[Glossoplasty: hope and pre-orthodontic support?].

A sample of 30 children who were between 8 and 15 years old is used for this study. The first part, using a cephalometric study (with two analysis: Ricketts and Sassouni), of these children's facial type, try to explain what expected the orthodontist after a partial resection of the tongue before treatment. In a second part, dental and skeletal effects of this surgery are studied, during a short period (5 to 10 months) before the beginning of the orthodontic treatment. These results are discussed according to research works realized by different authors.
