Abstract
OBJECTIVE Open and endoscope-assisted repair are surgical options for sagittal craniosynostosis, with limited research evaluating each technique's immediate and long-term costs. This study investigates the cost-effectiveness of open and endoscope-assisted repair for single, sagittal suture craniosynostosis. METHODS The authors performed a retrospective cohort study of patients undergoing single, sagittal suture craniosynostosis repair (open in 17 cases, endoscope-assisted in 16) at less than 1 year of age at Monroe Carell Jr. Children's Hospital at Vanderbilt (MCJCHV) between August 2015 and August 2017. Follow-up data were collected/analyzed for 1 year after discharge. Surgical and follow-up costs were derived by merging MCJCHV financial data with each patient's electronic medical record (EMR) and were adjusted for inflation using the healthcare Producer Price Index. Proxy helmet costs were derived from third-party out-of-pocket helmet prices. To account for variable costs and probabilities, overall costs were calculated using TreeAge tree diagram software. RESULTS Open repair occurred in older patients (mean age 5.69 vs 2.96 months, p < 0.001) and required more operating room time (median 203 vs 145 minutes, p < 0.001), more ICU days (median 3 vs 1 day, p < 0.001), more hospital days (median 4 vs 1 day, p < 0.001), and more frequently required transfusion (88% vs 6% of cases). Compared to patients who underwent open surgery, patients who underwent endoscopically assisted surgery more often required postoperative orthotic helmets (100% vs 6%), had a similar number of follow-up clinic visits (median 3 vs 3 visits, p = 0.487) and CT scans (median 3 vs 2 scans), and fewer emergency department visits (median 1 vs 3 visits). The TreeAge diagram showed that, overall, open repair was 73% more expensive than endoscope-assisted repair ($31,314.10 vs $18,081.47). Sensitivity analysis identified surgical/hospital costs for open repair (mean $30,475, SEM $547) versus endoscope-assisted repair (mean $13,746, SEM $833) (p < 0.001) as the most important determinants of overall cost. Two-way sensitivity analysis comparing initial surgical/hospital costs confirmed that open repair remains significantly more expensive under even worst-case initial repair scenarios ($3254.81 minimum difference). No major surgical complications or surgical revisions occurred in either cohort. CONCLUSIONS The results of this study suggest that endoscope-assisted craniosynostosis repair is significantly more cost-effective than open repair, based on markedly lower costs and similar outcomes, and that the difference in initial surgical/hospital costs far outweighs the difference in subsequent costs associated with helmet therapy and outpatient management, although independent replication in a multicenter study is needed for confirmation due to practice and cost variation across institutions. Longer-term results will also be needed to examine whether cost differences are maintained.

A comparison of endoscopic strip craniectomy and pi craniectomy for treatment of sagittal craniosynostosis. J Neurosurg Pediatr 2019; 23:708-714. [PMID: 30925476 DOI: 10.3171/2019.1.peds18203] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2018] [Accepted: 01/14/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Sagittal craniosynostosis is managed with a wide variety of operative strategies. The current investigation compares the clinical outcomes of two widely performed techniques: pi craniectomy and minimally invasive endoscopic strip craniectomy (ESC) followed by helmet therapy. METHODS This IRB-approved retrospective study examined patients diagnosed with nonsyndromic, single-suture sagittal craniosynostosis treated with either pi craniectomy or ESC. Included patients had a minimum postoperative follow-up of 5 months. RESULTS Fifty-one patients met the inclusion criteria (pi 21 patients, ESC 30 patients). Compared to patients who underwent ESC, the pi patients were older at the time of surgery (mean age 5.06 vs 3.11 months). The mean follow-up time was 23.2 months for ESC patients and 31.4 months for pi patients. Initial cranial index (CI) was similar between the groups, but postoperatively the ESC patients experienced a 12.3% mean increase in CI (from 0.685 to 0.767) compared to a 5.34% increase for the pi patients (from 0.684 to 0.719), and this difference was statistically significant (p < 0.001). Median hospital length of stay (1 vs 2 days) and operative duration (69.5 vs 93.3 minutes) were significantly less for ESC (p < 0.001 for both). The ESC patients showed a trend toward better results when surgery was done at younger ages. Craniectomy width in ESC cases was positively associated with CI improvement (slope of linear regression = 0.69, p = 0.026). CONCLUSIONS While both techniques effectively treated sagittal craniosynostosis, ESC showed superior results compared to pi craniectomy. ESC showed a trend for better outcomes when done at younger ages, although the trend did not reach statistical significance. A wider craniectomy width (up to 2 cm) was associated with better outcomes than smaller craniectomy widths among the ESC patients.

Calculated Blood Loss and Transfusion Requirements in Primary Open Repair of Craniosynostosis. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2112. [PMID: 30881839 PMCID: PMC6416122 DOI: 10.1097/gox.0000000000002112] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2018] [Accepted: 11/26/2018] [Indexed: 12/05/2022]
Abstract
Background: Open surgical correction is effective in the treatment of craniosynostosis but may result in significant blood loss and transfusions. This study seeks to compare surgeon estimated blood loss with calculated blood loss and provide contemporary data that objectively quantify blood loss and transfusion rate associated with open repair of craniosynostosis. Methods: A retrospective review of patients undergoing primary open repair of craniosynostosis between May 2011 and November 2016 was performed. The medical records of 43 patients were reviewed to obtain the operative age, weight, affected suture, pre- and postoperative hematocrit, blood transfusion volume, estimated blood loss, and syndromic status. Estimated blood volume (EBV) and red cell mass were calculated for analysis. Results: The median age and weight at the time of surgery were 9 months and 8.6 kg, respectively. Mean surgeon estimated blood loss was 207.4 mL (28.1% of EBV). Mean calculated blood loss was 318 mL (44.3% of EBV). The mean transfusion volume was 188 mL (26.5% of EBV). The mean transfusion as a percent of estimated red cell mass was 59.1%. Fourteen percent of patients did not require any transfusion. Conclusions: We report intraoperative blood losses and transfusion requirements that are lower than those of many previous studies of open repair of craniosynostosis. Additionally, we found that calculated blood loss estimates may be more reliable than surgeon-derived estimated blood loss. We hope that these updated, objective data will be useful in comparisons of open repair to minimally invasive surgery or to new blood loss reducing procedures.

Abstract
OBJECTIVEMetrics used to quantify preoperative severity and postoperative outcomes for patients with sagittal synostosis include cephalic index (CI), the well-known standard, and the recently described adjusted cephalic index (aCI), which accounts for altered euryon location. This study tracks the time course of these measures following endoscopic repair with orthotic helmet therapy. The authors hypothesize that CI and aCI show significant regression following endoscope-assisted repair.METHODSCT scans or 3D photographs of patients with nonsyndromic sagittal synostosis treated before 6 months of age by endoscope-assisted strip craniectomy and postoperative helmet therapy (n = 41) were reviewed retrospectively at three time points (preoperatively, 0-2 months after helmeting, and > 24 months postoperatively). The CI and aCI were measured at each time point.RESULTSMean CI and aCI increased from 71.8 to 78.2 and 62.7 to 72.4, respectively, during helmet treatment (p < 0.001). At final follow-up, mean CI and aCI had regressed significantly from 78.2 to 76.5 and 72.4 to 69.7, respectively (p < 0.001). The CI regressed in 33 of 41 cases (80%) and aCI in 39 of 41 cases (95%). The authors observed a mean loss of 31% of improvement in aCI achieved through treatment. A strong, positive correlation existed between CI and aCI (R = 0.88).CONCLUSIONSRegression following endoscope-assisted strip craniectomy with postoperative helmet therapy commonly occurs in patients with sagittal synostosis. Future studies are required to determine whether duration of helmet therapy or modifications in helmet design affect regression.

Abstract
BACKGROUND The North American Pediatric Craniofacial Collaborative Group (PCCG) established the Pediatric Craniofacial Surgery Perioperative Registry to evaluate outcomes in infants and children undergoing craniosynostosis repair. The goal of this multicenter study was to utilize this registry to assess differences in blood utilization, intensive care unit (ICU) utilization, duration of hospitalization, and perioperative complications between endoscopic-assisted (ESC) and open repair in infants with craniosynostosis. We hypothesized that advantages of ESC from single-center studies would be validated based on combined data from a large multicenter registry. METHODS Thirty-one institutions contributed data from June 2012 to September 2015. We analyzed 1382 infants younger than 12 months undergoing open (anterior and/or posterior cranial vault reconstruction, modified-Pi procedure, or strip craniectomy) or endoscopic craniectomy. The primary outcomes included transfusion data, ICU utilization, hospital length of stay, and perioperative complications; secondary outcomes included anesthesia and surgical duration. Comparison of unmatched groups (ESC: N = 311, open repair: N = 1071) and propensity score 2:1 matched groups (ESC: N = 311, open repair: N = 622) were performed by conditional logistic regression analysis. RESULTS Imbalances in baseline age and weight are inherent due to surgical selection criteria for ESC. Quality of propensity score matching in balancing age and weight between ESC and open groups was assessed by quintiles of the propensity scores. Analysis of matched groups confirmed significantly reduced utilization of blood (26% vs 81%, P < .001) and coagulation (3% vs 16%, P < .001) products in the ESC group compared to the open group. Median blood donor exposure (0 vs 1), anesthesia (168 vs 248 minutes) and surgical duration (70 vs 130 minutes), days in ICU (0 vs 2), and hospital length of stay (2 vs 4) were all significantly lower in the ESC group (all P < .001). Median volume of red blood cell administered was significantly lower in ESC (19.6 vs 26.9 mL/kg, P = .035), with a difference of approximately 7 mL/kg less for the ESC (95% confidence interval for the difference, 3-12 mL/kg), whereas the median volume of coagulation products was not significantly different between the 2 groups (21.2 vs 24.6 mL/kg, P = .73). Incidence of complications including hypotension requiring treatment with vasoactive agents (3% vs 4%), venous air embolism (1%), and hypothermia, defined as <35°C (22% vs 26%), was similar between the 2 groups, whereas postoperative intubation was significantly higher in the open group (2% vs 10%, P < .001). CONCLUSIONS This multicenter study of ESC versus open craniosynostosis repair represents the largest comparison to date. It demonstrates striking advantages of ESC for young infants that may result in improved clinical outcomes, as well as increased safety.

Abstract
The authors compared the effectiveness of two main surgical techniques used for treating sagittal craniosynostosis (SC): endoscopic suturectomy (ES) and cranial vault remodeling (CVR). The safety, head growth, and aesthetic results following ES and CVR were compared by reviewing the charts of more than 200 patients. By comparing the effectiveness of these two treatments, this study will help guide selection of the optimal surgical treatment for patients with SC.

Abstract
OBJECTIVE Despite increasing adoption of endoscopic techniques for repair of nonsagittal single-suture craniosynostosis, the efficacy and safety of the procedure relative to established open approaches are unknown. In this systematic review the authors aimed to directly compare open surgical and endoscope-assisted techniques for the treatment of metopic, unilateral coronal, and lambdoid craniosynostosis, with an emphasis on quantitative reported outcomes. METHODS A literature search was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from 3 electronic databases (MEDLINE, EMBASE, and CENTRAL [Cochrane Central Register of Controlled Trials]) from their inception to August 2017. The quality of methodology and bias risk were assessed using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. RESULTS Of 316 screened records, 7 studies were included in a qualitative synthesis of the evidence, of which none were eligible for meta-analysis. These reported on 111 unique patients with metopic, 65 with unilateral coronal, and 12 with lambdoid craniosynostosis. For all suture types, 100 (53%) children underwent endoscope-assisted craniosynostosis surgery and 32 (47%) patients underwent open repair. These studies all suggest that blood loss, transfusion rate, operating time, and length of hospital stay were superior for endoscopically treated children. Although potentially comparable or better cosmetic outcomes are reported, the paucity of evidence and considerable variability in outcomes preclude meaningful conclusions. CONCLUSIONS Limited data comparing open and endoscopic treatments for metopic, unilateral coronal, and lambdoid synostosis suggest a benefit for endoscopic techniques with respect to blood loss, transfusion, length of stay, and operating time. This report highlights shortcomings in evidence and gaps in knowledge regarding endoscopic repair of nonsagittal single-suture craniosynostosis, emphasizing the need for further matched-control studies.

Abstract
OBJECTIVE In this paper the authors review their 16-year single-institution consecutive patient experience in the endoscopic treatment of nonsyndromic craniosynostosis with an emphasis on careful review of any associated treatment-related complications and methods of complication avoidance, including preoperative planning, intraoperative management, and postoperative care and follow-up. METHODS A retrospective chart review was conducted on all patients undergoing endoscopic, minimally invasive surgery for nonsyndromic craniosynostosis at Rady Children's Hospital from 2000 to 2015. All patients were operated on by a single neurosurgeon in collaboration with two plastic and reconstructive surgeons as part of the institution's craniofacial team. RESULTS Two hundred thirty-five patients underwent minimally invasive endoscopic surgery for nonsyndromic craniosynostosis from 2000 to 2015. The median age at surgery was 3.8 months. The median operative and anesthesia times were 55 and 105 minutes, respectively. The median estimated blood loss (EBL) was 25 ml (median percentage EBL 4.2%). There were no identified episodes of air embolism or operative deaths. One patient suffered an intraoperative sagittal sinus injury, 2 patients underwent intraoperative conversion of planned endoscopic to open procedures, 1 patient experienced a dural tear, and 1 patient had an immediate reexploration for a developing subgaleal hematoma. Two hundred twenty-five patients (96%) were admitted directly to the standard surgical ward where the median length of stay was 1 day. Eight patients were admitted to the intensive care unit (ICU) postoperatively, 7 of whom had preexisting medical conditions that the team had identified preoperatively as necessitating a planned ICU admission. The 30-day readmission rate was 1.7% (4 patients), only 1 of whom had a diagnosis (surgical site infection) related to their initial admission. Average length of follow-up was 2.8 years (range < 1 year to 13.4 years). Six children (< 3%) had subsequent open procedures for perceived suboptimal aesthetic results, 4 of whom (> 66%) had either coronal or metopic craniosynostosis. No patient in this series either presented with or subsequently developed signs or symptoms of intracranial hypertension. CONCLUSIONS In this large single-center consecutive patient series in the endoscopic treatment of nonsyndromic craniosynostosis, significant complications were avoided, allowing for postoperative care for the vast majority of infants on a standard surgical ward. No deaths, catastrophic postoperative morbidity, or evidence of the development of symptomatic intracranial hypertension was observed.

Abstract
OBJECTIVE In this systematic review and meta-analysis the authors aimed to directly compare open surgical and endoscope-assisted techniques for the treatment of sagittal craniosynostosis, focusing on the outcomes of blood loss, transfusion rate, length of stay, operating time, complication rate, cost, and cosmetic outcome. METHODS A literature search was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from 3 electronic databases (MEDLINE, EMBASE, and CENTRAL [Cochrane Central Register of Controlled Trials]) from their inception to August 2017. The quality of methodology and bias risk were assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Effect estimates between groups were calculated as standardized mean differences with 95% CIs. Random and fixed effects models were used to estimate the overall effect. RESULTS Of 316 screened records, 10 met the inclusion criteria, of which 3 were included in the meta-analysis. These studies reported on 303 patients treated endoscopically and 385 patients treated with open surgery. Endoscopic surgery was associated with lower estimated blood loss (p < 0.001), shorter length of stay (p < 0.001), and shorter operating time (p < 0.001). From the literature review of the 10 studies, transfusion rates for endoscopic procedures were consistently lower, with significant differences in 4 of 6 studies; the cost was lower, with differences ranging from $11,603 to $31,744 in 3 of 3 studies; and the cosmetic outcomes were equivocal (p > 0.05) in 3 of 3 studies. Finally, endoscopic techniques demonstrated complication rates similar to or lower than those of open surgery in 8 of 8 studies. CONCLUSIONS Endoscopic procedures are associated with lower estimated blood loss, operating time, and days in hospital. Future long-term prospective registries may establish advantages with respect to complications and cost, with equivalent cosmetic outcomes. Larger studies evaluating patient- or parent-reported satisfaction and optimal timing of intervention as well as heterogeneity in outcomes are indicated.

Abstract
INTRODUCTION Surgery for craniosynostosis remains a crucial element in successful management. Intervention by both endoscopic and open approaches has been proven effective. Given the differences in timing and indications for these procedures, differences in perioperative outcomes have yet to be thoroughly compared between the two approaches. The aim of the systematic review and meta-analysis was to assess the available evidence of perioperative outcomes between the two approaches in order to better influence the management paradigm of craniosynostosis. METHODS We followed recommended PRISMA guidelines for systematic reviews. Seven electronic databases were searched to identify all potentially relevant studies published from inception to February 2018 which were then screened against a set of selection criteria. Data were extracted and analyzed using meta-analysis of proportions. RESULTS Twelve studies satisfied all the selection criteria to be included, which described a pooled cohort involving 2064 craniosynostosis patients, with 965 (47%) and 1099 (53%) patients undergoing surgery by endoscopic and open approaches respectively. When compared to the open approach, it was found that the endoscopic approach conferred statistically significant reductions in blood loss (MD = 162.4 mL), operative time (MD = 112.38 min), length of stay (MD = 2.56 days), and rates of perioperative complications (OR = 0.58), reoperation (OR = 0.37) and transfusion (OR = 0.09), where all p < 0.001. CONCLUSION Both endoscopic and open approaches for the surgical management of craniosynostosis are viable considerations. The endoscopic approach confers a significant reduction in operative and postoperative morbidity when compared to the open approach. Given that specific indications for either approach should be considered when managing a patient, the difference in perioperative outcomes remain an important element of this paradigm. Future studies will validate the findings of this study and consider long-term outcomes, which will all contribute to rigor of craniosynostosis management.

Abstract
OBJECTIVE Endoscope-assisted repair of craniosynostosis is a safe and efficacious alternative to open techniques. However, this procedure is challenging to learn, and there is significant variation in both its execution and outcomes. Surgical simulators may allow trainees to learn and practice this procedure prior to operating on an actual patient. The purpose of this study was to develop a realistic, relatively inexpensive simulator for endoscope-assisted repair of metopic and sagittal craniosynostosis and to evaluate the models' fidelity and teaching content. METHODS Two separate, 3D-printed, plastic powder-based replica skulls exhibiting metopic (age 1 month) and sagittal (age 2 months) craniosynostosis were developed. These models were made into consumable skull "cartridges" that insert into a reusable base resembling an infant's head. Each cartridge consists of a multilayer scalp (skin, subcutaneous fat, galea, and periosteum); cranial bones with accurate landmarks; and the dura mater. Data related to model construction, use, and cost were collected. Eleven novice surgeons (residents), 9 experienced surgeons (fellows), and 5 expert surgeons (attendings) performed a simulated metopic and sagittal craniosynostosis repair using a neuroendoscope, high-speed drill, rongeurs, lighted retractors, and suction/irrigation. All participants completed a 13-item questionnaire (using 5-point Likert scales) to rate the realism and utility of the models for teaching endoscope-assisted strip suturectomy. RESULTS The simulators are compact, robust, and relatively inexpensive. They can be rapidly reset for repeated use and contain a minimal amount of consumable material while providing a realistic simulation experience. More than 80% of participants agreed or strongly agreed that the models' anatomical features, including surface anatomy, subgaleal and subperiosteal tissue planes, anterior fontanelle, and epidural spaces, were realistic and contained appropriate detail. More than 90% of participants indicated that handling the endoscope and the instruments was realistic, and also that the steps required to perform the procedure were representative of the steps required in real life. CONCLUSIONS Both the metopic and sagittal craniosynostosis simulators were developed using low-cost methods and were successfully designed to be reusable. The simulators were found to realistically represent the surgical procedure and can be used to develop the technical skills required for performing an endoscope-assisted craniosynostosis repair.

Abstract
Craniosynostosis (CS) is defined as the premature fusion of one or more calvarial sutures. This carries several consequences, including abnormal/asymmetric cranial vault development, increased intracranial pressure, compromised neurocognitive development, and craniofacial deformity. Definitive management is surgical with the goal of protecting cerebral development by re-establishing normal cranial vault expansion and correcting cosmetic deformity. In today's practice, CS surgery has advanced radically from simple craniectomies to major cranial vault reconstructive (CVR) procedures. More recently there has been considerable interest in endoscopic assisted surgery (EAS). Theoretical benefits include decreased operative time, morbidity, blood loss, postoperative pain, cost and faster recovery times. In this focused review, we summarize the current body of literature reporting clinical outcomes in EAS and review the data comparing EAS and CVR.

Abstract
Background Surgical methods to treat craniosynostosis have evolved from a simple strip craniectomy to a diverse spectrum of partial or complete cranial vault remodeling with excellent results but often with high comorbidity. Therefore, minimal invasive craniosynostosis surgery has been explored in the last few decades. The main goal of minimal invasive craniosynostosis surgery is to reduce the morbidity and invasiveness of classical surgical procedures, with equal long-term results, both functional as well as cosmetic. Methods To reach these goals, we adopted endoscopy-assisted craniosynostosis surgery (EACS) supplemented with helmet molding therapy in 2005. Results We present in detail our surgical technique used for scaphocephaly, trigonocephaly, plagiocephaly, complex multisutural, and syndromic cases of craniosynostosis. Conclusions We conclude that EACS with helmet therapy is a safe and suitable treatment option for any type of craniosynostosis, if performed at an early age, preferably around 3 months of age.

Abstract
OBJECTIVE To compare postoperative temporal expansion in patients treated with fronto-orbital advancement or endoscopy-assisted craniectomy with cranial orthotic therapy. DESIGN This is a retrospective, multicenter cohort study of patients with unilateral coronal craniosynostosis (UCS). SETTING Computed tomographic (CT) scans were drawn from UCS patients treated at Boston Children's Hospital or St Louis Children's Hospital. PATIENTS The study included 56 patients with UCS after fronto-orbital advancement (n = 32) or endoscopic repair (n = 24) and 10 age-matched controls. INTERVENTION Fronto-orbital advancement entails a craniotomy of the frontal bone and superior orbital rim followed by reshaping and forward advancement. Endoscopic repair is the release of the synostotic suture and guidance of further growth of the cranium using a molding orthotic. MAIN OUTCOME MEASURES Measures included posterior temporal width, anterior temporal width, orbital width, and anterior cranial fossa area taken preoperatively and 1 year postoperatively. Linear regression was performed to assess 1 year postoperative improvement in symmetry; covariates included preoperative symmetry and type of surgery. RESULTS Both treatments showed improvement in orbital width and anterior cranial fossa area symmetry 1 year postoperatively ( P < .001), but no significant improvement in posterior or anterior temporal width symmetry. Linear regression revealed no difference between the 2 procedures in any of the 4 measurements (.096 ≤ P ≤ .898). CONCLUSIONS Fronto-orbital advancement and endoscopic repair show equivalent outcomes 1 year postoperatively in all 3 width measurements and anterior cranial fossa area. Neither procedure produced significant improvement in temporal width.

Abstract
OBJECTIVE Endoscope-assisted repair of sagittal craniosynostosis was adopted at St. Louis Children's Hospital in 2006. This study examines the first 100 cases and reviews the outcomes and evolution of patient care protocols at our institution. METHODS The authors performed a retrospective chart review of the first 100 consecutive endoscopic repairs of sagittal craniosynostosis between 2006 and 2014. The data associated with length of hospital stay, blood loss, transfusion rates, operative times, cephalic indices (CIs), complications, and cranial remolding orthosis were reviewed. Measurements were taken from available preoperative and 1-year postoperative 3D reconstructed CT scans. RESULTS The patients' mean age at surgery was 3.3 ± 1.1 months. Of the 100 patients, 30 were female and 70 were male. The following perioperative data were noted. The mean operative time (± SD) was 77.1 ± 22.2 minutes, the mean estimated blood loss was 34.0 ± 34.8 ml, and the mean length of stay was 1.1 ± 0.4 days; 9% of patients required transfusions; and the mean pre- and postoperative CI values were 69.1 ± 3.8 and 77.7 ± 4.2, respectively. Conversion to open technique was required in 1 case due to presence of a large emissary vein that was difficult to control endoscopically. The mean duration of helmet therapy was 8.0 ± 2.9 months. Parietal osteotomies were eventually excluded from the procedure. CONCLUSIONS The clinical outcomes and improvements in CI seen in our population are similar to those seen at other high-volume centers. Since the inception of endoscope-assisted repair at our institution, the patient care protocol has undergone several significant changes. We have been able to remove less cranium using our "narrow-vertex" suturectomy technique without affecting patient safety or outcome. Patient compliance with helmet therapy and collaborative care with the orthotists remain the most essential aspects of a successful outcome.

Abstract
BACKGROUND Asymmetric multisutural craniosynostosis (AMC) is characterized by fusion of a midline suture combined with unilateral fusion of at least 1 nonmidline suture. Due to its rarity, complexity, and high rate of reoperation, the purpose of this study is to evaluate outcomes of our staged approach to AMC. METHODS Patients treated for craniosynostosis between January 2004 and December 2013 were identified retrospectively. Only patients with AMC and a minimum follow-up of 2 years were included. The 3-staged algorithm includes: extended strip craniectomy of fused sutures; postoperative helmet molding; and fronto-orbital advancement versus a touch-up procedure. Morphologic, aesthetic, and functional outcomes were evaluated. RESULTS Nine patients (6.8% of cases) were treated for AMC (mean follow-up: 4.1 years). Sixty-seven percent of patients (6 of 9) demonstrated signs of elevated intracranial pressure. Patients were divided into 2 groups: "Group A" included patients treated according to the staged algorithm (n = 5); "Group B" included those treated by traditional techniques (n = 4). Group A underwent their first calvarial vault procedure earlier than those from Group B (2.7 vs. 13.2 months; P < 0.02). Postoperatively, no Group A patients had developmental delay, signs of elevated intracranial pressure, or reoperation. Three of 5 patients (60%) were rated Whitaker Classification II and the others (40%) rated Whitaker Classification III. CONCLUSIONS Asymmetric multisutural synostosis results in a complex and evolving deformity involving the entire craniofacial complex. However, when asymmetric multisutural synostosis is approached in stages with early intervening helmet therapy, acceptable functional and appearance-related outcomes can be obtained with minimal complications.

Abstract
OBJECTIVE Endoscopic strip craniectomy (ESC) with postoperative helmet orthosis is a well-established treatment option for sagittal craniosynostosis. There are many technical variations to the surgery ranging from simple strip craniectomy to methods that employ multiple cranial osteotomies. The purpose of this study was to determine whether the addition of lateral barrel-stave osteotomies during ESC improved morphological outcomes. METHODS An IRB-approved retrospective review was conducted on a consecutive series of cases involving ESC for sagittal craniosynostosis at 2 different institutions from March 2008 to August 2014. The patients in Group A underwent ESC and those in Group B had ESC with lateral barrel-stave osteotomies. Demographic and perioperative data were recorded; postoperative morphological outcomes were analyzed using 3D laser scan data acquired from a single orthotic manufacturer who managed patients from both institutions. RESULTS A total of 73 patients were included (34 in Group A and 39 in Group B). Compared with Group B patients, Group A patients had a shorter mean anesthetic time (161.7 vs 195 minutes; p < 0.01) and operative time (71.6 vs 111 minutes; p < 0.01). The mean hospital stay was similar for the 2 groups (1.2 days for Group A vs 1.4 days for Group B; p = 0.1). Adequate postoperative data on morphological outcomes were reported by the orthotic manufacturer for 65 patients (29 in Group A and 36 in Group B). The 2 groups had similar improvement in the cephalic index (CI): Group A, mean change 10.5% (mean preoperative CI 72.6, final 80.4) at a mean follow-up of 13.2 months; Group B, mean change 12.2% (mean preoperative CI 71.0, final 79.6) at a mean follow-up of 19.4 months. The difference was not statistically significant (p = 0.15). CONCLUSIONS Both ESC alone and ESC with barrel staving produced excellent outcomes. However, the addition of barrel staves did not improve the results and, therefore, may not be warranted in the endoscopic treatment of sagittal craniosynostosis.

Abstract
OBJECTIVE Outcome studies for sagittal strip craniectomy have largely relied on the 2D measure of the cephalic index (CI) as the primary indicator of head shape. The goal of this study was to measure the 2D and 3D changes in head shape that occur after sagittal strip craniectomy and postoperative helmet therapy. METHODS The authors performed a retrospective review of patients treated with sagittal strip craniectomy at their institution between January 2012 and October 2015. Inclusion criteria were as follows: 1) isolated sagittal synostosis; 2) age at surgery < 200 days; and 3) helmet management by a single orthotist. The CI was calculated from 3D images. Color maps and dot maps were generated from 3D images to demonstrate the regional differences in the magnitude of change in head shape over time. RESULTS Twenty-one patients met the study inclusion criteria. The mean CI was 71.9 (range 63.0-77.9) preoperatively and 81.1 (range 73.0-89.8) at the end of treatment. The mean time to stabilization of the CI after surgery was 57.2 ± 32.7 days. The mean maximum distances between the surfaces of the preoperative and 1-week postoperative and between the surfaces of the preoperative and end-of-treatment 3D images were 13.0 ± 4.1 mm and 24.71 ± 6.83 mm, respectively. The zone of maximum change was distributed equally in the transverse and vertical dimensions of the posterior vault. CONCLUSIONS The CI normalizes rapidly after sagittal strip craniectomy (57.2 days), with equal distribution of the change in CI occurring before and during helmet therapy. Three-dimensional analysis revealed significant vertical and transverse expansion of the posterior cranial vault. Further studies are needed to assess the 3D changes that occur after other sagittal strip craniectomy techniques.

Abstract
BACKGROUND The authors' purpose is to present changes in anthropometric fronto-orbital dimensions after surgical correction of metopic synostosis. METHODS The authors retrospectively analyzed craniometric dimensions in older patients with metopic synostosis corrected by fronto-orbital advancement performed by the senior author (J.B.M.). Preoperative and postoperative linear measures (frontal breadth, cranial width, and intercanthal distance) were taken by direct anthropometry. Interdacryon distance and width of the bandeau were also recorded intraoperatively, before and after widening. Follow-up anthropometric values were compared to age- and sex-matched normative data and standard (z) scores were calculated. RESULTS Sixteen patients met the inclusion criteria. Syndromic diagnosis was documented in five of 16 patients. Average age at the last postoperative evaluation was 8.9 ± 3.8 years (range, 4 to 16 years). Mean frontal width z-scores decreased postoperatively from 0.82 to -0.32 (p = 0.007), indicating diminished growth in this dimension. The last measured frontal width strongly correlated with the breadth of the bandeau after surgical correction but not with preoperative values. Postoperative mean cranial width diminished significantly to a more normal value. Mean intercanthal distance was normal preoperatively and remained so but was significantly greater in syndromic than in nonsyndromic cases. CONCLUSIONS Frontal growth rate is diminished in the coronal plane after fronto-orbital advancement. The authors recommend primary techniques to overcorrect the width of the bandeau and frontal region, including zygomaticosphenoid osteotomies and interpositional cranial bone grafts to advance/widen the lateral orbital rim. Continued evaluation is required to assess whether overcorrection results in normal frontotemporal shape and breadth at skeletal maturity.

Abstract
OBJECTIVE Due to the changing properties of the infant skull, there is still no clear consensus on the ideal time to surgically intervene in cases of nonsyndromic craniosynostosis (NSC). This study aims to shed light on how patient age at the time of surgery may affect surgical outcomes and the subsequent need for reoperation. METHODS A retrospective cohort review was conducted for patients with NSC who underwent primary cranial vault remodeling between 1990 and 2013. Patients' demographic and clinical characteristics and surgical interventions were recorded. Postoperative outcomes were assessed by assigning each procedure to a Whitaker category. Multivariate logistic regression analysis was performed to determine the relationship between age at surgery and need for minor (Whitaker I or II) versus major (Whitaker III or IV) reoperation. Odds ratios (ORs) for Whitaker category by age at surgery were assigned. RESULTS A total of 413 unique patients underwent cranial vault remodeling procedures for NSC during the study period. Multivariate logistic regression demonstrated increased odds of requiring major surgical revisions (Whitaker III or IV) in patients younger than 6 months of age (OR 2.49, 95% CI 1.05-5.93), and increased odds of requiring minimal surgical revisions (Whitaker I or II) in patients older than 6 months of age (OR 2.72, 95% CI 1.16-6.41). CONCLUSIONS Timing, as a proxy for the changing properties of the infant skull, is an important factor to consider when planning vault reconstruction in NSC. The data presented in this study demonstrate that patients operated on before 6 months of age had increased odds of requiring major surgical revisions.

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
Endoscopic strip craniectomy with postoperative helmet therapy has been introduced as a means to correct various forms of craniosynostosis. Although some authors have deemed the procedure safe and effective, many questions remain regarding this promising yet developing approach. The authors discuss 4 cases where patients were inadequately treated with endoscopic strip craniectomy resulting in a recommendation of complete secondary open cranial vault reconstruction. In addition, the authors present the findings from an informal survey of craniofacial colleagues to highlight an important discrepancy between published and anecdotal reports of complications. Finally, the authors highlight the need for further investigation into the proper indications and clinical outcomes of endoscopic strip craniectomy to better understand the role of this technique in the treatment of craniosynostosis.

Abstract
OBJECTIVE Endoscope-assisted methods for treatment of craniosynostosis have reported benefits over open calvarial vault reconstruction. In this paper, the authors evaluated 2 methods for endoscope-assisted correction of sagittal synostosis: wide vertex suturectomy and barrel stave osteotomies (WVS+BSO) and narrow vertex suturectomy (NVS). METHODS The authors evaluated patients with nonsyndromic sagittal synostosis treated with either wide vertex suturectomy (4-6 cm) and barrel stave osteotomies (WVS+BSO) or narrow vertex suturectomy (NVS) (approximately 2 cm) between October 2006 and July 2013. Prospectively collected data included patient age, sex, operative time, estimated blood loss (EBL), postoperative hemoglobin level, number of transfusions, complications, and cephalic index. Fourteen patients in the NVS group were age matched to 14 patients in the WVS+BSO group. Descriptive statistics were calculated, and Student t-tests were used to compare prospectively obtained data from the WVS+BSO group with the NVS group in a series of univariate analyses. RESULTS The mean age at surgery was 3.9 months for WVS+BSO and 3.8 months for NVS. The mean operative time for patients undergoing NVS was 59.0 minutes, significantly less than the 83.4-minute operative time for patients undergoing WVS+BSO (p < 0.05). The differences in mean EBL (NVS: 25.4 ml; WVS+BSO: 27.5 ml), mean postoperative hemoglobin level (NVS: 8.6 g/dl; WVS+BSO: 8.0 g/dl), mean preoperative cephalic index (NVS: 69.9; WVS+BSO: 68.2), and mean cephalic index at 1 year of age (NVS: 78.1; WVS+BSO: 77.2) were not statistically significant. CONCLUSIONS The NVS and WVS+BSO produced nearly identical clinical results, as cephalic index at 1 year of age was similar between the 2 approaches. However, the NVS required fewer procedural steps and significantly less operative time than the WVS+BSO. The NVS group obtained the final cephalic index in a similar amount of time postoperatively as the WVS+BSO group. Complications, transfusion rates, and EBL were not different between the 2 techniques.

Abstract
OBJECTIVE The goal of this study was to identify the rate of neosuture formation in patients with craniosynostosis treated with endoscope-assisted strip craniectomy and investigate whether neosuture formation in sagittal craniosynostosis has an effect on postoperative calvarial shape. METHODS The authors retrospectively reviewed 166 cases of nonsyndromic craniosynostosis that underwent endoscope-assisted repair between 2006 and 2014. Preoperative and 1-year postoperative head CT scans were evaluated, and the rate of neosuture formation was calculated. Three-dimensional reconstructions of the CT data were used to measure cephalic index (CI) (ratio of head width and length) of patients with sagittal synostosis. Regression analysis was used to calculate significant differences between patients with and without neosuture accounting for age at surgery and preoperative CI. RESULTS Review of 96 patients revealed that some degree of neosuture development occurred in 23 patients (23.9%): 16 sagittal, 2 bilateral coronal, 4 unilateral coronal, and 1 lambdoid synostosis. Complete neosuture formation was seen in 14 of those 23 patients (9 of 16 sagittal, 1 of 2 bilateral coronal, 3 of 4 unilateral coronal, and 1 of 1 lambdoid). Mean pre- and postoperative CI in the complete sagittal neosuture group was 67.4% and 75.5%, respectively, and in the non-neosuture group was 69.8% and 74.4%, respectively. There was no statistically significant difference in the CI between the neosuture and fused suture groups preoperatively or 17 months postoperatively in patients with sagittal synostosis. CONCLUSIONS Neosuture development can occur after endoscope-assisted strip craniectomy and molding helmet therapy for patients with craniosynostosis. Although the authors did not detect a significant difference in calvarial shape postoperatively in the group with sagittal synostosis, the relevance of neosuture formation remains to be determined. Further studies are required to discover long-term outcomes comparing patients with and without neosuture formation.

Abstract
Various operative techniques are available for the treatment of craniosynostosis. The patient's age at presentation is one of the most important factors in the determination of the surgical modality. Minimally invasive suturectomy and postoperative helmet therapy may be performed for relatively young infants, whose age is younger than 6 months. It relies upon the potential for rapid brain growth in this age group. Its minimal invasiveness is also advantageous. In this article, we review the advantages and limitations of minimally invasive suturectomy followed by helmet therapy for the treatment of craniosynostosis.

Abstract
BACKGROUND Left-handedness is a highly conserved marker of cerebral functional laterality in the human population; elevated rates of left-handedness have been documented in patients with unilateral coronal synostosis treated with fronto-orbital advancement. The purpose of this study was to determine whether the prevalence of left-handedness in patients with nonsyndromic unilateral coronal synostosis is related to treatment. METHODS The incidence of left-handedness was compared among three groups: patients who were previously treated for unilateral coronal synostosis with endoscopic suturectomy and postoperative helmet therapy (group I); patients with unilateral coronal synostosis managed with fronto-orbital advancement (group II); and healthy, unaffected controls (group III). RESULTS Group I was composed of 19 patients; the side of synostosis was equally distributed (nine right and 10 left), and female gender was more common (n = 13). Mean age at endoscopic suturectomy and helmet therapy was 85.3 days, and the determination of handedness was performed at a mean age of 89.3 months. The rate of left-handedness in group I was 5.3 percent, not significantly different from that of the controls (group III) (11.5 percent) (p = 0.69) but significantly less than that observed in the fronto-orbital advancement patients (group II) (30.2 percent) (p = 0.023). CONCLUSIONS Patients who underwent endoscopic suturectomy and helmet therapy for nonsyndromic unilateral coronal synostosis and healthy controls demonstrated functional cerebral lateralization with respect to handedness that differed from patients who underwent fronto-orbital advancement. The reason may be related to the type of procedure, secondary effects of general anesthesia, or age at which the procedure was performed.

Abstract
OBJECT The authors present a retrospective cohort study examining complications in patients undergoing surgery for craniosynostosis using both minimally invasive endoscopic and open approaches. METHODS Over the past 10 years, 295 nonsyndromic patients (140 undergoing endoscopic procedures and 155 undergoing open procedures) and 33 syndromic patients (endoscopic procedures in 10 and open procedures in 23) met the authors' criteria. Variables analyzed included age at surgery, presence of a preexisting CSF shunt, skin incision method, estimated blood loss, transfusions of packed red blood cells, use of intravenous steroids or tranexamic acid, intraoperative durotomies, procedure length, and length of hospital stay. Complications were classified as either surgically or medically related. RESULTS In the nonsyndromic endoscopic group, the authors experienced 3 (2.1%) surgical and 5 (3.6%) medical complications. In the nonsyndromic open group, there were 2 (1.3%) surgical and 7 (4.5%) medical complications. Intraoperative durotomies occurred in 5 (3.6%) endoscopic and 12 (7.8%) open cases, were repaired primarily, and did not result in reoperations for CSF leakage. Similar complication rates were seen in syndromic cases. There was no death or permanent morbidity. Additionally, endoscopic procedures were associated with significantly decreased estimated blood loss, transfusions, procedure length, and length of hospital stay compared with open procedures. CONCLUSIONS Rates of intraoperative durotomies and surgical and medical complications were comparable between endoscopic and open techniques. This is the largest direct comparison to date between endoscopic and open interventions for synostosis, and the results are in agreement with previous series that endoscopic surgery confers distinct advantages over open surgery in appropriate patient populations.

Abstract
BACKGROUND The timing and surgical technique for the treatment of sagittal synostosis remain controversial. Calvarial vault remodeling (CVR), strip craniectomy (SC), and spring-mediated cranioplasty (SMC) are currently in use. We perform a meta-analysis of the literature to compare these 3 techniques. METHODS A literature search identified articles involving operative management of nonsyndromic sagittal synostosis. Comparison of 2 operative techniques was required, and methodology was assessed via the American Society of Plastic Surgeons' Levels of Evidence. Three techniques were considered: CVR, SC, and SMC. Meta-analysis was conducted for change in cephalic index (CI), reported as weighted mean difference (WMD). Pooled subgroup comparisons were performed for operative time, length of stay, blood loss, and cost. RESULTS Twelve studies providing level 2 or 3 evidence were included. All studies involved CVR (n = 187), 8 involved SC (n = 299), and 7 involved SMC (n = 158). Head-to-head comparison of change in CI demonstrated a greater, yet statistically insignificant change for CVR versus SMC, WMD = 0.94 (-0.23 to 2.11) (P = 0.12, I(2) = 55%). Calvarial vault remodeling showed a statistically greater change in CI versus SC, WMD = 1.47 (0.47-2.48) (P = 0.004, I(2) = 66%). Compared with SMC/SC, CVR had longer operative length (170 vs 97 minutes), higher blood loss (238 vs 47 mL), longer length of stay (5.1 vs 2.9 days), and higher costs ($35,280 vs $13,147), all with P < 0.0001. CONCLUSIONS This study, the first meta-analysis comparing 3 primary operations for correcting nonsyndromic sagittal synostosis, demonstrates no difference in CI for CVR versus SMC and a small but statistically greater improvement in CI favoring CVR over SC. Secondary outcomes favored SC/SMC procedures over CVR. However, long-term studies are still needed to adequately assess the risk-benefit ratios.

Abstract
BACKGROUND There have been conflicting reports on how sagittal synostosis affects cranial vault volume (CVV) and which surgical approach best normalizes skull volume. In this study, we compared CVV and cranial index (CI) of children with sagittal synostosis (before and after surgery) with those of control subjects. We also compared the effect of repair type on surgical outcome. METHODS Computed tomography scans of 32 children with sagittal synostosis and 61 age- and sex-matched control subjects were evaluated using previously validated segmentation software for CVV and CI. Sixteen cases underwent open surgery, and 16 underwent endoscopic surgery. Twenty-seven cases had both preoperative and postoperative scans. RESULTS Age of subjects at computed tomography scan ranged from 1 to 9 months preoperatively and 15 to 25 months postoperatively. Mean age difference between cases and matched control subjects was 5 days. The mean CVV of cases preoperatively was nonsignificantly (17 mL) smaller than that of control subjects (P = 0.51). The mean CVV of postoperative children was nonsignificantly (24 mL) larger than that of control subjects (P = 0.51). Adjusting for age and sex, there was no significant difference in CVV between open and endoscopic cases postoperatively (β = 48 mL, P = 0.31). The mean CI increased 12% in both groups. There was no significant difference in mean postoperative CI (P = 0.18) between the 2 groups. CONCLUSIONS Preoperatively, children with sagittal synostosis have no significant difference in CVV compared with control subjects. Type of surgery does not seem to affect CI and CVV 1 year postoperatively. Both open and endoscopic procedures result in CVVs similar to control subjects.

Abstract
Craniosynostosis and its associated abnormalities can pose unique challenges to surgeons caring for these patients. Cephalohematomas, although rare, add to the complexities of managing a patient with craniosynostosis. Here, we present the case of a 4-month-old male infant with concurrent sagittal craniosynostosis and a calcified cephalohematoma who underwent an endoscopic-assisted strip craniectomy and management of the hematoma with good results.

Abstract
Sagittal craniosynostosis, the most common single suture craniosynostosis, is treated by numerous surgical techniques. Minimally invasive endoscopy-assisted procedures with postoperative helmeting are being used with reports of good cosmetic outcomes with decreased morbidity, shortened hospital stay, and less blood loss and transfusion. This procedure uses small skin incisions, which must be properly placed to provide safe access to the posterior sagittal and lambdoid sutures. However, the lambda is often hard to palpate through the skin due to the abnormal head shape. The authors describe their experience with the use of intraoperative, preincision ultrasound localization of the lambda in patients with scaphocephaly undergoing a minimally invasive procedure. This simple technique can also be applied to other operations where proper identification of the cranial sutures is necessary.

Point of maximum width: a new measure for anthropometric outcomes in patients with sagittal synostosis. J Craniofac Surg 2015; 25:1226-9.

Abstract
The esthetic success of sagittal synostosis reconstruction is measured by cephalic index (CI). This limited measure does not fully account for the abnormal head shape in sagittal synostosis. In this retrospective study, we investigate a new objective measure, point of maximum width (PMW) of the skull from a vertex view, to determine where the head is widest for children with sagittal synostosis as compared with normal controls. Preoperative computed tomography (CT) scans of 27 children with sagittal synostosis and 14 postoperative CT scans at least 8 months after surgery were obtained. Normal CT scans were matched for age, sex, and race. Three-dimensional renderings were standardized for orientation. Mean (SE) PMW in patients with sagittal synostosis was 53% (1%) compared with 57% (1%) in controls (P < 0.001). Mean (SE) CI in patients with sagittal synostosis was 66.8% (0.8%) compared with 83.3% (1.0%) in controls (P < 0.001). The correlation between PMW and CI was weak in both controls (r2 = 0.002, P = 0.824) and uncorrected cases (r2 = 0.083, P = 0.145). After surgical correction, both CI and PMW significantly improved. Mean (SE) PMW in patients after surgical release of sagittal synostosis was 58% (1%) compared with 58% (1%) in controls (P = 0.986). The PMW is not a surrogate for CI but is a novel, valid measure of skull shape, which aids in quantifying the widest region of the skull. It is significantly more anterior in children with sagittal synostosis and exhibits a consistent posterior shift along the cranium after surgery, showing no difference compared with healthy children.

Abstract
OBJECTIVE To examine the impact of demographic factors, including insurance type, family income, and race/ethnicity, on patient age at the time of surgical intervention for craniosynostosis surgery in the US. STUDY DESIGN The Kids' Inpatient Database was queried for admissions of children younger than 3 years of age undergoing craniosynostosis surgery in 2009. Descriptive data regarding age at surgery for various substrata are reported. Multivariate regression was used to evaluate the effect of patient and hospital characteristics on the age at surgery. RESULTS Children with private insurance were, on average, 6.8 months of age (95% CI 6.2-7.5) at the time of surgery; children with Medicaid were 9.1 months old (95% CI 8.4-9.8). White children received surgery at mean age of 7.2 months (95% CI 6.5-8.0) and black and Hispanic children at a mean age of 9.1 months (95% CI 8.2-10.1). Multivariate regression analysis found Medicaid insurance (beta coefficient [B]=1.93, P<.001), black or Hispanic race/ethnicity (B=1.34, P=.022), and having 2 or more chronic conditions (B=2.86, P<.001) to be significant independent predictors of older age at surgery. CONCLUSION Public insurance and nonwhite race/Hispanic ethnicity were statistically significant predictors for older age at surgery, adjusted for sex, zip code median family income, year, and hospital factors such as size, type, region, and teaching status. Further research into these disparities is warranted.

Abstract
OBJECT Raised intracranial pressure (ICP) is recognized to occur in patients with nonsyndromic isolated sagittal craniosynostosis (SC) prior to surgery. However, the incidence of raised ICP following primary surgery is rarely reported and there appears to be a widely held assumption that corrective surgery for SC prevents the later development of intracranial hypertension. This study reports the incidence of postoperative raised ICP in a large cohort of patients with SC treated by 1 of 2 surgical procedures in a single craniofacial unit. METHODS A retrospective review was performed of all patients with SC who underwent either a modified strip craniectomy (MSC) or calvarial remodeling (CR) procedure under the care of the Oxford Craniofacial Unit between 1995 and 2010 and who were followed up for more than 2 years. The influence of patient age at surgery, year of surgery, sex, procedure type, and the presence of raised ICP preoperatively were analyzed. RESULTS Two hundred seventeen children had primary surgery for SC and were followed up for a mean of 86 months. The overall rate of raised ICP following surgery was 6.9%, occurring at a mean of 51 months after the primary surgical procedure. Raised ICP was significantly more common in those patients treated by MSC (13 of 89 patients, 14.6%) than CR (2 of 128 patients, 1.6%). Also, raised ICP was more common in patients under 1 year of age, the majority of whom were treated by MCS. No other factor was found to have a significant effect. CONCLUSIONS Postoperative raised ICP was found in more than 1 in 20 children treated for nonsyndromic SC in this series. It was significantly influenced by the primary surgical procedure and age at primary surgery. Careful long-term follow-up is essential if children who develop raised ICP following surgery are not to be overlooked.
