Minimally Invasive Strip Craniectomy Simplifies Anesthesia Practice in Patients With Isolated Sagittal Synostosis

Complication Rates and Cost of Endoscopic and Open Surgical Approaches to Management of Craniosynostosis: A Large, National, Inpatient Cohort Evaluation

To compare outcomes, complications, and costs between endoscopic and open surgical approaches in the management of craniosynostosis using a large national database.

Retrospective cohort study.

National Inpatient Sample database, including inpatient hospital discharge data from 2018 to 2021 across 48 states and Washington, D.C.

The present study included 1099 patients admitted with a primary diagnosis of craniosynostosis. Among them, 183 (16.6%) underwent endoscopic surgery and 916 (83.3%) underwent open surgery.

Surgical management of craniosynostosis, classified as either an endoscopic or open approach.

Length of hospital stay, total procedure costs, and rates of inpatient complications, including surgical and medical complications.

Endoscopic surgery was associated with a significantly shorter length of stay (mean 1.6 days vs 3.7 days, P < .001) and lower total costs ($ 66 815.90 vs $ 146 271.21, P < .001) compared to open procedures. It demonstrated lower rates of surgical complications (0.5% vs 7.9%, P < .001) and neurologic complications, primarily dural tears (0.5% vs 7.0%, P < .001). There were no differences in inpatient mortality between groups.

Endoscopic approaches to craniosynostosis offer advantages over open techniques, including reduced length of stay, costs, and complications. The present findings support the increasing adoption of endoscopic methods for craniosynostosis management. Future studies should assess the long-term impact on head shape durability and neurodevelopmental outcomes.

Clinical Reference Strategy for the Selection of Surgical Treatment for Nonsyndromic Sagittal Craniosynostosis: A Systematic Review and Network Meta-Analysis

OBJECTIVE

There is a lack of comprehensive comparative evidence regarding the effectiveness, intraoperative management, and safety of different surgical procedures for treating nonsyndromic sagittal synostosis. This study aims to evaluate existing clinical studies to provide evidence-based guidance for clinical practice.

METHODS

The authors performed a comprehensive search of 5 databases up to August 2024. Key outcomes included clinical effectiveness, measured by cephalic index (CI), and intraoperative management and safety indicators, such as intraoperative blood loss, operative time, and length of hospital stay. Direct and indirect effects, along with treatment rankings, were assessed using Bayesian pairwise and network meta-analysis models.

RESULTS

Fifteen studies with 1436 patients were included, and 4 network meta-analysis models were used to compare 5 surgical techniques: open strip craniectomy (OSS), calvarial vault remodeling (CVR), spring-mediated cranioplasty (SMC), endoscopic strip craniectomy (ESC), and endoscopic spring-mediated cranioplasty (ESMC). No significant differences in postoperative CI were found between the surgical methods. However, CVR was associated with significantly greater blood loss, longer operative time, and longer hospital stays compared with OSS, SMC, and ESC.

CONCLUSIONS

Current evidence does not demonstrate a clear superiority of one surgical method over another, with comparable treatment outcomes overall. However, CVR carries higher risks, and the choice of surgical approach should be individualized based on patient-specific factors and clinical judgment.

Total Cranial Vault Remodelling Versus Minimally Invasive Suturectomy With Postoperative Helmet Therapy in Sagittal Craniosynostosis

Different surgical techniques have been explored over time to treat children with scaphocephaly. The objective of this study is to compare morbidity and cosmetic outcomes in total cranial vault remodelling (TCVR) and minimally invasive suturectomy with postoperative helmet therapy (MISPH) in patients with scaphocephaly. The authors performed a retrospective comparative cohort study, including 43 patients with isolated sagittal craniosynostosis who underwent TCVR (n=17) or MISPH (n=26) at the Antwerp University Hospital between April 2008 and December 2022. MISPH was associated with significantly shorter procedure duration (TCVR 199 ± 48 min, MISPH 69 ± 12 min, P <0.001), decreased blood loss (TCVR 610 ± 298 mL, MISPH 85 ± 73 mL, P <0.001) and lower transfusion rate (TCVR 100%, MISPH 54%, P <0.001). Mean length of stay at the intensive care unit and the hospital were significantly shorter after MISPH (TCVR 6 ± 1 d, MISPH 3 ± 0.5 d). The change in CI after TCVR was significantly larger than after MISPH during the first postoperative year. However, the CI in the MISPH group was significantly higher during the first year compared with the TCVR group. Mean CI of the MISPH group reached normal limits during the first year, while in the TCVR group, mean CI reached normal values 5 years after surgery. The authors could not find a statistically significant difference in cosmetic outcome between the 2 groups. The authors conclude that MISPH is associated with decreased morbidity and comparable cosmetic results when compared with TCVR in the treatment of scaphocephaly.

Isolated Sagittal Craniosynostosis and Open or Endoscopic Cranial Vault Remodeling: An Evaluation of Developmental Outcomes

BACKGROUND

Craniosynostosis, a condition involving the premature fusion of cranial sutures, can impair brain development and potentially lead to developmental delays. This study compares open cranial vault remodeling versus endoscopic strip craniectomy treatment for isolated sagittal craniosynostosis, primarily focusing on development outcomes.

METHODS

A retrospective cohort study was conducted at a tertiary pediatric surgery center, involving all 45 patients treated surgically for isolated sagittal craniosynostosis from 2013 to 2024. Patients were categorized into 2 groups based on surgical intervention: open cranial vault remodeling (n=17) and endoscopic strip craniectomy (n=28). Data collected included patient demographics, intraoperative specifics, and postoperative outcomes. Developmental outcomes were assessed using postoperative progress notes.

RESULTS

Of the 45 patients, those undergoing open surgery were older (10.7 mo and 9.4 kg versus 3.3 mo and 6.4 kg, P<0.001) and experienced higher use of intraoperative drains (65% versus 0%, P<0.001), more prolonged procedures (189 versus 58 min, P<0.001), more significant blood loss (102 versus 62 mL, P=0.009), longer stays (3.3 versus 2.6 d, P=0.011), and higher opioid prescription rates (82% versus 43%, P=0.013) compared to the endoscopic group. Within 12 months postoperatively, social delays were more common in the open group (19 versus 0%, P=0.049), and, postoperatively in general, cognitive delays were more common in the open group (31% versus 4%, P=0.023) when compared to the endoscopic group.

CONCLUSIONS

Endoscopic cranial vault remodeling produces preferentially better hemodynamic, postoperative, and hospital stay outcomes. Although inferences into long-term developmental delay outcomes were limited due to sample size, a preferential benefit toward endoscopic intervention may exist.

Open versus endoscopic surgery with helmet molding therapy in non-syndromic patients with craniosynostosis: an updated systematic review and meta-analysis of clinical outcomes and treatment-related costs

OBJECTIVE

There is an ongoing debate regarding the optimal treatment for craniosynostosis as diverse factors influence the election between endoscopic and open surgery. Previous evidence favors endoscopic procedures. However, evidence remains unfulfilled by a limited number of patients and clustered in very few centers worldwide making it difficult to define it as a replicable technique in different populations. In recent years, evidence regarding endoscopic-assisted procedures has gone through a considerable spurt showing an increased interest among surgeons globally showing optimal outcomes in different populations and centers. In this systematic review and meta-analysis, we performed an updated analysis of previous reviews, including only non-syndromic patients. We also seek to provide a summary of the tendency of treatment observed in the literature. Similarly, this is the first study to include total costs within its analysis.

MATERIAL AND METHODS

Three previous meta-analyses published in 2018 yielded 11 eligible papers. We performed a systematic review and meta-analysis of the literature in MEDLINE and EMBASE databases through PubMed, Scopus, and Ovid to fill the gap of information between 2018 and 2024. Twenty-three total articles were included in the final analysis.

RESULTS

Variables analyzed were baseline characteristics, length of stay, blood loss, transfusion rates and volume, operative time, and costs. The analysis of data concluded a younger age at surgery in patients undergoing endoscopic surgery (p ≤0.00001). Blood loss, transfusion rates, and volumes depicted favored outcomes for endoscopy with less blood loss during surgery (p ≤0.00001), operative time (p ≤0.00001), and transfusion rates (p ≤0.00001) as well as lower transfused volumes (p ≤0.00001).

CONCLUSION

Endoscopic surgery carries fewer complications than open surgery. Treatment-related costs are highly decreased in endoscopic procedures after including costs related to outpatient care. Open surgery can be considered in older children if no endoscope or experienced surgeons in endoscopic procedures are available.

Initial UK series of endoscopic suturectomy with postoperative helmeting for craniosynostosis: early report of perioperative experience

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.

Novel Method of Lateral Vault Modification in Scaphocephaly

BACKGROUND

Scaphocephaly is the commonest from of craniosynostosis. There are several surgical methods to correct this and is influenced by the areas affected. A common thread in any of these corrections is an attempt to increase the biparietal diameter by modifying the lateral vault panel (LVP). A simple and novel method is proposed.

MATERIALS AND METHOD

The records of all patients undergoing scaphocephaly correction in the craniofacial unit at the institution were reviewed from 2003 to 2019. There were 106 patients, 57 males, and 49 females. The age ranged from 6 months to 5 years with a mean of 11 months. The method of vault remodeling was LVP only in 36 (34%), subtotal vault remodeling in 59 (56%), and total vault remodeling in 11 (10%). All 106 patients underwent LVP remodeling as part of the procedure. One or 2 wedge excisions was performed to increase the curvature of the LVP and this panel was fixed on the outside of the temporal squame bone.

RESULTS

The patients were followed up for a minimum of 1 year. Satisfactory results were obtained. The mean preoperative cephalic index was 64% and the mean postoperative index was 75%. There were minor complications such as screw visibility in a few patients.

CONCLUSIONS

Wedge excisions of the LVP is a simple and effective maneuver that can be used as strategy when performing scaphocephaly correction.

Public Perception of a Normal Head Shape in Children With Sagittal Craniosynostosis

: A question that remains unanswered is at what level of surgical correction does the public perceive a head shape to be "normal" or "acceptable?" For most cases of non-syndromic asymptomatic craniosynostosis, the parents desire for surgical correction is to improve the cosmetic appearance of head shape. At the time of this writing, the intraoperative surgeons' perspective of what constitutes an acceptable head shape is the target for surgical correction. In introducing an improved objectively cosmetic goal, an appropriate outcome measure would be to assess what the general public considers a normal or acceptable head shape in children with craniosynostosis.

METHOD

Twenty-two unique images were presented via an online crowdsourcing survey of a severe case of non-syndromic sagittal craniosynosis gradually corrected to an age and gender matched normalized head shape. Participants were recruited via the Sick Kids Twitter account. Participants were invited to rate the head shapes as "normal" or "abnormal."

RESULTS

The 538 participants completed the online survey. Participants were able to reliably and consistently identify normal and abnormal head shapes with a Kappa Score >0.775. Furthermore, participants indicated that a correction of 70% is required in order for the cranial deformity to be regarded as "normal." This threshold closely reflects a normal Cranial Index, which is a widely used morphometric outcome in craniosynostosis.

CONCLUSION

Crowdsourcing provides an ideal method for capturing the general population's perspective on what constitutes a normal and acceptable head shape in children with sagittal craniosynostosis. Laypersons are able to reliably and consistently distinguish cranial deformities from a "normal" head shape. The public indicates a threshold correction of 70% in sagittal craniosynosis to regard it as a "normal" head shape.

Endoscopic versus open approach in craniosynostosis repair: a systematic review and meta-analysis of perioperative outcomes

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.

Anesthesia for minimally invasive neurosurgery

PURPOSE OF REVIEW

With an ultimate aim of improving patients overall outcome and satisfaction, minimally invasive surgical approach is becoming more of a norm. The related anesthetic evidence has not expanded at the same rate as surgical and technological advancement. This article reviews the recent evidence on anesthesia and perioperative concerns for patients undergoing minimally invasive neurosurgery.

RECENT FINDINGS

Minimally invasive cranial and spinal surgeries have been made possible only by vast technological development. Points of surgical interest can be precisely located with the help of stereotaxy and neuronavigation and special endoscopes which decrease the tissue trauma. The principles of neuroanethesia remain the same, but few concerns are specific for each technique. Dexmedetomidine has a favorable profile for procedures carried out under sedation technique. As the new surgical techniques are coming up, lesser known anesthetic concerns may also come into light.

SUMMARY

Over the last year, little new information has been added to existing literature regarding anesthesia for minimally invasive neurosurgeries. Neuroanesthesia goals remain the same and less invasive surgical techniques do not translate into safe anesthesia. Specific concerns for each procedure should be taken into consideration.
