Abstract
OBJECTIVE The purpose of this study was to evaluate the surgical complications of patients treated for nonsyndromic sagittal craniosynostosis and the necessity for reoperations due to craniocerebral disproportion. MATERIALS AND METHODS The patient cohort of this study consisted of patients (N = 82) who were treated in the Oulu University Hospital using the open vault cranioplasty with a modified H-technique between the years 2008 to 2022. There were 69 males (84.1%) and 13 females (15.9%). The mean age at the primary operation was 6.1 months. Mean follow-up time was 9.0 years. RESULTS There were no major complications related to the procedures. Two patients (2.4%) had a minor dural lesion. There were no postoperative wound infections. Of the 82 patients, seven patients with primary craniosynostosis (13.0%) developed symptomatic craniocerebral disproportion requiring reoperation to increase intracranial volume. In all these patients, invasive intracranial pressure (ICP) monitoring was performed prior to decision-making. In the majority of cases, the aesthetical outcome was considered good or excellent. CONCLUSION The operative method used was feasible and safe. Thirteen percent of patients who were followed over 5 years required major surgery due to development of craniocerebral disproportion later in life.

Spazzapan P, Velnar T. Isolated Sagittal Craniosynostosis: A Comprehensive Review. Diagnostics (Basel) 2024; 14:435. [PMID: 38396475 PMCID: PMC10887665 DOI: 10.3390/diagnostics14040435] [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: 01/02/2024] [Revised: 02/08/2024] [Accepted: 02/13/2024] [Indexed: 02/25/2024] Open
Abstract
Sagittal craniosynostosis, a rare but fascinating craniofacial anomaly, presents a unique challenge for both diagnosis and treatment. This condition involves premature fusion of the sagittal suture, which alters the normal growth pattern of the skull and can affect neurological development. Sagittal craniosynostosis is characterised by a pronounced head shape, often referred to as scaphocephaly. Asymmetry of the face and head, protrusion of the fontanel, and increased intracranial pressure are common clinical manifestations. Early recognition of these features is crucial for early intervention, and understanding the aetiology is, therefore, essential. Although the exact cause remains unclear, genetic factors are thought to play an important role. Mutations in genes such as FGFR2 and FGFR3, which disrupt the normal development of the skull, are suspected. Environmental factors and various insults during pregnancy can also contribute to the occurrence of the disease. An accurate diagnosis is crucial for treatment. Imaging studies such as ultrasound, computed tomography, magnetic resonance imaging, and three-dimensional reconstructions play a crucial role in visualising the prematurely fused sagittal suture. Clinicians also rely on a physical examination and medical history to confirm the diagnosis. Early detection allows for quick intervention and better treatment outcomes. The treatment of sagittal craniosynostosis requires a multidisciplinary approach that includes neurosurgery, craniofacial surgery, and paediatric care. Traditional treatment consists of an open reconstruction of the cranial vault, where the fused suture is surgically released to allow normal growth of the skull. However, advances in minimally invasive techniques, such as endoscopic strip craniectomy, are becoming increasingly popular due to their lower morbidity and shorter recovery times. This review aims to provide a comprehensive overview of sagittal craniosynostosis, highlighting the aetiology, clinical presentation, diagnostic methods, and current treatment options.

[PMID: 37606834 PMCID: PMC10837263 DOI: 10.1007/s00381-023-06115-8] [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: 06/08/2023] [Accepted: 08/01/2023] [Indexed: 08/23/2023]
Abstract
PURPOSE The aim of the study was to compare the results of two surgical techniques for the treatment of isolated sagittal synostosis (ISS) by means of 3D stereophotogrammetry. One technique, the Renier's "H" technique (RHT) comprised a biparietal expansion, the other, the total vault remodeling (TVR) included also a frontal remodeling. METHODS The two groups of operated children were compared with a third control group of normocephalic children. The 3D scanning was performed in all children between 12 and 245 months of age. On each 3D image six measurements and indices have been made, with the aim of evaluating not only length and width of the head, but also the height. The cranial index (CI) was measured in a plane parallel to the nasion-tragus plane, at the intersection with the opisthocranion. RESULTS Each of the three groups (RHT, TVR, control group) included 28 children. The measurements that were influenced by the correction of the frontal bossing, namely the CI and the sagittal length, were closer to normocephaly after TVR than after RHT. Lesser or no statistical difference was documented in the measurements evaluating the biparietal aspect and the height of the vertex, indicating that the biparietal expansion is effective in both procedures. CONCLUSION Based on our results TVR results in a better esthetical outcome, particularly in relation to the direct surgical remodeling of the frontal bossing.

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
Scaphocephaly (SC) is defined as an elongation of the anteroposterior axis of the skull resulting from the abnormal fusion of the sagittal suture. This study describes the "Peau d'ours" technique and results for correcting SC. We conducted a consecutive and retrospective analysis of patients treated from 2011 to 2016. We evaluated the gender, age, and surgical outcomes. A total of 53 patients were enrolled with a mean age of 19 months old. The advantages of this technique are healthy coronal and lambdoid suture preservation and symmetrical parietal bone flap opening. This technique is safe and simple to reproduce, allowing good surgical outcomes with a low incidence of secondary craniosynostosis. This technique is ideal for patients older than six months old.

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
Craniosynostosis is the premature fusion of one or more sutures across the calvaria, resulting in morphological and health complications that require invasive corrective surgery. Finite element (FE) method is a powerful tool that can aid with preoperative planning and post-operative predictions of craniosynostosis outcomes. However, input factors can influence the prediction of skull growth and the pressure on the growing brain using this approach. Therefore, the aim of this study was to carry out a series of sensitivity studies to understand the effect of various input parameters on predicting the skull morphology of a sagittal synostosis patient post-operatively. Preoperative CT images of a 4-month old patient were used to develop a 3D model of the skull, in which calvarial bones, sutures, cerebrospinal fluid (CSF), and brain were segmented. Calvarial reconstructive surgery was virtually modeled and two intracranial content scenarios labeled “CSF present” and “CSF absent,” were then developed. FE method was used to predict the calvarial morphology up to 76 months of age with intracranial volume-bone contact parameters being established across the models. Sensitivity tests with regards to the choice of material properties, methods of simulating bone formation and the rate of bone formation across the sutures were undertaken. Results were compared to the in vivo data from the same patient. Sensitivity tests to the choice of various material properties highlighted that the defined elastic modulus for the craniotomies appears to have the greatest influence on the predicted overall skull morphology. The bone formation modeling approach across the sutures/craniotomies had a considerable impact on the level of contact pressure across the brain with minimum impact on the overall predicated morphology of the skull. Including the effect of CSF (based on the approach adopted here) displayed only a slight reduction in brain pressure outcomes. The sensitivity tests performed in this study set the foundation for future comparative studies using FE method to compare outcomes of different reconstruction techniques for the management of craniosynostosis.

Abstract
BACKGROUND Neurosurgical training usually requires long hours for hands-on procedures, making it difficult for inexperienced surgeons to quickly learn in an error-proof environment. The objective of this study was to propose a puzzle-like new model for neurosurgical education that simulates craniosynostosis correction (scaphocephaly type) using Renier's H technique. A model of a 3-dimensional (3D) anatomic simulator for craniosynostosis training is presented and evaluated. METHODS The cranial model was created using 1-mm computed tomography scan images from patients with scaphocephaly in the Digital Imaging and Communications in Medicine format. This information was processed using an algorithm to generate a 3D biomodel in resin. The puzzle model and its variable training models were assessed qualitatively by a team of expert neurosurgeons. Next, the model was applied in trainees and was evaluated using specific questionnaires. RESULTS Experts and trainees evaluated the model. The mean number of attempts without errors was 2.3 ± 0.675, for 1 error was 2.2 ± 0.918, and for 2 errors was 1.3 ± 0.707. The mean score of the simulator was 9.2 ± 0.421. Twelve residents (second evaluation) answered the questionnaire with a positive assessment of diagnosis capabilities, appropriateness of the model, time commitment, adequate environment, reliable 3D reconstruction, and teaching method. Three participants had used a 3D simulator previously, and the simulator was evaluated obtaining a 9.9 final average (range, 0-10). CONCLUSIONS The puzzle may be a complementary tool for surgical training. It allows several degrees of immersion and realism, offering symbolic, geometric, and dynamic information with 3D visualization. It provides additional data to support the practice of complex surgical procedures without exposing real patients to undue risk.

Abstract
There is currently no consensus on the surgical attitude to be adopted for late management of sagittal synostosis or for revision scaphocephaly surgeries without prolapse of the cerebellar tonsils. We present here a monocentric retrospective study of nine patients operated consecutively by a fixed expansion method of the cranial vault which may be associated with a fronto-orbital remodeling. The procedure consists in the realization of multiple parietal tongue-in-groove osteotomies fixed by resorbable plates. Simultaneous fronto-orbital remodeling have been performed when needed. No intraoperative complication was noted. The average operating time was 141min. Six patients (66.7%) had a blood transfusion during the perioperative period. The average hospital stay was 4.8days. With a mean follow-up of 26,7months, no surgical revision was noted. In all patients with clinical or ophthalmologic signs of intracranial hypertension, we highlighted a disappearance of signs within 4months. No protective helmet has been used. The craniofacial remodeling was judged very good by the family and the surgical team. Multiple tongue-in-groove tenons remolding cranioplasty associated or not with a fronto-orbital advancement is a safe technique. It seems to us to be a good alternative to floating or fixed bi-parietal or bi-parieto-frontal cranial flaps because of the very large increase in endocranial volume and the possibility of physiologically and aesthetically remodeling the parietal and fronto-orbital regions.

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

Abstract
Background Infants with sagittal suture synostosis often present a pathologic dilatation of subarachnoid spaces. The impact of such subarachnoid spaces' enlargement in the morphology of the skull, especially on the forehead and on the surgical outcome, was analyzed. Methods Children less than 6 months of age undergoing a surgical correction of the scaphocephaly with Renier's H technique between 2003 and 2008 were included in the study. In these patients, preoperative and postoperative fronto-occipital diameter (FOD), biparietal diameter (BPD), temporal width (TW), and naso-frontal angle (NFA) were measured. Cranial index (CI) and the difference between preoperative and postoperative CI (ΔCI) were calculated. Preoperative cranio-cortical width (CCW) was measured to analyze the subarachnoid spaces' volumes. The children here considered were then divided into two groups: Group 1 with CCW within normal estimated value corrected for age and Group 2 with CCW larger than estimated normal value. Results About 159 children were enrolled (72.3% male). CCW was larger than expected in 95 children (59.8%). A positive correlation between CCW and BPD (P ≤ 0.001) and a negative correlation between CCW and NFA (P ≤ 0.001) were found. When comparing the two groups, the mean age at preoperative computed tomography (CT) scan was 121 days in Group 1 and 110 days in Group 2. The mean age at operation was 130 days in Group 1 and 123 in Group 2. The mean age at postoperative examination (RX or CT scan) was 53.4 months in Group 1 and 51.8 months in Group 2. Preoperatively, the mean BPD, TW, and CI were significantly larger in Group 2 (P ≤ 0.01), whereas the NFA was significantly narrower (P = 0.03). Postoperative analysis showed that ΔCI was statistically different between the two groups (Group 1: 10%, Group 2: 7%; P < 0.04). The duration of follow-up period ranged between 19 and 129 months. Conclusion Two main subtypes of forehead of infants with scaphocephaly may be distinguished. Indeed, the morphology of the forehead differs when a pathologic subarachnoid spaces' enlargement is present preoperatively and it also affects the postoperative evolution. Such observation highlights the importance of evaluating whether subarachnoid spaces are enlarged when planning a surgical correction in isolated sagittal suture synostosis.

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
BACKGROUND Surgical correction for craniosynostosis is often associated with significant perioperative hemorrhage. We implemented a transfusion strategy with a strict protocol including transfusion triggers, frequent assessment of coagulation tests, and the use of a novel transfusion unit, the mixed pediatric unit. AIM The aim of the study was to evaluate if the applied transfusion strategy could reduce total blood loss and number of blood donors. METHODS Children <1 year old admitted for craniosynostosis surgery were included for the study. On the day before surgery, an adult red blood cell unit was mixed with plasma and split into two mixed pediatric units-one intended for intraoperative use and the other saved for the postoperative period. A series of blood samples were obtained for standard coagulation parameters as well as thromboelastography to evaluate potential coagulopathy. Estimated blood loss, the number of additional standard packed red cell units opened in the first 24 h after surgery, the volume of fluid administered, and the total transfusion volumes were compared to a historical control group with similar age and characteristics. RESULTS Nineteen infants were included in the study group, and were compared to 21 historical controls. There was a significant reduction of intraoperative transfusion volume. Twelve patients were transfused postoperatively, but in 8 of these additional exposure to packed red cell donor blood was avoided by using the saved mixed pediatric unit. In the historical controls, a total of 10 packed red cell units were used in nine patients postoperatively. No additional transfusions of plasma, platelets, fibrinogen, or tranexamic acid were needed in either group, and the coagulation parameters including thromboelastography remained within their respective normal ranges in the study group. CONCLUSION For craniofacial surgery in infants, moderate perioperative blood loss and avoidance of coagulopathy is possible when a multifactorial approach is implemented. In this setting, intraoperative, but not total perioperative blood loss was reduced with the studied protocol. The study indicates that there may be a role for mixed pediatric units to reduce exposure to multiple donors although the reduction in total donor exposure was not significant.

Abstract
PURPOSE The premature fusion of the sagittal suture (scaphocephaly) may be associated with intracranial cerebrospinal fluid (CSF) dynamics alterations resulting in pericerebral effusion (PE) and/or ventriculomegaly. However, the etiology and development of such collections are not fully elucidated. The aims of this study are to clarify the characteristics of intracranial CSF collection in scaphocephaly, consider the role of surgery, and analyze the prognostic factor on CSF dynamics. METHOD The pre- and postoperative cerebral imaging of 63 children (48 boys, 15 girls) with scaphocephaly who underwent craniotomy with decompression of the superior sagittal sinus (SSS) before 6 months of age between 2008 and 2015 were retrospectively studied. The PE was compared to the estimated value corrected for age (normal control). Evans' index (EI) was calculated. Correlations among these values and indices were analyzed. RESULT Preoperatively, 36 of 63 patients (57 %) had larger PE than expected, and 36 of 63 patients (57 %) had pathological EI (EI > 0.3), and among them, 26 (46 %) had both. Patients with large PE tended to have pathological EI (p = 0.005). The PE and the EI were significantly decreased postoperatively (p < 0.001). The PE decreased faster than the expected natural course in 59 of 63 patients (92 %) postoperatively. CONCLUSION The precise comparison with estimated PE prevalence corrected for age showed that PE can be found in more than half of the children with scaphocephaly, associated with ventriculomegaly. Surgery has a significant efficacious role in decreasing those CSF collections. The long-term significance of such CSF collections in scaphocephaly is still to be elucidated.

Abstract
OBJECT The aim of this study was to determine the distribution of Full Scale IQ (FSIQ) by type of craniosynostosis and to verify the finding that at long-term follow-up, verbal IQ (VIQ) is significantly higher than performance IQ (PIQ) in patients with single-suture sagittal synostosis (SS) despite falling within the "average" range for intelligence. Whether this also occurs in other types of craniosynostosis and whether surgery and sex are relevant were also determined. The relationship between age at time of surgery and later IQ was ascertained. METHODS The data for 91 children with craniosynostosis (47 sagittal, 15 unicoronal, 13 metopic, 9 multisuture, and 7 bicoronal) were collected at their routine, 10 years of age IQ assessment (mean age 123.8 months). The patients included 61 males and 30 females; 62 patients had undergone surgery and 29 had not. RESULTS The mean FSIQ for all types of craniosynostosis combined (96.2) fell within the average range for the general population. Some variation was evident across the different types of craniosynostosis: the SS group showed the highest FSIQs and a "normal" distribution of bandings; the other types had a higher proportion of FSIQs in the lower bandings. The data confirmed the finding that VIQ is greater than PIQ despite falling within the average range for intelligence, with a difference of 5.0 for all types of craniosynostosis combined (p = 0.001), 7.6 for the SS group (p = 0.001), and 6.9 for the unicoronal group (p = 0.029). This VIQ > PIQ effect was not found with multisuture craniosynostosis. The VIQ > PIQ discrepancy occurred regardless of whether the patient had undergone surgery and occurred more often in males than females. In the SS group and the bicoronal group, FSIQ (p = 0.036 and p = 0.046, respectively) and PIQ (p = 0.012 and p = 0.017, respectively), though not VIQ, were higher when surgery had been performed early. CONCLUSIONS The study confirms that at long-term follow-up, although children with nonsyndromic craniosynostosis fall within the normal range for intelligence, there is a VIQ > PIQ discrepancy above what would be expected in the normal population, which may be indicative of more subtle difficulties in achievement. This discrepancy is affected by type of craniosynostosis, sex, and age at time of surgery.

Abstract
Scaphocephaly is the most common single suture craniosynostosis. Surgical technique has evolved from simple strip craniectomy over π-procedures and vertex craniectomies to extensive cranial remodeling which is preferred procedure nowadays. The purpose of this paper is to present our modification of Renier's standard "H" technique and its preliminary results in detail. Eleven patients with scaphocephaly were surgically treated from January 2011 until January 2014. Only children with isolated sagittal synostosis were included in the study. Our modified Renier's technique reduces the possibility of lesion of superior sagittal sinus, dividing parietal bone in three bone fragments, thus achieving shortening of the scull in AP diameter without detaching the bone from the superior sagittal sinus. The possibility for potential secondary stenosis is minimized using extended V-shaped osteotomies with rounding of the bone edges, as well as making wide neocoronal and neolambdoid sutures. Cosmetic results were estimated as very pleasing immediately after surgery by both the parents and the surgeons in all cases. The majority of patients presented in our study were categorized as Sloan Class 1. Improvement or normalization of the cranial index was accomplished in all patients. No revision surgeries were required during the follow-up. Triple square extended osteotomies technique is a fast, simple, and efficient surgical option for children with sagittal synostosis and can be safely applied in the first months of life in children even under weight of 6 kilos. Preliminary results are encouraging and deserve a longer follow-up and comparative surgical analysis to verify its usefulness in the future.

Abstract
OBJECT
The authors’ aim was perform a systematic review on the incidence of intracranial hypertension (IH) after surgery for craniosynostosis.
METHODS
A systematic literature review was conducted using PubMed to assess the rate of postoperative IH in studies published between 1985 and 2014. Inclusion criteria were 1) English-language literature; 2) human subjects; 3) pediatric cases; and 4) postoperative IH confirmed with invasive intracranial pressure monitoring.
RESULTS
Seven studies met inclusion criteria. IH was reported to be present in 5% of patients postoperatively with sagittal synostosis and 4% of patients with all forms of nonsyndromic craniosynostosis. Inadequate numbers were available to determine the incidence of postoperative IH for syndromic and individual nonsyndromic sutural synostosis based on the inclusion criteria. Surgical groups were subdivided into cranial remodeling procedures without orbital advancement and craniofacial procedures with orbital advancement. IH was reported to be present in 5% of patients with all forms of nonsyndromic sutural stenosis after cranial remodeling procedures and 1% after craniofacial advancement.
CONCLUSIONS
Postoperative development of elevated intracranial pressure has been described by multiple institutions, but the variation in how IH is determined and the multiple surgical procedures to correct craniosynostosis has limited the number of studies subject to a meta-analysis. Nonetheless, this entity deserves special attention, and further studies are required to determine the true incidence of postoperative IH, including the role of various surgical procedures on its incidence. The long-term consequences of chronic IH in this group of patients also need to be evaluated.

Abstract
BACKGROUND Resulting from an early fusion of the sagittal suture, scaphocephaly (SC) is the most frequent form of all craniosynostosis and represents 40-60% of all cases. The scope of this study is to describe the first series of Renier's 'H' technique to be applied in children with SC outside of France. METHODS A consecutive review is made of the medical records of children hospitalized in the last 6 years (between March 2007 and March 2013) with isolated SC in whom Renier's 'H' technique was performed. RESULTS Thirteen children met the criteria for inclusion in the study. Considering medical evaluation and parental satisfaction, the evaluation of postsurgical cranial reconstruction was classified as satisfactory in all cases. CONCLUSIONS We consider the Renier's H technique to be effective in the cranial reshaping of children with isolated SC, with satisfactory esthetic postsurgical results.
