Micrognathia after radiation therapy for childhood facial tumors. Report of two cases with long-term follow-up.

As the survival duration and cure rate of children with malignant conditions improve, awareness of long-term side effects is crucial. Two case reports demonstrate long-term changes in dentition and orofacial development in children who had been treated for facial malignant conditions. Changes induced mandibular and maxillary hypoplasia, partial anodontia, microdontia, altered eruption pattern, root stunting, and altered amelogenesis.
