Congenital macroglossia: surgical and orthodontic management

ObjectivesA case of congenital macroglossia is reported. The most important sign of macroglossia is tongue protrusion through the lips. Tongue protrusion might influence skeletal growth and can cause anterior open bite, proclination of upper and lower incisors and development of diastemas.Materials and methodsA 4 year-old female patient was diagnosed with congenital macroglossia. Parents referred an abnormal tongue dimension since birth and the development of a progressive anterior open bite. The treatment of macroglossia included tongue reduction by partial glossectomy. She was seen regularly and at the age of eight years old a lingual frenectomy was performed and an orthodontic treatment was planned.ResultsAt the end of the orthodontic treatment a Class I occlusion was obtained with correct overbite and overjet values.ConclusionsEarly interception of macroglossia and surgical reduction in combination with orthodontic treatment can be seen as preventive measures to avoid the tongue influence on the development of malocclusions.
