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
OBJECTIVE To correlate the magnitude of the amount of translation of prosthesis and the native joint, and the postoperative change in the volume of the contralateral condylar process after unilateral total joint replacement. MATERIAL AND METHODS The study examined 16 patients with post-traumatic jaw deformation treated with unilateral TMJ replacement using total endoprosthesis. The mandible kinematics was recorded using the Cadiax Diagnostic system and correlated with the remodeling of the native joint. RESULT On average, the group showed an 8.5% decrease in the volume of the native condylar process. In 13 patients, the amplitude of the native joint movement in the mouth opening and the mandible pro- and laterotrusion markedly deviated quantitatively that combined with the translational movement of the TMJ endoprosthesis in all types of mandibular abduction in all the patients. Correlation analysis showed a moderate negative relationship (r= -0.43) in opening the mouth between the amplitude of movement of the native joint and of the endoprosthesis, as well as a noticeable negative strength of relationship. Also, the correlation analysis showed a moderate positive relationship between the change in the native condylar process volume and movement amplitude when opening the mouth, and an inverse correlation of the high strength of relationship between the change in the native condylar process volume and movement amplitude of the TMJ endoprosthesis. CONCLUSION Electronic axiography found that patients in the postoperative period could restore some of the translational movements even with the attachment of the lateral pterygoid muscle cut off. The main factor influencing the magnitude of the endoprosthesis translational movement is the design of the fossa component: the ratio of the circumferential surface of the fossa to the diameter of the head of the endoprosthesis, as well as the presence of lateral stoppers. The study showed that unilateral TMJ reconstruction provides changes in the volume of the native joint directly related to the amplitude of the movement of the joint itself and inversely correlated with the amplitude of the movement of the endoprosthesis.

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
ABSTRACT Craniosynostosis (CSS), the premature fusion of calvarial sutures, most commonly involves the sagittal suture. Cranial vault remodeling (CVR) is a traditional method of CSS correction. Minimally invasive methods are becoming widely accepted, including spring-assisted surgery (SAS). The equipment required for SAS is minimal therefore adaptable to resource challenged health systems. This paper outlines the experience of SAS in Moldova.A retrospective study was performed for patients treated with SAS for sagittal CSS from 2011 to 2018 in Moldova. Perioperative data were recorded including age, length of surgery, blood loss, volume transfused and length of stay. Four patients had pre- and post-operative computed tomography (CT) scans which were used to calculate changes in cephalic index, normative cephalic index, and intracranial volume.Thirteen patients underwent SAS. Diagnoses were made clinically and confirmed with CT. Mean age at surgery was 4.0 months, and length of surgery 62.7 minutes. All but one patient received a blood transfusion, as is standard of practice in Moldova. The mean length of post-operative recovery in ICU was 30.9 hours. No complications required surgical revision. Springs were removed after 4 to 5 months. All patients had a subjective improvement in scaphocephaly. Based on the available CT scans, an increase in cephalic index (7.3%), normative cephalic index (11.8%), and intracranial volume (38.1%) was observed. One patient underwent SAS at 11 months and required cranioplasty for asymmetry at the time of spring removal.SAS is a safe and cost-effective method of CSS correction that can be utilized in countries with limited health system resources.

Abstract
OBJECTIVE To study the effect of total cranial reconstruction for sagittal synostosis (scaphocephaly) deformity in Chinese children. METHODS A retrospective analysis was performed involving 23 children with isolated non-syndromic sagittal synostosis who were treated by total calvarial vault remodeling after 1 year of age from May 2015 to June 2019 in the Department of Neurosurgery, Children's Hospital of Nanjing Medical University. The authors reconstruct patients' pre- and post-operative cranial thin-section CT scan images and those of the control group. The cephalic index (traditional, normative), intracranial volume, horizontal point of maximum width (H-PMW), vertical point of maximum width (V-PMW), frontal to head height ratio and occipital to head height ratio data were analyzed using a paired t test or Wilcoxon signed-rank test. RESULTS Twenty-three patients met the inclusion criteria, including 19 males and 4 females. The ratio of males to females was 4.7:1. All patients underwent total cranial reconstruction. The average age was 26.52 months (13-48 months), the average operation time was 214.13 minutes (150-265 minutes), and the average amount of suspended erythrocytes was 200 ml (100-400 ml). The cranial morphology of all patients improved significantly after the operation. The traditional cephalic index (pre-operative: 0.70 (0.04); post-operative: 0.78 (0.02)) and normative cephalic index (pre-operative: 0.68 (0.03); post-operative: 0.77 (0.02)) were significantly increased (P < 0.0001). The mean horizontal point of maximum width improved from 0.54 to 0.56 (P = 0.0043), the mean vertical point of maximum width decreased from 0.59 to 0.54 (P = 0.0006), the frontal height decreased from 0.89 to 0.77 (P < 0.0001), and the occipital height improved from 0.78 to 0.88 (P < 0.0001). The intracranial volume increased from 1287.35 to 1426.90 cm3 (P < 0.0001). All of the children had a good skull shape and no recurrence of deformity. CONCLUSIONS Total calvarial reconstruction can effectively correct scaphocephaly in Chinese children, expand cranial volume, reduce cranial height, shorten fronto-occipital diameters and enlarge biparietal diameters.

Abstract
PURPOSE The aim of this study was to compare the outcome of intracranial volume (ICV) and cephalic index (CI) between two different techniques for surgical therapy of sagittal synostosis. MATERIAL AND METHODS Between 2011 and 2015, all patients scheduled for surgical therapy of sagittal synostosis were consecutively enrolled. All patients younger than 6 months underwent early extended strip craniectomy (ESC group), and patients older than 6 months underwent late modified pi-procedure (MPP group). To measure ICV and CI, data acquisition was performed via three-dimensional photogrammetry, 1 day before (T0) and between 10 and 12 weeks after surgery (T1). Results were compared with an age-matched reference group of healthy children. Perioperative parameters, as duration of surgery and the amount of blood loss of both surgical procedures were analyzed. RESULTS A total of 85 patients were enrolled. Of the patients, 48 underwent an extended strip craniotomy with parietal osteotomies and biparietal widening and 37 patients underwent a late modified pi-procedure. There was no significant difference between the ESC group and the MPP group regarding the efficacy of improving CI (p > 0.05). Both techniques were able to normalize CI and to improve head shape. ICV was normal compared to age-matched norm-groups with both techniques, pre- and postoperatively. However, duration of the surgical procedure and calculated blood loss were significantly lower in the ESC group (p < 0.05). CONCLUSION ESC and MPP were effective techniques to normalize cephalic index (CI) and improve head shape at their recommended time of surgery. Measurement of ICV and CI with 3D photogrammetry is a valid method to objectively evaluate patients before and after surgery without exposing pediatric patients to ionizing radiation.

Abstract
AIM Isolated sagittal synostosis is the commonest form of craniosynostosis. The reasons for surgery are to normalize the head shape and to increase the cranial volume, thus reducing the risk of raised intracranial pressure and allowing for normal brain development. It has been suggested that sagittal synostosis may impair neuropsychological development. This systematic review appraised the literature on the management of sagittal synostosis. METHODS A literature search was performed with the assistance of a professional librarian. Studies selected had to satisfy the criteria set by PICO (patients, intervention, comparison, and outcome). Cranial index and neuropsychological outcome were used as outcome measures. MINORS was used to assess the methodological quality of the selected articles. A score of 75% was deemed to be of satisfactory quality, and the quality of the evidence from the selected studies was graded using the GRADE system. RESULTS One hundred forty-eight articles were initially identified. Only 6 articles fulfilled the PICO criteria and scored a minimum of 75% on MINORS. Four studies compared 1 technique to another with documented cranial indices. Two studies compared 1 group to another and assessed the neuropsychological development. According to GRADE, the quality of evidence was deemed to be very low. CONCLUSIONS This systematic review assessed cranial index and neuropsychological outcome following surgery for isolated, nonsyndromic sagittal synostosis. The quality of the evidence in the published literature was noted to be of very low quality. There is a need for better-designed, prospective studies to guide surgeons involved in management of sagittal synostosis.

Abstract
BACKGROUND Single-suture craniosynostosis (SSC) results in head shape anomalies that likely affect social perceptions of appearance. The purpose of this study was to evaluate laypersons' ratings of attractiveness in children with and without SSC. Among cases, we also examined differences by suture fused and age at surgery. METHODS We collected photographs of 196 children with SSC and 186 children without SSC as infants (before surgery, for cases) and at ages 18 and 36 months. Photographs were rated by 8 raters, who were blinded to the population being studied. We used linear regression to compare appearance ratings for the 2 groups at each visit and to evaluate changes over time. Regression analyses were used to examine the association between age at surgery and appearance ratings. RESULTS Children with SSC received lower appearance ratings than unaffected controls at each visit (all P < 0.001). Appearance ratings decreased over time, with a similar trajectory for children with and without SSC. Among cases, those with unicoronal and lambdoid synostosis had the lowest ratings and those with sagittal synostosis had the highest. Age at surgery was inversely associated with appearance ratings. CONCLUSIONS Children with SSC received lower appearance ratings than unaffected controls, with minimal change after surgery. Better outcomes were associated with earlier surgery. These findings do not indicate that children with SSC failed to benefit from surgery, as without surgical intervention, asymmetrical head shape would likely have worsened over time. However, our data suggest that appearance does not fully "normalize."

Cephalic index correlates poorly with intracranial volume in non-syndromic scaphocephalic patients. Childs Nerv Syst 2014; 30:2097-102. [PMID: 24965681 DOI: 10.1007/s00381-014-2456-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2014] [Accepted: 05/23/2014] [Indexed: 10/25/2022]
Abstract
OBJECTIVES This study aims to compare pre- and postoperative cephalic indexes (CI) with corresponding segmented intracranial volumes (SIV) obtained from volumetric CT in scaphocephalic patients. METHODS Twenty-four patients (17 boys) who had undergone cranial vault remodeling due to scaphocephaly were compared from 3D-CT imaging datasets. The mean age of the patients at preoperative CT imaging was 5.5 months, and that at 1-year postoperative imaging, 21.5 months. The mean interval between preoperative CT imaging and surgery was 3.3 months. Pearson's correlation was used to test the correlation of both pre- and postoperative CI with SIV. A paired t test was used to compare differences in the pre- and postoperative mean values of CI and SIV. RESULTS AND DISCUSSION CI correlated poorly with intracranial volume both preoperatively (r = 0.274) and postoperatively (r = 0.128). The mean preoperative CI was 65.92 (range 57.99-73.97), and the mean postoperative, CI 70.24 (range 60.23-75.57). The mean preoperative intracranial volume was 877.79 cm(3) (range 638-1,256), and the 1-year postoperative volume, 1,249.04 cm(3) (range 1,039-1,529). The mean values of both CI and SIV increased significantly after surgery. In one patient, the CI in postoperative measurements was smaller, whereas in all patients, the postoperative SIV was larger than the preoperative intracranial volume. The mean percentage increase in CI was 6.6 %, whereas the mean increase in SIV was 43.1 %. CONCLUSION Cephalic index correlates poorly with intracranial volume in non-syndromic scaphocephalic patients. For some patients, surgery and growth resulted in only subtle or no change in CI despite a notable increase in intracranial volume.
