Abstract
Facial growth in a sample of 439 males with unilateral complete cleft lip and palate was evaluated. There were 213 subjects with some form of alveolus repair and 226 subjects with no alveolus repair. The results indicated that surgical repair of the alveolus in unilateral cleft lip and palate resulted in a deficiency in the vertical growth of the anterior max-illa. If, in addition, a bone graft or periosteoplasty was used, the vertical growth deficiency was slightly worse and lower face height was greater, so that facial vertical proportions were poor. There was also a slight anteroposterior maxillary deficiency following bone grafting. Late bone grafts in the mixed dentition have the same vertical effect as the. infant bone grafts. These findings should be applied to individuals at risk for poor facial growth.
