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.

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
With increasing interest in 3D photogrammetry, diverse methods have been developed for craniofacial shape analysis in craniosynostosis patients. This review provides an overview of these methods and offers recommendations for future studies. A systematic literature search was used to identify publications on 3D photogrammetry analyses in craniosynostosis patients until August 2023. Inclusion criteria were original research reporting on 3D photogrammetry analyses in patients with craniosynostosis and written in English. Sixty-three publications that had reproducible methods for measuring cranial, forehead, or facial shape were included in the systematic review. Cranial shape changes were commonly assessed using heat maps and curvature analyses. Publications assessing the forehead utilized volumetric measurements, angles, ratios, and mirroring techniques. Mirroring techniques were frequently used to determine facial asymmetry. Although 3D photogrammetry shows promise, methods vary widely between standardized and less conventional measurements. A standardized protocol for the selection and documentation of landmarks, planes, and measurements across the cranium, forehead, and face is essential for consistent clinical and research applications.

Abstract
BACKGROUND The diagnosis and management of metopic craniosynostosis involve subjective decision-making at the point of care. The purpose of this work was to describe a quantitative severity metric and point-of-care user interface to aid clinicians in the management of metopic craniosynostosis and to provide a platform for future research through deep phenotyping. METHODS Two machine-learning algorithms were developed that quantify the severity of craniosynostosis-a supervised model specific to metopic craniosynostosis [Metopic Severity Score (MSS)] and an unsupervised model used for cranial morphology in general [Cranial Morphology Deviation (CMD)]. Computed tomographic (CT) images from multiple institutions were compiled to establish the spectrum of severity, and a point-of-care tool was developed and validated. RESULTS Over the study period (2019 to 2021), 254 patients with metopic craniosynostosis and 92 control patients who underwent CT scanning between the ages of 6 and 18 months were included. CT scans were processed using an unsupervised machine-learning based dysmorphology quantification tool, CranioRate. The average MSS was 0.0 ± 1.0 for normal controls and 4.9 ± 2.3 ( P < 0.001) for those with metopic synostosis. The average CMD was 85.2 ± 19.2 for normal controls and 189.9 ± 43.4 ( P < 0.001) for those with metopic synostosis. A point-of-care user interface (craniorate.org) has processed 46 CT images from 10 institutions. CONCLUSIONS The resulting quantification of severity using MSS and CMD has shown an improved capacity, relative to conventional measures, to automatically classify normal controls versus patients with metopic synostosis. The authors have mathematically described, in an objective and quantifiable manner, the distribution of phenotypes in metopic craniosynostosis.

Abstract
The purpose of this study is to describe the treatment strategies and outcomes of nonsyndromic single-suture sagittal craniosynostosis based on the patient's age at intervention. Studies from MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials were systematically searched for patients with nonsyndromic single-suture sagittal craniosynostosis. Inclusion criteria encompassed studies with follow-up of at least 12 months, minimum of 25 patients per cohort, and first-time surgical intervention. The risk of bias in nonrandomized studies of intervention tool [Risk Of Bias In Non-randomized Studies-of Interventions (ROBINS-I)] was applied. A total of 49 manuscripts with 3316 patients met criteria. Articles were categorized based on age at intervention; 0 to 6, older than 6 to 12, and older than 12 months. Fifteen of the manuscripts described interventions in more than 1 age group. From the 49 articles, 39 (n=2141) included patients 0 to 6 months old, 15 (n=669) discussed patients older than 6 to 12 months old, and 9 (n=506) evaluated patients older than 12 months old. Follow-up ranged from 12 to 144 months. Over 8 types of open surgical techniques were identified and 5 different minimally invasive procedures were described. Minimally invasive procedures were exclusively seen in the youngest patient cohort, while open cranial vault reconstructions were often seen in the 2 older cohorts. Endoscopic surgery and open conservative procedures are indicated for younger patients, while complex open cranial vault reconstructions are common in older patients. However, there is no consensus on one approach over the other. Even with the analysis of this review, we cannot factor a strong conclusion on a specific technique.

Abstract
BACKGROUND AND OBJECTIVES Premature fusion of the sagittal suture is the most common form of craniosynostosis and can be treated using a variety of open or endoscopic approaches. Existing approaches have varying degrees of effectiveness. Open approaches, whether performed early or late, can be associated with significant blood loss and the need for transfusion. Endoscope-assisted approaches are minimally invasive but require months of postoperative helmet therapy to help remodel the skull. Implantation of springs or distractors requires a second operation for removal of the devices. Here, we present an alternative technique for early correction of sagittal craniosynostosis combining sagittal synostectomy with tension band sutures to remodel the skull without need for transfusion or helmet therapy. METHODS We retrospectively reviewed the medical records of all patients treated for sagittal craniosynostosis using a synostectomy with tension band sutures at a single tertiary care institution. Data on patient demographics, operative factors, and postoperative course were collected. RESULTS Thirty-four patients underwent the novel procedure. The median preoperative cephalic index was 68 and improved to 76 immediately postoperatively. The median blood loss was 10 mL while the operative duration was 112 minutes. No blood transfusions were needed. One small dural laceration was encountered that was promptly repaired. There were no postoperative complications. Patients presenting for follow-up visits showed continued improvement in head shape and cephalic index. CONCLUSION A modified sagittal craniectomy with tension band sutures to remodel the skull is effective in achieving immediate correction of sagittal craniosynostosis. The correction remains durable over long-term follow-up. Importantly, the technique can be performed with minimal blood loss and reduces transfusion risk, operative time, and overall morbidity compared with traditional open approaches while avoiding the need for helmet therapy necessitated by endoscopic approaches.

Abstract
OBJECTIVE To systematically review the published comparative aesthetic outcomes, and its determinants, for craniosynostoses surgically treated by minimally-invasive cranial procedures and open cranial vault remodeling (CVR). DESIGN PRISMA-compliant systematic review. SETTING Not-applicable. PATIENTS/PARTICIPANTS Articles were included if they compared spring cranioplasty, strip minimally-invasive craniectomy or CVR for outcomes related to aesthetics or head shape. Forty-two studies were included, comprising 2402 patients. INTERVENTIONS None. MAIN OUTCOME MEASURE(S) The craniometric and PROM used to determine surgical outcomes. RESULTS Twenty-five studies (59%) evaluated sagittal craniosynostosis, with metopic (7;17%) and unicoronal (4;10%) the next most prevalent. Thirty-eight studies (90%) included CVR, 24 (57%) included strip craniectomy with helmeting, 9 (22%) included strip craniectomy without helmeting, 11 (26%) included spring cranioplasty, and 3 (7%) included vault distraction. A majority of studies only used 1 (43%) or 2 (14%) craniometric measures to compare techniques. In sagittal synostosis, 13 (59%) studies showed no difference in craniometric outcomes, 5 (23%) showed better results with CVR, 3 (14%) with strip craniectomy, and 1 (5%) with springs. In studies describing other synostoses, 10/14 (71%) were equivocal. Subjective outcome measures followed similar trends. Meta-analysis shows no significant difference in cranial index (CI) outcomes between CVR and less invasive procedures in patients with sagittal synostosis. CONCLUSIONS There is no difference in CI outcomes between CVR and less invasive procedures. The majority of literature comparing craniometric and aesthetic outcomes between CVR and less invasive procedures shows equivocal results for sagittal synostosis. However, the heterogeneity of data for other craniosynostoses did not allow meta-analysis.

Abstract
Craniosynostosis is a craniofacial anomaly, characterized by premature fusion of one or more of the cranial sutures. Each suture and their combination correspond to a special type of deformation.Purpose. The study aimed at indicating the difficulties of early diagnostics of various forms of the craniosynostosis and evaluating the quality of treatment of patients with this disease depending on their age.Material and methods. A survey of parents with craniosynostosis who were treated at the Almazov National Medical Research Centre in 2018–2019 was conducted. The parents of 107 patients were surveyed. The main objectives of our research were: to evaluate the timeliness of diagnosis of craniosynostosis at primary health care at patient’s place of residence; to compare the methods of diagnosis verification and to present the results of the parents’ subjective assessment of the results of surgical treatment at the early and long-term postoperative period.Results. The median age of children when they were diagnosed with craniosystosis was 5 months, the median age of patients when they underwent a surgical treatment was 16 months. The median duration of the catamnesis was 6 months. We revealed that the preliminary diagnosis was established by a neurologist and pediatrician only in 21% of cases. Only at 28% of cases, children were directed to neurosurgeon, who confirm the diagnosis. In 38 (35.3%) cases, patient’s parents independently sought medical advice. The diagnosis was verified by the results of the computer tomography in 55% of patients. on because primary care specialists due to the lack of primary care specialists’ awareness about the diagnosis of craniosynostoses and attempts at long-term monitoring and conservative treatment. The timeliness of detection of craniosynostosis in the newborn period and in the|first month of life can significantly improve the cosmetic and functional outcomes of the disease.
