Objective: Our goal was to compare data collected from 3- and 7-day Infant with Clefts Observation Outcomes (iCOO) diaries.

Design: Secondary data analysis of an observational longitudinal cohort study. Caregivers completed the daily iCOO for 7 days before cleft lip surgery (T0) and for 7 days after cleft lip repair (T1).

Objective: To evaluate the sensitivity to change of daily ratings of the comfort (COMF) and behavioral/emotional health (BEH) domains of the Infants with Clefts Observation Outcomes Instrument (iCOO) at 3 time points, and to assess the association of post-surgical interventions on iCOO ratings.

Design: The COMF and BEH domains were completed by caregivers before (T0), immediately after (T1), and 2-months after (T2) cleft lip (CL) surgery. Analyses included descriptive statistics, correlations, -tests, and generalized estimating equations.

This observational, multisite cohort study explored health-related quality of life (HRQoL) in children with cleft lip and/or palate (CL/P), including interrater agreement and ratings for this group relative to clinical cutoff scores and published means for healthy and chronically ill children. Participants (338 children ages 8-10 years, 45.9% male and their parents, 82.

Caregiver and observer-reported measures are frequently used as outcomes for research on infants and young children who are unable to report on their own health. Our team developed the Infant with Clefts Observation Outcomes Instrument (iCOO) for infants with cleft lip with or without cleft palate. This exploratory study compared test-retest and interrater reliabilities to inform whether differences in caregiver perspective might affect the iCOO.

Objective: We evaluated the measurement properties for item and domain scores of the Infant with Clefts Observation Outcomes Instrument (iCOO).

Design: Cross-sectional (before lip surgery) and longitudinal study (preoperative baseline and 2 days and 2 months after lip surgery).

Setting: Three academic craniofacial centers and national online advertisements.

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.

Objective: To develop an outcomes instrument that assesses observations that can be reliably reported by caregivers and can be used to assess health of infants with a cleft lip or cleft lip and cleft palate (CL±P) and impacts of treatments.

Design: Cross-sectional, mixed methods study.

Setting: Caregivers and health-care providers were recruited from 3 academic craniofacial centers and national advertisements.

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.

Objective: The Craniofacial microsomia: Longitudinal Outcomes in Children pre-Kindergarten (CLOCK) study is a longitudinal cohort study of neurobehavioral outcomes in infants and toddlers with craniofacial microsomia (CFM). In this article, we review the data collection and methods used to characterize this complex condition and describe the demographic and clinical characteristics of the cohort.

Objective: To explore, using semistructured qualitative interviews, parent observations of their infant's health as they relate to having a cleft lip or cleft lip and cleft palate (CL±P) and/or associated treatments.

Design: Cross-sectional, qualitative study across 3 sites.

Setting: Parents were recruited from 3 academic craniofacial centers.

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).

Purpose: The purpose of this study was to determine whether language skills differed between children with cleft palate or cleft lip and palate (CP±CL) who were adopted into an English-speaking home from a non-English-speaking country (late English exposure [LE]) and children with CP±CL raised from birth in an English-speaking home (early English exposure [EE]).

Method: Children (51 LE, 67 EE), ages 3;0 (years;months) to 9;0, completed the Clinical Evaluation of Language Fundamentals (CELF), Preschool Second Edition or Fourth Edition. Linear regression analysis was used to assess the impact of age of adoption and time in an English-speaking home on language skills, as measured by the CELF-P2 and CELF-4.

Cleft lip and/or palate (CL/P) are among the most common of all birth defects. Habilitation requires multiple surgeries and other therapies throughout childhood and adolescence. While multidisciplinary care is recommended, there is a great deal of variation in treatment protocols for this condition.

OBJECTIVE Single-suture craniosynostosis (SSC), the premature fusion of a cranial suture, is characterized by dysmorphology of the craniofacial skeleton. Evidence to suggest that children with SSC are at an elevated risk of mild to moderate developmental delays and neurocognitive deficits is mounting, but the associations among premature suture fusion, neuroanatomy, and neurocognition are unexplained. The goals of this study were to determine 1) whether differences in the brain are present in young children with the 2 most common forms of SSC (sagittal and metopic) several years following surgical correction, and 2) whether the pattern of differences varies by affected suture (sagittal or metopic).

Background: Previous research has observed higher than average rates of behavior problems in school-age children with single-suture craniosynostosis. However, most studies used a single informant (mothers) and did not include comparison groups to control for sociodemographic factors.

Methods: The authors gave standardized behavior checklists to the mothers, fathers, and teachers of 179 elementary school children with single-suture craniosynostosis and 183 controls.

Objective: Previous studies have shown that infants and young children with single-suture craniosynostosis (SSC) perform more poorly on tests of visuomotor function than children without SSC. However, previous studies are limited by small sample sizes and little is known about the persistence of visuomotor problems into the school-age years. The aim of this study was to compare visuomotor function in children with and without SSC at the beginning of elementary school.
