Most Efficient and Meaningful Patient-Reported Appearance Assessment in Different Cleft Types and Age Groups with CLEFT-Q.

BACKGROUND: The CLEFT-Q, a questionnaire developed and validated specifically for cleft patients, contains seven appearance scales. The International Consortium of Health Outcomes Measurement (ICHOM) has incorporated only some CLEFT-Q appearance scales in the Standard Set to minimize burden. This study evaluates which appearance scales provide the most meaningful information in the different cleft types at specific ages, for the most efficient cleft appearance outcome assessment. METHODS: Within this international multicenter study, outcomes of the seven appearance scales were collected, either as part of the ICHOM Standard Set, or as part of the field test study performed to validate the CLEFT-Q. Analyses were performed in separate age groups and cleft types, and involved univariate regression analyses, trend analyses, t tests, correlations, and floor and ceiling effects. RESULTS: A total of 3116 patients were included. Scores for most appearance scales showed a downward trend by age group, with the exception of the Teeth and Jaw scales. In all cleft types, several scales correlated strongly with each other. No floor effects were observed, but ceiling effects were found in several scales in different age groups, most often in the CLEFT-Q Jaw scale. CONCLUSIONS: A proposition for the most meaningful and efficient appearance outcome assessment in cleft patients is made. It was composed so that recommendations are of value for different cleft protocols and initiatives. Suggestions for the use of scales in the ICHOM Standard Set at different ages are given, and also from a clinical perspective. Use of the CLEFT-Q Scar, Lips, and Nose scales will provide additional relevant information.

Velopharyngeal insufficiency, speech, and language impairment in craniofacial microsomia: a scoping review.

This review provides a comprehensive overview of the literature on velopharyngeal insufficiency, associated anomalies, and speech/language impairment in patients with craniofacial microsomia (CFM). A systematic search of the literature was conducted to identify records on VPI and speech impairment in CFM from their inception until September 2022 within the databases Embase, PubMed, MEDLINE, Ovid, CINAHL EBSCO, Web of Science, Cochrane, and Google Scholar. Seventeen articles were included, analysing 1,253 patients. Velopharyngeal insufficiency results in hypernasality can lead to speech impairment. The reported prevalence of both velopharyngeal insufficiency and hypernasality ranged between 12.5% and 55%, while the reported prevalence of speech impairment in patients with CFM varied between 35.4% and 74%. Language problems were reported in 37% to 50% of patients. Speech therapy was documented in 45.5% to 59.6% of patients, while surgical treatment for velopharyngeal insufficiency consisted of pharyngeal flap surgery or pharyngoplasty and was reported in 31.6% to 100%. Cleft lip and/or palate was reported in 10% to 100% of patients with CFM; these patients were found to have worse speech results than those without cleft lip and/or palate. No consensus was found on patient characteristics associated with an increased risk of velopharyngeal insufficiency and speech/language impairment. Although velopharyngeal insufficiency is a less commonly reported characteristic of CFM than other malformations, it can cause speech impairment, which may contribute to delayed language development in patients with CFM. Therefore, timely recognition and treatment of speech impairment is essential.

Non-Surgical Respiratory Management in Relation to Feeding and Growth in Patients with Robin Sequence; a Prospective Longitudinal Study.

OBJECTIVE: To reflect upon our non-surgical respiratory management by evaluating clinical outcomes regarding airway, feeding, and growth during the first year of life in patients with Robin Sequence. DESIGN: Prospective study. SETTING: Sophia Children's Hospital, Rotterdam, the Netherlands. PATIENTS/ PARTICIPANTS: 36 patients with Robin Sequence who were treated between 2011 and 2021. INTERVENTIONS: Positional therapy and respiratory support. MAIN OUTCOME MEASURE(S): Data on respiratory outcomes included polysomnography characteristics and capillary blood gas values. Feeding outcomes were based on the requirement of additional tube feeding. Outcomes on growth were expressed as standard-deviation-scores (SDS) for weight-for-age (WFA) and height-for-age (HFA). RESULTS: Twenty patients were treated with positional therapy (PT), whilst the other 16 patients required respiratory support. Twenty-two patients presented with non-isolated Robin Sequence (RS). During the first year of life, obstructive apnea hypopnea index decreased, oxygen levels enhanced, and capillary blood gas values improved. Eighty-six percent (31/36) experienced feeding difficulties, which completely resolved in 71% (22/31) during their first year of life. From start treatment, to stop treatment, to the age of 1 year, the SDS WFA worsened from -0.40 to -0.33 to -1.03, respectively. CONCLUSIONS: Non-surgical respiratory treatment resulted in an improvement of respiratory outcomes to near normal during the first year of life in patients with RS. These patients often experience feeding difficulties and endure impaired weight gain up to 1 year of age, despite near normalization of breathing. The high prevalence of feeding difficulties and impaired weight for age indicate the urgency for early recognition and adequate treatment to support optimal growth.

Evaluation of Research Diagnostic Criteria in Craniofacial Microsomia.

Characteristics of patients with craniofacial microsomia (CFM) vary in type and severity. The diagnosis is based on phenotypical assessment and no consensus on standardized clinical diagnostic criteria is available. The use of diagnostic criteria could improve research and communication among patients and healthcare professionals. Two sets of phenotypic criteria for research were independently developed and based on multidisciplinary consensus: the FACIAL and ICHOM criteria. This study aimed to assess the sensitivity of both criteria with an existing global multicenter database of patients with CFM and study the characteristics of patients that do not meet the criteria. A total of 730 patients with CFM from were included. Characteristics of the patients were extracted, and severity was graded using the O.M.E.N.S. and Pruzansky-Kaban classification. The sensitivity of the FACIAL and ICHOM was respectively 99.6% and 94.4%. The Cohen's kappa of 0.38 indicated a fair agreement between both criteria. Patients that did not fulfill the FACIAL criteria had facial asymmetry without additional features. It can be concluded that the FACIAL and ICHOM criteria are accurate criteria to describe patients with CFM. Both criteria could be useful for future studies on CFM to create comparable and reproducible outcomes.

Three-dimensional dento-skeletal effects of mandibular midline distraction and surgically assisted rapid maxillary expansion: A retrospective study.

It was the aim of the study to provide a three-dimensional evaluation of dento-skeletal effects following bone-borne vs tooth-borne mandibular midline distraction (MMD) and tooth-borne surgically assisted rapid maxillary expansion (SARME). A retrospective observational study was conducted. Cone beam computed tomography (CBCT) records were taken pre-operatively (T1), immediately post-distraction (T2) and 1 year post-operatively (T3). All included 30 patients had undergone MMD (20 bone-borne MMD; 10 tooth-borne MMD). A total of 20 bone-borne MMD and 8 tooth-borne MMD patients had simultaneously undergone tooth-borne SARME. At T1 vs T3, canine (p = 0.007; 26.0 ± 2.09 vs 29.2 ± 2.02) and first premolar (p = 0.005; 33.8 ± 2.70 vs 37.0 ± 2.43) showed significant expansion on the tip level for tooth-borne MMD. This was no significant on the apex level, indicating tipping. Bone-borne MMD showed a parallel distraction gap, whereas tooth-borne MMD showed a V-shape. There was a significant (p = 0.017; 138 ± 17.8 vs 141 ± 18.2) inter-condylar axes increase for bone-borne MMD. In conclusion, bone-borne vs tooth-borne MMD and tooth-borne SARME showed stable dento-skeletal effects at 1 year post-operatively. Bone-borne and tooth-borne MMD seemed not to be superior to each other. The choice of distractor type therefore depends more on anatomical and comfort factors.

Establishing an International Interdisciplinary Research Network in Craniofacial Microsomia: The CARE Program.

OBJECTIVE: Craniofacial microsomia (CFM) is a broad clinical term used to describe a congenital condition most commonly involving the underdevelopment of the external ear, mandible, soft tissues, and facial nerve. Despite medical advances, understanding of the psychological health and healthcare experiences of individuals with CFM and their caregivers remains limited. This article describes a research program designed to address these knowledge gaps, and identify opportunities for psychosocial intervention and improved healthcare provision. DESIGN: The Craniofacial microsomia: Accelerating Research and Education (CARE) research program aims to: 1) Conduct up to 160 narrative interviews with individuals and caregivers to validate a conceptual framework; 2) Administer an online international survey of up to 800 individuals with CFM and caregivers to identify predictors of psychological distress; 3) Perform up to 60 semi-structured interviews with healthcare providers and advocacy leaders to examine the extent to which current healthcare provisions address identified patient needs; and 4) Establish a participant registry to build a longitudinal database and develop an international community. RESULTS: Teams in the USA and UK have been established, alongside an international, interdisciplinary Advisory Committee. Data analysis for Aim 1 is ongoing and informing the delivery of Aims 2-3. Aim 4 is also in development. A dedicated website serves as a recruitment tool, educational resource, and mechanism for engaging with the CFM community. CONCLUSIONS: The CARE program provides a comprehensive approach to understanding the experiences of individuals with CFM and their caregivers. Challenges encountered and lessons learned are shared for the benefit of the community.

A retrospective cohort study on dental implant survival in patients with grafted alveolar clefts.

OBJECTIVES: The aim of this study was to assess the survival rate of dental implants inserted in an alveolar cleft area where one or more bone graft procedures were performed and to identify possible factors that affect the survival rate. MATERIALS AND METHODS: The available data from 78 implants placed in 64 patients with grafted alveolar clefts were retrospectively analysed. Statistical analyses were performed using Kaplan-Meier survival analysis, log-rank tests and univariable Cox proportional hazard models. RESULTS: The median follow-up period from insertion to the last follow-up appointment was 46 months (IQR: 29-79.3). In five patients, a single implant failed. This resulted in a cumulative survival rate of 95.0% at median follow-up. The factors investigated in this study did not have a significant effect on implant survival. CONCLUSIONS: Dental implants placed in patients with alveolar clefts are a reliable treatment option for dental rehabilitation.

Upper and Lower Limb Anomalies in Craniofacial Microsomia and Its Relation to the OMENS+ Classification: A Multicenter Study of 688 Patients.

BACKGROUND: Craniofacial microsomia (CFM) is characterized by several malformations related to the first and second pharyngeal arch. Patients typically present with facial asymmetry, but extracraniofacial organ systems might be involved, including limb anomalies. The purpose of this study was to analyze the occurrence of upper and lower limb anomalies in CFM patients. Furthermore, the relation between limb anomalies and the OMENS+ (orbital distortion; mandibular hypoplasia; ear anomaly; nerve involvement; soft-tissue deficiency; and associated extracraniofacial anomalies) classification was examined. METHODS: A retrospective study was conducted including patients with CFM from craniofacial units in three different countries. Patients were included when clinical and/or radiographic images were available. Demographic, radiographic, and clinical information was obtained. RESULTS: A cohort of 688 patients was available and selected for analysis. In total, 18.2% of the patients were diagnosed with at least one upper and/or lower limb anomaly. Upper and lower limb anomalies were seen in, respectively, 13.4% and 7.8% of patients. Patients with other extracraniofacial anomalies had a significantly higher risk for limb anomalies (OR, 27.98; P = 0.005). Laterality of CFM and a higher OMENS score were not associated with limb anomalies. CONCLUSIONS: More than one in six patients with craniofacial microsomia have limb anomalies. Therefore, clinical awareness for these anomalies is warranted. Examination and, if present, follow-up on limb abnormalities in patients with CFM should be implemented in the standard assessment of CFM patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Optimizing the Psychosocial Function Measures in the International Consortium for Health Outcomes Measurement Standard Set for Cleft.

BACKGROUND: To ensure the feasibility of implementing PROMs in clinical practice, they must be continually appraised for undue burden placed on patients and clinicians and their usefulness for decision-making. This study assesses correlations between the CLEFT-Q psychosocial scales in the International Consortium for Health Outcomes Measurement Standard Set for cleft and explores their associations with patient characteristics and psychosocial care referral. METHODS: Spearman correlation coefficients were calculated for CLEFT-Q psychological function, social function, school function, face, speech function, and speech-related distress scales. Logistic regressions were used to assess the association of cleft phenotype, syndrome, sex, and adoption status on scale scores and clinical referral to psychosocial care for further evaluation and management. RESULTS: Data were obtained from 3067 patients with cleft lip and/or palate at three centers. Strong correlations were observed between social function and psychological function (r > 0.69) and school function (r > 0.78) scales. Correlation between school function and psychological function scales was lower (r = 0.59 to 0.68). Genetic syndrome (OR, 2.37; 95% CI, 1.04 to 5.41), psychological function (OR, 0.92; 95% CI, 0.88 to 0.97), school function (OR, 0.94; 95% CI, 0.90 to 0.98), and face (OR, 0.96; 95% CI, 0.94 to 0.98) were significant predictors for referral to psychosocial care. CONCLUSIONS: Because social function as measured by the CLEFT-Q showed strong correlations with both school and psychological function, its additional value for measuring psychosocial function within the Standard Set is limited, and it is reasonable to consider removing this scale from the International Consortium for Health Outcomes Measurement Standard Set for cleft.

Can Dynamic Magnetic Resonance Images Improve Prenatal Diagnosis of Robin Sequence.

BACKGROUND: Robin sequence (RS) is a triad of micrognathia, glossoptosis, and airway obstruction. Prenatal diagnosis of RS improves delivery planning and postnatal care, but the process for prenatal diagnosis has not been refined. The purpose of this study was to determine if dynamic cine magnetic resonance imaging (MRI) can improve the reliability of prenatal diagnosis for RS compared to current static imaging techniques. MATERIALS AND METHODS: This is a retrospective cross-sectional study including fetuses with prenatal MRIs obtained in a single center from January 2014 to November 2019. Fetuses were included if they: 1) had a prenatal MRI with cine dynamic sequences of adequate quality, 2) were live born, and 3) had postnatal craniofacial evaluation to confirm RS. Patients without postnatal confirmation of their prenatal findings were excluded. The primary predictor variable was imaging type (cine or static MRI). Outcome variables were tongue and airway measurements: 1) tongue height, 2) length and width, 3) tongue shape index, 4) observation of tongue touching the posterior pharyngeal wall, and 5) measurement of oropharyngeal space. All measurements were made independently on the cine images and on static MRI sequences for the same cohort of subjects by a pediatric radiologist. Data were analyzed using paired samples t tests and Fisher exact tests, and significance was set as P < .05. RESULTS: A total of 11 patients with RS were included in the study. The smallest airway space consistently demonstrated complete collapse on the cine series compared to partial collapse on static images (0 mm vs 1.7 ± 1.4 mm, P = .002). No other imaging variable was statistically significantly different between techniques. CONCLUSIONS: Cine imaging sequences on prenatal MRI were superior to static images in discerning complete collapse of the smallest airway space, an important marker of RS. This suggests a possible benefit to adding dynamic MRI evaluation for prenatal diagnosis of this condition.

The Accuracy of Computer-Assisted Surgical Planning in Predicting Soft Tissue Responses After Le Fort I Osteotomy: Retrospective Analysis.

PURPOSE: Mismatch between preoperative planning and surgical outcome in maxillofacial surgery relate to on-table replication of presurgical planning and predictive algorithm inaccuracy: software error was hereby decoupled from planning inaccuracy to assess a commercial software. The hypothesis was that soft tissue prediction error would be minimized if the surgical procedure was replicated precisely as planned and is independent of the extent of bone repositioning. MATERIALS AND METHODS: Cone-beam computed tomography scans of 16 Le Fort I osteotomy patients were collected at Boston Children's Hospital. Preoperative and postoperative models of bone and soft tissue were constructed and the maxilla repositioning was replicated. Each model was subdivided into 6 regions: mouth, nose, eyes, and cheeks. Soft tissue prediction (performed using Proplan CMF-Materialise) for each patient was compared with the relative postoperative reconstruction and error was determined. P <0.05 was considered significant. RESULTS: Le Fort I segment repositioning was replicated within 0.70±0.18 mm. The highest prediction error was found in the mouth (1.49±0.77 mm) followed by the cheeks (0.98±0.34 mm), nose (0.86±0.23 mm), and eyes (0.76±0.32). Prediction error on cheeks correlated significantly with mouth ( r =0.63, P < 0.01) and nose ( r =0.67, P < 0.01). Mouth prediction error correlated with total advancement ( r =0.52, P =0.04). CONCLUSIONS: ProPlan CMF is a useful outcome prediction tool; however, accuracy decreases with the extent of maxillary advancement even when errors in surgical replication are minimized.

Current Practice for Transverse Mandibular and Maxillary Discrepancies in the Netherlands: A Web-Based Survey Among Orthodontists and Oral and Maxillofacial Surgeons.

The main objective of this study was to provide an overview of the current practice for transverse mandibular and maxillary discrepancies in the Netherlands using a web-based survey. Orthodontists (ORTHO) and Oral and Maxillofacial Surgeons (OMFS) in the Netherlands were invited to the web-based survey via their professional association. Three cases were presented which could be treated non-surgically and surgically. Participants were asked what treatment they preferred: no treatment, orthodontic treatment with optional extractions or surgically assisted orthodontic treatment. The web-based survey ended with questions on various technical aspects and any experienced complication. Invitation was sent to all 303 members of professional association for ORTHO and to all 379 members of professional association for OMFS. Overall response number was 276 (response rate of 40.5%), including 127 incomplete responses. Generally, ORTHO prefer orthodontic treatment with optional extractions and OMFS lean towards surgically assisted orthodontic treatment. Mandibular Midline Distraction appears to be less preferred, possibly due to lack of clinical experience or knowledge by both professions despite being proven clinical stable surgical technique with stable long-term outcomes. There seems to be consensus on technical aspects by both professions, however, there are various thoughts on duration of consolidation period. Complications are mostly minor and manageable.

The effect of natural growth on chin point deviation in patients with unilateral craniofacial microsomia: A retrospective study.

This study aimed to investigate the potential progressiveness of mandibular asymmetry and to study factors that influence chin point deviation in patients with unilateral craniofacial microsomia (CFM). Paediatric patients with unilateral CFM with available radiologic imaging and medical photographs were included. Chin point deviation was measured on clinical photographs. A Jonckheere-Terpstra test and linear mixed model for repeated measurements assessed the relation of chin point deviation on natural growth, Pruzansky-Kaban score, and soft tissue score. A total of 110 patients were included. The linear mixed model showed no statistically significant changes of chin point deviation during growth (effect estimate -0.006°, 95% CI -0.04° to -0.03°, p = 0.74). A statistical significant relation between both the Pruzansky-Kaban and soft tissue score on chin point deviation was found (effect estimate -5.10°, 95% CI -6.45° to -3.75°, p ≤ 0.001 and effect estimate -3.42°, CI -5.86° to -0.98°, p ≤ 0.001, respectively). Within the limitations of the study it seems that craniofacial microsomia may be a non-progressive disorder, because chin point deviation did not change over time.

A decade of clinical research on clinical characteristics, medical treatments, and surgical treatments for individuals with craniofacial microsomia: What have we learned?

AIM: This article provides a review of a decade of clinical research studies on clinical features, medical interventions, and surgical interventions for individuals with craniofacial microsomia (CFM). We also provide recommendations for future clinical research. METHOD: A systematic search of literature was conducted in Embase and PubMed/MEDLINE Ovid. All publications from 2010 to 2020 that included at least 10 individuals with CFM were considered relevant for this study. RESULTS: A total of 91 articles were included. In the past decade, many new studies on CFM have been published providing more insight on the diagnosis and management of patients with CFM. This review encompasses findings on the clinical difficulties patients with CFM encounter, including the craniofacial and extracraniofacial characteristics of patients with CFM and its related clinical consequences on breathing, feeding, speech, and hearing. CONCLUSIONS: A considerable number of large multicenter studies have been published in recent years, providing new insights in the clinical consequences of CFM. The phenotypic variety between patients with CFM makes patient-specific treatment tailored to individual needs essential. The research and development of clinical care standards might be challenging because of the heterogeneity of CFM. Future research on clinical and patient-reported outcomes can help identify optimal treatment strategies. Cooperation between craniofacial centers, using uniform registration and outcome measurement tools, could enhance research and future care for these patients. LEVEL OF EVIDENCE: Level IV.

Growth patterns and shape development of the paediatric mandible - A 3D statistical model.

Background/aim: To develop a 3D morphable model of the normal paediatric mandible to analyse shape development and growth patterns for males and females. Methods: Computed tomography (CT) data was collected for 242 healthy children referred for CT scan between 2011 and 2018 aged between 0 and 47 months (mean, 20.6 ± 13.4 months, 59.9% male). Thresholding techniques were used to segment the mandible from the CT scans. All mandible meshes were annotated using a defined set of 52 landmarks and processed such that all meshes followed a consistent triangulation. Following this, the mandible meshes were rigidly aligned to remove translation and rotation effects, while size effects were retained. Principal component analysis (PCA) was applied to the processed meshes to construct a generative 3D morphable model. Partial least squares (PLS) regression was also applied to the processed data to extract the shape modes with which to evaluate shape differences for age and sex. Growth curves were constructed for anthropometric measurements. Results: A 3D morphable model of the paediatric mandible was constructed and validated with good generalisation, compactness, and specificity. Growth curves of the assessed anthropometric measurements were plotted without significant differences between male and female subjects. The first principal component was dominated by size effects and is highly correlated with age at time of scan (Spearman's r = 0.94, p < 0.01). As with PCA, the first extracted PLS mode captures much of the size variation within the dataset and is highly correlated with age (Spearman's r = -0.94, p < 0.01). Little correlation was observed between extracted shape modes and sex with either PCA or PLS for this study population. Conclusion: The presented 3D morphable model of the paediatric mandible enables an understanding of mandibular shape development and variation by age and sex. It allowed for the construction of growth curves, which contains valuable information that can be used to enhance our understanding of various disorders that affect the mandibular development. Knowledge of shape changes in the growing mandible has potential to improve diagnostic accuracy for craniofacial conditions that impact the mandibular morphology, objective evaluation, surgical planning, and patient follow-up.

Prevalence of Ocular Anomalies in Craniosynostosis: A Systematic Review and Meta-Analysis.

BACKGROUND: The aim of this study was to describe the ophthalmic abnormalities and their prevalence in craniosynostosis prior to craniofacial surgery. METHODS: A systematic search was conducted on Medline OVID, Embase, Cochrane, Google Scholar, Web of Science Core Collection. Inclusion criteria were English papers, children aged <18 years with non-syndromic and syndromic craniosynostosis, case reports, case series, and case-control studies. A system of domains was established consisting of an anatomic and functional ophthalmic domain. A meta-analysis of single proportions was carried out using random effects model and pooled mean proportions with 95% confidence intervals (CI) were calculated. RESULTS: Thirty-two papers analyzing 2027 patients were included. Strabismus was the most common anomaly in non-syndromic craniosynostosis: Horizontal strabismus was highest prevalent in unicoronal craniosynostosis (UCS) 19% (95% CI 9-32), followed by vertical strabismus 17% (95% CI 5-33). In syndromic craniosynostosis, horizontal strabismus was most prevalent in Crouzon syndrome 52% (95 CI 26-76), followed by Apert syndrome 50% (95% CI 42-58). Vertical strabismus was most prevalent in Saethre-Chotzen 60% followed by Muenke's syndrome 36%. Furthermore, astigmatism was the second most reported outcome in non-syndromic craniosynostosis and highest prevalent in UCS 35% (95% CI 21-51). In syndromic craniosynostosis, astigmatism was most frequently seen in Crouzon syndrome 43% (95% CI 22-65), followed by Apert syndrome 34% (95% CI 14-58). Moreover, in syndromic craniosynostosis, 5-40% had a decrease in visual acuity (VA) ≤ 0.3 LogMAR in the better eye and 11-65% had a VA ≤ 0.3 LogMAR in at least one eye. DISCUSSION: This review demonstrates the high prevalence of ocular anomalies in non-syndromic and syndromic craniosynostosis. A multidisciplinary and systematic approach is needed for the screening and optimal treatment of these conditions in a timely manner.

Reducing social anxiety in adolescents distressed by a visible difference: Results from a randomised control trial of a web-based intervention.

A visible difference to the face or body may challenge adolescents' adjustment and engagement in life activities, where some require psychosocial support. However, evidence is limited for whether existing interventions for this adolescent group reduce social or appearance-related distress. We therefore conducted a parallel-group, randomised control trial to evaluate the effectiveness of Young Person's Face IT, a self-guided web-based psychosocial intervention developed for adolescents with a visible difference who experience distress. Adolescents (N = 189, aged 11-18) from two countries (Norway and the Netherlands), were randomly allocated to an intervention group or care as usual (CAU). Outcomes were body esteem, social anxiety, perceived stigmatisation, and life disengagement. Compared with CAU, participants who completed Young Person's Face IT showed reductions in social anxiety symptoms (ηp2 = 0.06). No significant improvements were found for the other outcomes. This study endorses web-based psychosocial support in reducing social anxiety in adolescents distressed by a visible difference. Future studies are needed to confirm the effectiveness of Young Person's Face IT and to explore potential long-term effects.

Ocular and adnexal anomalies in Treacher Collins syndrome: a retrospective multicenter study.

BACKGROUND: Treacher Collins syndrome (TCS) is a rare craniofacial disorder characterized by bilateral hypoplasia of facial structures and periorbital, ocular, and adnexal anomalies. The purpose of this multicenter study was to report the prevalence of ocular and adnexal anomalies in TCS and to identify patients at risk for visual impairment. METHODS: The medical records of patients seen at four craniofacial centers were reviewed retrospectively. The following data were reported: primary and secondary ocular and adnexal anomalies, orthoptic and ophthalmological findings, and severity of TCS based on the facial deformity. RESULTS: A total of 194 patients were included, of whom 49.5% were examined by an ophthalmologist or optometrist. The mean age at the first visual acuity measurement was 6.96 ± 6.83 years (range, 1.50-47.08); at final measurement, 11.55 ± 10.64 years (range, 1.75-62.58). Primary ocular anomalies were reported in 98.5% of cases, secondary anomalies in 34.5%, strabismus in 27.3%, refractive errors in 49.5%, and visual impairment in 4.6%. We found no association between ocular anomalies and visual impairment or between the severity of TCS and ocular anomalies or visual impairment, except for an increased prevalence of secondary ocular anomalies in patients with more severe manifestations of TCS. CONCLUSIONS: Ocular anomalies were present in nearly all patients with TCS, even in mild cases.

Correlation between head shape and volumetric changes following spring-assisted posterior vault expansion.

The aim of the study was to investigate whether different head shapes show different volumetric changes following spring-assisted posterior vault expansion (SA-PVE) and to investigate the influence of surgical and morphological parameters on SA-PVE. Preoperative three-dimensional skull models from patients who underwent SA-PVE were extracted from computed tomography scans. Patient head shape was described using statistical shape modelling (SSM) and principal component analysis (PCA). Preoperative and postoperative intracranial volume (ICV) and cranial index (CI) were calculated. Surgical and morphological parameters included skull bone thickness, number of springs, duration of spring insertion and type of osteotomy. In the analysis, 31 patients were included. SA-PVE resulted in a significant ICV increase (284.1 ± 171.6 cm3, p < 0.001) and a significant CI decrease (-2.9 ± 4.3%, p < 0.001). The first principal component was significantly correlated with change in ICV (Spearman ρ = 0.68, p < 0.001). Change in ICV was significantly correlated with skull bone thickness (ρ = -0.60, p < 0.001) and age at time of surgery (ρ = -0.60, p < 0.001). No correlations were found between the change in ICV and number of springs, duration of spring insertion and type of osteotomy. SA-PVE is effective for increasing the ICV and resolving raised intracranial pressure. Younger, brachycephalic patients benefit more from surgery in terms of ICV increase. Skull bone thickness seems to be a crucial factor and should be assessed to achieve optimal ICV increase. In contrast, insertion of more than two springs, duration of spring insertion or performing a fully cut through osteotomy do not seem to impact the ICV increase. When interpreting ICV increases, normal calvarial growth should be taken into account.

Emotional and Behavioral Problems in Children With a Cleft Lip With or Without Palate or an Infantile Hemangioma.

OBJECTIVE: Life can be challenging for children with a visible difference due to a medical condition, and they might be at risk for emotional and behavioral problems. This study examines emotional and behavioral problems in children with a cleft lip with or without palate (CL ± P) or an infantile hemangioma (IH) in relation to the visibility of the condition, the presence of additional condition-related problems, and parental affect. SETTING: This cross-sectional study took place in an academic medical hospital in the Erasmus MC Sophia Children's Hospital, the Netherlands. PARTICIPANTS: A total of 309 parents (mean age = 40.34, 44.00% male) of 182 children with CL ± P and 48 parents (mean age = 39.21, 37.50% male) of 33 children with an IH completed questionnaires. Children were 1.5 to 12 years old. RESULTS: Parents reported fewer child emotional and behavioral problems compared to normative data. Problems reported were mainly related to learning difficulties and parent gender, while visibility of the condition had no significant influence. Parental negative affect was related to child internalizing problems. Parental positive affect was not related to any of the outcome measures. CONCLUSIONS: Parents reported fewer problems for their children compared to normative data. This is inconsistent with previous research, showing similar or worse scores for these children compared to peers. Our findings may be explained by a protective parenting style, a response shift in parents, or problems developing at a later point in life.
