INTRODUCTION
Craniosynostosis, the premature fusion of ≥1 cranial sutures, is the leading cause of pediatric skull deformities, affecting 1 of every 2000 to 2500 live births worldwide. Technologies used for the management of craniofacial conditions, specifically in craniosynostosis, have been advancing dramatically. This article highlights the most recent technological advances in craniosynostosis surgery through a systematic review of the literature.
METHODS
A systematic electronic search was performed using the PubMed database. Search terms used were "craniosynostosis" AND "technology" OR "innovation" OR "novel.' Two independent reviewers subsequently reviewed the resultant articles based on strict inclusion and exclusion criteria. Selected manuscripts deemed novel by the senior authors were grouped by procedure categories.
RESULTS
Following review of the PubMed database, 28 of 536 articles were retained. Of the 28 articles, 20 articles consisting of 21 technologies were deemed as being novel by the senior authors. The technologies were categorized as diagnostic imaging (n = 6), surgical planning (n = 4), cranial vault evaluation (n = 4), machine learning (n = 3), ultrasound pinning (n = 3), and near-infrared spectroscopy (n = 1).
CONCLUSION
Multiple technological advances have impacted the treatment of craniosynostosis. These innovations include improvement in diagnosis and objective measurement of craniosynostosis, preoperative planning, intraoperative procedures, communication between both surgeons and patients, and surgical education.

Review
Constitutional disorders of bone, commonly termed skeletal dysplasias (SDs), are inherited disorders of cartilage and/or bone that affect their growth, morphometry and integrity. Associated skeletal abnormalities are usually but not invariably symmetrical. They may be classified as osteochondrodysplasias, which are conditions associated with abnormalities of the growth (dysplasias) or texture (osteodystrophy) of bone and/or cartilage, or dysostoses, which are conditions secondary to abnormal blastogenesis (occurring at or around the 6th week of in utero life). Skeletal involvement may also occur in other multisystem hereditary and acquired syndromes. The 2010 Nosology and Classification of Genetic Skeletal Disorders listed 456 conditions, of which approximately 50 are perinatally lethal, and 316 are associated with one or more of 226 genes. When an SD is suspected, a standard series of radiographs, collectively known as a skeletal survey, should be performed. The diagnosis of individual conditions is highly dependent on radiographic pattern recognition, which is achieved through a systematic review of the images and enhanced by discussion with colleagues and through the use of available tools, such as atlases and digital databases. This article summarises a systematic approach to the diagnosis of SDs, demonstrated using examples of some of the more common lethal and non-lethal conditions.

Review
Pfeiffer syndrome (PS) is a rare autosomal dominant craniofacial disorder characterized by primary craniosynostosis, midface hypoplasia, and extremities' abnormalities including syndactyly. The purpose of this article was to review the current knowledge regarding how PS affects the nervous system. Methodologically, we conducted a systematic review of the existing literature concerning involvement of the nervous system in PS. Multiple-suture synostosis is common, and it is the premature fusion and abnormal growth of the facial skeleton's bones that cause the characteristic facial features of these patients. Brain abnormalities in PS can be primary or secondary. Primary anomalies are specific developmental brain defects including disorders of the white matter. Secondary anomalies are the result of skull deformity and include intracranial hypertension, hydrocephalus, and Chiari type I malformation. Spinal anomalies in PS patients include fusion of vertebrae, "butterfly" vertebra, and sacrococcygeal extension. Different features have been observed in different types of this syndrome. Cloverleaf skull deformity characterizes PS type II. The main neurological abnormalities are mental retardation, learning difficulties, and seizures. The tricky neurological examination in severely affected patients makes difficult the early diagnosis of neurological and neurosurgical complications. Prenatal diagnosis of PS is possible either molecularly or by sonography, and the differential diagnosis includes other craniosynostosis syndromes. Knowing how PS affects the nervous system is important, not only for understanding its pathogenesis and determining its prognosis but also for the guidance of decision-making in the various critical steps of its management. The latter necessitates an experienced multidisciplinary team.

Review
PURPOSE
Posterior plagiocephaly (PP) is a common clinical condition in pediatric age. There are two main causes of PP: postural plagiocephaly and craniosynostosis. Early diagnosis is important, as it prevents neurological complications and emergencies. Diagnosis in the past was often made late and with imaging tests that subjected the infant to a high radiation load. Suture ultrasound does not use ionizing radiation; it is easy to perform, allows an early diagnosis, and directs toward the execution of the cranial 3D-CT scan, neurosurgical consultation, and possible intervention. The aim of the study is to describe the high sensitivity and specificity of suture ultrasound for the differential diagnosis between plagiocephaly and craniosynostosis.
METHODS
We reported our prospective experience and compared it with the data in the literature through a systematic review. The systematic review was conducted on electronic medical databases (PubMed, Embase, Cochrane Library, Scopus, and Web of Science) evaluating the published literature up to November 2020. According to Preferred Reporting Items for Systematic Reviews and Meta-ANALYSES (PRISMA statement), we identified 2 eligible studies. Additionally, according to AMSTAR 2, all included reviews have been critically rated as high quality. A total of 120 infants with abnormal skull shape were examined in NICU. All underwent clinical and ultrasound examination.
RESULTS
Of the total, 105 (87.5%) had plagiocephaly and 15 dolichocephaly/scaphocephaly (12.5%). None of these had associated other types of malformations and/or neurological disorders. The synostotic suture was identified ultrasonographically in 1 infant and subsequently confirmed by 3D CT scan (100%).
CONCLUSION
Cranial sutures ultrasonography can be considered in infants a selective, excellent screening method for the evaluation of skull shape deformities as first technique before the 3D CT scan exam and subsequent neurosurgical evaluation. Cranial suture ultrasonography should be considered part of clinical practice especially for pediatricians.

Review
INTRODUCTION
The standard of care in the treatment of symptomatic tarsal coalitions is open surgery. However, certain limitations exist with open surgery, which include limited visualization leading to an incomplete resection and possible recurrence of the tarsal coalition. Arthroscopic tarsal coalition resection (TCR) is an alternative that is gaining traction, primarily as the safety profile of posterior ankle and subtalar arthroscopy is more well understood. This study provides a systematic review of the outcomes of arthroscopic TCR.
METHODS
PubMed and Embase were searched independently by 2 reviewers for relevant articles based on predetermined criteria. The subject heading "tarsal coalition" and its related key terms were used.
RESULTS
A total of 416 studies were revealed by the initial search, out of which only 6 met our predetermined inclusion criteria. A total of 42 patients (average age: 17.6 years) were treated with arthroscopic TCR. Thirty-three (78.6%) and 9 (21.4%) patients had talocalcaneal and calcaneonavicular coalitions, respectively. The follow-up period ranged from 6 to 60 months (mean: 26 months), and no recurrence of the tarsal coalition was detected (0.0%). Complications occurred in two (4.8%) patients only, with one developing complex regional pain syndrome (CRPS), and another patient developing hyperesthesia on the medial aspect of the calcaneus.
CONCLUSION
Arthroscopic TCR is a feasible and effective surgery for both CNC and TCC with minimal complications and no disease recurrence at an average of 26 months follow-up. Future high-level of evidence studies are needed to compare the outcomes of open versus arthroscopic TCR.

Review
Rubinstein-Taybi syndrome (RTS) is a rare genetic syndrome associated with growth delay, phenotypic facial characteristics, microcephaly, developmental delay, broad thumbs, and big toes. Most research on RTS has focused on the genotype and physical phenotype; however, several studies have described behavioral, cognitive, social, and emotional characteristics, elucidating the behavioral phenotype of RTS. The reporting of this review was informed by PRISMA guidelines. A systematic search of CINAHL, Medline, and PsychINFO was carried out in March 2021 to identify group studies describing behavioral, cognitive, emotional, psychiatric, and social characteristics in RTS. The studies were quality appraised. Characteristics reported include repetitive behavior, behaviors that challenge, intellectual disability, mental health difficulties, autism characteristics, and heightened sociability. Findings were largely consistent across studies, indicating that many characteristics are likely to form part of the behavioral phenotype of RTS. However, methodological limitations, such as a lack of appropriate comparison groups and inconsistency in measurement weaken these conclusions. There is a need for multi-disciplinary studies, combining genetic and psychological measurement expertise within single research studies. Recommendations are made for future research studies in RTS.

Review
The aim of this systematic review was to review the literature on hearing impairment and ear anomalies in patients with craniofacial microsomia and to determine their prevalence. Sixty-two records including 5122 patients were included. Ear anomalies were present in 52-100% of patients. The most reported external ear malformations were microtia, pre-auricular tags, and atresia of the external auditory canal. Ossicular anomalies were the most reported middle ear malformations, whereas the most reported inner ear malformations included oval window anomalies, cochlear anomalies, and anomalies of the semicircular canals. Hearing loss in general was reported in 29-100% of patients, which comprised conductive hearing loss, mixed hearing loss, and sensorineural hearing loss. Between 21% and 51% of patients used hearing aids, and 58% underwent a surgical intervention to improve hearing. The relationship between different phenotypes of craniofacial microsomia and the type and severity of hearing loss is mostly unclear. In conclusion, the high prevalence of ear and hearing anomalies in patients with craniofacial microsomia underlines the importance of audiological screening in order to facilitate individual treatment.

Meta-Analysis Review
OBJECTIVE
Craniosynostosis leads to craniofacial deformity and may result in raised intracranial pressure, neurocognitive deficits, and psychosocial issues if left untreated. The global epidemiology of craniosynostosis is unknown. We conducted a meta-analysis to estimate global birth prevalence.
METHODS
PubMed, Embase, and Scopus were searched. Articles were screened by title and abstract and then full text. Meta-analysis of birth prevalence was conducted. Birth prevalence figures were combined with metrics detailing the number of births in 2019 to estimate the number of children worldwide born with craniosynostosis annually.
RESULTS
Of 1378 resultant articles, 24 studies were included, including 20 providing data for craniosynostosis overall and 9 for nonsyndromic craniosynostosis. World Health Organization regions of included studies were 9 (37.5%) European Region, 8 (33.3%) Region of the Americas, 4 (16.7%) Western Pacific region, 2 (8.3%) African Region, and 1 (4.2%) Eastern Mediterranean Region. Lower middle-income countries represented only 4% of study manuscripts. The overall birth prevalence of craniosynostosis was 5.9 per 10,000 live births (20 studies; 95% confidence interval [CI]: 3.9, 8.4; I = 100%). The birth prevalence of nonsyndromic craniosynostosis was 5.2 per 10,000 live births (9 studies; 95% CI: 3.4, 7.3; I = 98%). The number of children born globally with craniosynostosis in 2019 was estimated to be 84,665 (95% CI: 55,965, 120,540), including 72,857 (95% CI: 47,637, 120,280) with nonsyndromic craniosynostosis.
CONCLUSIONS
Craniosynostosis is a common condition that affects the neurocognitive and craniofacial skeletal development of children worldwide. Initiatives to scale up capacity for craniosynostosis epidemiologic research and clinical care are warranted, particularly in low- and middle-income countries.

Review
Craniofacial microsomia (CFM) is characterized by a heterogeneous underdevelopment of the facial structures arising from the first and second branchial arches, but extracraniofacial malformations such as vertebral anomalies also occur. This systematic review provides an overview of the literature on the types and prevalence of vertebral anomalies found in patients with CFM. A systematic search was conducted. Data on the number of patients, patient characteristics, types and prevalence of vertebral anomalies, and other associations between CFM and vertebral anomalies were extracted from the articles identified. Thirty-one articles were included. Seventeen articles described both the prevalence and types of vertebral anomalies in CFM, five articles described solely the types of vertebral anomalies in CFM, and nine articles reported solely the prevalence of vertebral anomalies in CFM. The vertebral anomalies most often reported in CFM are hemivertebrae, block vertebrae, scoliosis/kyphoscoliosis, and spina bifida. These anomalies are mostly present in the cervical and thoracic spine and ribs. The reported prevalence of vertebral anomalies in CFM varies from 8% to 79%. To diagnose vertebral anomalies early in patients with CFM, further research should focus on determining which patients with CFM are at risk of vertebral anomalies.

Review
Patients with craniofacial microsomia are at higher risk of developing obstructive sleep apnoea (OSA), as described in the previous article entitled "Obstructive sleep apnoea in craniofacial microsomia: a systematic review". These patients are also more likely to develop feeding difficulties. The present systematic review provides an overview of the literature on the prevalence, treatment, and follow-up of feeding difficulties in children with craniofacial microsomia (CFM). A search was performed in PubMed, Embase, Cochrane Library, and Web of Science for articles on CFM and feeding difficulties. The following data were extracted from the articles: number of patients, patient characteristics, presence of feeding difficulties, and the treatment and outcomes of feeding difficulties. Eight articles on CFM and feeding difficulties were included, two of which reported the prevalence of feeding difficulties (range 42-83%). Treatment mostly consisted of tube feeding. No information regarding follow-up was found in these articles. According to the literature, feeding difficulties are related to CFM. However, as there have been no prospective studies and few studies have presented objective measurements, no definitive conclusions can be drawn. Prospective studies are needed to determine the prevalence of feeding difficulties in patients with CFM.
