial vault surgery. Design, Setting, and Participants This cohort study was performed between 2018 and 2022. Eligible participants included patients aged 5 to 17 years who had previously been seen as infants or toddlers (<3 years) at 1 of 3 surgical centers for craniosynostosis repair with either endoscopic surgery or open calvarial vault surgery. A separate cohort of unaffected controls were included for comparison. Data analysis was conducted from November 2023 to February 2024. Exposures Open calvarial vault surgery or endoscopic repair for single-suture craniosynostosis. Main Outcomes and Measures The primary outcome was the Differential Ability Scales-II (DAS-II) General Conceptual Ability (GCA) score, an index for overall intellectual ability. Secondary outcomes included DAS-II subscale scores (Verbal Ability, Nonverbal Reasoning, Spatial Ability, Working Memory, and Processing Speed), and Patient-Reported Outcomes Measurement Information System (PROMIS) cognitive function scores. Results A total of 81 patients with sagittal craniosynostosis (59 male [73%]; 22 female [27%]) and 141 controls (81 male [57%]; 60 female [43%]) were included. Of the 81 participants with sagittal craniosynostosis, 46 underwent endoscopic repair and 35 underwent open repair. Median (range) age at time of follow-up assessment was 7.7 (5.0-14.8) years for children with sagittal craniosynostosis and median age at assessment was 8.5 (7.7-10.5) years for controls. After controlling for age at assessment, sex, and socioeconomic status, there was no statistically significant or clinically meaningful difference in GCA scores between children who underwent endoscopic repair (adjusted mean score, 100; 95% CI, 96-104) and open repair (adjusted mean score, 103; 95% CI, 98-108) (P > .99). We found no significant difference in PROMIS scores between repair types (median [range] for endoscopic repair 54 [31-68] vs median [range] for open repair 50 [32-63]; P = .14). When comparing the treatment groups with the unaffected controls, differences in subscale scores for GCA and working memory were observed but were within normal range. Conclusions and Relevance In this cohort study, there were no statistically or clinically significant differences in cognitive outcomes among school-age children by and type of surgical procedure used to repair nonsyndromic sagittal craniosynostosis. These findings suggest primary care clinicians should be educated about different options for craniosynostosis surgery to ensure early referral of these patients so that all treatment options remain viable.

Abstract
Sagittal Craniosynostosis (SC) is a congenital craniofacial malformation, involving premature sagittal suture ossification; spring-assisted cranioplasty (SAC) - insertion of metallic distractors for skull reshaping - is an established method for treating SC. Surgical outcomes are predictable using numerical modelling, however published methods rely on computed tomography (CT) scans availability, which are not routinely performed. We investigated a simplified method, based on radiation-free 3D stereophotogrammetry scans.Eight SAC patients (age 5.1 ± 0.4 months) with preoperative CT and 3D stereophotogrammetry scans were included. Information on osteotomies, spring model and post-operative spring opening were recorded. For each patient, two preoperative models (PREOP) were created: i) CT model and ii) S model, created by processing patient specific 3D surface scans using population averaged skin and skull thickness and suture locations. Each model was imported into ANSYS Mechanical (Analysis System Inc., Canonsburg, PA) to simulate spring expansion. Spring expansion and cranial index (CI - skull width over length) at times equivalent to immediate postop (POSTOP) and follow up (FU) were extracted and compared with in-vivo measurements.Overall expansion patterns were very similar for the 2 models at both POSTOP and FU. Both models had comparable outcomes when predicting spring expansion. Spring induced CI increase was similar, with a difference of 1.2%±0.8% for POSTOP and 1.6%±0.6% for FU.This work shows that a simplified model created from the head surface shape yields acceptable results in terms of spring expansion prediction. Further modelling refinements will allow the use of this predictive tool during preoperative planning.

Abstract
The Craniofacial Collaboration UK (CC-UK) is a shared initiative with the aim of addressing key limitations in the existing literature and examining the development of homogenous samples of children with craniosynostosis. This article preliminarily describes developmental, behavioral, and cognitive outcomes for children with either metopic synostosis (MS) or sagittal synostosis (SS), who were unoperated and managed conservatively under the CC-UK protocol. A total of 112 patients were included, and assessments conducted at 3 and/or 7 years of age are presented. The majority of unoperated patients were assessed as having mild clinical severity. Findings are broadly consistent with previous work, indicating that the majority of unoperated patients perform within the average ranges across assessments. For unoperated MS patients, higher than expected rates of developmental concerns were seen at 3 years, particularly relating to gross and fine motor skills, and personal social skills. Slightly elevated rates of behavioral concerns relating to hyperactivity and prosocial behavior were also consistently shown. Few developmental issues were found for SS patients at 3 years. Some minor concerns with peer relationships and prosocial behavior at 3 years, and emotional problems at 7 years were shown, but these were inconsistent over time. Cognitive ability in both groups at 7 years seems to be close to average. Overall findings are positive, and future work should build on these findings by recruiting larger samples and examining longer-term outcomes in adolescence and adulthood, to better understand the developmental trajectory of patients with unoperated craniosynostosis.

Abstract
While the nervous system may be best known as the sensory communication center of an organism, recent research has revealed a myriad of multifaceted roles for both the CNS and PNS from early development to adult regeneration and remodeling. These systems work to orchestrate tissue pattern formation during embryonic development and continue shaping pattering through transitional periods such as metamorphosis and growth. During periods of injury or wounding, the nervous system has also been shown to influence remodeling and wound healing. The neuronal mechanisms responsible for these events are largely conserved across species, suggesting this evidence may be important in understanding and resolving many human defects and diseases. By unraveling these diverse roles, this paper highlights the necessity of broadening our perspective on the nervous system beyond its conventional functions. A comprehensive understanding of the complex interactions and contributions of the nervous system throughout development and adulthood has the potential to revolutionize therapeutic strategies and open new avenues for regenerative medicine and tissue engineering. This review highlights an important role for the nervous system during the patterning and maintenance of complex tissues and provides a potential avenue for advancing biomedical applications.

Abstract
Introduction: Children with single suture craniosynostosis (SSC) are at risk for neurocognitive problems. The reported magnitude of differences between children with SSC and their normative peers on standardized tests of academic and intellectual ability are small. Evaluation of real-world academic outcomes of these children and its impact on educational resources have not been conducted. Methods: A retrospective cohort study of academic outcomes of children with SSC was conducted using the data from Ontario's Education Quality and Accountability Office (EQAO) standardized provincial reading, writing and mathematics tests. The need for special education was identified by documentation of the child's need for an Identification, Placement, and Review Committee (IPRC). Results: Of 296 eligible children, 42 participated in the study. Half of the children had sagittal synostosis, while the remaining were 10 (24%) unicoronal, 9 (21%) metopic, and 2 (5%) lambdoid synostosis. Thirty-six (86%) underwent operative management. The EQAO scores of operated children with SSC met the provincial academic standards on the Grade 3 and 6 EQAO scores across the 3 academic subjects. Converted grade-matched EQAO scores decreased in reading and writing over time, while math improved. Of the 21 patients with special education data, one child required an IPRC in Grade 3, while an additional four (24%) required an IPRC in Grade 6. Conclusions: Operated children with SSC had average academic performance, however, their needs appeared to change over time. Future studies are needed to evaluate academic difficulties and special education needs as these children progress through grade school.

Abstract
OBJECTIVE Historically, there have been few quantitative methods for effectively evaluating outcomes after surgery for craniosynostosis. In this prospective study, we assessed a novel approach for detecting possible postsurgery brain injury in patients with craniosynostosis. METHODS We included consecutive patients operated on for sagittal (pi-plasty or craniotomy combined with springs) or metopic (frontal remodeling) synostosis at the Craniofacial Unit at Sahlgrenska University Hospital, Gothenburg, Sweden, from January 2019 to September 2020. Plasma concentrations of the brain-injury biomarkers neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and tau were measured immediately before induction of anesthesia, immediately before and after surgery, and on the first and the third postoperative days using single-molecule array assays. RESULTS Of the 74 patients included, 44 underwent craniotomy combined with springs for sagittal synostosis, 10 underwent pi-plasty for sagittal synostosis, and 20 underwent frontal remodeling for metopic synostosis. Compared with baseline, GFAP level showed a maximal significant increase at day 1 after frontal remodeling for metopic synostosis and pi-plasty (P = 0.0004 and P = 0.003, respectively). By contrast, craniotomy combined with springs for sagittal synostosis showed no increase in GFAP. For neurofilament light, we found a maximal significant increase at day 3 after surgery for all procedures, with significantly higher levels observed after frontal remodeling and pi-plasty compared with craniotomy combined with springs (P < 0.001). CONCLUSIONS These represent the first results showing significantly increased plasma levels of brain-injury biomarkers after surgery for craniosynostosis. Furthermore, we found that more extensive cranial vault procedures resulted in higher levels of these biomarkers relative to less extensive procedures.

Abstract
Background: Single suture craniosynostosis (SSC) is a disorder, affecting brain growth. Reviewing literature reveals controversialists of papers in this field. Methods: This prospective study was conducted from 2014 to 2016. All the individuals, aged 2 to 16 years, whose medical records files were complete, with SSC from 1999 to 2013 were included. All patients had undergone cranial vault remodeling at Mofid Hospital, Tehran, Iran. Wechsler questionnaires, WPPSI-III and WISC-IV, were completed for each child based on his/her age. Results: Seventy children were included, with the mean age of 6.7 (±2.9) years. Forty-six (65.7%) children were boys while 24 (34.3%) were girls. Mean FSIQ for all of children was 95.5 (±13.2). Mean verbal IQ, performance IQ, verbal comprehension, perceptual reasoning, processing speed, and working memory are 93.4 (±14.1), 96.1 (±13.3), 97.5 (±13.9), 102.2 (±12.5), 94.5 (±9.8), and 97.5 (±12.9), respectively. There was statistically significant difference between FSIQ of children with SSC and that of unaffected children (P-value<0.05). There was significant difference between verbal IQ of children with SSC and that of unaffected ones (P-value< 0.007). There was significant difference between in processing speed between affected children and unaffected children (P-value<0.012). Conclusion: Children, aged 2 to 6 years, with SSC had a significantly lower Verbal IQ, and children, aged 6 to 16 years, with SSC had a significantly lower processing speed than their healthy counterparts. Though FSIQ of children with SSC falls within normal range, it is a little lower than healthy peers.

Abstract
OBJECTIVE Craniosynostosis leads to craniofacial deformity and may result in raised intracranial pressure, neurocognitive deficits, and psychosocial issues if left untreated. The global epidemiology of craniosynostosis is unknown. We conducted a meta-analysis to estimate global birth prevalence. METHODS PubMed, Embase, and Scopus were searched. Articles were screened by title and abstract and then full text. Meta-analysis of birth prevalence was conducted. Birth prevalence figures were combined with metrics detailing the number of births in 2019 to estimate the number of children worldwide born with craniosynostosis annually. RESULTS Of 1378 resultant articles, 24 studies were included, including 20 providing data for craniosynostosis overall and 9 for nonsyndromic craniosynostosis. World Health Organization regions of included studies were 9 (37.5%) European Region, 8 (33.3%) Region of the Americas, 4 (16.7%) Western Pacific region, 2 (8.3%) African Region, and 1 (4.2%) Eastern Mediterranean Region. Lower middle-income countries represented only 4% of study manuscripts. The overall birth prevalence of craniosynostosis was 5.9 per 10,000 live births (20 studies; 95% confidence interval [CI]: 3.9, 8.4; I2 = 100%). The birth prevalence of nonsyndromic craniosynostosis was 5.2 per 10,000 live births (9 studies; 95% CI: 3.4, 7.3; I2 = 98%). The number of children born globally with craniosynostosis in 2019 was estimated to be 84,665 (95% CI: 55,965, 120,540), including 72,857 (95% CI: 47,637, 120,280) with nonsyndromic craniosynostosis. CONCLUSIONS Craniosynostosis is a common condition that affects the neurocognitive and craniofacial skeletal development of children worldwide. Initiatives to scale up capacity for craniosynostosis epidemiologic research and clinical care are warranted, particularly in low- and middle-income countries.

[PMID: 35213835 DOI: 10.3171/2022.1.peds21401] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Accepted: 01/13/2022] [Indexed: 01/09/2023]
Abstract
OBJECTIVE Outcomes research on unilateral coronal synostosis is mostly limited to the early postoperative period. This study examines facial asymmetry, desire for revision, and patient-reported outcomes at school age in children who received either endoscopic strip craniectomy with helmet therapy or fronto-orbital advancement (open repair). METHODS Patients with repaired unilateral coronal synostosis born between 2000 and 2017, with 3D photographs taken when they were between 3.5 and 8 years of age, were eligible for study inclusion. Three pairs of bilateral linear measurements and two angular measurements were taken. Parent- and physician-reported desire for revision and patient-reported outcomes (Patient-Reported Outcomes Measurement Information System cognitive function and Quality of Life in Neurological Disorders stigma scores) were collected from patient charts. RESULTS Thirty-five patients qualified, including 25 with open repair and 10 with endoscopic repair. The median patient ages at repair were 3 months and 8 months in the endoscopic and open groups, respectively. The average ages at final 3D photography were 5.8 years and 5.5 years in the endoscopic and open groups, respectively. Digital anthropometry revealed no significant differences in measures of facial asymmetry between the repair groups (p ≥ 0.211). Midface depth (tragion to subnasale) was significantly less symmetric at school age than other linear measures (F(2,102) = 9.14, p < 0.001). Forehead asymmetry was significantly associated with parent- and physician-reported desire for revision (p ≤ 0.006). No significant associations were found between physical asymmetry and patient-reported stigma or cognitive function (p > 0.046, Holm-Bonferroni correction). CONCLUSIONS Children who underwent open or endoscopic repair for unilateral coronal synostosis have comparable facial symmetry at school age, but midface depth remains highly asymmetrical in both groups. Forehead asymmetry at school age correlates with parent- and physician-reported desire for revision.

Abstract
ABSTRACT The Craniofacial Collaboration UK (CC-UK) has been established across the 4 highly specialized craniofacial centers in the UK since 2015. This joint collective aims to address the current limitations within developmental craniofacial research, using robust clinical data from a homogenous sample of children. This paper presents the third wave of findings from the CC-UK, with consideration to developmental and behavioral parent-report measures. Whilst previous data for sagittal synostosis have been presented, this article summarizes the analysis of these outcomes for children with metopic synostosis (MS) at 3 years who have undergone primary corrective surgery. Results highlight similar patterns to that of earlier CC-UK work, with the majority of children falling within 1 standard deviation of the population normative means across all measures. However, statistically significant difficulties were found between group means for children with MS on various developmental and behavioral domains. Prosocial skills and peer difficulties were reported as the greatest areas of behavioral concern for parents, with prosocial skills found to be below the level expected for their chronological age. In order to further understand the developmental trajectory of children with MS, longitudinal examination of individual diagnostic and specific age groups with single-suture craniosynostosis is crucial. The continuation of the CC-UK provides an opportunity to attain this goal.

Abstract
OBJECTIVE Endoscopic strip craniectomy (ESC) and spring-mediated cranioplasty (SMC) are two minimally invasive techniques for treating sagittal craniosynostosis in early infancy. Data comparing the perioperative outcomes of these two techniques are sparse. Here, the authors hypothesized that outcomes would be similar between patients undergoing SMC and those undergoing ESC and conducted a study using the multicenter Pediatric Craniofacial Surgery Perioperative Registry (PCSPR). METHODS The PCSPR was queried for infants under the age of 6 months who had undergone SMC or ESC for sagittal synostosis. SMC patients were propensity score matched 1:2 with ESC patients on age and weight. Primary outcomes were transfusion-free hospital course, intensive care unit (ICU) admission, ICU length of stay (LOS), and hospital length of stay (HLOS). The authors also obtained data points regarding spring removal. Comparisons of outcomes between matched groups were performed with multivariable regression models. RESULTS The query returned data from 676 infants who had undergone procedures from June 2012 through September 2019, comprising 580 ESC infants from 32 centers and 96 SMC infants from 5 centers. Ninety-six SMC patients were matched to 192 ESC patients. There was no difference in transfusion-free hospital course between the two groups (adjusted odds ratio [aOR] 0.78, 95% CI 0.45-1.35). SMC patients were more likely to be admitted to the ICU (aOR 7.50, 95% CI 3.75-14.99) and had longer ICU LOSs (incident rate ratio [IRR] 1.42, 95% CI 1.37-1.48) and HLOSs (IRR 1.28, 95% CI 1.17-1.39). CONCLUSIONS In this multicenter study of ESC and SMC, the authors found similar transfusion-free hospital courses; however, SMC infants had longer ICU LOSs and HLOSs. A trial comparing longer-term outcomes in SMC versus ESC would further define the roles of these two approaches in the management of sagittal craniosynostosis.

Evaluating Surgical Decision-making in Nonsyndromic Sagittal Craniosynostosis Using a Digital 3D Model. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3493. [PMID: 34036018 PMCID: PMC8140767 DOI: 10.1097/gox.0000000000003493] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 01/26/2021] [Indexed: 11/25/2022]
Abstract
Surgical correction of craniosynostosis addresses potentially elevated intracranial pressure and the cranial deformity. In nonsyndromic sagittal synostosis, approximately 15% of patients have elevated intracranial pressure. The decision to operate therefore likely reflects a combination of aesthetic goals, prevention of brain growth restriction over time, surgeon training and experience, and parental expectations. This study examines clinical factors that influence surgical decision-making in nonsyndromic sagittal synostosis. Methods An online survey sent to craniofacial and neurosurgeons presented 5 theoretical patients with varying severities of sagittal synostosis. For each cephalic index, 4 separate clinical scenarios were presented to assess influences of parental concern and developmental delay on the decision to operate. Results Fifty-six surveys were completed (response rate = 28%). Participants were predominantly from North America (57%), had over 10 years of experience (75%), and performed over 20 craniosynostosis procedures annually (50%). Thirty percent of respondents indicated they would operate regardless of head shape and without clinical and/or parental concern. Head shape was the greatest predictor of decision to operate (P < 0.001). Parental concern and developmental delay were independently associated with decision to operate (P < 0.001). Surgeons with more experience were also more likely to operate across all phenotypes (OR: 2.69, P < 0.004). Conclusions Surgeons responding to this survey were more strongly compelled to operate on children with nonsyndromic sagittal craniosynostosis when head shape was more severe. Additional factors, including parental concern and developmental delay, also influence the decision to operate, especially for moderate phenotypes. Geographic and subspecialty variations were not significant.

Abstract
Craniosynostosis is the premature fusion of 1 or more sutures that normally separate the bony plates of an infant's skull and occurs in about 1 in 2,000 to 2,500 live births. Primary or congenital craniosynostoses represent the majority of cases and consist of single-suture and multisuture synostoses. Multisuture synostoses are typically associated with distinct craniofacial syndromes, including Muenke syndrome, Apert syndrome, Crouzon syndrome, and Pfeiffer syndrome, and are thus categorized under syndromic craniosynostoses. Secondary causes of craniosynostoses include metabolic or hematologic disorders that affect bone metabolism and typically present much later than primary synostoses. The severity of the deformity and the presence of increased intracranial pressure dictate the need for early surgical intervention, prompting the importance of early recognition and timely referral. Infants with craniosynostosis are also at increased risk for neurodevelopmental impairment and thus require close follow-up and monitoring. The early recognition and referral of craniosynostosis is imperative for the optimization of management and minimization of potential neurologic impairments that may develop.

Abstract
OBJECTIVE Surgical correction for sagittal and metopic craniosynostosis (SCS and MCS) aims to alter the abnormal cranial shape to resemble that of the normal population. The achieved correction can be assessed by morphometric parameters. The purpose of the presented study was to compare craniometric parameters of control groups to those same parameters after endoscopic and conventional (open) correction. METHODS The authors identified 4 groups of children undergoing surgical treatment for either SCS or MCS, with either endoscopic (SCS, n = 17; MCS, n = 16) or conventional (SCS, n = 29; MCS, n = 18) correction. In addition, normal control groups of nonaffected children who were 6 (n = 30) and 24 (n = 18) months old were evaluated. For all groups, several craniometric indices calculated from 3D photographs were compared for quantitative analysis. For qualitative comparison, averages of all 3D photographs were generated for all groups and superimposed to visualize relative changes. RESULTS For children with SCS, the cephalic index and coronal circumference index significantly differed preoperatively from those of the 6-month normal controls. The respective postoperative values were similar to those of the 24-month normal controls after both endoscopic and conventional correction. Similarly, for children with MCS, indices for circumference and diagonal dimension that were significantly different preoperatively became nonsignificantly different from those of 24-month normal controls after both endoscopic and conventional correction. The qualitative evaluation of superimposed average 3D head shapes confirmed changes toward normal controls after both treatment modalities for SCS and MCS. However, in SCS, the volume gain, especially in the biparietal area, was more noticeable after endoscopic correction, while in MCS, relative volume gain of the bilateral forehead was more pronounced after conventional correction. The average 3D head shapes matched more homogeneously with the average of normal controls after endoscopic correction for SCS and after conventional correction for MCS. CONCLUSIONS This quantitative analysis confirms that the performed surgical techniques of endoscopic and conventional correction of SCS and MCS alter the head shape toward those of normal controls. However, in a qualitative evaluation, the average head shape after endoscopic technique for SCS and conventional correction for MCS appears to be closer to that of normal controls than after the alternative technique. This study reports on morphometric outcomes after craniosynostosis correction. Only an assessment of the whole multiplicity of outcome parameters based on multicenter data acquisition will allow conclusions of superiority of one surgical technique.

Abstract
BACKGROUND Single-suture craniosynostosis (SSC) can be associated with neurodevelopmental deficits. We examined the correlation between morphologic severity and incidence of speech-language or psychological concerns. METHODS In 62 patients (33 sagittal, 17 metopic, and 12 unicoronal), morphologic severity was determined via preoperative computed tomography (CT). Severity metrics for sagittal, metopic, and unicoronal synostosis were adjusted cephalic index (aCI), interfrontal angle (IFA), and anterior cranial fossa area ratio (ACFR), respectively. Speech-language and psychological concerns were assessed at age ≥4.5 years and defined as recommendation for therapy or monitoring. RESULTS Mean assessment age was 5.7 years; 32% had a speech-language concern and 44% had a psychological concern; 44% had neither. Sagittal: Mean aCI of those with a speech-language concern (0.62) and those without (0.62) were equivalent (P = .580), as were mean aCI of those with a psychological concern (0.62) and those without (0.62; P = .572). Metopic: Mean IFA with (117.9) and without (125.2) a speech-language concern were equivalent (P = .326), as were mean IFA with (120.2) and without (123.2) a psychological concern (P = .711). Unicoronal: Mean ACFR with (0.65) and without (0.69) a psychological concern (P = .423) were equivalent. However, mean ACFR with (0.74) and without (0.63) a speech-language concern were not (P = .022*). Bivariate rank correlation showed significant association between morphologic severity and speech-language score only for unicoronal synostosis (ρ = .722; P = .008*). CONCLUSION A significant portion of patients with SSC had speech-language or psychological concerns. We found no correlation between morphologic severity and incidence of speech-language or psychological concerns for patients with sagittal or metopic synostosis. Morphological severity did correlate with speech concerns in patients with unicoronal synostosis.

Abstract
INTRODUCTION Trigonocephaly (TC), the tapering of the metopic suture toward the anterior, lateral inadequacy of supraorbital bar, hypoplasia of the ethmoid bone, and hypotelorism due to orbital medialization leads to a triangular shape in the head together with frontotemporal stenosis and widening of the biparietal diameter. Arachnoid cysts (ACs) are benign cysts, which are formed by cerebrospinal-fluid entrapment into the arachnoid membrane due to duplication or separation of the arachnoid membrane layers. ACs are typically located in the middle cranial fossa and Sylvian fissure region. They are mostly detected incidentally through neuroimaging. The coexistence of TC and AC is considerably rare; hence, its actual incidence is unknown. To our knowledge, the coexistence of nonsyndromic TC and AC has been revealed in only 2 publications in the literature. In this case study, 2 patients, one of whom were with unilateral and the other with bilateral temporally localized ACs, sizes of which increased following the reconstructive surgeries, and who underwent reconstructive surgery for TC, were presented. CASE REPORT Both of the 2 patients that we have presented in our study are 7 months old and male. Fronto-orbital advancement and calvarial remodeling operations were performed on both. ACs of the patients were not intervened. However, in the post-op follow-ups, the left temporal cyst of the 1st case and the right cyst of the 2nd case grew radiologically, and the left cyst became very small. DISCUSSION/CONCLUSION TC must be treated surgically. ACs may show changes in size secondary to the increase in intracranial volume following reconstructive surgery for TC. However, if it does not give rise to any complaints, it can be followed-up clinically and radiologically. Patients should be followed-up for many years, given that neurodevelopmental and behavioral problems may occur later in both pathologies.

Abstract
BACKGROUND During development, excessive osteogenic differentiation of mesenchymal progenitor cells (MPC) within the cranial sutures can lead to premature suture fusion or craniosynostosis, leading to craniofacial and cognitive issues. Saethre-Chotzen syndrome (SCS) is a common form of craniosynostosis, caused by TWIST-1 gene mutations. Currently, the only treatment option for craniosynostosis involves multiple invasive cranial surgeries, which can lead to serious complications. METHODS The present study utilized Twist-1 haploinsufficient (Twist-1del/+) mice as SCS mouse model to investigate the inhibition of Kdm6a and Kdm6b activity using the pharmacological inhibitor, GSK-J4, on calvarial cell osteogenic potential. RESULTS This study showed that the histone methyltransferase EZH2, an osteogenesis inhibitor, is downregulated in calvarial cells derived from Twist-1del/+ mice, whereas the counter histone demethylases, Kdm6a and Kdm6b, known promoters of osteogenesis, were upregulated. In vitro studies confirmed that siRNA-mediated inhibition of Kdm6a and Kdm6b expression suppressed osteogenic differentiation of Twist-1del/+ calvarial cells. Moreover, pharmacological targeting of Kdm6a and Kdm6b activity, with the inhibitor, GSK-J4, caused a dose-dependent suppression of osteogenic differentiation by Twist-1del/+ calvarial cells in vitro and reduced mineralized bone formation in Twist-1del/+ calvarial explant cultures. Chromatin immunoprecipitation and Western blot analyses found that GSK-J4 treatment elevated the levels of the Kdm6a and Kdm6b epigenetic target, the repressive mark of tri-methylated lysine 27 on histone 3, on osteogenic genes leading to repression of Runx2 and Alkaline Phosphatase expression. Pre-clinical in vivo studies showed that local administration of GSK-J4 to the calvaria of Twist-1del/+ mice prevented premature suture fusion and kept the sutures open up to postnatal day 20. CONCLUSION The inhibition of Kdm6a and Kdm6b activity by GSK-J4 could be used as a potential non-invasive therapeutic strategy for preventing craniosynostosis in children with SCS. Pharmacological targeting of Kdm6a/b activity can alleviate craniosynostosis in Saethre-Chotzen syndrome. Aberrant osteogenesis by Twist-1 mutant cranial suture mesenchymal progenitor cells occurs via deregulation of epigenetic modifiers Ezh2 and Kdm6a/Kdm6b. Suppression of Kdm6a- and Kdm6b-mediated osteogenesis with GSK-J4 inhibitor can prevent prefusion of cranial sutures.

Abstract
OBJECTIVES Craniosynostosis is typically diagnosed and surgically corrected within the first year of life. The diagnosis and surgical correction of the condition can be a very stressful experience for families. Despite this, there is little research exploring the impact that craniosynostosis has on families, especially in the period immediately following diagnosis and correction. In this study, the authors aimed to qualitatively examine the psychosocial experience of families with a child diagnosed with craniosynostosis. DESIGN Qualitative study. SETTING Tertiary care paediatric health centre. PARTICIPANTS Mothers of children newly diagnosed with single-suture, non-syndromic craniosynostosis. INTERVENTION Semistructured interviews regarding parental experience with the initial diagnosis, their decision on corrective surgery for their child, the operative experience, the impact of craniosynostosis on the family and the challenges they encountered throughout their journey. PRIMARY AND SECONDARY OUTCOME MEASURES Thematic analysis, a type of qualitative analysis that provides an in-depth account of participant's experiences, was used to analyse the interview data. RESULTS Over a 4-year period, 12 families meeting eligibility criteria completed the study. Three main themes (six subthemes) emerged from the preoperative interviews: frustration with diagnostic delays (parental intuition and advocacy, hope for improved awareness), understanding what to expect (healthcare supports, interest in connecting with other families) and justifying the need for corrective surgery (influence of the surgeon, struggle with cosmetic indications). Two main themes (four subthemes) were drawn from the postoperative interviews: overcoming fear (the role of healthcare professionals, transition home) and relief (reduction in parental anxiety, cosmetic improvements). CONCLUSIONS Overall, the diagnosis of craniosynostosis has a profound impact on families, leading them to face many struggles throughout their journey. A better understanding of these experiences will help to inform future practice, with a hope to improve this experience for other families moving forward.

Abstract
Pediatric care providers, pediatricians, pediatric subspecialty physicians, and other health care providers should be able to recognize children with abnormal head shapes that occur as a result of both synostotic and deformational processes. The purpose of this clinical report is to review the characteristic head shape changes, as well as secondary craniofacial characteristics, that occur in the setting of the various primary craniosynostoses and deformations. As an introduction, the physiology and genetics of skull growth as well as the pathophysiology underlying craniosynostosis are reviewed. This is followed by a description of each type of primary craniosynostosis (metopic, unicoronal, bicoronal, sagittal, lambdoid, and frontosphenoidal) and their resultant head shape changes, with an emphasis on differentiating conditions that require surgical correction from those (bathrocephaly, deformational plagiocephaly/brachycephaly, and neonatal intensive care unit-associated skill deformation, known as NICUcephaly) that do not. The report ends with a brief discussion of microcephaly as it relates to craniosynostosis as well as fontanelle closure. The intent is to improve pediatric care providers' recognition and timely referral for craniosynostosis and their differentiation of synostotic from deformational and other nonoperative head shape changes.

Abstract
OBJECTIVE The aim of this study was to evaluate the dental age, agenesis, and morphology of children with surgically operated single-suture craniosynostoses from orthopantomographs. DESIGN A single-centered cross-sectional observational archival study. PATIENTS A sample of 196 Finnish patients with single-suture craniosynostosis without additional birth defects or syndromes (excluding Muenke syndrome) was included in this study. MAIN OUTCOME MEASURES Dental age was assessed using the method developed by Demirjian et al. and modified by Nyström et al. for the Finnish population. Methods described by Tulensalo et al. and Oehlers et al. were used to study taurodontism and dens invaginatus, respectively. RESULTS The study sample of 149 patients was divided into 3 groups: patients with sagittal synostosis (n = 103), coronal synostosis (n = 25), and metopic synostosis (n = 21). Orthopantomographs taken on average at ages 8.20 to 8.33 were used. The dental ages in different groups were on average 0.37, 0.60, and 0.66 years ahead of normative values, for sagittal, coronal, and metopic groups, respectively. Tooth agenesis, taurodontism, and invaginated teeth were found in all groups with invaginations having a high prevalence. Peg-shaped upper lateral incisors and one geminated lower lateral incisor were also found. CONCLUSIONS These descriptive data may help improve dental care in patients with single-suture craniosynostosis.

Single-suture craniosynostosis: is there a correlation between preoperative ophthalmological, neuroradiological, and neurocognitive findings? Childs Nerv Syst 2020; 36:1481-1488. [PMID: 32006097 DOI: 10.1007/s00381-020-04521-w] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Accepted: 01/25/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND In spite of literature data stating that children with single-suture craniosynostosis have an increased risk for neuropsychological deficits, no data are present clarifying the potential risk factors. METHODS All children with non-syndromic single-suture craniosynostosis operated on from January 2014 to January 2017 were enrolled. A comprehensive neurocognitive and neuro-ophthalmological evaluation was performed before surgery and 6 months after surgery. A further neurocognitive evaluation was performed 12 months after surgery. All children had a preoperative CT/MR study. RESULTS One hundred forty-two patients were enrolled; 87 are affected by sagittal craniosynostosis, 38 by trigonocephaly, and 17 by plagiocephaly. A global neurocognitive impairment was documented in 22/87 children with scaphocephaly, 5/38 children with trigonocephaly, and 6/17 children with anterior plagiocephaly. There was a significant relationship between results of the ophthalmological evaluation, global IQ, and CT findings at diagnosis (r = 0.296, p < 0.001; r =0.187, p 0.05). Though a significant recovery was documented after surgery, a persistence of eye coordination deficits was present at 6 months in 1 out of 3 children with abnormal preoperative exams. A significant correlation was found between pathological CT findings and persistence of below average neuro-ophthalmological and neurocognitive findings 6 months after surgery, as well as between CT findings and neurocognitive scores at the 1 year follow-up (r = 0.411; p < 0.01). CONCLUSION The presence of neuroradiological abnormalities appears to be related to both ophthalmological and neurocognitive deficits at diagnosis. This relationship is maintained in spite of the surgical treatment in children who show the persistence of ophthalmological and neurocognitive deficits during the follow-up.

Intracranial pressure, brain morphology and cognitive outcome in children with sagittal craniosynostosis. Childs Nerv Syst 2020; 36:689-695.

Abstract
BACKGROUND Patients with sagittal craniosynostosis are at increased risk of developing raised intracranial pressure (ICP) and neurocognitive deficiencies such as reduced attention, planning, speech, behavioural and learning disabilities. AIM To determine if the existing literature supports a correlation between elevated ICP and negative cognitive outcome in patients with sagittal craniosynostosis. Secondly, to investigate if the risk of developing neurocognitive deficiencies can be explained by changes in brain morphology in this patient category. METHODS Systematic literature review in PubMed. RESULTS A total of 190 publications were reviewed to determine a possible correlation between raised ICP and cognitive outcome, of which four were included in the study. No significant association was found. Forty-four publications on brain morphology in sagittal craniosynostosis were identified, of which 11 were included in the review. Clear evidence of morphologic changes in multiple areas of the brains of sagittal craniosynostosis patients was found in the literature. CONCLUSION The existing literature does not support an association between increased ICP and negative global cognitive outcome measures in patients with sagittal craniosynostosis. Brain morphology is altered in areas related to neurocognition and language in the same patient group. These changes might play a role in the development of neurocognitive deficiencies, though no definitive link is yet established, and further investigation is warranted.

Abstract
PURPOSE Chiari 1 malformation (CM1) is a well-known association with complex craniosynostosis (CC), while it has been rarely reported in association with monosynostosis. The aim of the present study is to investigate on the association between CM1 and untreated sagittal synostosis (USS). METHOD The study included 48 cases of sagittal synostosis (SS), untreated for misdiagnosis and associated with CM1. The children were firstly diagnosed for CM1 by MRI (mean age 9) than for SS (mean age 10.5) by three-dimensional computerized tomography (3D-CT), which documented the absence of the sagittal suture, in the presence of residual indentation of all the other sutures. Syndromic cases were diagnosed by clinical evaluation and molecular studies. RESULTS Of the 48 children harboring CM1 plus USS, 21 were asymptomatic for CM1 and are still on follow-up, while 27 children were operated for syringomyelia and scoliosis and/or occurrence of symptoms, three of them had an acute presentation (two papilledema and one sleep apneas) and 11 children had a documented increase of preoperative ICP. Craniovertebral decompression (CVD) was the first-line surgery in 24 children, 16 with duroplasty and five without and eight had also cerebellar (CBL) tonsil coagulation. A cranial vault remodelling was firstly performed in three children. Fifteen percent of children submitted to CVD needed a revision for cerebrospinal fluid (CSF) collection, while two needed both the supra- and infratentorial decompressive procedure and another two needed a treatment for the associated hydrocephalus. CONCLUSIONS The present study identified an USS in 27 (15.5%) of 174 CM1 children operated for a symptomatic CM1. We suggest to define this association CM1 plus USS, a new subtype of complex CM1. For the high percentage of complications and multiple procedures needed to solve the CM1, we advise to identify by 3D-CT scan these children before performing CVD. Our finding suggests also that, if left untreated, SS may lead to the delayed occurrence of a challenging subset of CM1.

Abstract
The Craniofacial Collaboration United Kingdom (CC-UK) was established across the 4 Highly Specialized Craniofacial Centres (HSCCs) in the UK in 2015. This is the first wave of data to be analyzed, looking at 3-year-old children with sagittal synostosis who have had primary corrective surgery. This is a comprehensive, homogenous dataset, looking at parental measures of development and behavior. The results indicate that the majority of children are rated by their parents as falling within one standard deviation of the mean for both developmental and behavioral measures. However, there was a trend across the age groups within the sample which, although not statistically significant, indicates that more developmental difficulties may become apparent as children get older. Behavior was rated as more problematic, and the areas of greatest parental concern were Conduct (challenging or confrontational behavior) and Hyperactivity domains, where 24% of children were rated as within the clinically significant range. Although the majority of children were rated as falling within the average range, the difference in the mean between the sagittal and the normative group was significant in 5 of the 6 behavioral domains. Further research is required to examine whether these findings are stable over time and to look at the mechanism which might be driving these changes. It is anticipated that future CC-UK analysis will elucidate this more clearly.

Abstract
BACKGROUND Some patients with isolated sagittal craniosynostosis have demonstrated mild neurodevelopmental delays. This study examined potential preoperative risk factors for developmental delay. METHODS Patients completed preoperative Bayley Scales of Infant and Toddler Development, Third Edition, and medical records were reviewed. Multivariate analyses of covariance and correlations were calculated. RESULTS Participants (n = 77) were predominantly male (77.9 percent) and were aged 2 to 12 months (mean, 5.1 ± 2.3 months). Patients were classified with no delays [n = 63 (82 percent)] or delays [n = 14 (18 percent)] in one or more developmental area(s). There were no group sociodemographic differences. Prenatally, patients with delays versus no delays had lower mean gestational age in weeks (36.9 ± 2.8 weeks versus 39.1 ± 1.7 weeks; p = 0.001) with higher rates of gestational diabetes (36 percent versus 5 percent; p = 0.006) and premature rupture of membranes (14 percent versus 2 percent; p = 0.026). At birth, patients with delays had lower mean birth weight (2982 ± 714 g versus 3374 ± 544 g; p = 0.053), higher rates of respiratory distress (29 percent versus 5 percent; p = 0.005), additional medical diagnoses (57 percent versus 13 percent; p = 0.001), and longer mean neonatal intensive care unit stays (1.4 ± 1.8 weeks versus 0.2 ± 0.9 week; p = 0.002). Variables differing by group had moderate correlations. CONCLUSIONS Patients with nonsyndromic sagittal craniosynostosis that had delays in development had lower gestational age and birth weight, with more prenatal and birth complications. These factors can help identify patients who might be at risk for delay and need close monitoring. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
OBJECTIVE There are currently no guidelines for the optimum age for surgical treatment of craniosynostosis. This systematic review summarizes and assesses evidence on whether there is an optimal age for surgery in terms of neurodevelopmental outcomes. METHODS The databases MEDLINE, PsycINFO, CINAHL, Embase + Embase Classic, and Web of Science were searched between October and November 2016 and searches were repeated in July 2017. According to PICO (participants, intervention, comparison, outcome) criteria, studies were included that focused on: children diagnosed with nonsyndromic craniosynostosis, aged ≤ 5 years at time of surgery; corrective surgery for nonsyndromic craniosynostosis; comparison of age-at-surgery groups; and tests of cognitive and neurodevelopmental postoperative outcomes. Studies that did not compare age-at-surgery groups (e.g., those employing a correlational design alone) were excluded. Data were double-extracted by 2 authors using a modified version of the Cochrane data extraction form. RESULTS Ten studies met the specified criteria; 5 found a beneficial effect of earlier surgery, and 5 did not. No study found a beneficial effect of later surgery. No study collected data on length of anesthetic exposure and only 1 study collected data on sociodemographic factors. CONCLUSIONS It was difficult to draw firm conclusions from the results due to multiple confounding factors. There is some inconclusive evidence that earlier surgery is beneficial for patients with sagittal synostosis. The picture is even more mixed for other subtypes. There is no evidence that later surgery is beneficial. The authors recommend that future research use agreed-upon parameters for: age-at-surgery cut-offs, follow-up times, and outcome measures.

Abstract
OBJECTIVE The aim of this study was to ascertain whether age at surgery has an impact on later neurodevelopmental outcomes for children with sagittal synostosis (SS). METHODS The developmental outcome data from patients who had surgery for SS and who attended their routine preoperative, 6-7 months postoperative, and 5-year-old developmental assessments (yielding general quotients [GQs]) (n = 50), 10-year-old IQ assessment (n = 54), and 15-year-old IQ assessment (n = 23) were examined, comparing whether they had surgery at < 7 months, 7 to < 12 months, or ≥ 12 months). RESULTS There was no significant effect for age at surgery for GQ at 5 years of age, but there was a significant effect (p = 0.0001) for those undergoing surgery at < 7 months in terms of preoperative gross locomotor deficit that resolved by 6-7 months postoperatively (increase of 22.1 points), and had further improved by 5 years of age (total increase of 29.4 points). This effect was lessened when surgery was performed later (total increase of 7.3 points when surgery was performed at ≥ 12 months). At 10 years of age, 1-way ANOVA showed a significant difference in Full Scale IQ (FSIQ) score (p = 0.013), with the highest mean FSIQ being obtained when surgery was performed at < 7 months of age (score 107.0), followed by surgery at 7 to < 12 months (score 94.4), and the lowest when surgery was performed at ≥ 12 months (score 93.6). One-way ANOVA for the Performance IQ (PIQ) was very similar (p = 0.012), with PIQ scores of 101.4, 91.4, and 87.3, respectively. One-way ANOVA for Verbal IQ (VIQ) was again significant (p = 0.05), with VIQ scores of 111.3, 98.9, and 100.4, respectively. At 15 years, 1-way ANOVA showed a significant difference in PIQ (p = 0.006), with the highest mean PIQ being obtained when surgery was performed at < 7 months (score 104.8), followed by surgery at 7 to < 12 months (score 90.0), and the lowest when surgery was at performed at ≥ 12 months of age (score 85.3). There were no significant results for FSIQ and VIQ, although there was a similar trend for better outcomes with early surgery. CONCLUSIONS The findings of this study add to the literature that suggests that early surgery for SS may result in improved neurodevelopmental outcomes, with surgery optimally undertaken when patients are < 7 months of age, and with those undergoing surgery at ≥ 12 months performing the least well. These results also have potential implications for ensuring early diagnosis and referral and for the type of surgery offered. Further research is needed to control for confounding factors and to identify the mechanism by which late surgery may be associated with poorer neurodevelopmental outcomes.

Abstract
Objective: To characterize differences in the clinical presentation and treatment outcomes of laryngomalacia in patients with and without craniosynostosis. Methods: A retrospective cohort study was performed comparing all patients with concomitant laryngomalacia and craniosynostosis seen at a tertiary care children’s hospital between 2000 and 2016 with a control group of patients with isolated laryngomalacia. Thirty-two patients with craniosynostosis (59% male) and 68 control patients (56% male) were included. There were no significant differences in age of diagnosis or incidence of prematurity. Symptom presentation, disease severity, swallowing function, comorbidities, treatment modalities, and outcomes were examined using logistic regression. Results: Patients with craniosynostosis had increased odds of presenting with stertor (odds ratio [OR] = 3.41, P = .022), increased work of breathing (OR = 18.8, P = .007), obstructive sleep apnea (OR = 8.48, P = .003), dysphagia (OR = 3.40, P = .008), and aspiration (OR = 40.2, P < .001) and decreased odds of presenting with stridor (OR = 0.0804, P < .001) compared with controls. Patients with craniosynostosis had increased odds of severe laryngomalacia (OR = 5.00, P = .031) and other airway anomalies such as tracheomalacia (OR = 5.73, P = .004), bronchomalacia (OR = 15.5, P = .013), and subglottic stenosis (OR = 2.75, P = .028). Treatment of patients with craniosynostosis was more likely to include tracheostomy (OR = 24.8, P < .001) and gastrostomy tube (OR = 88.4, P < .001). There were no significant differences in rates of supraglottoplasty. Conclusion: Clinical presentations, comorbidities, and treatments of laryngomalacia are significantly different in the context of craniosynostosis.

Abstract
Background: Recognition of the challenges inherent in psychology research related to cleft lip and/or palate (CL/P) and other craniofacial anomalies (CFAs) is far from novel; yet these challenges continue to limit progress within the field. The aim of the present article was to illustrate these challenges by utilizing data extracted from 2 recent literature reviews pertaining to psychological adjustment within CL/P and CFA research. Design: Data relating to 148 CL/P and 41 CFA studies were extracted, summarized, and compared, using percentages, figures, and χ2 calculations. Results: Comparable patterns were observed in both populations in relation to small sample sizes, wide age ranges, a reliance on data collection from single sites, and limited global coverage. Similarly, only one-third of all studies had used a comparison group, 42% of studies did not include the patient perspective, and fewer than 10% of studies had collected data longitudinally. Qualitative research was lacking across both populations, but particularly in relation to CFA. A higher proportion of CFA studies utilized validated measures and were less likely to exclude patients with additional anomalies. CFA studies most frequently focused on behavior and overall quality of life, while CL/P studies tended to investigate emotional well-being and social experiences. Conclusions: Findings illustrate the variability in research approaches, sampling, measurement, and analysis across both populations. There is a pressing need to address key methodological issues within craniofacial research and to examine the possible similarities and condition-specific differences between CL/P and other congenital craniofacial anomalies.

Abstract
Objective: To date, research investigating the psychological impact of craniofacial conditions has produced variability across outcomes. The aims of this article were to summarize the challenges that may contribute to this variability, and to offer alternative perspectives and approaches to guide future research and practice. Design: A comprehensive evaluation of papers exploring adjustment to congenital craniofacial conditions was conducted. Methodological approaches and underlying conceptual issues were identified and summarized. Results: The conceptual limitations identified include inherent challenges pertaining to the multifactorial and fluctuating nature of adjustment, a lack of consensus regarding the primary constituents of a positive outcome, scant use of appropriate models and theories, and a predominant focus on “deficits” over “strengths.” The methodological shortcomings identified include a lack of representative samples, biomedical inclusion/exclusion criteria, inconsistency in measurement, a relative absence of the patient perspective, variability in approaches to data analysis and interpretation, and the failure to draw on knowledge from other disciplines and related fields of health research. Findings are believed to be relevant to all disciplines involved in craniofacial research and practice. Conclusions: Existing literature remains markedly affected by a range of conceptual and methodological challenges, despite these challenges being identified 25 years ago. The present article proposes that a shift in the way we conceptualize and study craniofacial conditions is needed, in order to construct a comprehensive understanding of adjustment to craniofacial conditions, and to address the key unanswered questions important to all stakeholders.

Abstract
Cranial dysmorphology observed in patients with metopic craniosynostosis varies along a spectrum of severity including varying degrees of metopic ridging, bitemporal narrowing, and trigonocephaly. Management has been based upon the subjective clinical impression of presence and severity of trigonocephaly. Severity of cranial dysmorphology does not predict the occurrence or severity of associated abnormal neurodevelopment, as children with mild-to-moderate trigonocephaly may also experience developmental delays. The authors sought to determine the relationship between mild-to-moderate trigonocephaly and anterior cranial volume using a noninvasive laser shape digitizer (STARscanner) in patients with abnormal head shape.An IRB-approved retrospective review of a prospectively maintained database and medical records was performed. Two hundred three patients less than 1 year of age with abnormal head shape were categorized as having a metopic ridge with mild-to-moderate trigonocephaly, metopic ridge without trigonocephaly, or no ridge. Measurements of cranial volume, circumference, and symmetry were calculated by the STARscanner, which quantifies three-dimensional shape of the cranial surface. Measures were analyzed using a series of analyses of variance and post-hoc Tukey honest significant difference.The authors results showed ACV was significantly reduced in patients with mild-to-moderate trigonocephaly compared with those without metopic ridge (P = 0.009), and trended toward significance compared with those with a ridge but without trigonocephaly (P = 0.072). The ratio of anterior-to-posterior cranial volume was significantly reduced in those with mild-to-moderate trigonocephaly compared with those without metopic ridge (P = 0.036).In conclusion, patients with milder anterior cranial deformities demonstrated an association between a metopic ridge with mild-to-moderate trigonocephaly and reduced anterior cranial volume.

Abstract
OBJECTIVE Sagittal craniosynostosis results in a characteristic scaphocephalic head shape that is typically corrected surgically during a child's 1st year of life. The authors' objective was to determine the potential impact of being born with sagittal craniosynostosis by using validated health state utility assessment measures. METHODS An online utility assessment was designed to generate health utility scores for scaphocephaly, monocular blindness, and binocular blindness using standardized utility assessment tools, namely the visual analog scale (VAS) and the standard gamble (SG) and time trade-off (TTO) tests. Utility scores were compared between health states using the Wilcoxon and Kruskal-Wallis tests. Univariate regression was performed using age, sex, income, and education as independent predictors of utility scores. RESULTS Over a 2-month enrollment period, 122 participants completed the online survey. One hundred eighteen participants were eligible for analysis. Participants rated scaphocephaly due to sagittal craniosynostosis with significantly higher (p < 0.001) median utility scores (VAS 0.85, IQR 0.76-0.95; SG 0.92, IQR 0.84-0.98; TTO 0.91, IQR 0.84-0.95) than both monocular blindness (VAS 0.60, IQR 0.50-0.70; SG 0.84, IQR 0.68-0.94; TTO 0.84, IQR 0.67-0.91) and binocular blindness (VAS 0.25, IQR 0.20-0.40; SG 0.51, IQR 0.18-0.79; TTO 0.55, IQR 0.36-0.76). No differences were noted in utility scores based on participant age, sex, income, or education. CONCLUSIONS Using objective health state utility scores, authors of the current study demonstrated that the preoperatively perceived burden of scaphocephaly in a child's 1st year of life is less than that of monocular blindness. These relatively high utility scores for scaphocephaly suggest that the burden of disease as perceived by the general population is low and should inform surgeons' discussions when offering morbid corrective surgery, particularly when driven by aesthetic concerns.

Risk Factors for Delayed Referral to a Craniofacial Specialist for Treatment of Craniosynostosis. J Pediatr 2017; 186:165-171.e2. [PMID: 28456388 DOI: 10.1016/j.jpeds.2017.03.048] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2016] [Revised: 02/15/2017] [Accepted: 03/20/2017] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To assess the impact of age at referral on treatment options in craniosynostosis and to identify risk factors for referral delays in this population. STUDY DESIGN A retrospective cohort study was performed on patients with an abnormal head shape diagnosis treated at a single academic medical center between January 1, 2004 and January 1, 2014. Newly diagnosed patients with craniosynostosis were identified and referral patterns were examined. A multivariate logistic regression model was used to identify risk factors associated with the range of ages at initial referral. RESULTS A total of 477 patients were evaluated at our institution, 197 of whom were subsequently diagnosed with craniosynostosis. The median age at initial appointment was 5.6 months (mean 8.2 months). Only 28% of children were referred within 3 months of birth. Patients referred within 3 months of birth were less likely to have had preappointment imaging than those patients referred slightly later (OR 2.53, CI 1.07-5.98, P = .035). Several variables were associated with referral after 12 months of age including multiple suture involvement (OR 4.21, CI 1.06-16.68, P = .041), minority race (OR 4.96, CI 1.91-12.9, P ≤ .0001), and referral by a nonpediatrician (OR 6.9, CI 1.73-27.49, P = .006). CONCLUSIONS Obtaining imaging before referral to a specialist for abnormal head shape was associated with a delay in evaluation and potentially increases radiation exposure and limits treatment options in patients with craniosynostosis. In addition, children from minority groups, children referred from someone other than a pediatrician's office, and those with multiple suture craniosynostosis are at increased risk of delayed referral. Further studies into the cause of these delays are warranted.

Abstract
Children with single-suture craniosynostosis (SSC) have higher rates of learning disabilities and related neurocognitive problems than unaffected peers. Executive function (EF) and attention are thought to be areas of particular vulnerability, though studies to date have been limited by small sample sizes and a lack of control groups. We evaluated 179 school-aged children with SSC (cases) and 183 unaffected controls at an average age of 7 years using clinician-administered and parent and teacher report measures of EF and attention. Among children with SSC, we examined differences as a function of suture location (sagittal, metopic, unicoronal, or lambdoid) and age of corrective surgery. We used linear regression analyses, adjusted for potential confounders, to compare the two groups on all outcome measures. Cases scored lower than controls on most measures, though the magnitude of these differences was small and most were statistically insignificant. The largest relative deficit was on a measure of inhibitory control. Results changed little in sensitivity analyses adjusting for potential attrition bias and for the effects of developmental and academic interventions. Among cases, there were few differences in relation to the location of suture fusion or timing of surgery. Overall, we found limited evidence of broad deficits in EF or attention in children with SSC relative to unaffected controls. Neurocognitive development for children with SSC appears to be variable, across affected children and outcomes assessed. Further research is needed to understand the potential sources of this variability.

Abstract
OBJECTIVE A congenital craniofacial anomaly (CFA) is expected to impact upon several domains of psychological, emotional and social functioning, yet no recent reviews have comprehensively summarised the available literature. Further, existing reviews tend to draw upon literature in the field of cleft lip and palate, and do not give substantive attention to other types of CFAs. DESIGN A review of 41 papers published between January 2000 and March 2016 pertaining to psychological adjustment to CFAs. MAIN OUTCOME MEASURES Findings are presented according to key psychological domains: General Psychological Well-being, Quality of Life, Behaviour, Emotional Well-being, Social Experiences, Appearance, and Treatment-Related Experiences. RESULTS Current literature offers a contradictory picture of adjustment to CFAs. Psychological adjustment appeared to be comparable to norms and reference groups in approximately half of the papers related to non-syndromic CFAs, while more variation was found across domains among samples with syndromic CFAs. Associations were found between adjustment, physical health and cognitive function in several papers. The review identified a number of gaps in the literature, such as the inclusion of a wide range of diagnoses within research samples. CONCLUSIONS This review demonstrates the complexity of findings, both within and across domains, and highlights a number of methodological challenges.

Abstract
INTRODUCTION The relationship between nonsyndromic craniosynostosis and neurodevelopment remains controversial. Beyond standardized testing, little data exist about parental perceptions of their child's development. METHODS Parents of children who underwent cranial vault remodeling for nonsyndromic craniosynostosis from 2011 to 2015 were asked to complete an anonymous survey. RESULTS Twenty-two parents (31%) completed the survey. Patients included 52.4% males and 47.6% females with a mean age at surgery of 9.2 months and mean follow-up time of 19.8 months. Craniosynostosis types were primarily metopic (45%) and coronal (35%).The mean score for overall satisfaction with head shape with a maximum score of 10 was 9.2 (range 5-10). When answering whether their child is different for the better other than appearance with a 5 rating as "strongly agree," the mean score was 3.8 (range 1-5). When asked whether their child's motor, speech and behavior, or attention were different following surgery, the majority responded "No" (74%, 83%, and 67%, respectively).All parents would have their child undergo surgery again or recommend surgery to another family. There were no statistically significant differences when stratifying by age at surgery or length of follow-up. When stratifying by sex, parents of males gave higher ratings for whether their children were better other than appearance compared with females, 4.8 versus 3.1 (P = 0.031). DISCUSSION Parents rated their child's neurodevelopment as largely age-appropriate following cranial vault remodeling. These findings are concordant with the majority of formal, standardized testing for this age group. Assessing parental perceptions once children enter school age may reveal increased developmental delays.

Abstract
Craniosynostosis is defined as the premature fusion of one or more cranial sutures resulting in skull deformity. Characteristically, this disorder can cause diverse neurosurgical problems, as well as abnormal skull shape. Intracranial hypertension, hydrocephalus, Chiari malformation and neuropsychological dysfunction are the major neurosurgical concerns in children with craniosynostosis. In this review article, we investigate pathophysiology, characteristics and proper neurosurgical management of these neurosurgical issues, respectively.

Abstract
OBJECTIVE The language and memory functions of children with and without single-suture craniosynostosis (SSC) were compared at school age (mean 7.45 years, standard deviation [SD] 0.54 years). The children in this cohort were originally recruited in infancy and prior to cranial surgery for those with SSC. METHODS Individual evaluations of 179 school-aged children with SSC and 183 controls were conducted (70% of the original cohort) using standardized measures of language, learning, and memory. Parents participated in an interview about specialized education interventions and school progress. Parents and teachers completed questionnaires about language development. RESULTS Children with SSC (cases) obtained lower scores than controls on all measures. The adjusted differences in language, learning, and memory scores were modest, with SD ranging from 0.0 to -0.4 (p values ranged from 0.001 to 0.99). Censored normal regression was used to account for intervention services received prior to the school-age evaluation; this increased case-control differences (SD range 0.1 to -0.5, p value range 0.001 to 0.50). Mean scores for cases in each SSC diagnostic group were lower than those for controls, with the greatest differences observed among children with unilateral coronal craniosynostosis. CONCLUSIONS Children with SSC continue to show poorer performance than controls on language, learning, and memory tasks at early elementary school age, even when controlling for known confounders, although mean differences are small. Multidisciplinary care, including direct psychological assessment, for children with SSC should extend through school age with a specific focus on language and conceptual learning, as these are areas of potential risk. Future research is needed to investigate language, memory, and learning for this population during the middle to high school years.

Abstract
PURPOSE Previous studies have indicated that infants and school-age children with single-suture craniosynostosis (SSC, cases) score modestly but consistently lower than unaffected children (controls) on neurodevelopmental tests. However, sex differences in these functions rarely have been examined, and it is unknown whether potential sex differences vary by case status (cases vs. controls) or location of suture fusion. METHODS We tested 182 cases and 183 demographically matched controls at a mean age of 7.4 years. We measured intellectual abilities with the Wechsler Scale of Intelligence for Children-Fourth Edition. We assessed reading, spelling, and math with a combination of the Wide Range Assessment Test-Fourth Edition, the Test of Word Reading Efficiency, and the Comprehensive Test of Phonological Processing. RESULTS Among both cases and controls, males scored lower on all measures than females with standard score differences ranging from -1.2 to -7.8 for controls (p values from <0.001 to 0.55) and -2.3 to -8.5 for cases (p values from <0.001 to 0.33). For all but one measure, sex differences were slightly larger for cases than controls. Among cases, males were more likely than females to have learning problems (50 vs. 30%, respectively), with the highest level observed among males with unicoronal synostosis (86%). CONCLUSIONS Sex differences in neurodevelopmental abilities among children with SSC are substantial, but not a unique correlate of this disorder as similar differences were observed among controls. Girls and those with sagittal synostosis have the lowest risk for academic problems. Boys with unicoronal synostosis warrant close developmental surveillance.

Abstract
Craniofacial malformations are among the most common birth defects. Although most cases of orofacial clefting and craniosynostosis are isolated and sporadic, these abnormalities are associated with a wide range of genetic syndromes, and making the appropriate diagnosis can guide management and counseling. Patients with craniofacial malformation are best cared for in a multidisciplinary clinic that can coordinate the care delivered by a diverse team of providers.
