The authors present their experience of maxillo-mandibular osteotomies performed at the Charles Nicolle Hospital in Tunis. The objective of this paper is to describe the preliminary steps (clinical, radiographic, photographic, modelling, cephalometric) in order to obtain a precise diagnosis of the dysmorphosis. They use Burstone's cephalometric analyses which allow evaluation of the relations between soft tissues which do not correspond to the relations of bony and dental displacement. They also present several clinical cases, the pre-operative steps and, most importantly, Burstone's cephalometric analyses demonstrating that, after osteotomies, the cephalometric values for soft tissues approach normal values. Complete analysis of the naso-maxillary profile may correct the motivation for consultation in some cases. The indication for Lefort I osteotomy is sometimes more appropriate than rhinoplasty. Preoperative orthodontic preparation is often required. Functional rehabilitation is necessary to adapt the orofacial muscles to the new shapes of the dental arch and to prevent recurrence.
作者介绍了他们在突尼斯查尔斯·尼科勒医院进行上颌-下颌截骨术的经验。本文的目的是描述初步步骤（临床、影像学、摄影、模型制作、头影测量），以便对畸形进行精确诊断。他们使用伯斯顿头影测量分析法，该方法可评估软组织之间的关系，而这些关系与骨和牙移位的关系并不对应。他们还展示了几个临床病例、术前步骤，最重要的是，伯斯顿头影测量分析表明，截骨术后软组织的头影测量值接近正常值。对鼻上颌轮廓的全面分析在某些情况下可能会纠正咨询的动机。勒福Ⅰ型截骨术的适应证有时比隆鼻术更合适。术前通常需要进行正畸准备。功能康复对于使口面部肌肉适应牙弓的新形状并防止复发是必要的。
