Objective: This study sought to determine the timing of alveolar bone grafting (ABG) surgery among children with cleft lip with or without cleft palate (CL±P) with regard to race and insurance status.

Design: A retrospective chart review of consecutive patients receiving ABG surgery was conducted. A multivariate regression model was constructed using predetermined clinical and demographic variables.

Of the 261 nonsyndromic patients we studied, over 90% had minimal or absent hypernasality, almost 86% had inconsistent or no nasal emission, and 95% had no articulation errors related to velar function. The patients with a Pittsburgh score indicating an incompetent velopharyngeal mechanism comprised only about 6% of the group. Ninety-four percent had a socially functional speech quality.

To determine whether the autosomal dominant fibroblast growth factor receptor 3 (FGFR3) Pro250Arg mutation causes anterior plagiocephaly, patients with either apparently sporadic unicoronal synostosis (N = 37) or other forms of anterior plagiocephaly (N = 10) were studied for this mutation. Of 37 patients with unicoronal synostosis, 4 tested positive for the Pro250Arg mutation in FGFR3, and 33 were negative for this mutation. In three mutation positive patients with full parental studies, a parent with an extremely mild phenotype was found to carry the same mutation.

This retrospective study compares the success of iliac versus cranial bone autografts in the secondary grafting of alveolar clefts. The study group was 116 patients with complete records and radiographs from a pool of 186 consecutively grafted patients at Children's Hospital of Philadelphia. The quality of graft "take" was graded radiologically.

In conclusion, the management of facial involvement in JRA, Romberg disease, and scleroderma is dictated by the degree of severity of the disease, age of onset, and length of activity. Functional occlusal abnormalities are best addressed through a team approach consisting of initial orthodontics followed by orthognathic surgery if needed. In all types of scleroderma, surgical facial reconstruction is best delayed until the disease is quiescent for at least a year.
