Abstract
PURPOSE Nonsyndromic craniosynostosis (NSC) is associated with neurocognitive deficits, and intervention at infancy is standard of care to limit the negative effects of NSC on brain development. In this study, diffusion tensor imaging (DTI) was implemented to investigate white matter microstructure in infants with NSC undergoing cranial vault remodeling, and a comparison was made with white matter development in neurotypical controls. METHODS Infants presenting with NSC (n = 12) underwent DTI scans before and after cranial vault remodeling. Neurotypical infants (n = 5), age matched to NSC patients at preoperative scans, were compared to preoperative DTI scans. Pre- and postoperative NSC scans were compared in aggregate, and the sagittal synostosis (n = 8) patients were evaluated separately. Finally, neurotypical infants from the University of North Carolina/University of New Mexico Baby Connectome Project (BCP), who underwent DTI scans at timepoints matching the NSC pre- and postoperative DTI scans, were analyzed (n = 9). Trends over the same time period were compared between NSC and BCP scans. RESULTS No significant differences were found between preoperative NSC scans and controls. White matter development was more limited in NSC patients than in BCP patients, with microstructural parameters of the corpus body and genu and inferior and superior longitudinal fasciculi consistently lagging behind developmental changes observed in healthy patients. CONCLUSION Infant white matter development appears more limited in NSC patients undergoing cranial vault remodeling relative to that in neurotypical controls. Further investigation is needed to explore these differences and the specific effects of early surgical intervention.

Systematic Review of the Clinical and Experimental Research Assessing the Effects of Craniosynostosis on the Brain. J Craniofac Surg 2023; 34:1160-1164.

Abstract
Although neurocognitive impairment has been considered as the main argument for the surgical treatment of craniosynostosis (CS), recent studies reported subtle deficits in neurological function even in operated patients. However, the cause of these deficits remains poorly understood. This systematic review sought to examine the impact of CS on the brain microstructure, mainly on functional connectivity, and comprehensively summarize the clinical and experimental research available on this topic. A systematic review was performed considering the publications of the last 20 years in PubMed and Web of Science, including relevant human and animal studies of the types of brain-microstructure disturbances in CS. Among the 560 papers identified, 11 were selected for analysis. Seven of those were conducted in humans and 4 in animal models. Resting-state functional magnetic resonance imaging, task-based magnetic resonance imaging, and diffusion tensor imaging were the main instruments used to investigate brain connectivity in humans. The main findings were increased connectivity of the posterior segment of cingulum gyri, reduced interconnectivity of the frontal lobes, and reduced diffusivity on diffusion tensor imaging, which were associated with hyperactivity behaviors and poorer performance on neurocognitive tests. Conversely, despite the lack of evidence of brain dysfunction in animal studies, they reported a tendency toward the development of hyperactive behaviors and impairment of neurocognitive function. Skull restriction caused by CS apparently chronically increases the intracranial pressure and produces white matter injuries. The current evidence supports the contention that an early surgical approach could minimize brain-connectivity impairment in this context.

Abstract
BACKGROUND Although nonsyndromic craniosynostosis has been associated with neurodevelopmental sequelae, a lesser amount of emphasis has been placed on the need for related supportive services. This study assessed the prevalence of such services among children surgically treated for nonsyndromic craniosynostosis and identified predictors of service use. METHODS Parents of children with nonsyndromic craniosynostosis were recruited from an online craniosynostosis support network and surveyed regarding their child's use of various outpatient and school-based services. Multiple stepwise regression was performed to identify predictive variables for each type of intervention. RESULTS A total of 100 surveys were completed. Of these, 45 percent of parents reported use of one or more outpatient support services for their children. The most commonly used services were speech therapy (26.0 percent) and physical therapy (22.0 percent), although the use of services such as psychology/psychiatry increased among older children (18.2 percent in children aged 6 to 10 years). Among school-age children ( n = 49), the majority of parents (65.3 percent) reported school-based assistance for their children, most commonly for academic (46.9 percent) or behavioral (42.9 percent) difficulties. Significant predictive variables ( p < 0.05 following stepwise regression) for increases in various outpatient and school-based services included male sex, African American race/ethnicity, higher parental income, the presence of siblings in the household, increased age at the time of surgery, and sagittal synostosis. CONCLUSIONS Parents of children with nonsyndromic craniosynostosis reported frequent use of outpatient and school-based supportive services throughout childhood. These services may incur a significant burden of care on families. The multifactorial nature of predictive models highlights the importance of cross-disciplinary collaboration to address each child's longitudinal needs.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Understand the craniofacial dysmorphology of craniosynostosis, and the variation of each type. 2. Identify the functional concerns and learn the rationale behind timing of operative intervention. 3. Approach each dysmorphology critically and identify the operative intervention needed to improve form and function 4. Understand and address the specific issues related to syndromic craniosynostosis and be able to delineate management plan. SUMMARY Craniosynostosis is a condition in which premature fusion of one or more cranial sutures lead to abnormal head shape and growth restriction of the brain. Nonsyndromic craniosynostosis occurs in isolation, and usually involves a single suture, whereas syndromic craniosynostosis may involve multiple sutures and is associated with extracraniofacial findings. Although surgical management can be similar, the treatment plan must take into consideration issues specific to the syndromes. This article aims to provide a concise overview of the authors' current understanding regarding the presentation, treatment principle, surgical option, and debates in craniosynostosis.

Examining the Role of Early Diagnostic Imaging for Craniosynostosis in the Era of Endoscopic Suturectomy: A Single Institution Experience. J Craniofac Surg 2022; 33:1363-1368. [PMID: 35132031 DOI: 10.1097/scs.0000000000008534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 01/15/2022] [Indexed: 11/25/2022] Open
Abstract
ABSTRACT Endoscopic suturectomy is a minimally invasive surgical treatment for single-suture craniosynostosis in children between 1 and 4 months of age. This study sought to characterize the role played by diagnostic imaging in facilitating early surgical management with endoscopic suturectomy. The authors also characterized the overall diagnostic utility of imaging in patients assessed for abnormal head shape at their institution, regardless of surgical status. A retrospective cohort of children diagnosed with single-suture synostosis undergoing either primary endoscopic suturectomy or open calvarial reconstruction at the authors' institution from 1998 to 2018 was first reviewed. Of 132 surgical patients, 53 underwent endoscopic suturectomy and 79 underwent open repair. There was no difference in the proportion of endoscopic and open surgery patients imaged preoperatively before (24.5% versus 35.4%; P = 0.24) or after (28.3% versus 25.3%; P = 0.84) craniofacial assessment. Stratifying by historical epoch (1998-2010 versus 2011-2018), there was also no difference found between preoperative imaging rates (63.6% versus 56.4%; P = 0.35). In another cohort of 175 patients assessed for abnormal head shape, 26.9% were imaged to rule out craniosynostosis. Positive diagnostic imaging rates were recorded for suspected unicoronal (100%), metopic (87.5%), lambdoidal (75.0%), sagittal (63.5%), multi-suture (50%), and bicoronal (0%) synostosis. The authors conclude that the use of diagnostic imaging at their institution has not increased despite higher utilization of endoscopic suturectomy and need for expedient identification of surgical candidates. However, their results suggest that imaging may play a greater diagnostic role for suspected bicoronal, sagittal, and multi-sutural synostosis among sutural subtypes of synostosis.

Abstract
Craniosynostosis, the premature closure of cranial sutures, is one of the principal causes of pediatric skull deformities. It can cause aesthetic, neurological, acoustic, ophthalmological complications up to real emergencies. Craniosynostosis are primarily diagnosed with accurate physical examination, skull measurement and observation of the deformity, but the radiological support currently plays an increasingly important role in confirming a more precise diagnosis and better planning for therapeutic interventions. The clinician must know how to diagnose in the earliest and least invasive way for the child. In the past, technological limitations reduced the choices; today, however, there are plenty of choices and it is necessary to use the various types of available imaging correctly. In the future, imaging techniques will probably rewrite the common classifications we use today. We provide an updated review of the role of imaging in this condition, through the ages, to outline the correct choice for the clinician for an early and non-invasive diagnosis.

Abstract
PURPOSE Unicoronal synostosis (UCS) has been associated with reading, language, and social dysfunction. Limited brain function connectivity studies exist for UCS with none devoted to comparing outcomes by side of synostosis (left versus right-sided UCS). METHODS Twelve patients with surgically treated UCS, 7 right-sided and 5 left-sided, were age matched to healthy controls. Resting state functional MRI was acquired in a 3T Siemens TIM Trio scanner (Erlangen, Germany). Data was collected with intrinsic connectivity distribution and seed-connectivity analysis using BioImage Suite (Yale School of Medicine). Region of interest analysis was performed based on Brodmann areas related to emotional, executive, language, motor, and visuo-spatial function. Significance was set at P < 0.05. RESULTS Compared to controls, all UCS patients demonstrated decreased connectivity in areas of the parietal and temporal cortices responsible for visuo-motor coordination and language function. Right UCS patients demonstrated decreased intrinsic connectivity in regions related to complex motor movement and proprioception relative to control subjects. Left UCS patients demonstrated decreased seed connectivity between regions of the parietal lobe and occipital lobe related to motor coordination, visual function, and language compared to right UCS patients. CONCLUSION Unicoronal synostosis had decreased functional connectivity in regions associated with memory, visual information processing, and motor function. Moreover, left-sided UCS had decreased connectivity in circuits for motor coordination and language when compared to right-sided UCS. This study provides data suggestive of long-term sequelae of UCS that varies by sidedness, which may be responsible for neurocognitive impairments found in previous cognitive analyses.
