Review
INTRODUCTION
Craniofacial microsomia (CFM) is a complex congenital condition primarily affecting the ear, mandible, facial nerve and muscles, and tongue. Individuals with CFM are at increased risk of hearing loss, obstructive sleep apnea, and feeding/swallowing difficulties. The purpose of this scoping review was to summarize evidence pertaining to speech production in CFM.
METHOD
All articles reporting any characteristic of speech production in CFM were included and screened by two independent reviewers by title, abstract, and full text. Data charting captured details related to study population and design, CFM diagnostic criteria, speech outcome measurement, and key findings. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews checklist guided reporting of results. Our protocol was registered on the Open Science Framework (https://osf.io/npr94/) and published elsewhere.
RESULTS
Forty-five articles were included in the detailed review. Most articles originated from the United States, were published in the past decade, and utilized case report/series study design. A speech-language pathologist authored 29%. The prevalence of velopharyngeal insufficiency ranged from 19% to 55% among studies. Oral distortion of alveolar and palatal fricatives and affricates primarily characterized articulation errors. Studies identified increased disordered speech and lower intelligibility in adolescents with CFM compared to unaffected peers. Evidence pertaining to phonatory and respiratory speech findings is limited.
CONCLUSIONS
Evidence supports that individuals with CFM are at increased risk of both velopharyngeal and articulatory speech differences. Additional information is needed to develop speech screening guidelines for children with CFM. Heterogeneity in study design and outcome measurement precludes comparisons across studies.

OBJECTIVES
Treacher Collins syndrome (TCS) is a severe congenital mandibulofacial dysostosis that occurs one in every 50,000 births. The main clinical treatment of this rare disorder is reconstruction surgery. However, the high invasion, low security and long period of surgical intervention make it essential to explore prevention methods to decrease morbidity. The authors' aim is to summarize the prevention methods based on known mechanisms of TCS.
METHODS
A systematic review was conducted through an electronic search of PubMed, EMBASE and Web of Science databases through November 2019 using the following items: 'Treacher Collins syndrome OR TCS OR Franceschetti-Zwahlein-Klein syndrome OR Berry syndrome', 'gene therapy OR prevention'. Four causative gene names were also used. Articles which published in English language and explored the prevention methods for TCS were included and data concerning animal model, intervention, phenotype, conclusion were gathered.
RESULTS
Sixty-five studies were reviewed in total, and seven articles were included in this systematic review. Four articles used prevention methods related to the inhibition of p53, and three related to preclusion of oxidative stress-induced DNA damage.
CONCLUSIONS
This article provides a comprehensive review of the prevention methods for craniofacial abnormalities characteristic of TCS based on known pathogenesis in the current literatures. The craniofacial phenotype could be rescued through several treatment methods experimentally such as p53 inhibition and antioxidant administration.

BACKGROUND
The primary aim was to determine the clinical success rate after treatment for talocalcaneal (TCC) and calcaneonavicular coalitions (CNC). The secondary aim was to evaluate the complication, recurrence and revision rate.
METHODS
A search was carried out in MEDLINE, EMBASE and Cochrane Library. Methodological quality was assessed using the Methodological Index for Non-Randomised Studies (MINORS) criteria. The primary outcome was the clinical success rate and was pooled per type of coalition and treatment modality. 95% Confidence Intervals (CI) of the success rates were calculated. Secondary outcomes included complication rates, coalition recurrence rates, revision rates and pain improvement using the Visual Analogue Scale (VAS). A sub-analysis on interposition material was performed.
RESULTS
43 articles comprising of 1284 coalitions were included, with a pooled mean follow-up of 51 months. Methodological quality was fair. The overall pooled success rate for TCCs was 79% (95% CI, 75%-83%). Conservative treatment, open resection and arthroscopic resection of TCCs resulted in success rates of 58% (95% CI, 42%-73%), 80% (95% CI, 76%-84%) and 86% (95% CI, 71%-94%), respectively. CNCs have an overall success rate of 81% (95% CI, 75%-85%), with 100% (95% CI, 34%-100%), 80% (95% CI, 74%-85%) and 100% (95% CI, 65%-100%) for conservative treatment, open resection and arthroscopic resection, respectively. Pooled complication rates of 4% (95% CI, 3%-7%) for TCCs and 6% (95% CI, 4%-11%) for CNCs were found. The success rates of resection with and without interposition material for TCCs were 83% (95% CI, 78%-87%) and 79% (95% CI, 65%-88%), and for CNCs 81% (95% CI, 76%-86%) and 69% (95% CI, 44%-85%), respectively.
CONCLUSION
Treatment of tarsal coalitions can be considered good to excellent as well as safe, with an overall clinical success rate of 79% for TCCs and 81% for CNCs. Arthroscopic resection of the coalition appears to be non-inferior to open resection of TCCs and CNCs.

Meta-Analysis Review
Tranexamic Acid Demonstrates Efficacy without Increased Risk for Venous Thromboembolic Events in Cranial Neurosurgery: Systematic Review of the Evidence and Current Applications in Nontraumatic Pathologies.
BACKGROUND
The cautionary stance normally taken towards tranexamic acid (TXA) is rooted in concerns regarding its complication profile, namely its purported risk for venous thromboembolic events (VTEs). In the present review, we intend to bring increased attention to TXA as a remarkably valuable tool that does not appear to increase the risk for VTE when used as indicated in select patients.
METHODS
We queried three databases to identify reporting use of TXA during nontraumatic cranial neurosurgery procedures (excluded traumatic brain injury). Data gathered included VTE complications, deep venous thrombosis, use of allogeneic blood transfusions, estimated blood loss, and operative duration.
RESULTS
Twenty-eight studies were deemed eligible for inclusion in the present meta-analysis, including nine studies on surgical resection of intracranial neoplasms, ten studies on aneurysmal subarachnoid hemorrhage, and nine studies on craniosynostosis. In brain tumor surgery, TXA appears to successfully reduce blood loss without predisposing patients to VTE or seizure (P < 0.01). However, it does not appear to reduce rates of vasospasm in aneurysmal subarachnoid hemorrhage (P = 0.27), and its administration is not associated with clinically meaningful differences in long term neurological outcomes. For pediatric patients undergoing craniosynostosis procedures, TXA similarly reduces blood loss (P < 0.01). Nonetheless, low dosing protocols should be used because they appear effective and the effects of high dose TXA in children have not been studied.
CONCLUSIONS
TXA is an effective hemostatic agent that can be administered to reduce blood loss and transfusion requirements for a wide range of neurosurgical applications in a broad spectrum of patient populations.

Review
Hypoplastic asymmetry due to hemifacial microsomia (HFM) often represents the most difficult reconstruction in the craniomaxillofacial clinic. Although autogenous grafts are generally used for temporomandibular joint reconstruction (TMJR), the use of TMJR prostheses is not well established. The aim of this review was to identify, collect and analyse the use of extended TMJR (eTMJR) prostheses in patients with HFM, describing clinical features, surgical procedures and postoperative complications. Online searches of all major databases were performed according to PRISMA guidelines. All studies with HFM patients treated with the eTMJR prostheses were included. Descriptive statistics were used for data analysis. A total of 19 studies, including 08 case studies, 06 case series and 05 retrospective cohort studies, met the inclusion criteria, where a total of 42 HFM patients were reported from 18 countries, mostly from the United States (05; 26%). Fifteen of the 42 cases (~36%) were male. The mean ± SD (range) age of patients in all studies was 19.79 ± 5.81 (9-36) years. The mean ± SD (range) of patient follow-up was 41.30 ± 35.50 (6-136) months. A total of 5 (10.6%) patients were implanted with bilateral eTMJR prostheses. The Pruzansky classification was used in 18 (~89.5%) studies, OMENS classification in 01 (~5%) study, whereas no classification was reported in one study. Only 01 (7.1%) study had documented the eTMJR classification for the prosthesis used. In growing patients with or without a history of failed autogenous tissues, TMJR prostheses may provide a viable alternative. Randomized studies with large cohorts are warranted to validate these preliminary results.

Oculo-auriculo-vertebral spectrum (hemifacial microsomia/OAVS, OMIM #164210) is a heterogenous and congenital condition caused by a morphogenesis defect of the first and second pharyngeal arches. Etiology includes unknown genetic, environmental factors and chromosomal alterations, which 22q11.2 region is the most frequently reported. Several candidate genes for OAVS have been proposed; however, none has been confirmed as causative of the phenotype. This review aims to sum up all clinical and molecular findings in 22q region of individuals diagnosed with OAVS and to investigate genes that may be involved in the development of the spectrum. A search was performed in PubMed using all entry terms to OAVS and Chromosome 22q11. After screening, 11 papers were eligible for review. Deletions and duplications in the q11.2 region were the most frequent (18/22) alterations reported and a total of 68 genes were described. Our systematic review reinforces the hypothesis that 22q11 region is a candidate locus for OAVS as well as CLTCL1, GSC2, HIRA, MAPK1, TBX1, and YPEL1 as potential candidates genes for genotype-phenotype correlation. Complementary studies regarding genes interaction involved in the 22q11 region are still necessary in the search for a genotype-phenotype association, since the diagnosis of OAVS is a constant medical challenge.

Hallermann Streiff syndrome (HSS) is a rare congenital abnormality with about 200 case reports in the literature. Its etiology is unknown although it may be due to a sporadic mutation. Diagnosis is based on the association of craniofacial malformation, dental abnormalities, hypotrichosis, atrophy of the skin, proportionate nanism, congenital cataract and bilateral microphtalmos. Cranio-facial deformities are the main signs detected and the most easily recognizable. We report cranio-facial and oral signs from a systemic literature review, and illustrate our findings with two of our patients diagnosed with HSS. Common cranio-facial manifestations are craniofacial malformation with a « parrot beak » nose, micrognathia, aprominent skull, sutures closing anomaly, malocclusion, dental anomalies, eyebrows and eyelash lack and atrophy of the nose skin. Knowledge of these signs should allow for early diagnosis and adequate treatment and follow up.

Review
The study aimed to summarize current knowledge regarding the use of orthopaedic functional appliances (OFA) in managing unilateral craniofacial microsomia (UCM). The eligibility criteria for the review were (1) assessing use of OFA as a stand-alone treatment and (2) using OFA in combination during or after MDO. The PICO (population, intervention, comparison and outcome) format formulated clinical questions with defined inclusion and exclusion criteria. No limitations concerning language and publication year were applied. Information sources: A literature search of Medline, Scopus, Embase, Cochrane Central Register of Controlled Trials, Web of Science databases without restrictions up to 30 September 2022. The risk of bias was assessed. According to Cochrane and PRISMA guidelines, two independent authors conducted data extraction. The level of evidence for included articles was evaluated based on the Oxford evidence-based medicine database. Due to the heterogeneity of studies and insufficient data for statistical pooling, meta-analysis was not feasible. Therefore, the results were synthesized narratively. A total of 437 articles were retrieved. Of these, nine met inclusion criteria: five assessing OFA and four assessing OFA during or after MDO. There is limited evidence to suggest that stand-alone and combination treatment with OFA is beneficial for treating mild-to-moderate UCM-related dentofacial deformities in short term. No studies assessed the burden of care. In the management of UCM, there is insufficient evidence supporting the efficacy of OFA as a stand-alone treatment or when combined with MDO. Additionally, there is a lack of evidence regarding treatment protocols and the effect on the condyles and the TMJ. The study was registered at Prospero database number CRD42020204969.

Surgical correction of craniosynostosis can involve significant blood loss. Rates of allogenic blood transfusion have been reported to approach 100%. Multiple interventions have been described to reduce blood loss and transfusion requirements. The aim of this study was to analyze various approaches over the last 4 decades to optimize blood loss and management during craniosynostosis surgery. PRISMA guidelines for systematic reviews were followed. PubMed and Cochrane database searches identified studies analyzing approaches to minimizing blood loss or transfusion rate in craniosynostosis surgery. Primary outcomes included rate or amount of allogenic or autologous blood transfusion, estimated blood loss (EBL), postoperative hemoglobin (Hg), or hematocrit (Hct) levels. Secondary outcomes were examined when reported. Fifty-two studies met inclusion criteria. There was marked heterogeneity regarding design, inclusion criteria, surgical intervention, and endpoints. The majority of the studies were nonrandomized and noncomparative. Four studies analyzed erythropoietin (EPO), 6 analyzed various cell-saver (CS) technologies, 18 analyzed antifibrinolytics (tranexamic acid [TXA], aminocaproic acid [ACA], and aprotinin [APO]), 8 analyzed various alternatives, and 16 analyzed multimodal pathways & protocols. Some studies analyzed multiple approaches. Although the majority of studies reviewed represent level III/IV evidence, several high-quality level I studies were identified and included. Level I evidence supported an improvement in blood outcomes by utilizing EPO, CS, and TXA, individually or in concert with one another. Thus, this review suggests that a multi-prong approach may be the most effective means to optimize blood loss and transfusion outcomes in craniosynostosis surgery.

BACKGROUND
Primary craniosynostosis is a congenital craniofacial disorder in which cranial sutures prematurely close. Iatrogenic secondary stenosis is abnormal cranial suture closure caused by surgical manipulation of the suture. In contrast, idiopathic secondary stenosis develops in a suture that did not undergo surgical manipulation. The objective of this systematic review was to consolidate and characterize the incidence, classification, and management of idiopathic secondary stenosis in the literature.
METHODS
Literature from PubMed, Web Of Science, and EMBASE from 1970 to March 2022 was reviewed. The following information was extracted for individual patients: incidence of idiopathic secondary stenosis, index primary craniosynostosis, primary surgical correction, presenting signs of secondary stenosis, management, and further complications.
RESULTS
Seventeen articles detailing 1181 patients were included. Ninety-one developed idiopathic secondary stenosis (7.7%). Only 3 of these patients were syndromic. The most common index craniosynostosis was sagittal synostosis (83.5%). The most common suture undergoing idiopathic secondary stenosis was the coronal suture (91.2%). Patients presented at a median age of 24 months. The most common presenting sign was a radiologic finding (85.7%), although some patients presented with headache or head deformity. Only 2 patients, both syndromic, had complications following surgical correction of secondary stenosis.
CONCLUSIONS
Idiopathic secondary stenosis is a rare, long-term complication following index surgical repair of craniosynostosis. It can occur following any surgical technique. It most commonly affects the coronal suture but can affect any of the sutures, including pansynostosis. Surgical correction is curative in nonsyndromic patients.
