Abstract:
Oral findings in a case of Noonan syndrome in an 8-year-old Japanese male are reported. Examination of the patient revealed a narrow, high-arched palate and an anterior open bite. Cephalometric measurements showed a wide gonial angle, a large mandibular plane angle, a large Y-axis and long facial height. It is suggested that the patient had a skeletal open-bite malocclusion, which included an abnormal swallowing habit.
