A report of behavioral data on three groups of patients with craniofacial disorders.

Longitudinal follow-up data on development and school placement are presented for three groups of patients. Having had or not having had early surgical intervention and stimulation distinguishes the two groups of patients with craniosynostosis. The third group is patients with cleft lip and palate who received early intervention but did not achieve minimal criteria for communication by age 22 months. Educational placement (for patients 8 to 20 years of age) follows the pattern of distribution of students nationally for patients who had early intervention.
