title: Hypoglossia: case report and discussion.
abstract: A case of hypoglossia was observed between the ages of 3 and 15 years in a patient with micrognathia, congenital absence of three lower incisors, and a telescopic occlusion accompanied by an extremely narrow lower arch and severe overbite. Orthodontic intervention was begun when the patient was 8 years old. Craniofacial growth changes that occurred before and after orthodontic treatment are discussed. Cephalometric study of this case suggests the distinctive features of the postnatal growth pattern similar to other cases with the syndrome.
