Abstract
Background Oculoauriculovertebral Spectrum (OAVS) encompasses abnormalities on derivatives from the first and second pharyngeal arches including macrostomia, hemifacial microsomia, micrognathia, preauricular tags, ocular and vertebral anomalies. We present genetic findings on a three-generation family affected with macrostomia, preauricular tags and uni- or bilateral ptosis following an autosomal dominant pattern. Methods We generated whole genome sequencing data for the proband, affected parent and unaffected paternal grandparent followed by Sanger sequencing on 23 family members for the top 10 candidate genes: KCND2, PDGFRA, CASP9, NCOA3, WNT10A, SIX1, MTF1, KDR/VEGFR2, LRRK1, and TRIM2 We performed parent and sibling-based transmission disequilibrium tests and burden analysis via a penalized linear mixed model, for segregation and mutation burden respectively. Next, via bioinformatic tools we predicted protein function, mutation pathogenicity and pathway enrichment to investigate the biological relevance of mutations identified. Results Rare missense mutations in SIX1, KDR/VEGFR2, and PDGFRA showed the best segregation with the OAV phenotypes in this family. When considering any of the 3 OAVS phenotypes as an outcome, SIX1 had the strongest associations in parent-TDTs and sib-TDTs (p=0.025, p=0.052) (unadjusted p-values). Burden analysis identified SIX1 (RC=0.87) and PDGFRA (RC=0.98) strongly associated with OAVS severity. Using phenotype-specific outcomes, sib-TDTs identified SIX1 with uni- or bilateral ptosis (p=0.049) and ear tags (p=0.01), and PDGFRA and KDR/VEGFR2 with ear tags (both p<0.01). Conclusion SIX1, PDGFRA, and KDR/VEGFR2 are strongly associated to OAVS phenotypes. SIX1 has been previously associated with OAVS ear malformations and is co-expressed with EYA1 during ear development. Efforts to strengthen the genotype-phenotype co-relation underlying the OAVS are key to discover etiology, family counseling and prevention.

Abstract
Hemifacial microsomia (HFM) presents a complex congenital anomaly characterized by the asymmetric underdevelopment of facial structures, predominantly affecting the ear, mouth, and mandible on one side of the face. This case study examines the intricacies of HFM through the presentation of a 23-year-old female with congenital deformities of the left ear and mandibular hypoplasia. Clinical and radiological evaluations revealed significant facial malformations, including mandibular hypoplasia, left temporomandibular joint fusion, and maxillary abnormalities, confirming the diagnosis of HFM. Management of HFM necessitates a multidisciplinary approach involving otolaryngologists, maxillofacial surgeons, orthodontists, and audiologists to comprehensively address functional and aesthetic concerns. Early diagnosis and intervention, along with psychosocial support, are essential for optimizing outcomes and improving the quality of life for individuals with HFM.

Abstract
Goldenhar syndrome is a rare congenital disease, characterized by the malformation of craniofacial features, spine, and other organs. Its pathogenesis and impact on patients' quality of life (QoL) have not been fully elucidated as yet. Therefore, data of all patients with Goldenhar syndrome, who were treated at Hannover Medical School between 1997 and 2020, were analyzed. Forty-three patients were identified. Their medical records were carefully reviewed for data regarding their age, sex, demographics, Pruzansky classification, surgical history, and affected side. Goldenhar syndrome-associated medical conditions, therapeutic procedures, and the impact of disease on QoL were assessed. Their QoL was assessed using the Oral Health Impact Profile (OHIP)-14 questionnaire. The χ 2 test and Pearson correlation were performed for statistical evaluation. Female sex was positively correlated with OHIP outcomes, whereas male sex had a negative correlation with OHIP outcomes. Therefore, females had significantly worse QoL than males. No significant correlation was observed between the Pruzansky classification and QoL or between surgical history and QoL. Goldenhar syndrome is a rare disease that presents with varying severity. Hence, prospective studies are required to further investigate the impact of Goldenhar syndrome on the QoL.

Abstract
BACKGROUND Craniofacial microsomia (CM) is characterized by changes in the first and second branchial arches. It is a clinical condition whose etiology is still uncertain, but studies have shown that genetic, nutritional, and environmental factors can result in disorders of blastogenesis of the branchial arches. This study evaluates gestational aspects, focusing on possible risk factors associated with CM. METHODS This is a case-control study conducted with patients monitored at a medical genetics service and compared to a control group of patients without evidence of malformations, born in a mother and child hospital, both located in Porto Alegre, Southern Brazil. Mothers' data were obtained using questionnaires and by reviewing medical records. The sample consisted of 43 patients with CM (cases) and 129 patients without evidence of malformations (controls), paired by sex, totaling three controls for each case. Data analysis was performed using the two-tailed Fisher's exact test, Pearson's chi-square test, and the t-test. RESULTS We identified several factors associated with the development of CM, including the use of abortion methods by the mothers of these babies (p = .001), maternal diabetes (p = .009), advanced maternal age (p = .035), and a history of vaginal bleeding (p < .001). Furthermore, these patients exhibited a tendency to be born prematurely (p = .027), with low birth weight (p = .007), and lower Apgar scores (p = .003) when compared to healthy infants. Using a multivariate model, the use of abortion methods (p = .003) and vaginal bleeding (p = .032) remained independently associated with craniofacial microsomia. CONCLUSIONS We have identified several risk factors for the development of CM, including a propensity for premature birth, low birth weight, and respiratory difficulties. Additionally, women of advanced maternal age and/or those who used abortion methods and/or have diabetes have a higher risk of giving birth to a baby with CM. This information can be valuable in clinical practice, especially for the prevention of future cases.

[PMID: 37837667 PMCID: PMC10667787 DOI: 10.1016/j.ijscr.2023.108906] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 09/28/2023] [Accepted: 09/30/2023] [Indexed: 10/16/2023] Open
Abstract
INTRODUCTION AND IMPORTANCE Hemifacial microsomia (HFM) is a complex congenital facial anomaly characterized by a wide spectrum of clinical features, which encompass the facial skeleton and other organ systems. Currently, there is no evidence to suggest an association between Hemifacial Microsomia and vascular malformations, whether of the vertebral or any other kind. CASE PRESENTATION Reporting a case of a 12-year-old male diagnosed with Hemifacial Microsomia (HFM) and left Microtia. The patient had previously undergone left auricle reconstruction; however, unfortunately, the flap resulted in necrosis. In our next step, we intend to proceed with further reconstruction. Before this, we plan to perform CT angiography to identify viable flap options for effectively closing the auricular defect. During this evaluation, we identified an anomaly structure in the vertebral vascularization. CLINICAL DISCUSSION During the CT angiography, we found a vascular malformation in the vertebral region. This anomaly manifested as tortuosity in the left vertebral vein, with the diameter on the left side being larger than that on the right. Additionally, the diameter of the left internal jugular artery was found to be smaller than its counterpart on the right. The maxillary artery of the left side was larger than the right. Notably, there was an absence of a submental artery on the left side, and a hypoplasia of the left angularis artery was observed. CONCLUSION Hemifacial microsomia could be associated with other malformations. Despite the fact that vertebral artery anomaly is not considered common anomaly in HFM, it is mandatory to perform CT angiography before reconstructive surgery, considering the possibility of massive bleeding during the operation.

Abstract
Hemifacial microsomia (HFM) is a common congenital malformation of the craniofacial region, including mandibular hypoplasia, microtia, facial palsy and soft tissue deficiencies. However, it remains unclear which specific genes are involved in the pathogenesis of HFM. By identifying differentially expressed genes (DEGs) in deficient facial adipose tissue from HFM patients, we hope to provide a new insight into disease mechanisms from the transcriptome perspective. RNA sequencing (RNA-Seq) was performed with 10 facial adipose tissues from patients of HFM and healthy controls. Differentially expressed genes in HFM were validated by quantitative real-time PCR (qPCR). Functional annotations of the DEGs were analyzed with DESeq2 R package (1.20.0). A total of 1,244 genes were identified as DEGs between HFM patients and matched controls. Bioinformatic analysis predicted that the increased expression of HOXB2 and HAND2 were associated with facial deformity of HFM. Knockdown and overexpression of HOXB2 were achieved with lentiviral vectors. Cell proliferation, migration, and invasion assay was performed with adipose-derived stem cells (ADSC) to confirm the phenotype of HOXB2. We also found that PI3K-Akt signaling pathway and human papillomavirus infection were activated in HFM. In conclusion, we discovered potential genes, pathways and networks in HFM facial adipose tissue, which contributes to a better understanding of the pathogenesis of HFM.

Abstract
BackgroundOculo-auriculo-vertebral spectrum (OAVS) is the second most common cause of head and neck malformations in children after orofacial clefts. OAVS is clinically heterogeneous and characterised by a broad range of clinical features including ear anomalies with or without hearing loss, hemifacial microsomia, orofacial clefts, ocular defects and vertebral abnormalities. Various genetic causes were associated with OAVS and copy number variations represent a recurrent cause of OAVS, but the responsible gene often remains elusive.MethodsWe described an international cohort of 17 patients, including 10 probands and 7 affected relatives, presenting with OAVS and carrying a 14q22.3 microduplication detected using chromosomal microarray analysis. For each patient, clinical data were collected using a detailed questionnaire addressed to the referring clinicians. We subsequently studied the effects ofOTX2overexpression in a zebrafish model.ResultsWe defined a 272 kb minimal common region that only overlaps with theOTX2gene. Head and face defects with a predominance of ear malformations were present in 100% of patients. The variability in expressivity was significant, ranging from simple chondromas to severe microtia, even between intrafamilial cases. Heterologous overexpression ofOTX2in zebrafish embryos showed significant effects on early development with alterations in craniofacial development.ConclusionsOur results indicate that properOTX2dosage seems to be critical for the normal development of the first and second branchial arches. Overall, we demonstrated thatOTX2genomic duplications are a recurrent cause of OAVS marked by auricular malformations of variable severity.

Abstract
OBJECTIVE Alcohol is a recognized teratogen, and alcohol exposure increases the risk for hemifacial microsomia (HFM) of the fetus during maternal pregnancy. The present study aimed to explore potential mechanisms and verify hub genes of HFM associated with alcohol by bioinformatics methods. METHODS First, HFM and alcohol pathogenic genes were obtained. Thereafter, a protein-protein interactional (PPI) network was constructed. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses and molecular complex detection were performed by Metascape. Finally, we used the cytoHubba plugin to screen the hub genes. RESULTS A total of 43 HFM genes and 50 optimal alcohol candidate genes were selected. The PPI networks for pathogenic genes contained 93 nodes and 503 edges. Functional enrichment analysis largely focused on tissue formation and development. Two modules were identified from the PPI network, and 10 hub genes were screened out. The genes most relevant to alcohol-induced HFM pathogenesis included CTNNB1, TP53, MYC, HDAC1, and SOX2. CONCLUSIONS This study identified some significant hub genes, pathways, and modules of HFM related to alcohol by bioinformatics analyses. Our results suggest that the CTNNB1, TP53, MYC, HDAC1, and SOX B1 gene subfamilies may have played a major role in alcohol-induced HFM.

Abstract
BACKGROUND Owing to the complex clinical manifestations of hemifacial microsomia (HFM), multidisciplinary cooperation is required to achieve better therapeutic effects in terms of function and aesthetics. This study aimed to explore the efficacy of the expanded two-flap auricular reconstruction combined with mandibular distraction osteogenesis in the treatment of HFM. METHODS This surgical strategy was performed in three stages. In the first stage, the retroauricular skin was expanded with a tissue expander and a mandibular distraction device was installed. In the second stage, the traditional expanded two-flap method for auricular reconstruction was adapted, and the framework was fabricated with costal cartilage and wrapped with the expanded skin flap, retroauricular fascia flap, and full-thickness skin graft. In the final stage, the tragus and lobule were rebuilt, the concha cavity deepened, and the mandibular distraction device removed. RESULTS From January 2014 to November 2018, 166 HFM patients underwent auricular reconstruction with the expanded two-flap method and simultaneous mandibular extension in our hospital. The median follow-up period was 9.3 months. Of the 166 patients, 154 patients and their families were satisfied with the results, and only 16 patients experienced complications. CONCLUSIONS This three-stage technique of simultaneous auricular reconstruction and mandibular distraction osteogenesis is safe and effective in achieving facial symmetry, improving occlusal contact, shortening treatment course, and relieving patient's suffering, especially for HFM patients.

Abstract
Oculo-auriculo-vertebral spectrum (OAVS) is a developmental disorder characterized by anomalies mainly involving the structures derived from the first and second pharyngeal arches. The spectrum presents with heterogeneous clinical features and complex etiology with genetic factors not yet completely understood. To date, MYT1 is the most important gene unambiguously associated with the spectrum and with functional data confirmation. In this work, we aimed to identify new single nucleotide variants (SNVs) affecting MYT1 in a cohort of 73 Brazilian patients diagnosed with OAVS. In addition, we investigated copy number variations (CNVs) encompassing this gene or its cis-regulatory elements and compared the frequency of these events in patients versus a cohort of 455 Brazilian control individuals. A new SNV, predicted as likely deleterious, was identified in five unrelated patients with OAVS. All five patients presented hearing impairment and orbital asymmetry suggesting an association with the variant. CNVs near MYT1, located in its neighboring topologically associating domain (TAD), were found to be enriched in patients when compared to controls, indicating a possible involvement of this region with OAVS pathogenicity. Our findings highlight the genetic complexity of the spectrum that seems to involve more than one variant type and inheritance patterns.

Abstract
Craniofacial microsomia (CFM, OMIM%164 210) is one of the most common congenital facial abnormalities worldwide, but it's genetic risk factors and environmental threats are poorly investigated, as well as their interaction, making the diagnosis and prenatal screening of CFM impossible. We perform a comprehensive association study on the largest CFM cohort of 6074 samples. We identify 15 significant (P < 5 × 10-8) associated genomic loci (including eight previously reported) and decipher 107 candidates based on multi-omics data. Gene Ontology term enrichment found that these candidates are mainly enriched in neural crest cell (NCC) development and hypoxic environment. Single-cell RNA-seq data of mouse embryo demonstrate that nine of them show dramatic expression change during early cranial NCC development whose dysplasia is involved in pathogeny of CFM. Furthermore, we construct a well-performed CFM risk-predicting model based on polygenic risk score (PRS) method and estimate seven environmental risk factors that interacting with PRS. Single-nucleotide polymorphism-based PRS is significantly associated with CFM [P = 7.22 × 10-58, odds ratio = 3.15, 95% confidence interval (CI) 2.74-3.63], and the top fifth percentile has a 6.8-fold CFM risk comparing with the 10th percentile. Father's smoking increases CFM risk as evidenced by interaction parameter of -0.324 (95% CI -0.578 to -0.070, P = 0.011) with PRS. In conclusion, the newly identified risk loci will significantly improve our understandings of genetics contribution to CFM. The risk prediction model is promising for CFM prediction, and father's smoking is a key environmental risk factor for CFM through interacting with genetic factors.

[PMID: 33511179 PMCID: PMC7809674 DOI: 10.12998/wjcc.v9.i1.148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Revised: 10/12/2020] [Accepted: 11/04/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Hemifacial microsomia (HFM) is the second most common craniofacial congenital anomaly following cleft lip and palate. Because of the various phenotypic spectra and the severity of the deformity, a wide range of treatment approaches have been proposed. Recently, the surgery-first approach (SFA) was introduced to treat mild to moderate HFM, and it yielded a balanced facial appearance. The SFA not only promotes rapid improvement in facial aesthetics but also considerably reduces the overall treatment time.
CASE SUMMARY A female patient, aged 25 years old, sought orthodontic treatment with the chief complaint of dental and facial asymmetry. After a comprehensive physical examination and imaging analysis were performed, the patient was diagnosed with mild HFM that was primarily attributed to unilateral abnormal development of the maxilla-mandibular. The SFA was carried out to correct the skeletal deformity. The palatal suture was used as the midline of the maxilla in the surgical plan to center the maxilla, and the chin was also properly positioned to obtain a relatively symmetrical facial appearance. Four weeks after the surgery, the patient was referred for postsurgical orthodontics to decompensate the dentition and stabilize the occlusion. After 20 mo of treatment, all orthodontic appliances were removed. The posttreatment photographs of the patient and her smile confirmed good aesthetic and occlusal results.
CONCLUSION Mild HFM can be corrected by SFA, which not only promotes rapid improvement in facial aesthetics but also considerably reduces the overall treatment time.

Abstract
OBJECTIVE An increasing number of patients use social media for health-related information and social support. This study's objective was to describe the content posted on Facebook groups for individuals with microtia and/or craniofacial microsomia (CFM) and their families in order for providers to gain insight into patient and family needs and experiences to inform clinical care. METHODS Two months of posts, images, comments, and "like" responses from two Facebook groups in the US and the UK were recorded and analyzed using content analysis. A secondary analysis identified statements of emotion. RESULTS Posts (N = 254) had a total of 7912 "like" responses, 2245 comments, and 153 images. There were three categories of posts: seeking guidance (43%; 9 themes), promoting events/news (33%; 5 themes), and sharing experiences (24%; 3 themes). Across categories, 16% of posts had emotional content. Most comments were responding to posts seeking guidance, including medical care (20%), surgical care (9%), and hearing aids (5%). Promotional posts often aimed to increase CFM awareness. Posts sharing experiences were generally positive, with the highest number of "likes". CONCLUSIONS Facebook groups members frequently exchanged health-related information, suggesting value placed on input from other families and the convenience of seeking information online. Posts also promoted awareness and shared experiences. Clinical care implications include the need for easily accessible accurate and tailored CFM-related health education. Additionally, providers should demonstrate awareness of health information on social media and may address the potential emotional impact of CFM by facilitating access to resources for social support.

Abstract
This cross-sectional study aims to assess the influence of maternal smoking and alcohol consumption during pregnancy on the facial shape of non-syndromic English adolescents and demonstrate the potential benefits of using multilevel principal component analysis (mPCA). A cohort of 3755 non-syndromic 15-year-olds from the Avon Longitudinal Study of Parents and Children (ALSPAC), England, were included. Maternal smoking and alcohol consumption during the 1st and 2nd trimesters of pregnancy were determined via questionnaire at 18 weeks gestation. 21 facial landmarks, used as a proxy for the main facial features, were manually plotted onto 3D facial scans of the participants. The effect of maternal smoking and maternal alcohol consumption (average 1-2 glasses per week) was minimal, with 0.66% and 0.48% of the variation in the 21 landmarks of non-syndromic offspring explained, respectively. This study provides a further example of mPCA being used effectively as a descriptive analysis in facial shape research. This is the first example of mPCA being extended to four levels to assess the influence of environmental factors. Further work on the influence of high/low levels of smoking and alcohol and providing inferential evidence is required.

Abstract
OBJECTIVES Craniofacial microsomia (CFM) is a congenital condition that typically involves hypoplasia of the ear and jaw. It is often associated with adverse effects such as hearing loss and sleep-disordered breathing. There is little research on its etiology. METHODS We conducted a case-control study from maternal interview data collected from mothers of infants with and without CFM. The study included 108 children with and 84 children without CFM. Logistic regression with adjustment for demographic factors was used to evaluate associations between maternal exposures of interest and risk for CFM overall, as well as for different phenotypic sub-groups of children on the CFM spectrum. RESULTS We found a statistically significant association between diabetes mellitus (DM) and CFM (OR 4.01, 95% CI 1.6-10.5). The association was slightly attenuated after adjustment for BMI. Higher parity was also associated with increased risk for CFM (OR 2.0, 95% CI 1.0-4.0). Vitamin A consumption and/or liver consumption was associated with a 70% lower risk compared with non-users (OR 0.3, 95% 0.1-0.8). Maternal age at the time of pregnancy was not associated with CFM. CONCLUSIONS These analyses contribute evidence linking maternal DM with an elevated risk of having an infant with CFM, which is consistent with previous research and adds to the body of knowledge about the strength of this association. Further study is warranted to understand the potential mechanisms underlying the effect of DM in the developing embryo.

Abstract
BACKGROUND This study focused mainly on the safety and unexpected incidents of mandibular distraction osteogenesis in treating patients with hemifacial microsomia. METHODS Records of 71 patients with hemifacial microsomia treated by mandibular distraction osteogenesis from February of 2010 to March of 2015 were examined in this retrospective study. The modified mandibular osteotomy was conducted under the assistance of three-dimensional reconstruction, computer-aided design, and rapid prototyping technique. Distraction was conducted 4 to 7 days postoperatively at a frequency of 1 mm/day; moreover, the distractor was kept in place for 4 to 13 months after the first operation before it was removed. The scope of distraction ranged from 20 to 40 mm. All incidents encountered during and after the mandibular distraction process were documented in the medical records of patients. The patients were followed up for an average of 34.4 months after the second-stage operation. RESULTS The overall rate of incidents was 36.6 percent. Of them, minor incidents, which could be resolved with or without noninvasive therapy, were observed in 18.3 percent of all procedures in this series. Meanwhile, the rate of moderate incidents necessitating invasive therapy was reported to be 12.7 percent, whereas that of major incidents that could not be resolved with invasive therapy was 5.6 percent. CONCLUSIONS Mandibular distraction osteogenesis is a widely used procedure for treating patients with hemifacial microsomia. It is extremely important to be fully aware of a variety of incidents occurring during and after the surgical procedure to minimize the frequency of occurrence of such incidents.

Abstract
Hemifacial microsomia (HFM) is a common congenital malformation of the craniofacial region. There are 3 possible pathogenic models of HFM—vascular abnormality and hemorrhage in the craniofacial region, damage to Meckel’s cartilage, and the abnormal development of cranial neural crest cells—and the most plausible hypothesis is the vascular abnormality and hemorrhage model. These 3 models are interrelated, and none of them is completely concordant with all the variable manifestations of HFM. External environmental factors (e.g., thalidomide, triazene, retinoic acid, and vasoactive medications), maternal intrinsic factors (e.g., maternal diabetes), and genetic factors (e.g., the recently reported mutations in OTX2, PLCD3, and MYT1) may lead to HFM through ≥1 of these pathogenic processes. Whole genome sequencing to identify additional pathogenic variants, biological functional studies to understand the exact molecular mechanisms, and additional animal model and clinical studies with large stratified samples to elucidate the pathogenesis of HFM will be necessary. Small-molecule drugs, as well as CRISPR/CAS9-based genetic interventions, for the prevention and treatment of HFM may also be a future research hotspot.

Abstract
OBJECTIVES To determine whether infant cases with craniofacial microsomia (CFM) evidence poorer neurodevelopmental status than demographically similar infants without craniofacial diagnoses ("controls"), and to examine cases' neurodevelopmental outcomes by facial phenotype and hearing status. STUDY DESIGN Multicenter, observational study of 108 cases and 84 controls aged 12-24 months. Participants were assessed by the Bayley Scales of Infant and Toddler Development-Third Edition and the Preschool Language Scales-Fifth Edition (PLS-5). Facial features were classified with the Phenotypic Assessment Tool for Craniofacial Microsomia. RESULTS After adjustment for demographic variables, there was little difference in Bayley Scales of Infant and Toddler Development-Third Edition or Preschool Language Scales-Fifth Edition outcomes between cases and controls. Estimates of mean differences ranged from -0.23 to 1.79 corresponding to standardized effect sizes of -.02 to 0.12 (P values from .30 to .88). Outcomes were better among females and those with higher socioeconomic status. Among cases, facial phenotype and hearing status showed little to no association with outcomes. Analysis of individual test scores indicated that 21% of cases and 16% of controls were developmentally delayed (OR 0.68, 95% CI 0.29-1.61). CONCLUSIONS Although learning problems have been observed in older children with CFM, we found no evidence of developmental or language delay among infants. Variation in outcomes across prior studies may reflect differences in ascertainment methods and CFM diagnostic criteria.

Abstract
BACKGROUND The authors compared the IQ and academic achievement of adolescents with craniofacial microsomia (cases) and unaffected children (controls). Among cases, the authors analyzed cognitive functioning by facial phenotype. METHODS The authors administered standardized tests of intelligence, reading, spelling, writing, and mathematics to 142 cases and 316 controls recruited from 26 cities across the United States and Canada. Phenotypic classification was based on integrated data from photographic images, health history, and medical chart reviews. Hearing screens were conducted for all participants. RESULTS After adjustment for demographics, cases' average scores were lower than those of controls on all measures, but the magnitude of differences was small (standardized effect sizes, -0.01 to -0.3). There was little evidence that hearing status modified case-control group differences (Wald p > 0.05 for all measures). Twenty-five percent of controls and 38 percent of cases were classified as having learning problems (adjusted OR, 1.5; 95 percent CI, 0.9 to 2.4). Comparison of cases with and without learning problems indicated that those with learning problems were more likely to be male, Hispanic, and to come from lower income, bilingual families. Analyses by facial phenotype showed that case-control group differences were largest for cases with both microtia and mandibular hypoplasia (effect sizes, -0.02 to -0.6). CONCLUSIONS The highest risk of cognitive-academic problems was observed in patients with combined microtia and mandibular hypoplasia. Developmental surveillance of this subgroup is recommended, especially in the context of high socioeconomic risk and bilingual families. Given the early stage of research on craniofacial microsomia and neurodevelopment, replication of these findings is needed. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, II.

Abstract
Calvarial defects are common reconstructive dilemmas secondary to a variety of etiologies including traumatic brain injury, cerebrovascular disease, oncologic resection, and congenital anomalies. Reconstruction of the calvarium is generally undertaken for the purposes of cerebral protection, contour restoration for psychosocial well-being, and normalization of neurological dysfunction frequently found in patients with massive cranial defects. Current methods for reconstruction using autologous grafts, allogeneic grafts, or alloplastic materials have significant drawbacks that are unique to each material. The combination of wide medical relevance and the need for a better clinical solution render defects of the cranial skeleton an ideal target for development of regenerative strategies focused on calvarial bone. With the improved understanding of the instructive properties of tissue-specific extracellular matrices and the advent of precise nanoscale modulation in materials science, strategies in regenerative medicine have shifted in paradigm. Previously considered to be simple carriers of stem cells and growth factors, increasing evidence exists for differential materials directing lineage specific differentiation of progenitor cells and tissue regeneration. In this work, we review the clinical challenges for calvarial reconstruction, the anatomy and physiology of bone, and extracellular matrix-inspired, collagen-based materials that have been tested for in vivo cranial defect healing.

Abstract
OBJECTIVE A congenital craniofacial anomaly (CFA) is expected to impact upon several domains of psychological, emotional and social functioning, yet no recent reviews have comprehensively summarised the available literature. Further, existing reviews tend to draw upon literature in the field of cleft lip and palate, and do not give substantive attention to other types of CFAs. DESIGN A review of 41 papers published between January 2000 and March 2016 pertaining to psychological adjustment to CFAs. MAIN OUTCOME MEASURES Findings are presented according to key psychological domains: General Psychological Well-being, Quality of Life, Behaviour, Emotional Well-being, Social Experiences, Appearance, and Treatment-Related Experiences. RESULTS Current literature offers a contradictory picture of adjustment to CFAs. Psychological adjustment appeared to be comparable to norms and reference groups in approximately half of the papers related to non-syndromic CFAs, while more variation was found across domains among samples with syndromic CFAs. Associations were found between adjustment, physical health and cognitive function in several papers. The review identified a number of gaps in the literature, such as the inclusion of a wide range of diagnoses within research samples. CONCLUSIONS This review demonstrates the complexity of findings, both within and across domains, and highlights a number of methodological challenges.

Abstract
OBJECTIVE Examine stress levels of parents of children with hemifacial microsomia (HFM) and the relationship of parental stress to child characteristics and cognitive coping strategies. DESIGN Prospective cross-sectional study. PARTICIPANTS AND SETTING Parents with a child (age 3-19 years) with HFM (N = 31) were recruited through the Department of Orthodontics and the Craniofacial Center, Sophia-Erasmus Medical Center, Rotterdam, The Netherlands. Intervention and Outcome Measures: The adapted and shortened Dutch version of the parental stress index (NOSI-K) was used to measure parental stress, and the cognitive emotion-regulation questionnaire was used to measure cognitive coping strategies. Pearson correlations and a multiple regression analysis were performed. RESULTS The hierarchical multiple regression analysis showed associations between increased parental stress and learning difficulties and use of acceptance as a coping strategy. This suggests that problems other than the characteristic visual appearance of the child's face in HFM have a greater influence on parental stress. CONCLUSIONS Learning difficulties of the child with HFM and parental acceptance affect stress in parents with a child with HFM the most and are important in the search for a targeted tailoring of intervention for parents with high levels of parental stress.

Abstract
Goldenhar syndrome is a rare condition which is characterized by a multitude of anomalies involving craniofacial structures, vertebrae, internal organs and usually occurs unilaterally. The etiology of this syndrome is unclear since it varies genetically and is linked to a plethora of reasons. Herein, we report a case of Goldenhar syndrome with hemifacial microsomia and microtia along with systemic involvement which was clinically and radio-graphically assessed. Many classical signs of the syndrome were present in the patient along with few rare ones. The various aspects of this rare disease have been discussed with emphasis on timely diagnosis and multidisciplinary approach to manage it. HOW TO CITE THIS ARTICLE Goswami M, Bhushan U, Jangra B.

Abstract
This systematic review aimed to investigate the association between maternal smoking during pregnancy and birth defects in children. We performed an electronic search of observational studies in the databases ovid MEDLINE (1950 to April 2010), LILACS and SciELO. We included 188 studies with a total of 13,564,914 participants (192,655 cases). Significant positive associations were found between maternal smoking and birth defects in the following body systems: cardiovascular (OR: 1.11; 95%CI: 1.03-1.19), digestive (OR: 1.18; 95%CI: 1.07-1.30), musculoskeletal (OR: 1.27; 95%CI: 1.16-1.39) and face and neck (OR: 1.28; 95%CI: 1.19-1.37). The strength of association between maternal smoking and birth defects measured by the OR (95%CI) is significantly related to the amount of cigarettes smoked daily (χ2 = 12.1; df = 2; p = 0.002). In conclusion, maternal smoking during pregnancy is associated with congenital malformations in children and this association is dose-dependent.

Abstract
IMPORTANCE The Möbius sequence is a rare condition defined by the combination of congenital non-progressive facial and abducens nerve palsies. The etiology of the sequence is still unknown, but likely encompasses a group of heterogeneous disorders involving genetic maldevelopment of the brainstem, a fetal vascular insult and/or teratogen exposure. The clinical phenotype reported has expanded over the years, and may be associated with more extensive cranial nerve and oropharyngeal involvement, as well as limb defects. OBSERVATIONS We describe two cases of children presenting with unilateral Möbius syndrome associated with ipsilateral unilateral palatal weakness. Investigations failed to identified a clear underlying etiology, but both cases shared phenotypic features of other more common cranial facial disorders such as craniofacial microsomia and the velocardiofacial syndrome. CONCLUSION AND RELEVANCE These two cases highlight the clinical heterogeneity of the Möbius sequence. Although asymmetries are not uncommon, cases with strictly unilateral features are extremely rare, and as such these may represent a distinct subgroup that may pertain to a specific etiology. Although in many cases, evidence of an intrauterine vascular insult may be identified, a contributing genetic etiology should be considered, even in cases with strictly unilateral features. As such genes expressed in the developing rhombencephalon and its vasculature represent good candidates for future investigation.

Abstract
Goldenhar's syndrome is a rare condition which was described initially in the early 1950s. It is characterized by a combination of anomalies: dermal epibulbar cysts, auricular appendices and malformations of the ears. In 1963, Gorlin suggested the name, oculo-auriculo-vertebral (OAV) dysplasia for this condition and he also included vertebral anomalies as signs of this syndrome. The aetiology of this rare disease has not been fully understood, as it has shown itself to be variable genetically and to be caused due to unclear reasons. Here, we are reporting two cases of Goldenhar's syndrome, where almost all the classical signs of this rare condition were present.

Abstract
Oculo-auriculo-vertebral spectrum is a complex developmental disorder characterised mainly by anomalies of the ear, hemifacial microsomia, epibulbar dermoids and vertebral anomalies. The aetiology is largely unknown, and the epidemiological data are limited and inconsistent. We present the largest population-based epidemiological study to date, using data provided by the large network of congenital anomalies registries in Europe. The study population included infants diagnosed with oculo-auriculo-vertebral spectrum during the 1990-2009 period from 34 registries active in 16 European countries. Of the 355 infants diagnosed with oculo-auriculo-vertebral spectrum, there were 95.8% (340/355) live born, 0.8% (3/355) fetal deaths, 3.4% (12/355) terminations of pregnancy for fetal anomaly and 1.5% (5/340) neonatal deaths. In 18.9%, there was prenatal detection of anomaly/anomalies associated with oculo-auriculo-vertebral spectrum, 69.7% were diagnosed at birth, 3.9% in the first week of life and 6.1% within 1 year of life. Microtia (88.8%), hemifacial microsomia (49.0%) and ear tags (44.4%) were the most frequent anomalies, followed by atresia/stenosis of external auditory canal (25.1%), diverse vertebral (24.3%) and eye (24.3%) anomalies. There was a high rate (69.5%) of associated anomalies of other organs/systems. The most common were congenital heart defects present in 27.8% of patients. The prevalence of oculo-auriculo-vertebral spectrum, defined as microtia/ear anomalies and at least one major characteristic anomaly, was 3.8 per 100,000 births. Twinning, assisted reproductive techniques and maternal pre-pregnancy diabetes were confirmed as risk factors. The high rate of different associated anomalies points to the need of performing an early ultrasound screening in all infants born with this disorder.

Abstract
This review describes important aspects of the most commonly encountered craniofacial syndromes. The goal is to provide otolaryngologists and other health care providers with critical information necessary to manage these patients appropriately. The algorithm provided in this article should be helpful in guiding the treatment of craniofacial patients based on their unique otolaryngologic characteristics. The principles highlighted in the algorithm can be applied to other craniofacial syndromes not addressed here, including Pierre Robin sequence and Down syndrome.

Abstract
Hemifacial microsomia (OMIM164210) is a condition featuring unilateral ear anomalies and ocular epibulbar dermoids associated with unilateral underdevelopment of the craniofacial bony structures. Other associated anomalies have also been described, especially spinal malformations, and the term oculoauriculovertebral dysplasia spectrum (OVAS) was suggested to include the three predominant systems involved. Both genetic and environmental causes are implied in the pathogenesis of the syndrome, with a 3% recurrence rate according to reports of both vertical transmission and affected siblings. No specific gene was identified, albeit mutations in chromosome 10 and deficiencies of genes in the endothelin pathway in mice exhibited the same clinical features. We hereby describe the first case of prenatal diagnosis of spinal and rib malformations associated to hemifacial microsomia by means of 2-D and 3-D ultrasound in a 23-week fetus. The sonographic study depicted fetal scoliosis due to the presence of hemivertebrae, Sprengel's deformity of the left shoulder, ribs fusion, asymmetric ears with unilateral microtia, mandible unilateral hypoplasia as well as single umbilical artery and a 'golf ball' sign in the left ventricle of the heart. The diagnosis of OVAS was suggested and the family received proper genetic consultation. After termination of the pregnancy, the syndrome was confirmed by postmortem 3-D computed tomography study. In view of the grim outcome, prenatal death rate and high mortality and morbidity when three or more systems are involved, prenatal diagnosis and appropriate counseling are warranted.

Abstract
BACKGROUND There is uncertainty over whether maternal smoking is associated with birth defects. We conducted the first ever comprehensive systematic review to establish which specific malformations are associated with smoking. METHODS Observational studies published 1959–2010 were identified (Medline), and included if they reported the odds ratio (OR) for having a non-chromosomal birth defect among women who smoked during pregnancy compared with non-smokers. ORs adjusted for potential confounders were extracted (e.g. maternal age and alcohol), otherwise unadjusted estimates were used. One hundred and seventy-two articles were used in the meta-analyses: a total of 173 687 malformed cases and 11 674 332 unaffected controls. RESULTS Significant positive associations with maternal smoking were found for: cardiovascular/heart defects [OR 1.09, 95% confidence interval (CI) 1.02–1.17]; musculoskeletal defects (OR 1.16, 95% CI 1.05–1.27); limb reduction defects (OR 1.26, 95% CI 1.15–1.39); missing/extra digits (OR 1.18, 95% CI 0.99–1.41); clubfoot (OR 1.28, 95% CI 1.10–1.47); craniosynostosis (OR 1.33, 95% CI 1.03–1.73); facial defects (OR 1.19, 95% CI 1.06–1.35); eye defects (OR 1.25, 95% CI 1.11–1.40); orofacial clefts (OR 1.28, 95% CI 1.20–1.36); gastrointestinal defects (OR 1.27, 95% CI 1.18–1.36); gastroschisis (OR 1.50, 95% CI 1.28–1.76); anal atresia (OR 1.20, 95% CI 1.06–1.36); hernia (OR 1.40, 95% CI 1.23–1.59); and undescended testes (OR 1.13, 95% CI 1.02–1.25). There was a reduced risk for hypospadias (OR 0.90, 95% CI 0.85–0.95) and skin defects (OR 0.82, 0.75–0.89). For all defects combined the OR was 1.01 (0.96–1.07), due to including defects with a reduced risk and those with no association (including chromosomal defects). CONCLUSIONS Birth defects that are positively associated with maternal smoking should now be included in public health educational materials to encourage more women to quit before or during pregnancy.

Abstract
The purpose of this study is to clarify the confusing nomenclature and pathogenesis of Developmental Facial Paralysis, and how it can be differentiated from other causes of facial paralysis present at birth. Differentiating developmental from traumatic facial paralysis noted at birth is important for determining prognosis, but also for medicolegal reasons. Given the dramatic presentation of this condition, accurate and reliable guidelines are necessary in order to facilitate early diagnosis and initiate appropriate therapy, while providing support and counselling to the family. The 30 years experience of our center in the management of developmental facial paralysis is dependent upon a thorough understanding of facial nerve embryology, anatomy, nerve physiology, and an appreciation of well-recognized mishaps during fetal development. It is hoped that a better understanding of this condition will in the future lead to early targeted screening, accurate diagnosis and prompt treatment in this population of facially disfigured patients, which will facilitate their emotional and social rehabilitation, and their reintegration among their peers.

OBJECTIVE To determine whether preadolescent children with hemifacial microsomia (HFM) have higher risk of neurodevelopmental delays than unaffected control individuals. DESIGN Case-control follow-up study of neurodevelopment in children with and without HFM. SETTING Case individuals were originally recruited from 26 craniofacial centers across the United States and Canada, and controls were recruited through community pediatricians. PARTICIPANTS One hundred thirty-six children with HFM (cases) and 568 unaffected children (controls). Main Exposure History of HFM. MAIN OUTCOME MEASURES The Peabody Picture Vocabulary Test-Third Edition, the Beery-Buktenica Developmental Test of Visual Motor Integration-Fifth Edition, and the Academic Competence scales from the Child Behavior Checklist and the Teacher Report Form. RESULTS Children with HFM scored lower than controls on all measures (effect size = -0.27 to -0.45; P < .001 to P = .008). Compared with controls, cases were 2 to 3 times as likely to score in the at-risk range. Relative to controls, outcomes were worse for male cases and those whose mothers were 25 years or younger at the time of their birth. Cases with HFM plus other malformations had poorer outcomes, as did cases with hearing, vision, or speech impairments. CONCLUSIONS This is the first study, to our knowledge, to show that children with HFM have poorer neurodevelopmental outcomes than unaffected children, but further study using more detailed assessments is indicated. Clinically, the findings suggest that early neurodevelopmental screening is warranted for all children with HFM.

Abstract
OBJECTIVE To determine whether children with hemifacial microsomia (HFM) have higher risk for psychosocial problems than children without HFM. METHODS One hundred and thirty-six children with HFM (64% male, mean age = 6.9 years) were compared to 568 matched controls (50% male, mean age = 7.0 years) on parent and teacher measures of behavior problems and social competence, and teacher rankings of peer acceptance. RESULTS Parents of cases and controls reported similar levels of behavior problems and social competence. Teachers reported higher frequencies of internalizing problems, lower social competence and less peer acceptance for cases. Relative to controls, teacher-rated outcomes were worse for female cases, those with younger mothers at the time of birth, those with eye anomalies, and those with one or more malformations in addition to the core features of HFM. CONCLUSIONS This study provides the first evidence of relatively poor psychosocial outcomes among children with HFM.

Abstract
BACKGROUND Craniofacial microsomia is one of the most common conditions treated by craniofacial teams. However, research regarding the cause of this condition or the surgical outcomes of treatment is scant. This is attributable to the lack of diagnostic criteria and the wide phenotypic spectrum. Standardized description of the craniofacial malformations associated with craniofacial microsomia is a necessary first step for multicenter, interdisciplinary research into this complex condition. METHODS The authors used the previously published pictorial Orbit, Mandible, Ear, Nerve, and Soft tissue-Plus classification scheme to assign a phenotypic severity score to patients with craniofacial microsomia treated at the Craniofacial Center at Seattle Children's Hospital. The authors modified the tool based on feedback from multidisciplinary focus groups. The authors also developed a standardized photographic protocol to facilitate assessment of patients using two-dimensional images. RESULTS Feedback from focus groups was synthesized to create a phenotypic assessment tool for craniofacial microsomia based on the pictorial Orbit, Mandible, Ear, Nerve, and Soft tissue-Plus classification system. This tool allows for more comprehensive description of the phenotype of craniofacial microsomia and is found to be effective for clinical use within a multidisciplinary craniofacial team. In addition, the photographic protocol for patients with craniofacial microsomia allows for classification from a two-dimensional photographic database, thereby facilitating research using archived photographs. CONCLUSIONS The phenotypic assessment tool for craniofacial microsomia protocol provides a simple and standardized method for practitioners and researchers to classify patients with craniofacial microsomia. We anticipate that this tool can be used in multicenter investigational studies to evaluate the cause of this condition, its natural history, and comparative effectiveness research.
