Abstract
Children with isolated cleft of the lip and/or palate (iCL/P) have been shown to be at risk for impaired reading ability. Structural and functional neuroimaging studies have revealed subtle morphological and functional abnormalities correlated to cognition and reading ability. However, the integrity of white matter tracts and their potential relationship to reading performance in iCL/P is under-studied. The purpose of the present study was to evaluate white matter integrity related to cognition and reading skills among participants with and without iCL/P. Data from two cross-sectional, case/control studies with similar neuropsychological batteries and diffusion tensor imaging (DTI) protocols were combined. The final sample included 210 participants (ages 7 to 27 years). Group and sex differences in fractional anisotropy (FA) values were examined between participants with (n = 105) and without (n = 105) iCL/P. Potential associations between FA values and age, cognition, and reading skills were also evaluated separately by group and sex. Sex effects were prominent in association and projection fibers, and effects of cleft status were found in association fibers and cerebellar regions, with isolated associations to reading skills. Findings provide preliminary understanding of microstructural associations to cognitive and reading performance among children, adolescents, and young adults with iCL/P.

Cognitive functioning and clinical characteristics of children with non-syndromic orofacial clefts: A case-control study. Front Psychol 2023; 14:1115304.

Abstract
Introduction The higher rate of neuropsychiatric disorders in individuals with non-syndromic orofacial clefts has been well documented by previous studies. Our goal was to identify children with non-syndromic orofacial clefts that are at risk for abnormal neurodevelopment by assessing their developmental history and present cognitive functioning. Materials and methods A single-center, case-controlled study was carried out at the Department of Pediatrics of the University of Pécs in Hungary. The study consisted of three phases including questionnaires to collect retrospective clinical data and psychometric tools to assess IQ and executive functioning. Results Forty children with non-syndromic oral clefts and 44 age-matched controls participated in the study. Apgar score at 5 min was lower for the cleft group, in addition to delays observed for potty-training and speech development. Psychiatric disorders were more common in the cleft group (15%) than in controls (4.5%), although not statistically significant with small effect size. The cleft group scored lower on the Continuous Performance Test. Subgroup analysis revealed significant associations between higher parental socio-economic status, academic, and cognitive performance in children with non-syndromic orofacial clefts. Analyzes additionally revealed significant associations between early speech and language interventions and higher scores on the Verbal Comprehension Index of the WISC-IV in these children. Discussion Children with non-syndromic orofacial clefts seem to be at risk for deficits involving the attention domain of the executive system. These children additionally present with difficulties that affect cognitive and speech development. Children with non-syndromic orofacial clefts show significant skill development and present with similar cognitive strengths as their peers. Longitudinal studies with larger sample sizes are needed to provide more conclusive evidence on cognitive deficits in children with non-syndromic orofacial clefts at risk for neurodevelopmental difficulties.

Abstract
Background Neuroimaging of individuals with non-syndromic oral clefts have revealed subtle brain structural differences compared to matched controls. Previous studies strongly suggest a unified primary dysfunction of normal brain and face development which could explain these neuroanatomical differences and the neuropsychiatric issues frequently observed in these individuals. Currently there are no studies that have assessed the overall empirical evidence of the association between oral clefts and brain structure. Our aim was to summarize the available evidence on potential brain structural differences in individuals with non-syndromic oral clefts and their matched controls. Methods MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Web of Science and Embase were systematically searched in September 2020 for case-control studies that reported structural brain MRI in individuals with non-syndromic oral clefts and healthy controls. Studies of syndromic oral clefts were excluded. Two review authors independently screened studies for eligibility, extracted data and assessed risk of bias with the Newcastle-Ottawa Scale. Random effects meta-analyses of mean differences (MDs) and their 95% confidence intervals (95% CI) were performed in order to compare global and regional brain MRI volumes. Results Ten studies from 18 records were included in the review. A total of 741 participants were analyzed. A moderate to high risk of bias was determined for the included studies. The cerebellum (MD: -12.46 cm3, 95% CI: -18.26, -6.67, n = 3 studies, 354 participants), occipital lobes (MD: -7.39, 95% CI: -12.80, -1.99, n = 2 studies, 120 participants), temporal lobes (MD: -10.53 cm3, 95% CI: -18.23, -2.82, n = 2 studies, 120 participants) and total gray matter (MD: -41.14 cm3; 95% CI: -57.36 to -24.92, n = 2 studies, 172 participants) were significantly smaller in the cleft group compared to controls. Discussion There may be structural brain differences between individuals with non-syndromic oral clefts and controls based on the available evidence. Improvement in study design, size, methodology and participant selection could allow a more thorough analysis and decrease study heterogeneity.

Abstract
The present study evaluated brain development in persons with isolated cleft lip and/or cleft palate (iCL/P) compared to unaffected controls using an accelerated longitudinal design. A sample of 134 males and females, ages 7-27 years, with iCL/P (184 observations, total) was compared to 144 unaffected controls (208 evaluations, total) on Wechsler Index scores and volumetric data from structural MRI scans. Boys with isolated cleft palate had verbal IQ 15.5 points lower than perceptual IQ; a clinically significant difference. Participants with iCL/P had differential growth trajectories of regional cerebrum matter and consistently lower volumes of cerebellar gray matter and subcortical matter.

Abstract
Background: The purpose of this study was to evaluate brain structure and function in participants with iCL/P and unaffected controls. Effects of cleft presence and reading status (average vs impaired) were evaluated.Methods: Males, ages 8-11 years old, including 26 with iCL/P and 57 unaffected peers were recruited and coded for reading status (average vs impaired). All participants underwent a volumetric and task-based functional MRI. Volumes and significant regions of activation during the decoding task were obtained. Main effects of cleft and reading status, and their interaction were evaluated.Results: Participants with iCL/P had significantly increased frontal gray matter volume (associated with average reading) and occipital gray and white matter volume (associated with impaired reading). Impaired readers with iCL/P had a distinctive activation pattern in visual association and motor regions relative to other groups.Conclusions: Findings suggest that increases in frontal gray matter volume may be associated with effective compensation during reading, while posterior increases in occipital volume may be associated with ineffective compensation for participants with iCL/P. These patterns were different from idiopathic dyslexia. Further work in a larger sample is needed to determine if these differences are associated with cleft type and with sex.Abbreviations: iCL/P (isolated cleft lip and/or palate); iCL (isolated cleft lip only); iCLP (isolated cleft lip and palate); iCP (isolated cleft palate only); uAR (unaffected average reader); uIR (unaffected impaired reader); cAR (average reader with iCL/P); cIR (impaired reader with iCL/P).

Abstract
OBJECTIVE The purpose of this study was to evaluate possible relationships between number of surgeries and parent ratings of academic functioning among children with isolated oral clefts. DESIGN Multicenter, retrospective cohort study including structured interviews, questionnaires, and chart reviews. SETTING Completion of questionnaires occurred during clinical visits at 6 different cleft centers across North America. PARTICIPANTS Parents of 285 children with isolated clefts of the lip and/or palate, aged 8 to 10 years old, participated in structured interviews and completed questionnaires regarding the academic and behavioral functioning of their children. MAIN OUTCOME MEASURES Parent interview and medical chart review of number of surgeries to date and parent ratings on the Adaptive Behavior Assessment System, Third Edition-Functional Academics Scale (ABAS-FA) and Child Behavior Checklist (CBCL) Total Competency Scale. RESULTS Parent ratings of ABAS-FA were at or above normative expectations, while ratings across CBCL Competency Scales were lower than normative expectations. Socioeconomic status (SES), age, and race were consistent predictors of parent ratings (higher SES, older age, and Caucasian race were associated with better functioning). Number of surgeries did not add significantly to academic ratings but did significantly contribute to ratings of social and activity participation. Patients with more surgeries were rated with lower functioning in these domains. CONCLUSIONS Findings do not support a connection between number of surgeries and later ratings of academic functioning but do support a connection to social and activity involvement. Recommendations for conducting direct studies of the connection between surgeries and academic functioning as well as clinical considerations for surgeries and impact on social and activity involvement are discussed.
