“…This explains the observation that older infants with sagittal synostosis present with a smaller anterior fontanelle. An interesting notion to consider is the phenomenon of delayed synostosis of uninvolved sutures or even pansynostosis (premature fusion of all sutures) after surgical intervention (Greene, 1998;Jenkins et al 2013;Yarbrough et al 2014;Sivakumar et al 2015). With our findings indicating a tendency to early closure at metopic and coronal sutures in the sagittal synostosis cohort, it is worthwhile to investigate the effects of the surgery and the synostosis on the uninvolved sutures separately.…”

“…The increased duration of anesthesia and the larger volume of blood transfusion during any type of craniofacial surgery have been associated with potentially poor neurodevelopmental outcomes in patients later in life (Tunc ßbilek et al 2005;Stricker & Fiadjoe, 2014;Bonfield et al 2016). Since these surgeries are typically performed in the first 6 months of age, it is important to identify the optimal time to intervene for best surgical outcome while having the least detrimental impact to the patient (Yarbrough et al 2014;Sivakumar et al 2015;Bergquist et al 2016;Persing, 2016;Mann et al 2017). An increased understanding of the shape changes and suture closure patterns that occur in SCS compared with normal children in the first 6 months of age would provide valuable information in pursuit of this goal.…”

Cranial growth in isolated sagittal craniosynostosis compared with normal growth in the first 6 months of age

Sagittal craniosynostosis (SCS), the most common type of premature perinatal cranial suture fusion, results in abnormal head shape that requires extensive surgery to correct. It is important to find objective and repeatable measures of severity and surgical outcome to examine the effect of timing and technique on different SCS surgeries. The purpose of this study was to develop statistical models of infant (0–6 months old) skull growth in both normative and SCS subjects (prior to surgery). Our goal was to apply these models to the assessment of differences between these two groups in overall post‐natal growth patterns and sutural growth rates as a first step to develop methods for predictive models of surgical outcome. We identified 81 patients with isolated, non‐syndromic SCS from Seattle Children's Craniofacial Center patient database who had a preoperative CT exam before the age of 6 months. As a control group, we identified 117 CT exams without any craniofacial abnormalities or bone fractures in the same age group. We first created population‐level templates from the CT images of the SCS and normal groups. All CT images from both groups, as well as the canonical templates of both cohorts, were annotated with anatomical landmarks, which were used in a growth model that predicted the locations of these landmarks at a given age based on each population. Using the template images and the landmark positions predicted by the growth models, we created 3D meshes for each week of age up to 6 months for both populations. To analyze the growth patterns at the suture sites, we annotated both templates with additional semi‐landmarks equally spaced along the metopic, coronal, sagittal and lambdoidal cranial sutures. By transferring these semi‐landmarks to meshes produced from the growth model, we measured the displacement of the bone borders and suture closure rates. We found that the growth at the metopic and coronal sutures were more rapid in the SCS cohort than in the normal cohort. The antero‐posterior displacement of the semi‐landmarks also indicated a more rapid growth in the sagittal plane in the SCS model than in the normal model. Statistical templates and geometric morphometrics are promising tools for understanding the growth patterns in normal and synostotic populations and to produce objective and reproducible measurements of severity and outcome. Our study is the first of its kind to quantify the bone growth for the first 6 months of life in both normal and sagittal synostosis patients.

“…Finally, while Kim et al 9 suggested visible head deformity was the most common presenting sign for diagnosis, our study found radiologic imaging to be the most common method of diagnosing idiopathic secondary stenosis. Often it was described on radiology in the literature as “closed sutures”, “copper beaten”, “thumb printing”, or “scalloping” 2,8,11–16 . In almost all recorded cases in the literature, the radiographic method employed was x-ray, although Jenkins et al 17 described using computed tomography to show their patient having pansynostosis.…”

Background: Primary craniosynostosis is a congenital craniofacial disorder in which cranial sutures prematurely close. Iatrogenic secondary stenosis is abnormal cranial suture closure caused by surgical manipulation of the suture. In contrast, idiopathic secondary stenosis develops in a suture that did not undergo surgical manipulation. The objective of this systematic review was to consolidate and characterize the incidence, classification, and management of idiopathic secondary stenosis in the literature. Methods: Literature from PubMed, Web Of Science, and EM-BASE from 1970 to March 2022 was reviewed. The following information was extracted for individual patients: incidence of idiopathic secondary stenosis, index primary craniosynostosis, primary surgical correction, presenting signs of secondary stenosis, management, and further complications. Results: Seventeen articles detailing 1181 patients were included. Ninety-one developed idiopathic secondary stenosis (7.7%). Only 3 of these patients were syndromic. The most common index craniosynostosis was sagittal synostosis (83.5%). The most common suture undergoing idiopathic secondary stenosis was the coronal suture (91.2%). Patients presented at a median age of 24 months. The most common presenting sign was a radiologic finding (85.7%), although some patients presented with headache or head deformity. Only 2 patients, both syndromic, had complications following surgical correction of secondary stenosis.Conclusions: Idiopathic secondary stenosis is a rare, long-term complication following index surgical repair of craniosynostosis. It can occur following any surgical technique. It most commonly affects the coronal suture but can affect any of the sutures, including pansynostosis. Surgical correction is curative in nonsyndromic patients.

However, the prevention of new bone formation is critical in certain clinical settings, such as premature epiphyseal fusion of long bones (10,11), and after the craniosynostosis surgery (5,14,16).…”

AIM:To investigate the utility of two different interpositional materials (muscle graft vs. fascia flap) for preventing the osseous reunion of skull bone defect including the coronal suture line in rats. MATERIAL and METHODS:A total of 32 male Sprague-Dawley rats were divided into 2 groups (n=16 for each) after the formation of bilateral coronal bone defect, based on the interpositional materials used to prevent re-ossification; the rats were divided into the muscle graft (MG) group and the fascial flap (FF) group. In each group, the other side of the coronal suture served as the control. The rats were sacrificed at postoperative 4 weeks or 8 weeks for histopathological, radiological, and microbiologic investigations. RESULTS:At postoperative 8 weeks, there was partial reunion in the defects with bony tissue in both the groups; no obvious differences were noted between the groups on radiological examination.The defect content involved bone and fibrous tissue in the MG group and bony bridges and loose connective tissue in the FF group. New bone formation was moderate, marked, and extreme and the reduction in defect size was marked, moderate, and extreme in the MG, FF, and control groups, respectively. CONCLUSION:Our findings revealed that neither the temporal MG nor the temporal FF were able to achieve complete prevention of re-ossification of the skull bone defects including the coronal suture line; further, neither material was superior to the other.
