Maxillary posterior hyperplasy is a frequent dento-facial deformity. A dento-alveolar origin seems to be more frequent than a squelettic one; in our experience, there is a direct relationship between the volume of the tongue and the open bite--surgical correction was done with a LE FORT 1 osteotomy and a tongue reduction was done simultaneously in half of the patients--a sliding genioplasty sometimes was done to improve the profile--for us, post chirurgical relapse was frequent with patients without tongue reduction.
上颌后牙区增生是一种常见的牙颌面畸形。牙牙槽源性似乎比骨骼源性更为常见；根据我们的经验，舌体积与开牙合之间存在直接关系——一半的患者采用勒福Ⅰ型截骨术进行手术矫正并同时进行舌缩减术——有时进行颏成形术以改善侧貌——对我们来说，未进行舌缩减术的患者术后复发很常见。
