Abstract
BACKGROUND Surgical correction of unicoronal craniosynostosis (UCS) is highly complex due to its asymmetric appearance. Although fronto-orbital advancement (FOA) is a versatile technique for craniosynostosis correction, harmonization of the orbital bandeau in UCS is difficult to predict. This study evaluates the biomechanics of the orbital bandeau using different patterns and varying characteristics of inner cortical bone layer osteotomies in a finite element (FE) analysis. METHOD An FE model was created using the computed tomography (CT) scan of a 6.5-month-old male infant with a right-sided UCS. The unaffected side of the orbital bandeau was virtually mirrored, and anatomical correction of the orbital bandeau was simulated. Different combinations of osteotomy patterns, numbers, depths, and widths were examined (n = 48) and compared to an uncut model. RESULTS Reaction forces and maximum stress values differed significantly (p < 0.01) among osteotomy patterns and between each osteotomy characteristic. Regardless of the osteotomy pattern, higher numbers of osteotomies significantly (p < 0.05) correlated with reductions in reaction force and maximum stress. An X-shaped configuration with three osteotomies deep and wide to the bone was biomechanically the most favorable model. CONCLUSION Inner cortical bone layer osteotomy might be an effective modification to the conventional FOA approach in terms of predictable shaping of the orbital bandeau.

Abstract
PURPOSE Sagittal synostosis is the most common isolated craniosynostosis. Surgical treatment of this synostosis has been extensively described in the global literature, with promising outcomes when it is performed in the first 12 months of life. However, in some cases, patients older than 12 months arrive at the craniofacial center with this synostosis. A comprehensive study on efficacy and perioperative outcomes has yet to be fully explored in this population. This systematic review and meta-analysis aimed to assess the available evidence of surgical outcomes for the treatment of sagittal synostosis among older patients to analyze the efficacy and safety of synostosis surgery in this unique population. METHODS PubMed, Embase, and Scopus were searched for studies published from inception to March 2024 reporting surgical outcomes of synostosis surgery in older patients (> 12 months) with isolated sagittal synostosis. The main outcome was the reoperation rate, with secondary endpoints including transfusion rates, aesthetic outcomes, and surgical complications. RESULTS Nine studies were included in the final analysis. The pooled proportion of the reoperation rate was 1%. The rate of excellent aesthetic results was 95%. The need for transfusion associated with the procedures was 86%, and finally, surgical complications attained a pooled ratio of 2%, indicating minimal morbidity associated with the surgical repair. CONCLUSION Sagittal synostosis surgery is a safe and effective procedure to perform in older patients; this meta-analysis suggests that open surgery confers a significant rate of excellent aesthetic results with a low reoperation rate and minimal complications associated with the intervention. Future research with direct comparisons among different techniques will validate the findings of this study, which will all contribute to the rigor of synostosis management.

Abstract
BACKGROUND Sagittal synostosis is the most common type of premature suture closure, and many surgical techniques are used to correct scaphocephalic skull shape. Given the rarity of direct comparisons of different surgical techniques for correcting craniosynostosis, this study compared outcomes of craniotomy combined with springs and H-craniectomy for nonsyndromic sagittal synostosis. METHODS Comparisons were performed using available preoperative and postoperative imaging and follow-up data from the 2 craniofacial national referral centers in Sweden, which perform 2 different surgical techniques: craniotomy combined with springs and H-craniectomy (the Renier technique). The study included 23 pairs of patients matched for sex, preoperative cephalic index, and age. Cephalic index, total intracranial volume (ICV), and partial ICV were measured before surgery and at 3 years of age, with volume measurements compared against those of preoperative and postoperative controls. Perioperative data included operation time, blood loss, volume of transfused blood, and length of hospital stay. RESULTS Craniotomy combined with springs resulted in less bleeding and lower transfusion rates than H-craniectomy. Although the spring technique requires 2 operations, the mean total operation time was similar for the methods. Of the 3 complications that occurred in the group treated with springs, 2 were spring-related. The compiled analysis of changes in cephalic index and partial volume distribution revealed that craniotomy combined with springs resulted in superior morphologic correction. CONCLUSION The findings showed that craniotomy combined with springs normalized cranial morphology to a greater extent than H-craniectomy based on changes in cephalic index and total and partial ICVs over time.

Abstract
This study constructed deep learning models using plain skull radiograph images to predict the accurate postnatal age of infants under 12 months. Utilizing the results of the trained deep learning models, it aimed to evaluate the feasibility of employing major changes visible in skull X-ray images for assessing postnatal cranial development through gradient-weighted class activation mapping. We developed DenseNet-121 and EfficientNet-v2-M convolutional neural network models to analyze 4933 skull X-ray images collected from 1343 infants. Notably, allowing for a ± 1 month error margin, DenseNet-121 reached a maximum corrected accuracy of 79.4% for anteroposterior (AP) views (average: 78.0 ± 1.5%) and 84.2% for lateral views (average: 81.1 ± 2.9%). EfficientNet-v2-M reached a maximum corrected accuracy 79.1% for AP views (average: 77.0 ± 2.3%) and 87.3% for lateral views (average: 85.1 ± 2.5%). Saliency maps identified critical discriminative areas in skull radiographs, including the coronal, sagittal, and metopic sutures in AP skull X-ray images, and the lambdoid suture and cortical bone density in lateral images, marking them as indicators for evaluating cranial development. These findings highlight the precision of deep learning in estimating infant age through non-invasive methods, offering the progress for clinical diagnostics and developmental assessment tools.

Abstract
OBJECTIVE Disparities in insurance and socioeconomic status (SES) may impact surgical management and subsequent postoperative outcomes for patients with craniosynostosis. This systematic review summarizes the evidence on possible differences in surgical care, including procedure type, age at surgery, and differences in surgical outcomes such as complications, length of hospital stay, and child development based on SES. DESIGN The databases Scopus, PubMed, and CINAHL were searched between May and July 2022. Following PICO criteria, studies included focused on patients diagnosed with craniosynostosis; corrective surgery for craniosynostosis; comparison of insurance, income, or zip code; and surgical management of postoperative outcomes. RESULTS The initial search yielded 724 articles. After three stages of screening, 13 studies were included. Assessed outcomes included: type of procedure (6 articles), age at time of surgery (3 articles), post-operative complications (3 articles), referral delay (2 articles), length of stay (2 articles), hospital costs (2 articles), and child development (1 article). Of the studies with significant results, insurance type was the main SES variable of comparison. While some findings were mixed, these studies indicated that patients with public medical insurance were more likely to experience a delay in referral, undergo an open rather than minimally-invasive procedure, and have more complications, longer hospitalization, and higher medical charges. CONCLUSIONS This study demonstrated that SES may be associated with several differences in the management of patients with craniosynostosis. Further investigation into the impact of SES on the management of patients with craniosynostosis is warranted to identify possible interventions that may improve overall care.

Abstract
SUMMARY Premature fusion of the lambdoid suture is the most uncommon single-suture synostosis. It presents with a classic "windswept" appearance, a trapezoid-shaped head, and significant skull asymmetry notable for an ipsilateral mastoid bulge and contralateral frontal bossing. Because of the rarity of lambdoid synostosis, little is known about optimal techniques for its treatment. In particular, the proximity of the lambdoid suture to critical intracranial structures such as the superior sagittal and transverse sinuses represents a potential for significant intraoperative bleeding. Prior work has shown that parietal asymmetry persists after repair in these cases. In this article, the authors present a technique for the treatment of unilateral lambdoid craniosynostosis along with two representative cases. This calvarial vault remodeling technique requires the removal of both ipsilateral and contralateral parietal bones. These are moved across hemispheres and reinset on opposite sides to help correct the parietal asymmetry. Obliquely orientated barrel stave osteotomies are performed to provide a safe mechanism for correction of occipital flattening. The authors' early results show improvement in correction of volume asymmetry 1 year postoperatively relative to patients treated with prior calvarial vault remodeling techniques. The authors believe the technique presented here corrects the windswept appearance in patients with lambdoid craniosynostosis and also reduces the potential for complications. Further work will be necessary to confirm this technique's long-term efficacy in a larger cohort.

Abstract
BACKGROUND Open middle and posterior cranial vault expansion (OPVE) or endoscopic (ES) strip craniectomy are two surgical techniques for normalization of head shape in isolated sagittal synostosis. This study aims to compare 2-year cranial morphometrics after these two approaches. METHODS The authors performed morphometric analysis on preoperative [time (T) 0], immediately postoperative (T1), and 2-year (T2) postoperative computed tomographic scans of patients who underwent OPVE or ES before 4 months of age. Perioperative data and morphometrics were compared between the two groups and age-matched controls. RESULTS Nineteen patients were included in the ES cohort, 19 age-matched patients were included in the OPVE cohort, and 57 were included as controls. Median surgery time and blood transfusion volume were less for the ES approach (118 minutes and 0 cc, respectively) compared with OPVE (204 minutes and 250 cc, respectively). Anthropometric measurements after OPVE were closer in normal controls at T1 compared with ES, but the skull shapes were comparable at T2. In the midsagittal plane, anterior vault was higher after OPVE at T2 compared with both ES and controls, but the posterior length was shorter and closer to controls than in the ES cohort. Cranial volumes were like controls for both cohorts at T2. There was no difference in complication rate. CONCLUSIONS Both OPVE and ES techniques result in normalization of cranial shape in patients with isolated sagittal synostosis after 2 years with minimal morphometric differences. Family decision-making between the two approaches should be based on age at presentation, avoidance of blood transfusion, scar pattern, and availability of helmet molding and not on expected outcome.

Abstract
Craniosynostosis is an atypical skull shape characterized by the premature fusion of cranial sutures. It is one of the most common congenital anomalies encountered by craniofacial surgeons, with a prevalence of one in every 2000-2500 births. It is classified into two main types: syndromic and nonsyndromic. In syndromic, the patient presents with other abnormalities involving the trunk, face, or extremities. While in nonsyndromic the only anomy is the premature fusion, which usually involves one suture; the most common subtypes are unicoronal, sagittal, bicoronal, metopic, and lambdoid. As a consequence, premature fusion before its natural time restricts the space for the brain to grow, increases intracranial pressure, causes damage to the brain tissue, and affects the development of the child. This review comprehensively provides a detailed overview of nonsyndromic craniosynostosis and aims to highlight the importance of early and accurate diagnosis, and determining the most suitable intervention, whether surgical or conservative modalities. The optimal treatment approach produces the most favorable aesthetic and functional outcomes.

Abstract
OBJECTIVE Precise planning and execution is key for neuroendoscopic interventions, which can be based on different available aiding technologies. The aim of this retrospective study is to report a case-based use of guided neuroendoscopy and to develop a stratification algorithm for the available technologies. METHODS We reviewed consecutive neuroendoscopic cases performed at our center from 2016 to 2018. We distinguished between patients receiving a new burr hole (group A) and those with a preexisting burr hole (group B). Case-specific technical requirements for procedure planning and execution, complication rate, surgical outcome, and possible subsequent surgery were evaluated. From this experience, a stratification system was developed to tailor the available guiding technologies. RESULTS A total of 309 neuroendoscopic interventions in 243 patients were included in the present study. The cases included hydrocephalic (81.6%) and nonhydrocephalic (18.4%) conditions. The interventions were supported by coordinate-based (group A, n = 49; group B, n = 67), guide-based (group A, n = 42; group B, n = 0), ultrasound-guided (group A, n = 50; group B, n = 7), or navigated augmented reality-guided (group A, n = 85; group B, n = 9) techniques. The overall complication rate was 4.5%. Stratified by the surgical indication, fontanel status, entry point localization, presence of a preexisting burr hole, ventricular size, and number of targets, an approach toward image-guided neuroendoscopy is suggested. CONCLUSIONS Planning and technical guidance is essential in neuroendoscopic procedures. The stratified decision-making algorithm for different available technologies aims to achieve lower cost and time consumption, which was found to be safe and efficient. Further investigations are warranted to deliver solid data on procedure efficiency.

Abstract
Scaphocephaly is the most common type of craniosynostosis and various surgical techniques are used for treatment. Due to late postoperative changes of the head shape, long-term outcome data is important for evaluating any new surgical technique. At our institution, minimally invasive strip craniectomy without regular helmet therapy is the standard treatment in scaphocephalic patients. Between October 2021 and February 2023, we retrospectively examined the skull shape of patients who underwent minimally invasive strip craniectomy for scaphocephaly using a 3D surface scan technique. The cephalic index (CI), the need for helmet therapy and additional cosmetic outcome parameters were investigated. We included 70 patients (72.5% male). The mean follow-up time was 46 (10-125) months and the mean CI was 75.7 (66.7-85.2). In 58 patients, the final cosmetic result was rated as "excellent/good" (mean CI: 76.3; 70.4-85.0), in 11 as "intermediate" (mean CI: 73.3; 66.7-77.6), and in one case as "unsatisfactory" (CI 69.3). The presence of a suboccipital protrusion was associated with a "less than good" outcome. The CI correlated significantly with the overall outcome, the presence of frontal bossing, and the interval between scan and surgery (age at scan). Minimally invasive strip craniectomy is an elegant and safe method to correct scaphocephaly. Our data show good cosmetic results in the long term even without regular postoperative helmet therapy.

Patient-reported outcome measures more than fifteen years after treatment of sagittal or metopic craniosynostosis: a prospective cohort study. Childs Nerv Syst 2024; 40:769-777. [PMID: 37914832 PMCID: PMC10891201 DOI: 10.1007/s00381-023-06202-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 10/24/2023] [Indexed: 11/03/2023]
Abstract
PURPOSE To evaluate the long-term anthropometric measurements, cosmetic satisfaction, and other patient-reported outcome measures (PROMs) of patients who underwent surgical treatment or observation only of sagittal or metopic single-suture craniosynostosis (SSC). METHODS A prospective study was designed for all patients diagnosed with non-syndromic sagittal and metopic craniosynostosis at the British Columbia Children's Hospital, Vancouver, Canada, in the period July 1986 to July 2006. After a minimum of 15 years post-diagnosis, all eligible patients were invited to fill out the Craniofacial Surgery Outcomes Questionnaire (CSO-Q) and to attend a scheduled follow-up appointment for the collection of anthropometric measurements. A descriptive analysis of the cosmetic results was performed. Statistical analyses compared the differences in anthropometric measurements between treated and non-treated patients. RESULTS Of the 253 eligible patients, 52 participants were willing to share patient data for use in the study. Of those 52 former patients, 36 (69.2%) filled out and returned the CSO-Q and 23 (44.2%) attended the follow-up appointment. The mean follow-up period between surgical treatment and the CSO-Q was 20.2 ± 2.5 years and between surgical treatment and the follow-up appointment was 20.9 ± 2.7 years. In patients with sagittal SSC, the mean cephalic index (CI) was significantly larger in treated than in non-treated patients (74.6 versus 69.1, p = 0.04), while the mean pupillary distance and forehead to back index were significantly smaller (pupillary distance 6.0 cm versus 6.7 cm [p = 0.04] and forehead to back index 19.6 cm versus 21.1 cm [p = 0.03]). Focusing more on the patient reported outcome measures, overall cosmetic satisfaction was found to be high (80.6%) and no differences were found between sagittal and metopic synostosis patients, nor between treated or non-treated craniosynostosis patients. Overall outcomes regarding self-esteem (RSES) and fear of negative evaluation (FNE) were comparable with population based outcomes. CONCLUSION This is the first prospective study of sagittal and metopic craniosynostosis patients regarding long-term anthropometric outcome and patient reported outcome measures, including patients who were treated surgically and those who received observation only. Although study participation two decades after initial diagnosis was difficult to obtain, our data provide a platform from which one can develop an inclusive and uniform approach to assess patients' subjective cosmetic satisfaction using the CSO-Questionnaire and might be useful in preoperative counseling and psychosocial care for patients and their families.

Abstract
Endoscopic strip craniectomy followed by postoperative remodeling helmet therapy for scaphocephaly is widely accepted, but the requirement of several helmets might burden patients or their families. This study examined whether craniectomy via a bicoronal approach without molding helmet therapy is worth considering. The authors retrospectively reviewed patients with nonsyndromic sagittal suture synostosis who underwent the modified Renier H technique between 2016 and 2021. We collected data on preoperative and postoperative cephalic index (CI), operative time, estimated blood loss, and blood transfusion rates. The authors also examined all related literature in English describing endoscopic craniectomy with postoperative helmet molding therapy for sagittal suture craniosynostosis. Among 17 patients, the average operative time was 92.2±15.6 minutes, the mean estimated blood loss was 35.8±22.4 mL, and a blood transfusion was needed for 9 patients (52.9%). The mean preoperative and postoperative CIs were 69.1±2.6 and 78.4±2.2, respectively. A comparison of the literature review with the authors' results showed that their procedures required a slightly longer operative time and a higher frequency of blood transfusions. There are no significant differences in blood loss or preoperative and postoperative CIs reported in the literature. The open procedure required a higher operative time than endoscopic suturectomy. However, dealing with bleeding is more challenging with endoscopic suturectomy. The cost of the helmets and the duration patients have to wear them, which might be burdensome for the patients or their families when determining the optimal minimally invasive treatment, should also be considered.

Abstract
To describe the process of developing a craniosynostosis decision aid. We conducted a mixed-methods exploratory study between August 2019 and March 2020 to develop a decision aid about surgical treatment for single suture craniosynostosis. A single tertiary care academic children's hospital. The decision aid development team consisted of surgeons, research fellows, a clinical nurse practitioner, clinical researchers with expertise in decision science, and a university-affiliated design school. Qualitative interviews (N = 5) were performed with families, clinicians (N = 2), and a helmeting orthotist to provide feedback on decision aid content, format, and usability. After cycles of revisions and iterations, 3 related decision aids were designed and approved by the marketing arm of our institution. Distinct booklets were created to enable focused discussion of treatment options for the 3 major types of single suture craniosynostosis (sagittal, metopic, unicoronal). Three decision aids representing the 3 most common forms of single suture craniosynostosis were developed. Clinicians found the decision aids could help facilitate discussions about families' treatment preferences, goals, and concerns. We developed a customizable decision aid for single suture craniosynostosis treatment options. This tool lays the foundation for shared decision-making by assessing family preferences and providing clear, concise, and credible information regarding surgical treatment. Future research can evaluate this tool's impact on patient-clinician discussions about families' goals and preferences for treatment.

Abstract
BACKGROUND AND OBJECTIVE Computer-aided surgical simulation (CASS) can be used to virtually plan ideal outcomes of craniosynostosis surgery. Our purpose was to create a workflow analyzing the accuracy of surgical outcomes relative to virtually planned fronto-orbital advancement (FOA). METHODS Patients who underwent FOA using CASS between October 1, 2017, and February 28, 2022, at our center and had postoperative computed tomography within 6 months of surgery were included. Virtual 3-dimensional (3D) models were created and coregistered using each patient's preoperative and postoperative computed tomography data. Three points on each bony segment were used to define the object in 3D space. Each planned bony segment was manipulated to match the actual postoperative outcome. The change in position of the 3D object was measured in translational (X, Y, Z) and rotational (roll, pitch, yaw) aspects to represent differences between planned and actual postoperative positions. The difference in the translational position of several bony landmarks was also recorded. Wilcoxon signed-rank tests were performed to measure significance of these differences from the ideal value of 0, which would indicate no difference between preoperative plan and postoperative outcome. RESULTS Data for 63 bony segments were analyzed from 8 patients who met the inclusion criteria. Median differences between planned and actual outcomes of the segment groups ranged from -0.3 to -1.3 mm in the X plane; 1.4 to 5.6 mm in the Y plane; 0.9 to 2.7 mm in the Z plane; -1.2° to -4.5° in pitch; -0.1° to 1.0° in roll; and -2.8° to 1.0° in yaw. No significant difference from 0 was found in 21 of 24 segment region/side combinations. Translational differences of bony landmarks ranged from -2.7 to 3.6 mm. CONCLUSION A high degree of accuracy was observed relative to the CASS plan. Virtual analysis of surgical accuracy in FOA using CASS was feasible.

Abstract
PURPOSE This study provides a systematic review on cosmetic satisfaction and other patient-reported outcomes (PROMs) of patients who underwent surgical treatment of SSC. METHODS A systematic review of all articles published from inception to 1 June 2022 was performed. Articles were included if they reported on subjective assessment of cosmetic satisfaction or other PROMs by patients or their families using questionnaires or interviews. RESULTS Twelve articles, describing 724 surgical treatments of SSC, met the inclusion criteria. Cosmetic satisfaction was evaluated in the following ways: 1) use of the VAS score, binary questions or a 5-point scale to rate general, facial or skull appearance; 2) use of an aesthetic outcome staging in which personal opinion was added to the treating surgeon's opinion; and 3) use of an evaluation of anatomical proportions of the skull and face. A trend towards an overall improvement in cosmetic satisfaction following surgical treatment of SSC was observed. Reported PROMs included general health, socioeconomic status, patients' and their families' rating of the normalcy and noticeability of their appearance and how much this bothered them, and patients' answers to the Youth Quality of Life with Facial Differences (YQOL-FD) questionnaire. No clear overall trend of the reported PROMs was identified. CONCLUSION This systematic review illuminates that there is a wide variation in outcomes for evaluating cosmetic satisfaction and other PROMs of patients who underwent surgical treatment of SSC, suggesting that further research is needed to develop an inclusive and uniform approach to assess these outcomes.

Abstract
Sagittal synostosis is a condition caused by the fused sagittal suture and results in a narrowed skull in infants. Spring-assisted cranioplasty is a correction technique used to expand skulls with sagittal craniosynostosis by placing compressed springs on the skull before six months of age. Proposed methods for surgical planning in spring-assisted sagittal craniosynostosis correction provide information only about the skull anatomy or require iterative finite element simulations. Therefore, the selection of surgical parameters such as spring dimensions and osteotomy sizes may remain unclear and spring-assisted cranioplasty may yield sub-optimal surgical results. The aim of this study is to develop the architectural structure of an automated tool to predict post-operative surgical outcomes in sagittal craniosynostosis correction with spring-assisted cranioplasty using machine learning and finite element analyses. Six different machine learning algorithms were tested using a finite element model which simulated a combination of various mechanical and geometric properties of the calvarium, osteotomy sizes, spring characteristics, and spring implantation positions. Also, a statistical shape model representing an average sagittal craniosynostosis calvarium in 5-month-old patients was used to assess the machine learning algorithms. XGBoost algorithm predicted post-operative cephalic index in spring-assisted sagittal craniosynostosis correction with high accuracy. Finite element simulations confirmed the prediction of the XGBoost algorithm. The presented architectural structure can be used to develop a tool to predict the post-operative cephalic index in spring-assisted cranioplasty in patients with sagittal craniosynostosis can be used to automate surgical planning and improve post-operative surgical outcomes in spring-assisted cranioplasty.

Abstract
OBJECTIVE Endoscopic suturectomy is a widely practiced surgical option for infants with craniosynostosis. But the efficacy and safety of the procedure remain unclear in syndromic patients. This study aims to evaluate the efficacy and safety of endoscopic suturectomy for patients with syndromic craniosynostosis. METHODS From January 2013 to December 2020, 242 patients underwent endoscopic suturectomy at our institution. The surgical outcome was determined to be favorable or unfavorable based upon the necessity of an additional cranial surgery upon the last follow-up. First, we analyzed the outcomes of 26 syndromic craniosynostosis patients who have followed up for over a year. Second, we compared the outcomes between the syndromic (N=12) and nonsyndromic (N=11) patients with bilateral coronal synostosis who have followed up for over a year. RESULTS Twenty-three out of 26 syndromic craniosynostosis patients (88%) showed favorable outcomes without significant complications. In the analysis for bilateral coronal synostosis patients, 11 of 12 syndromic patients (92%) presented favorable outcomes, and all nonsyndromic patients showed favorable outcomes. No significant differences were observed in various anthropometric indices (cranial index, intracranial volume, anterior cranial height, anterior cranial base length, and cranial height-length index) and surgical outcomes between syndromic and nonsyndromic groups. CONCLUSIONS Endoscopic suturectomy has the potential to be a surgical option for syndromic craniosynostosis. Even for patients with unfavorable outcomes, endoscopic suturectomy could serve as a bridge treatment for infants to counter cranial deformation before additional extensive surgery.

[PMID: 37762999 PMCID: PMC10531492 DOI: 10.3390/jcm12186059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 09/13/2023] [Accepted: 09/14/2023] [Indexed: 09/29/2023] Open
Abstract
(1) Background: Patients with unicoronal craniosynostosis (UCS) often show torticollis which can result from either an ocular cause or contraction of the sternocleidomastoid muscle. For clinicians, it is crucial to know the prevalence of ocular torticollis (OT) to ensure appropriate referral for treatment. Furthermore, associated ophthalmic features with OT in these patients are scarcely described. The aim of this study was to determine the prevalence of OT in non-syndromic UCS patients and investigate its associated ophthalmic features. (2) Methods: In this descriptive cross-sectional study medical records of non-syndromic UCS patients treated between 1994-2022 in one tertiary care hospital in The Netherlands were retrospectively reviewed. Collected data included: diagnosis and type of torticollis, binocular single vision (BSV), strabismus, ocular motility, alphabetical patterns, refractive error, and amblyopia. Patients were classified as OT, based on their ophthalmic and/or orthoptic diagnosis. Prevalence was determined with the 95% CI using the Clopper-Pearson exact test. Associations between OT and the ophthalmic features were determined using Chi-square or Fishers' exact test and its effect size was calculated using Cramer's V. (3) Results: In total, 146 patients were included, of whom 57 had torticollis. An ocular cause for the torticollis was found in 54 patients. The prevalence of OT was 37% (n = 146; 95% CI [0.292-0.454]). Significant associations were found between OT and strabismus (p < 0.001), ocular motility abnormalities (p < 0.001), alphabetical patterns (p < 0.001), and amblyopia (p = 0.002). BSV (p = 0.277) and refractive error (p = 1.0) were not significantly associated with OT. However, in OT the BSV was relatively poor (42.1%) and more frequently absent (26.3%) compared to the non-torticollis group (7% poor and 16.3% absent). In both groups, excyclotorsion was predominantly present (62.3%). (4) Conclusions: In 95% of cases, torticollis in UCS patients is ocular-related. Overall, one in three patients with UCS have OT. This study emphasizes the importance of a timely referral of all patients with UCS with torticollis to an orthoptist and/or ophthalmologist, specialized in diagnosing and treatment of OT, before considering physiotherapy.

Comparative Analysis of 2D and 3D Metrics for Evaluation of Postoperative Outcomes Following Endoscopic Suturectomy for Sagittal Craniosynostosis. J Craniofac Surg 2023; 34:1699-1704. [PMID: 37477605 DOI: 10.1097/scs.0000000000009485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 05/09/2023] [Indexed: 07/22/2023] Open
Abstract
To assess whether 3-dimensional (3D) volumetrics can be used to track and evaluate postoperative course of patients treated with endoscopic suturectomy for nonsyndromic sagittal synostosis, we compared changes in 2-dimensional (2D) measurements along with 3D volumetric correlates throughout the period of helmet therapy. Forty-six patients treated at our institution with endoscopic suturectomy for sagittal synostosis were retrospectively reviewed. Head circumference (HC), cephalic index (CI), and total cranial volumes (TCVs) were measured at 3 timepoints following surgery using optical surface scans obtained for helmet orthotics. All measurements showed significant differences between timepoints on the analysis of variance ( P <0.001). There was a significant correlation between CI and TCV (r=0.35, P =0.004) and between HC and TCV (r=0.81, P <0.001). The normalized rate of change over the course of treatment was significantly higher for TCV (36.7%) than for CI (8.8%) and HC (8.4%, P <0.001), with no difference between HC and CI. The authors conclude that 3D metrics were able to reliably follow the course of postoperative 2D metrics. There was a direct and linear correlation between HC and CI with TCV. Total cranial volumes showed the highest rate of sustained change at every timepoint. Although CI and HC plateau after the first measurement, TCV continues to adapt over the course of treatment. These results demonstrate the feasibility and value of volumetrics from 3D imaging to provide a more comprehensive evaluation of postoperative surgical outcomes than traditional 2D metrics without the ionizing radiation traditionally utilized for CT to obtain 3D metrics.

Abstract
Although many published studies have investigated the benefits of tranexamic acid (TXA) in reducing perioperative bleeding, no large meta-analysis has been conducted to demonstrate its overall benefit. Methods A systematic review was performed by following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. PubMed, Cochrane, Ovid, Embase, Web of Science, ClinicalTraisl.Gov, and Scopus databases were searched for articles reporting the benefit of TXA in reducing perioperative bleeding in craniosynostosis surgery from establishment through October 2022. The results of our meta-analysis were pooled across the studies using a random-effects model, and presented as a weighted mean difference with 95% confidence interval (95% CI). Results The database search yielded 3207 articles, of which 27 studies with a corresponding number of 9696 operations were eligible. The meta-analysis included only 18 studies, accounting for 1564 operations. Of those operations, 882 patients received systemic TXA, whereas 682 patients received placebo (normal saline), no intervention, low dose TXA, or other control substances. This meta-analysis demonstrated a significant beneficial effect of TXA in reducing perioperative bleeding, particularly when compared with other controlled substances, with a weighted mean difference of -3.97 (95% CI = -5.29 to -2.28). Conclusions To our knowledge, this is the largest meta-analysis in the literature investigating the benefit of TXA in reducing perioperative blood loss in craniosynostosis surgery. We encourage implementing TXA-protocol systems in hospitals after the appraisal of the data presented in this study.

A population-based study. Eur J Pediatr 2023; 182:2379-2392.

Abstract
Understanding hospital service use among children with a diagnosis of craniosynostosis (CS) is important to improve services and outcomes. This study aimed to describe population-level trends, patterns, and factors influencing hospitalizations for craniosynostosis in Western Australia. Data on live births (1990-2010; n = 554,624) including craniosynostosis, episodes of death, demographic, and perinatal factors were identified from the midwives, birth defects, hospitalizations, and death datasets. Information on craniosynostosis and non-craniosynostosis-related admissions, cumulative length of hospital stay (cLoS), intensive care unit, and emergency department-related admissions were extracted from the hospitalization dataset and linked to other data sources. These associations were examined using negative binomial regression presented as annual percent change and associations of hospitalizations by age groups, demographic, and perinatal factors were expressed as incidence rate ratio (IRR). We found an increasing trend in incident hospitalizations but a marginal decline in cLoS for craniosynostosis over the observed study period. Perinatal conditions, feeding difficulties, nervous system anomalies, respiratory, and other infections contributed to majority of infant non-CS-related admissions.Respiratory infections accounted for about twice the number of admissions for individuals with CS (IRRs 1.94-2.34) across all observed age groups. Higher incidence of non-CS hospitalizations was observed among females, with associated anomalies, to families with highest socioeconomic disadvantage and living in remote areas of the state. Conclusion: Marginal reduction in the cLoS for CS-related admissions observed over the 21-year period are potentially indicative of improved peri-operative care. However, higher incidence of respiratory infection-related admissions for syndromic synostosis is concerning and requires investigation.

Abstract
BACKGROUND Endoscopic strip craniectomy with postoperative helmeting (ESCH) for unicoronal synostosis has shown to be a less morbid procedure when compared with fronto-orbital remodeling (FOR). We aim in this pilot study to report objective methods and quantitative morphologic outcomes of endoscopically treated unicoronal synostosis using 3-dimensional surface scans. METHODS Our electronic records were reviewed for ophthalmological, neurodevelopmental outcomes, and helmet-related complications. For morphologic outcomes, the following parameters were used: Cranial Index, Cranial Vault Asymmetry Index, Anterior Symmetry Ratio (ASR), and Root Mean Square between the normal and synostotic sides of the head. Three-dimensional stereophotogrammetry scans were evaluated at 3 time points preoperative, 6 months post-op, and at the end of the treatment, which was compared with age-matched scans of normal controls and FOR patients. Nonparametric tests were used for statistical analysis. RESULTS None of the ESCH cases developed strabismus, major neurodevelopmental delay, or helmet complications. All morphologic parameters improved significantly at 6 months post-op except for the Cranial Vault Asymmetry Index. The ASR was the only parameter to change significantly between 6 months post-op and final scans. At end of helmet treatment, ASR and Root Mean Square differed significantly between the ESCH and both FOR and control groups. CONCLUSIONS Endoscopic strip craniectomy with postoperative helmeting for single unicoronal synostosis had excellent clinical outcomes. Most of the improvement in head morphology occurred in the first 6 months of treatment. Despite the normalization of the overall head shape, there was residual asymmetry in the frontal and temporal regions of the head.

Abstract
OBJECTIVE Aesthetic assessment after surgery for non-syndromic single suture craniosynostosis (SSC) is crucial. Surgeons' evaluation is generally based on Whitaker classification, while parental impression is generally neglected. The aim of this paper is to compare aesthetic perceptions of parents and surgeons after surgery for SSC, expressed by a 10-item questionnaire that complement Whitaker's classification. METHODS The authors submitted a 10-item questionnaire integrating Whitaker's classification in order to evaluate the degree of satisfaction, the detailed aesthetics results and the need for surgical revision, to surgeons and parents of a consecutive series of patients operated for SSC between January 2007 and December 2018. The results were collected blindly. RESULTS A total of 70 patients were included in the study. Scaphocephaly and trigonocephaly were the two most frequent craniosynostosis. Parents and surgeons general aesthetics evaluation and average rating for Whitaker's classification were 1.86 vs 1.67 (p = 0.69) and 1.19 vs 1.1 (p = 0.45) respectively. Parents' evaluation for scar perception and alopecia (p < 0.00001), the presence of bony crest (0.002), bony bump (p < 0.00001), or other bone irregularities (p = 0.02) are significantly worse when compared to surgeons' perception. CONCLUSIONS Parents seem to be more sensitive to the detection of some aesthetic anomalies and their opinion should not be neglected. The authors propose a modified Whitaker classification based on their results to better stratify the aesthetic outcome after surgery for SSC.

Abstract
Background Sinus pericranii is a rare cranial venous malformation resulting in a subcutaneous mass due to abnormal communication between intracranial and subperiosteal/interperiosteal veins. To date, to the best of our knowledge, there are no reports of sinus pericranii associated with syntelencephaly, a subtype of lobar holoprosencephaly. We herein report a case of sinus pericranii associated with syntelencephaly. This report can provide us better understanding of the etiology of sinus pericranii, the potential risks, and the treatment options for these patients. Case presentation A 2-year-4-month old female patient who received the diagnosis of syntelencephaly as a neonate presented with a subcutaneous mass in the parietal region. The mass was soft, nonpulsatile, 3 × 2 cm in size, and showed enlargement in the lying position. Color cranial Doppler ultrasound, head magnetic resonance imaging (MRI), and cerebral angiography revealed a dilated vessel passing through the parietal bone and forming a communication between the superior sagittal sinus and scalp veins. Based on these findings, sinus pericranii was diagnosed. The head MRI also showed coronal craniosynostosis, a tight posterior fossa. At age 2 years and 7 months, the patient underwent a transection of the sinus pericranii and the mass resolved without any complications or recurrences for more than 2.5 years to date. Conclusion Sinus pericranii is a rare cranial and venous malformation sometimes accompanied by brain malformations or craniosynostosis that may become more apparent as the brain and skull develop. Since this condition can be complicated by intracranial hemorrhage and sinus thrombosis, early detection is necessary to determine the treatment options. Physicians should be alert to the possibility of this condition if they observe a soft cranial mass that appears to decrease in size in the sitting position and bulge in the lying position.

Abstract
The resurgence of strip craniectomies began in the mid-1990s with advances in surgical technique and anesthesia coupled with the critical observation that earlier interventions benefitted from an easily molded skull. Jimenez and Barone's pioneering introduction of endoscopic approaches to strip craniectomies coupled with postoperative helmeting in newborns and young infants and Claes Lauritzen's introduction of spring-mediated cranioplasty began the era of minimally invasive approaches in the surgical correction of craniosynostosis. This article provides technical descriptions of these treatment modalities, a comparative literature review, and our institutional algorithms for the correction of sagittal craniosynostosis and unilambdoid craniosynostosis.

Abstract
BACKGROUND European Reference Networks (ERNs) are networks involving hospitals with particular expertise in rare conditions. ERN-CRANIO focusses on rare disorders of the skull and face, including craniosynostosis. METHODS We undertook a pilot study in the form of an electronic survey to understand current practice in craniosynostosis management across ERN-CRANIO, which at the time consisted of 29 member institutions across 11 countries. 19/29 units replied, however some answered the survey only partially. RESULTS 87.5% of units have specific management protocols. For single suture cases 8/15 units see >50 new cases per year, 4/15 21-50 cases, and 3/15 <20 cases. Duration of follow up ranges from age 10 years or less (3/6) to indefinite (2/6). A variety of surgical techniques are used. For sagittal synostosis, endoscopic and helmet is the most common (5/14) and for metopic and unicoronal synostosis, preferred by 9/14 centres, was fronto-orbital remodelling (bandeau). For multisutural syndromic craniosynostosis 2/16 centres see >20 new cases per year, 4/16 11-20 cases, 5/16 6-10 cases, 4/16 <5 cases. Most centres (12/15) either never discharge syndromic patients or follow until adulthood. 11/14 units perform prophylactic vault expansion, whilst 3/14 wait for clinical indication. 9/13 units operate at 6-12 months. Again, a wide variety of techniques are used, most commonly frontal advancement (4/13) initially. CONCLUSION This study provides a useful snapshot of current standards of care in craniosynostosis across the high volume centres of the ERN. Going forward these results can be used to direct more detailed analysis of current practice which will then be useful for constructing a management guideline for patients presenting with both single suture and multisutural craniosynostosis.

Abstract
BACKGROUND The authors have developed pretrained machine learning (ML) models to evaluate neonatal head shape deformities using top-down and facial orthogonal photographs of the patient's head. In previous preliminary analysis, this approach was tested with images from an open-source data bank. OBJECTIVE To determine the accuracy of pretrained ML models in identifying craniosynostosis among patients seen in our outpatient neurosurgery clinic. METHODS We retrospectively reviewed top-down and facial orthogonal images of each patient's head and provider clinical diagnosis from the same encounters. Head shape classifications generated from 3 pretrained ML models (random forest, classification and regression tree, and linear discriminant analysis) were applied to each patient's photograph data set after craniometric extraction using a predefined image processing algorithm. Diagnoses were codified into a binary scheme of craniosynostosis vs noncraniosynostosis. Sensitivity, specificity, and Matthew correlation coefficient were calculated for software vs provider classifications. RESULTS A total of 174 patients seen for abnormal head shape between May 2020 and February 2021 were included in the analysis. One hundred seven patients (61%) were seen in-person and 67 (39%) through telemedicine. Twenty-three patients (13%) were diagnosed with craniosynostosis. The best-performing model identified craniosynostosis with an accuracy of 94.8% (95% CI 90.4-97.6), sensitivity of 87.0% (95% CI 66.4-97.2), specificity of 96.0% (95% CI 91.6-98.5), and Matthew correlation coefficient of 0.788 (95% CI 0.725-0.839). CONCLUSION Machine learning-driven image analysis represents a promising strategy for the identification of craniosynostosis in a real-world practice setting. This approach has potential to reduce the need for imaging and facilitate referral by primary care providers.

Whole-exome sequencing in syndromic craniosynostosis increases diagnostic yield and identifies candidate genes in osteogenic signaling pathways. Am J Med Genet A 2022; 188:1464-1475. [PMID: 35080095 DOI: 10.1002/ajmg.a.62663] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 11/26/2021] [Accepted: 12/26/2021] [Indexed: 11/07/2022]
Abstract
Craniosynostosis (CS) is a common congenital anomaly defined by premature fusion of one or more cranial sutures. Syndromic CS involves additional organ anomalies or neurocognitive deficits and accounts for 25%-30% of the cases. In a recent population-based study by our group, 84% of the syndromic CS cases had a genetically verified diagnosis after targeted analyses. A number of different genetic causes were detected, confirming that syndromic CS is highly heterogeneous. In this study, we performed whole-exome sequencing of 10 children and parents from the same cohort where previous genetic results were negative. We detected pathogenic, or likely pathogenic, variants in four additional genes (NFIA, EXTL3, POLR2A, and FOXP2) associated with rare conditions. In two of these (POLR2A and FOXP2), CS has not previously been reported. We further detected a rare predicted damaging variant in SH3BP4, which has not previously been related to human disease. All findings were clustered in genes involved in the pathways of osteogenesis and suture patency. We conclude that whole-exome sequencing expands the list of genes associated with syndromic CS, and provides new candidate genes in osteogenic signaling pathways.

The Dura Split Technique in the Treatment of Craniosynostosis: Is It Still an Option? J Craniofac Surg 2022; 33:1514-1516. [PMID: 34980837 DOI: 10.1097/scs.0000000000008449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Accepted: 11/25/2021] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND The aim of this study was to report the outcome and the complications for patients operated on for craniosynostosis using the dura split technique. Specifically, the authors aimed to evaluate the safety of this technique, which is currently not in use, and to determine whether it is still useable. METHODS The data was collected from the hospital patient records of all children surgically treated for craniosynostosis using the dura split technique in Turku University Hospital during the period 1975 to 2015. The data was analyzed to determine the clinical and radiological outcomes of the surgical procedure, the need for reoperations, and the rate of complications. RESULTS During the study period, the dura split technique was used in the surgery of 65 patients. The outcome was either good or acceptable in most patients and reoperation was needed in only 2 patients (3.1%). Surgical complications included significant blood loss (26.2%), lesions on the inner layer of the dura (21.5%), leakage of cerebrospinal fluid (13.8%), and persistent bone defects (15.4% on palpation and 63.1% radiologically). CONCLUSIONS Although the outcome of surgery for craniosynostosis using the dura split technique was mostly acceptable and the need for reoperations rare, the technique cannot, however, be recommended in the future due to high rates of bone defects, frequent problems with lesions on the inner layer of the dura, and consequent perioperative leakage of cerebrospinal fluid.

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

Quality of life and satisfaction in surgical versus conservative treatment of nonsyndromic children with craniosynostosis. J Neurosurg Pediatr 2022; 29:60-65.

Abstract
OBJECTIVE Craniosynostosis represents the second most common reason for referral to pediatric neurosurgery. However, the quality of life and neurodevelopmental impact of leaving this physical disorder uncorrected is poorly understood. METHODS This multicenter cross-sectional study identified previously managed nonsyndromic infants (< 24 months of age) with single-suture craniosynostosis at both pediatric neurosurgical centers in Alberta, Canada. The primary variable of interest was the allocated treatment (surgical vs conservative). The primary outcome was the Pediatric Quality of Life Inventory (PedsQL), a validated measure of quality of life examining physical, emotional, social, and school functioning. Treatment decision satisfaction and the reasons for selected management were quantified and collected directly from caregivers. RESULTS One hundred fourteen children met the inclusion criteria: 78% underwent surgery and 22% had conservative treatment. The most common suture affected was sagittal (54%), followed by metopic (33%), coronal (10%), and lambdoid (3%). Caregivers most commonly opted for surgery because of severe appearance (80%). Seventy-six percent and 72% of the caregivers of children with conservative management did so due to concerns of surgical risks and mild appearance, respectively. There was a statistically significant relationship between both the parents' (p < 0.001) and the surgeon's (p = 0.001) impression of a severe head shape and surgical management. Parental satisfaction with their child's appearance as well as satisfaction with their treatment decision did not differ between management types. Regarding quality of life, on univariate analysis, the conservative group had a statistically higher physical summary score (p = 0.01), psychosocial summary score (p = 0.004), and mean total scale score (p = 0.003) compared to the surgical group. However, after adjusting for severity and age at consult, no significant independent associations between management type and any of the PedsQL summary scores were found. CONCLUSIONS Alberta families have a high number of children with craniosynostosis treated with conservative management. Conservatively managed infants were largely minimally affected patients, particularly those with metopic synostosis. The study found no independent association between management type (surgery vs conservative) and quality of life when adjusted for important patient factors.

Abstract
OBJECTIVE Craniosynostosis is a congenital disorder resulting from the premature fusion of cranial sutures in the infant skull. This condition results in significant cosmetic deformity and can impede neurodevelopment, if left untreated. Currently, rates of craniometric change following minimally invasive surgery have only been examined for sagittal craniosynostosis. A better understanding of postoperative skull adaptations in other craniosynostosis subtypes is needed to objectively categorize surgical outcomes and guide length of cranial orthosis therapy. METHODS Eleven patients with sagittal and 8 with metopic craniosynostosis treated using endoscopic strip craniectomy and postoperative helmet orthoses were retrospectively reviewed. Using semiautomated image analysis of top-down orthogonal 2D photographs, the following craniometrics were recorded before surgery and at postoperative visits: cephalic index (CI), cranial vault asymmetry index (CVAI), anterior arc angle (AAA), posterior arc angle (PAA), anterior-middle width ratio (AMWR), anterior-posterior width ratio (APWR), left-right height ratio (LRHR), sagittal Hu moment (Sag-Hu), and brachycephaly Hu moment (Brachy-Hu). These craniometrics were then normalized to photograph-based measurements of normocephalic patients and the rates of change between metopic and sagittal craniosynostoses were compared. RESULTS Patients with sagittal craniosynostosis exhibited significantly lower CI, lower PAA, higher AMWR, higher APWR, lower Sag-Hu, and higher Brachy-Hu preoperatively compared to patients with normocephalic craniosynostosis. Patients with metopic craniosynostosis exhibited lower AAA and AMWR preoperatively compared to normocephalic subjects. Sagittal and metopic patients had a rapid initial change in normalized CI or AAA, respectively. Craniometric rates of change that significantly differed between metopic and sagittal patients were found in AAA (p < 0.001), AMWR (p < 0.001), and APWR (p < 0.0001). Metopic patients had a prolonged AAA change with a significantly different rate of change up to 6 months postoperatively (median at 3 months = 0.027 normalized units/day, median at 6 months = 0.017 normalized units/day, and median at > 6 months = 0.007 normalized units/day), while sagittal CI rate of change at these time points was not significantly different. CONCLUSIONS Patients with metopic craniosynostosis have a prolonged rate of change compared to patients with sagittal craniosynostosis and may benefit from longer helmet use and extended postoperative follow-up. Categorizing craniometric changes for other craniosynostosis subtypes will be important for evaluating current treatment guidelines.

Abstract
Costello syndrome (CS) is an autosomal dominant disorder caused by pathogenic variants in HRAS. Craniosynostosis is a known feature of other RASopathies (Noonan and cardiofaciocutaneous syndromes) but not CS. We describe four individuals with CS and craniosynostosis and present a summary of all previously reported individuals with craniosynostosis and RASopathy.

Abstract
In recent decades, cell biology has made rapid progress. Cell isolation and cultivation techniques, supported by modern laboratory procedures and experimental capabilities, provide a wide range of opportunities for in vitro research to study physiological and pathophysiological processes in health and disease. They can also be used very efficiently for the analysis of biomaterials. Before a new biomaterial is ready for implantation into tissues and widespread use in clinical practice, it must be extensively tested. Experimental cell models, which are a suitable testing ground and the first line of empirical exploration of new biomaterials, must contain suitable cells that form the basis of biomaterial testing. To isolate a stable and suitable cell culture, many steps are required. The first and one of the most important steps is the collection of donor tissue, usually during a surgical procedure. Thus, the collection is the foundation for the success of cell isolation. This article explains the sources and neurosurgical procedures for obtaining brain tissue samples for cell isolation techniques, which are essential for biomaterial testing procedures.

Abstract
ABSTRACT Minimally-invasive endoscopic-assisted craniectomy (EAC) achieves similar functional and cosmetic outcomes, whereas reducing morbidity risk that is often associated with complex cranial vault reconstruction. Antifibrinolytics (AF) usage to limit blood loss and transfusion requirements during complex cranial vault reconstruction has been studied extensively; however, studies are limited for AF therapy in EAC. The aim of this single-center retrospective observational cohort pilot study was to evaluate whether the use of AF was associated with reduced blood loss in infants undergoing EAC. The authors hypothesized that there would be no difference in blood loss between patients who received AF and those that did not receive AF during EAC. Non-syndromic patients who underwent single-suture EAC were retrospectively evaluated. Primary outcome measure was intraoperative calculated blood loss (mL/kg). Secondary outcome measures included perioperative red blood cells transfusion volumes, number of blood donor exposures, and pediatric intensive care unit and total hospital length of stay. Study cohort demographic and outcome data were analyzed; Fisher exact test was used for categorical data, Student t test was used for continuous data. A P value of < 0.05 was considered statistically significant. Forty-nine EAC patients were included in the study with 34 patients in the AF cohort and 15 patients in the non-AF cohort. There were no significant differences in demographics between the 2 groups. Additionally, there was no significant difference in intraoperative calculated blood loss or any secondary outcome measure. In our single-suture EAC study cohorts, AF administration was not associated with a decrease in blood loss when compared to those that did not receive AF therapy.

Abstract
BACKGROUND Scaphocephaly is the commonest from of craniosynostosis. There are several surgical methods to correct this and is influenced by the areas affected. A common thread in any of these corrections is an attempt to increase the biparietal diameter by modifying the lateral vault panel (LVP). A simple and novel method is proposed. MATERIALS AND METHOD The records of all patients undergoing scaphocephaly correction in the craniofacial unit at the institution were reviewed from 2003 to 2019. There were 106 patients, 57 males, and 49 females. The age ranged from 6 months to 5 years with a mean of 11 months. The method of vault remodeling was LVP only in 36 (34%), subtotal vault remodeling in 59 (56%), and total vault remodeling in 11 (10%). All 106 patients underwent LVP remodeling as part of the procedure. One or 2 wedge excisions was performed to increase the curvature of the LVP and this panel was fixed on the outside of the temporal squame bone. RESULTS The patients were followed up for a minimum of 1 year. Satisfactory results were obtained. The mean preoperative cephalic index was 64% and the mean postoperative index was 75%. There were minor complications such as screw visibility in a few patients. CONCLUSIONS Wedge excisions of the LVP is a simple and effective maneuver that can be used as strategy when performing scaphocephaly correction.

Abstract
BACKGROUND Craniosynostosis is a bony dysmorphism of the calvarium due to premature suture fusion and is classified as syndromic (part of congenital syndrome) or nonsyndromic (isolated). Deformational plagiocephaly (DP) is due to external positional forces on the skull after birth. This review aims to investigate the various quality of life (QoL) metrics across syndromic, nonsyndromic and DP patients. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a literature search was done through EMBASE, MEDLINE, PubMed and Web of Science. After two stages of screening by two authors, seventeen articles met inclusion criteria; 11 on syndromic, 4 nonsyndromic, and 2 DP. RESULTS The literature suggests syndromic patients have more severe consequences on QoL, especially on psychological well-being, social functioning, and obstructive sleep apnea (OSA), leading to behavioral difficulties. Nonsyndromic patients show a less clear trend across QoL measures, but a majority stated QoL is comparable to the general population. DP patients noted motor development and QoL improvement as well as improved subjective aesthetic outcomes after orthotic helmet molding therapy (HMT). CONCLUSIONS While a majority of literature classifies QoL in syndromic craniosynostosis alone, this review highlights the importance of these factors in nonsyndromic craniosynostosis and plagiocephaly patients. Psychological well-being, social functioning, and secondary health impacts such as OSA are important to consider in comprehensive craniofacial care in all calvaria deformities.

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.

Abstract
IMPORTANCE Findings on the cognitive, behavioral, and psychological functioning of individuals with sagittal synostosis (SS) are highly disparate, limiting their clinical utility. OBJECTIVE To identify and review research on individuals with SS and to determine whether, and to what extent, they experience cognitive, behavioral, and psychological difficulties compared with their healthy peers or normative data for each measure. DATA SOURCES PubMed, Scopus, Embase, and PsycINFO were searched through January 2021 with no date restrictions. Scopus citation searches and manual checks of the reference lists of included studies were conducted. STUDY SELECTION Studies included participants of any age who had received a diagnosis of single-suture (isolated or nonsyndromic) SS or scaphocephaly and who had been assessed on cognitive, behavioral, and psychological outcomes. DATA EXTRACTION AND SYNTHESIS Data were independently extracted by 2 reviewers. Case-control outcomes (individuals with SS vs healthy peers or normative data) were compared using random-effects models with 3 effect sizes calculated: weighted Hedges g (gw), odds ratios (ORs), and mean prevalence rates. This study follows the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines. MAIN OUTCOMES AND MEASURES Findings were categorized by surgical status (conservatively managed, presurgery, postsurgery, or combined); domain (eg, general cognition); type of cognitive, behavioral, or psychological measure (objective or subjective); and source of comparison data (peers or normative data). RESULTS Data from 32 studies, involving a pooled sample of 1422 children and adults with SS (mean [SD] age at assessment, 5.7 [6.6] years; median [interquartile range] age, 3.3 [0.5-10.3] years), were analyzed. Data on sex were available for 824 participants, and 642 (78%) were male. Individual study results varied substantially. Objective tests identified significant moderate group differences on 3 of 16 examined domains: presurgical motor functioning (3 studies; gw = -0.42; 95% CI, -0.67 to -0.18; P < .001), postsurgical short-term memory (2 studies; gw = -0.45; 95% CI, -0.72 to -0.17; P < .001), and postsurgical visuospatial ability (6 studies; gw = 0.31; 95% CI, 0.18 to 0.44; P < .001). Prevalence estimates and ORs varied widely, with 15 studies showing prevalence estimates ranging from 3% to 37%, and 3 studies showing ORs ranging from 0.31 (95% CI, 0.01 to 6.12) for processing speed in the conservatively managed sample to 4.55 (95% CI, 0.21 to 98.63) for postsurgical visuospatial abilities. CONCLUSIONS AND RELEVANCE In this meta-analysis, findings for the functioning of participants with SS were highly disparate and often of low quality, with small samples sizes and control groups rarely recruited. Nonetheless, the findings suggest that some individuals with SS experience negative outcomes, necessitating routine assessment.

Abstract
INTRODUCTION Although physicians from a variety of specialties encounter infants with possible craniosynostosis, judicious use of computed tomography (CT) imaging is important to avoid unnecessary radiation exposure and healthcare expense. The present study seeks to determine whether differences in specialty of ordering physician affects frequency of resulting diagnostic confirmations requiring operative intervention. METHODS Radiology databases from 2 institutions were queried for CT reports or indications that included "craniosynostosis" or "plagiocephaly." Patient demographics, specialty of ordering physician, confirmed diagnosis, and operative interventions were recorded. Cost analysis was performed using the fixed unit cost for a head CT to calculate the expense before 1 study led to operative intervention. RESULTS Three hundred eighty-two patients were included. 184 (48.2%) CT scans were ordered by craniofacial surgeons, 71 (18.6%) were ordered by neurosurgeons, and 127 (33.3%) were ordered by pediatricians. One hundred four (27.2%) patients received a diagnosis of craniosynostosis requiring operative intervention. Craniofacial surgeons and neurosurgeons were more likely than pediatricians to order CT scans that resulted in a diagnosis of craniosynostosis requiring operative intervention (P < 0.001), with no difference between craniofacial surgeons and neurosurgeons (P = 1.0). The estimated cost of obtaining an impact CT scan when ordered by neurosurgeons or craniofacial surgeons as compared to pediatricians was $2369.69 versus $13,493.75. CONCLUSIONS Clinicians who more frequently encounter craniosynostosis (craniofacial and neurosurgeons) had a higher likelihood of ordering CT images that resulted in a diagnosis of craniosynostosis requiring operative intervention. This study should prompt multi-disciplinary interventions aimed at improving evaluation of pretest probability before CT imaging.

Abstract
ABSTRACT In this retrospective study, the authors determined changes in intracranial volume (ICV) and cephalic index (CI) in patients with sagittal craniosynostosis and operated with craniotomy combined with either 2 or 3 springs. The authors included patients (n = 112) with complete follow-up that had undergone surgical correction for isolated sagittal craniosynostosis with craniotomy combined with springs between 2008 and 2017. All patients underwent computed tomography examination preoperative, at the time of spring extraction, and at 3 years of age. Intracranial volume was measured using a semiautomatic MATLAB program, and CI was calculated as the width/length of the skull. The authors found that craniotomy combined with 2 springs increased the ICV from a preoperative value of 792 ± 113 mL (mean ± standard deviation) to 1298 ± 181 mL at 3 years of age and increased the CI from 72.1 ± 4.1 to 74.6 ± 4.3, whereas craniotomy combined with 3 springs increased the ICV from 779 ± 128 mL to 1283 ± 136 mL and the CI from 70.7 ± 4.3 to 74.8 ± 3.7. The relative increase in ICV was 65 ± 21% in the two-spring group and 68 ± 34% in the three-spring group (P value = 0.559), and the relative increase in CI was 3.6 ± 3.3% in the two-spring group as compared with 6.0 ± 5.0% in the three-spring group (P = 0.004). These findings demonstrated that use of 3 springs resulted in additional absolute and relative CI-specific effects as compared with 2 springs during the time when the springs were in place, with this effect maintained at 3 years of age.

The role of pulsatile and static intracranial pressure measurements in the management of children with craniosynostosis-an institutional experience from 49 patients. Acta Neurochir (Wien) 2021; 163:2015-2023. [PMID: 33389123 DOI: 10.1007/s00701-020-04680-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Accepted: 12/14/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND Although measurement of intracranial pressure (ICP) has occasionally been utilized in children with craniosynostosis (CSS), data on parameters of pulsatile ICP in CSS are still lacking, and the role of pulsatile ICP measurements in the management of CSS is not well established. METHODS From our department's database, we retrieved the data from children in whom the measurement of static and pulsatile ICP was a part of the diagnostic work-up in different clinical situations related to CSS. Both clinical and ICP data were retrospectively reviewed and analyzed. RESULTS We identified 49 children with CSS, median age 4.4 years (range 0.2-18.9), in whom a total of 67 diagnostic ICP measurements were undertaken between 2002 and 2014. The CSS was syndromal in 23 cases. The rationale for ICP measurement was a question of indication for cranial vault expansion surgery (CVES) in 12 patients (Group 1), of its timing in 10 patients (Group 2), of suspected abnormally elevated ICP or hydrocephalus in 11 patients (Group 3), of indication for repeated CVES in 13 patients (Group 4), or shunt dysfunction in three patients (Group 5). The average mean ICP for the whole cohort was 15.1 ± 5.5 mmHg and mean wave amplitude (MWA) 5.3 ± 2.2 mmHg. There was no significant difference in ICP parameters when compared between Groups 1-5. Fundoscopy revealed papilledema in five out of 32 children (15.6%). There were significantly higher parameters of pulsatile ICP (MWA) in patients with papilledema, but no statistically significant difference in parameters of static ICP. CONCLUSIONS In this cohort of pediatric patients with CSS presenting with various diagnostic challenges, we found the diagnostic measurement of static and pulsatile ICP useful in selecting the optimal treatment modality and timing of surgery. Papilledema was associated with elevated pulsatile ICP, a parameter that in previous studies has been shown to correlate with impaired intracranial compliance.

Abstract
Endoscopic suturectomy combined with supplementary techniques such as spring-assisted expansion and cranial molding helmets for the correction of craniosynostosis is growing in popularity due to the reduced scar burdened, decreased morbidity, and reduced overall cost. The authors present their technique for the correction of isolated coronal craniosynostosis. The use of dedicated endoscopic tools and lit endoscopes permits enhanced visualization and technical ability, particularly at the distal portions of the suturectomy, and may reduce operative time and cerebrospinal fluid leak risk.

Abstract
ABSTRACT Sagittal craniosynostosis results in scaphocephaly from abnormal fusion of the sagittal suture. Traditionally, craniosynostosis presents at birth and is diagnosed within the first year of life. We report a patient with development of sagittal craniosynostosis after birth, which we term postnatal sagittal craniosynostosis (PSC). This is a rare occurrence in which management considerations are critical but are not well discussed. A 3-year old boy presented with concerns of a metopic ridge. Work-up revealed metopic ridging and an open sagittal suture. The patient later developed signs of increased intracranial pressure (ICP) and repeat CT scan 14 months later identified a newly fused sagittal suture. The patient underwent open posterior cranial vault expansion, resulting in resolution of symptoms. PSC is a rare condition and should be considered in otherwise unexplained increases in ICP among pediatric patients. Open posterior cranial vault expansion represents a safe and effective method to treat this condition.

Abstract
The cause of occipital asymmtery can be either extrinsic or intrinsic. Intrinsic causes include lambdoid craniosynsotosis. This condition is generally treated with cranial vault expansion surgery. Extrinsic causes include deformational plagiocephaly, which became commonplace after the "Back to Sleep Campaign" instituted in the 1980s by the American Academy of Pediatrics. The treatment of this condition is non surgical. Dr. Joseph Gruss was instumental in differentiating between these conditions and reducing the number of unnecessary surgeries that were previously being performed.
