Endoscopic surgery for craniosynostosis: A systematic review and single-arm meta analysis. Clin Neurol Neurosurg 2024; 242:108296. [PMID: 38749357 DOI: 10.1016/j.clineuro.2024.108296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 04/21/2024] [Accepted: 04/22/2024] [Indexed: 06/16/2024]
Abstract
BACKGROUND Craniosynostosis, a developmental craniofacial anomaly, can impair brain development and cause abnormal skull shape due to premature closure of one or more cranial sutures. Traditional surgical treatments have evolved from open operations to minimally invasive endoscopic techniques. This systematic review and meta-analysis aim to evaluate the effectiveness and safety of the endoscopic approach in craniosynostosis correction. METHODS Adhering to Cochrane Group standards and the PRISMA framework, this review utilized databases like PubMed, Embase, and Web of Science, focusing on clinical and surgical outcomes of endoscopic craniosynostosis operations up to December 2023. Inclusion criteria emphasized studies with at least five patients undergoing endoscopic procedures, while exclusion criteria involved non-English papers, incomplete texts, and overlapping data. Statistical analysis used R software with various packages, and methodological bias was assessed using the ROBINS-I framework. RESULTS The review included 30 studies (4 prospective, 26 retrospective) with 2561 patients. The median age at operation was 3.20 months. Findings showed a mean operative time of 68.06 min, median hospital stay of 1.28 days, and mean blood loss of 29.89 ml. Blood transfusion was required in 9.97% of cases. Helmet therapy post-operation was common, with a median duration of 9 months. The rate of postoperative complications was 1.86%, and the reoperation rate was 3.07%. No procedure-related mortality was observed. The study noted substantial variations in the handling of craniosynostosis and a lack of consensus on the optimal timing and surgical approach. CONCLUSION Endoscopic techniques for craniosynostosis repair demonstrate safety and effectiveness, characterized by low complication risks and favorable surgical outcomes. However, due to the limitations of observational studies and inherent heterogeneity, further comprehensive and controlled trials are needed to validate these findings and understand the long-term outcomes of the endoscopic approach.

A computational modelling tool for prediction of head reshaping following endoscopic strip craniectomy and helmet therapy for the treatment of scaphocephaly. Comput Biol Med 2024; 177:108633. [PMID: 38805810 DOI: 10.1016/j.compbiomed.2024.108633] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 05/10/2024] [Accepted: 05/18/2024] [Indexed: 05/30/2024]
Abstract
BACKGROUND Endoscopic strip craniectomy followed by helmet therapy (ESCH) is a minimally invasive approach for correcting sagittal craniosynostosis. The treatment involves a patient-specific helmet designed to facilitate lateral growth while constraining sagittal expansion. In this study, finite element modelling was used to predict post-treatment head reshaping, improving our comprehension of the necessary helmet therapy duration. METHOD Six patients (aged 11 weeks to 9 months) who underwent ESCH at Connecticut Children's Hospital were enrolled in this study. Day-1 post-operative 3D scans were used to create skin, skull, and intracranial volume models. Patient-specific helmet models, incorporating areas for growth, were designed based on post-operative imaging. Brain growth was simulated through thermal expansion, and treatments were modelled according to post-operative Imaging available. Mechanical testing and finite element modelling were combined to determine patient-specific mechanical properties from bone samples collected from surgery. Validation compared simulated end-of-treatment skin surfaces with optical scans in terms of shape matching and cranial index estimation. RESULTS Comparison between the simulated post-treatment head shape and optical scans showed that on average 97.3 ± 2.1 % of surface data points were within a distance range of -3 to 3 mm. The cranial index was also accurately predicted (r = 0.91). CONCLUSIONS In conclusion, finite element models effectively predicted the ESCH cranial remodeling outcomes up to 8 months postoperatively. This computational tool offers valuable insights to guide and refine helmet treatment duration. This study also incorporated patient-specific material properties, enhancing the accuracy of the modeling approach.

[PMID: 38630329 DOI: 10.1007/s10143-024-02406-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 03/25/2024] [Accepted: 04/09/2024] [Indexed: 04/19/2024]
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.

Abstract
Premature fusion of craniofacial joints, i.e. sutures, is a major clinical condition. This condition affects children and often requires numerous invasive surgeries to correct. Minimally invasive external loading of the skull has shown some success in achieving therapeutic effects in a mouse model of this condition, promising a new non-invasive treatment approach. However, our fundamental understanding of the level of deformation that such loading has induced across the sutures, leading to the effects observed is severely limited, yet crucial for its scalability. We carried out a series of multiscale characterisations of the loading effects on normal and craniosynostotic mice, in a series of in vivo and ex vivo studies. This involved developing a custom loading setup as well as software for its control and a novel in situ CT strain estimation approach following the principles of digital volume correlation. Our findings highlight that this treatment may disrupt bone formation across the sutures through plastic deformation of the treated suture. The level of permanent deformations observed across the coronal suture after loading corresponded well with the apparent strain that was estimated. This work provides invaluable insight into the level of mechanical forces that may prevent early fusion of cranial joints during the minimally invasive treatment cycle and will help the clinical translation of the treatment approach to humans.

Abstract
OBJECTIVE The purpose of this study is to analyze cranial width and length growth curves in the early postoperative period of patients by undergoing endoscopic sagittal strip craniectomy (ESC) to determine the timing of the maximal growth curve change. By analyzing the complex interplay of cephalic length and width measurements, we hope to better understand the cephalic index (CI) growth curve during this early period. This is the first of a multistep process to elucidate the ideal cranial remolding orthosis (CRO) treatment duration. DESIGN Retrospective review. SETTING Tertiary academic institution. PATIENTS Children with isolated sagittal craniosynostosis. INTERVENTIONS ESC and postoperative CRO treatment (2015-2019). MAIN OUTCOME MEASURES One cranial orthotist obtained preoperative and postoperative measurements. The maximal rate of change of width, length, and CI were compared against the postoperative week these occurred. RESULTS Thirteen children (mean age: 3.3 months, average preoperative CI: 73.4) underwent this intervention. CI reached its highest growth rate by 4.9 average weeks postoperatively, which correlated with the maximal width growth rate (5.2 weeks). Length curves reached their maximal growth rate by 15.5 weeks. CI peaked (81.3) by 22.7 weeks postoperatively, a significant increase from baseline. CONCLUSIONS Following ESC, in the early postoperative period, the CI growth curve has 4 phases: initial rapid expansion, early and late slowed expansion, and plateau, followed by possible regression phases. This highlights the importance of early postoperative CRO initiation, CRO compliance, and properly fitting CROs, especially in the first 2 phases. This data sets the stage for investigating the ideal treatment length.

Abstract
BACKGROUND Unilateral coronal synostosis (UCS) results in a surgically demanding deformation, as the deformity is asymmetric in the calvaria but also presents with facial scoliosis and orbital dystopia. Traditional cranioplasties correct the forehead but have little effect on the face and orbits. In this article, the authors describe a consecutive series of patients operated on for UCS with osteotomy of the fused suture combined with distraction osteogenesis. METHODS Fourteen patients (mean age, 8.0 months; range, 4.3 to 16.6 months) were included in this study. The authors measured and compared the orbital dystopia angle, anterior cranial fossa deviation, and anterior cranial fossa cant between preoperative computed tomography results and those at distractor removal. RESULTS Blood loss was 6.1 mL/kg (range, 2.0 to 15.2 mL/kg), and length of stay was 4.4 days (range, 3.0 to 6.0 days). The authors observed significant improvements in the median orbital dystopia angle from 9.8 degrees (95% CI, 7.0 to 12.6 degrees) to 1.1 degrees (95% CI, -1.5 to 3.7 degrees) ( P < 0.001), anterior cranial fossa deviation from 12.9 degrees (95% CI, 9.2 to 16.6 degrees) to 4.7 degrees (95% CI, 1.5 to 7.9 degrees) ( P < 0.001), and anterior cranial fossa cant from 2.5 degrees (95% CI, 1.5 to 3.5 degrees) to 1.7 degrees (95% CI, 0.0 to 3.4 degrees) ( P = 0.003). CONCLUSIONS Osteotomy combined with a distractor for UCS straightened the face and relieved orbital dystopia by affecting the nose angle relative to the orbits, correcting the deviation of the cranial base in the anterior fossa, and lowering the orbit on the affected side. Furthermore, this technique demonstrated a favorable morbidity profile with low perioperative bleeding and a short inpatient period, suggesting its potential to improve the surgical treatment of UCS.

Abstract
OBJECTIVE Surgical correction of unicoronal synostosis (UCS) entails extensive cranioplasties which do not address facial scoliosis. This paper presents the first results with springs that motivated the shift from extensive cranioplasties to dynamic techniques for surgical correction of UCS. METHODS Two cases of UCS were operated with a linear osteotomy combined with springs. The deviation in facial symmetry (orbital dystopia angle) and skull base angles were measured on pre and postoperative computed tomography scans until 3 years of age. RESULTS The facial scoliosis was corrected. At spring removal, the orbital dystopia angle had gone from a 9.2 to 13.2-degree deviation preoperatively to a 0.5 to 0.9-degree overcorrection compared with the ideal 0-degree deviation. Also, the skull base deviation improved. CONCLUSION Linear osteotomy combined with springs corrects the facial scoliosis in UCS. These cases indicate that dynamic methods may be beneficial for improving the results of surgical correction of UCS.

Abstract
To present the outcomes and adverse events associated with the endoscopic-assisted, minimally invasive suturectomy in patients with multisuture synostosis. This retrospective cohort study included children < 65 days of age who underwent endoscopic-assisted suturectomy (EAS) for multisuture craniosynostosis at a single tertiary referral center from 2013 to 2021. The primary outcome was calvarial expansion, and the secondary outcome was adverse events. The pre- and post-operative 3-dimensional brain computed tomography (CT) scan was used to calculate the intracranial volume and cephalic index. During a period of 2 years, 10 infants (10-64 days) diagnosed with multisuture synostosis underwent single-stage EAS of every affected suture in our center. The coronal suture was the most prevalent involved suture among our cases. The mean age and weight of the patients were 39 ± 17.5 days and 4.39 ± 0.8 kg, respectively. The surgical procedure took 42 ± 17.4 min of time and caused 46 ± 25.4 mL of bleeding on average. Ninety percent of the operations were considered successful (n = 9) regarding calvarial expansion. There were two complications, one requiring an open vault surgery and one repairing a leptomeningeal cyst. In the eight patients who did not necessitate further interventions, the mean pre-operative intracranial volume was 643.3 ± 189.4 cm3. The follow-up results within the average of 38.9 months after surgery showed that as age increases, the intracranial volume also increased significantly (R: 0.6, P < 0.0001), which suggests continued skull growth in patients who underwent EAS. With the low rate of intra- or post-operative complications and promising results on revising the restricted skull sutures, EAS seems both a safe and effective therapeutic modality in patients with multisuture synostosis, especially if completed in the first months after birth.

Abstract
Minimally invasive suturectomy has been reported to significantly decrease the economic cost of treating infants with craniosynostosis. Nonetheless, treatment should be accompanied by a cranial remolding orthosis to maintain the constant correction and reshaping of the skull throughout the infant's development.

Abstract
BACKGROUND Endoscopic suturectomy with postoperative helmeting (ESCH) has emerged as a successful treatment for craniosynostosis, initially in North America. We report early outcomes from the first cohort of ESCH patients treated in the United Kingdom (UK). METHODS Retrospective cohort study with electronic chart review. RESULTS 18 consecutive patients from the first ESCH procedure in UK (May 2017) until January 2020 identified. 12 male and 6 female infantsd, with a mean age of 4.6 months (range 2.5-7.8 months) and weight of 6.8 kg (range 4.8-9.8 kg). Diagnoses were metopic (n = 8), unicoronal (n = 7), sagittal (n = 2) and multi-sutural (n = 1) synostoses. Median incision length was 3 cm (range 2-10 cm). 16/18 received no blood products, with 2 (both metopics) requiring transfusion (1 donor exposure). Mean operative time (including anaesthesia) was 96 min (range 40-127 min). Median length of hospital stay was 1 night. 1 surgical complication (superficial infection). All patients are currently undergoing helmet orthosis therapy. So far, no patients have required revisional or squint surgery. CONCLUSION Early experience from the first UK cohort of ESCH suggests that this is a safe and well tolerated technique with low morbidity, transfusion and short hospital stay. Long-term results in terms of shape, cosmetic and developmental outcome are awaited.

Abstract
OBJECTIVE Early suturectomy with a rigid endoscope followed by orthotic cranial helmet therapy is an accepted treatment option for single-suture craniosynostosis. To the authors' knowledge, flexible endoscope-assisted suture release (FEASR) has not been previously described. Presented herein is their experience with FEASR for the treatment of isolated sagittal craniosynostosis. METHODS A retrospective analysis of the health records of patients who had undergone FEASR between March 2018 and December 2020 was performed. Patients under the age of 6 months who had been diagnosed with isolated sagittal synostosis were considered eligible for FEASR. Exclusion criteria included syndromic synostosis or multiple-suture synostosis. The cephalic index, the primary measure of the cosmetic endpoint, was calculated at prespecified intervals: immediately preoperatively and 6 weeks and 12 months postoperatively. Parental satisfaction with the cosmetic outcome was determined throughout the clinical follow-up and documented according to a structured questionnaire for the first 12 months. RESULTS A total of 18 consecutive patients met the criteria for study inclusion. The mean patient age at the time of surgery was 3.4 months (range 2-6 months). All patients underwent a wide craniectomy with no need to convert to an open procedure. The mean craniectomy width was 3.61 cm. Estimated blood loss ranged from 5 to 30 ml. The mean operative time was 75 minutes. No intraoperative complications were observed. The average length of stay was 2.6 days. The mean cephalic index was 67.7 preoperatively, 77.1 at 6 weeks postoperatively, and 76.3 at 1 year postoperatively. The mean percentage change in the cephalic index from preoperatively to the 12-month follow-up was 10.44 (p < 0.001). The mean follow-up was 17 months (range 12-28 months). All parents were satisfied with the cosmetic outcome of the procedure. No patients developed symptoms of raised intracranial pressure (ICP) or needed invasive ICP monitoring during the follow-up period. No patients required reoperation. CONCLUSIONS In this modest single-hospital series, the authors demonstrated the feasibility of FEASR in treating sagittal synostosis with favorable cosmetic outcomes. The morbidity profile and resource utilization of the procedure appear similar to those of procedures conducted via traditional rigid endoscopy.

A preliminary analysis of replicating the biomechanics of helmet therapy for sagittal craniosynostosis. Childs Nerv Syst 2022; 39:989-996.

Abstract
PURPOSE The aim of this study was to investigate the biomechanics of endoscopically assisted strip craniectomy treatment for the management of sagittal craniosynostosis while undergoing three different durations of postoperative helmet therapy using a computational approach. METHODS A previously developed 3D model of a 4-month-old sagittal craniosynostosis patient was used. The strip craniectomy incisions were replicated across the segmented parietal bones. Areas across the calvarial were selected and constrained to represent the helmet placement after surgery. Skull growth was modelled and three variations of helmet therapy were investigated, where the timings of helmet removal alternated between 2, 5, and 8 months after surgery. RESULTS The predicted outcomes suggest that the prolonging of helmet placement has perhaps a beneficial impact on the postoperative long-term morphology of the skull. No considerable difference was found on the pattern of contact pressure at the interface of growing intracranial volume and the skull between the considered helmeting durations. CONCLUSION Although the validation of these simulations could not be performed, these simulations showed that the duration of helmet therapy after endoscopically assisted strip craniectomy influenced the cephalic index at 36 months. Further studies require to validate these preliminary findings yet this study can lay the foundations for further studies to advance our fundamental understanding of mechanics of helmet therapy.

J Neurosurg Pediatr 2022; 30:455-462.

Abstract
OBJECTIVE Endoscopic strip craniectomy with postoperative molding helmet therapy (ESC-H) and spring-assisted cranioplasty (SAC) are commonly used minimally invasive techniques for correction of nonsyndromic sagittal craniosynostosis, but it is unclear which, if either, is superior. Therefore, the authors undertook a systematic review to compare ESC-H with SAC for the surgical management of nonsyndromic single-suture sagittal craniosynostosis. METHODS Studies were identified through a systematic and comprehensive search of four databases (Embase, MEDLINE, and two databases in the Cochrane Library). Databases were searched from inception until February 19, 2021. Pediatric patients undergoing either ESC-H or SAC for the management of nonsyndromic single-suture sagittal craniosynostosis were included. Systematic reviews and meta-analyses, single-patient case reports, mixed cohorts of nonsyndromic and syndromic patients, mixed cohorts of different craniosynostosis types, and studies in which no outcomes of interest were reported were excluded. Outcomes of interest included reoperations, blood transfusion, complications, postoperative intensive care unit (ICU) admission, operative time, estimated blood loss, length of hospital stay, and cephalic index. Pooled summary cohort characteristics were calculated for each outcome of interest. Methodological quality was assessed using the Newcastle-Ottawa Scale. The study was reported in accordance with the 2020 PRISMA statement. RESULTS Twenty-two studies were eligible for inclusion in the review, including 1094 patients, of whom 605 (55.3%) underwent ESC-H and 489 (44.7%) underwent SAC for nonsyndromic sagittal craniosynostosis. There was no difference between the pooled estimates of the ESC-H and SAC groups for operative time, length of stay, estimated blood loss, and cephalic index. There was no difference between the groups for reoperation rate and complication rate. However, ESC-H was associated with a higher blood transfusion rate and higher postoperative ICU admission. CONCLUSIONS The available literature does not demonstrate superiority of either ESC-H or SAC, and outcomes are broadly similar for the treatment of nonsyndromic sagittal craniosynostosis. However, the evidence is limited by single-center retrospective studies with low methodological quality. There is a need for international multicenter randomized controlled trials comparing both techniques to gain definitive and generalizable data.

Abstract
While many centers nowadays offer minimally invasive techniques for the treatment of single suture synostosis, surgical techniques and patient management vary significantly. We provide an overview of how scaphocephaly treated with endoscopic techniques is managed in the reported series and analyze the crucial steps that need to be dealt with during the management process. We performed a review of the published literature including all articles that examined sagittal-suture synostosis treated with endoscopic techniques as part of single- or multicenter studies. Fourteen studies reporting results of 885 patients were included. We identified 5 key steps in the management of patients. A total of 188 patients were female and 537 male (sex was only specified in 10 articles, for 725 included patients, respectively). Median age at surgery was between 2.6 and 3.9 months with a total range from 1.5 to 7.0 months. Preoperative diagnostics included clinical and ophthalmologic examinations as well as neuropsychological and genetic consultations if needed. In 5 publications, a CT scan was routinely performed. Several groups used anthropometric measurements, mostly the cephalic index. All groups analyzed equally recommended to perform endoscopically assisted craniosynostosis surgery with postoperative helmet therapy in children < 3 months of age, at least for non-syndromic cases. There exist significant variations in surgical techniques and patient management for children treated endoscopically for single suture sagittal synostosis. This heterogeneity constitutes a major problem in terms of comparability between different strategies.

Abstract
Sagittal synostosis is the most occurring form of craniosynostosis, resulting in calvarial deformation and possible long-term neurocognitive deficits. Several surgical techniques have been developed to correct these issues. Debates as to the most optimal approach are still ongoing. Finite element method is a computational tool that's shown to assist with the management of craniosynostosis. The aim of this study was to compare and predict the outcomes of three reconstruction methods for sagittal craniosynostosis. Here, a generic finite element model was developed based on a patient at 4 months of age and was virtually reconstructed under all three different techniques. Calvarial growth was simulated to predict the skull morphology and the impact of different reconstruction techniques on the brain growth up to 60 months of age. Predicted morphology was then compared with in vivo and literature data. Our results show a promising resemblance to morphological outcomes at follow up. Morphological characteristics between considered techniques were also captured in our predictions. Pressure outcomes across the brain highlight the potential impact that different techniques have on growth. This study lays the foundation for further investigation into additional reconstructive techniques for sagittal synostosis with the long-term vision of optimizing the management of craniosynostosis.

Abstract
PURPOSE OF REVIEW Craniosynostosis, a condition of premature cranial suture fusion, can have significantly detrimental effects on development and growth due to sequelae of increased intracranial hypertension (ICP), exophthalmos, and upper airway obstruction. Evolving surgical treatments now include distraction osteogenesis (DO) due to its many benefits relative to standard cranial vault remodeling procedures. This article provides an overview and update of different surgical applications of DO for patients with craniosynostosis. RECENT FINDINGS DO has been utilized successfully for single and multisuture craniosynostosis with or without midface hypoplasia to increase intracranial volume, decrease ICP and improve aesthetics. It has been applied in single suture synostosis, posterior vault DO, fronto-orbital advancement, monobloc DO and Le Fort III DO. DO has been applied through modification of traditional surgical procedures with success in maintaining goals of surgery while reducing risk. SUMMARY DO is still a relatively new and evolving surgical technique for patients with syndromic and nonsyndromic craniosynostosis. With promising benefits, consideration for each procedure should be weighed until longer-term data is available.

Abstract
The aim of this study was to capture preoperative, postoperative, and follow-up head shapes of male trigonocephaly patients who underwent fronto-orbital remodelling (FOR), using three-dimensional (3D) photography. Fifty-seven male infants with metopic synostosis operated on using standardized FOR during a 5-year period were included. All measurements were compared with those of an age-matched healthy control cohort (n = 253 for early postoperative comparison, n = 43 for the 1-year follow-up comparison) to determine the effect of FOR at 14 days and at 1 year post-surgery. Intracranial volume, frontal angle, nasofrontal angle, interfrontoparietal-interparietal ratio, and inter-orbital distances were measured 1 day preoperatively, 14 days and 1 year postoperatively. Mean age at surgery was 9.7 ± 1.1 months. Prior to surgery, boys with metopic synostosis showed a reduced intracranial volume (-7.0%, P < 0.001), frontal angle (-10.2%, P < 0.001), interfrontoparietal-interparietal ratio (-4.9%, P < 0.01), and orbital distances (-6.5%, P < 0.001) compared to the reference group, but values did not differ significantly from the specific control group after surgery (all P> 0.05). This was consistent by the time of the follow-up examination. Corrective surgery should therefore aim to achieve volume expansion and correction of the deformity. Furthermore, 3D photogrammetry provides a valuable alternative to computed tomography scans in the diagnosis of metopic synostosis, significantly reducing the amount of radiation exposure to the brain.

Abstract
BACKGROUND Despite advancements in craniosynostosis surgery, open surgical approaches remain crucial for the management of infants >6 months of age and in those with complex synostosis. The clinical features of craniosynostosis remain poorly characterized in the Middle East. This study sought to assess the clinical features and outcomes of infants undergoing craniosynostosis surgery at a tertiary care center in Lebanon. METHODS A retrospective review was performed of all patients who underwent craniosynostosis surgery from December 2006 to December 2018 at the American University of Beirut Medical Center, Lebanon. Clinicodemographic characteristics, complications, and recurrence outcomes were recorded and evaluated using descriptive statistics. RESULTS Thirty-five infants met the inclusion criteria, with a mean age of 9.0 ± 4.0 months. The most common site of suture involvement was metopic (28.6%), followed by unilateral coronal (25.7%), sagittal (20.0%), bicoronal (8.6%), and multiple sites (17.1%). Five patients (14.3%) had syndromic synostosis. Median estimated blood loss was 200 mL, and median volume of transfused packed red blood cells was 180 mL. Two patients (5.7%) experienced postoperative complications, including postoperative blood transfusion (n = 1)and wire protrusion requiring removal (n = 1). Three patients (8.6%) required reoperation: 2 (5.7%) for resynostosis and 1 for traumatic fracture repair. Caregivers of all patients reported high satisfaction with cosmetic outcomes 4 weeks postoperatively. CONCLUSIONS With appropriate perioperative precautions, open craniosynostosis surgery can be performed with minimal complications, low recurrence rates, and satisfactory cosmetic outcomes. Additional population-level data are needed to better characterize craniosynostosis patterns and outcomes in the Middle East.

Abstract
Positional plagiocephaly is increasing in infants. Positional plagiocephaly is an asymmetric deformation of skull due to various reasons; first birth, assisted labor, multiple pregnancy, prematurity, congenital muscular torticollis and position of head. Positional plagiocephaly can mostly be diagnosed clinically and by physical examinations. The simplest way to assess the severity of plagiocephaly is to use a diagonal caliper during physical examination, which measures the difference between the diagonal lengths on each side of the head. Plagiocephaly can be treated surgically or conservatively. Positional plagiocephaly, which is not accompanied by craniosynostosis, is treated conservatively. Conservative treatments involve a variety of treatments, such as change of positions, physiotherapy, massage therapy, and helmet therapy. Systematic approaches to clinical examination, diagnosis and treatment of positional plagiocephaly can be necessary and the age-appropriate treatment is recommended for patients with positional plagiocephaly.
