Abstract
Macroglossia and abnormal posture of the tongue are considered to be etiological factors that lead to skeletal openbite. Furthermore, both factors influence the stability after orthognathic surgery. This is a case report of an 18-year-old male patient with anterior open-bite and mandibular prognathism. He underwent surgical orthodontic treatment combined with mandibular body ostectomy and glossectomy. No relapse was observed after a mandibular counterclockwise rotation procedure.
