In this article we discussed the work-up necessary to evaluate a patient for maxillary transverse deficiency, and the three treatments for maxillary transverse deficiency-SDE, RME, and SA-AME. Slow dentoalveolar expansion is used mostly in the primary and early mixed dentition. Rapid maxillary expansion is indicated most often in the mixed dentition and can be attempted in the early adult dentition. Surgically assisted-rapid maxillary expansion is applicable almost exclusively in the adult dentition. The treatment of choice will depend on the age and skeletal maturity of the patient. Surgically assisted-rapid maxillary expansion, the technique that is used at The Medical College of Pennsylvania, combines all aspects of the previously mentioned osteotomies. The maxilla is separated at the midpalatal, the maxillary buttress, and the pterygomaxillary sutures. We have experienced good outcomes and stability with this technique. The reviewed literature shows good results with SA-RME for the treatment of maxillary transverse deficiency in the adult patient. It would be beneficial to study relapse and the periodontal ramifications of maxillary expansion further to better define the indications for SDE, RME, and SA-RME.
在本文中，我们讨论了评估上颌横向发育不足患者所需的检查步骤，以及上颌横向发育不足的三种治疗方法——慢速牙牙槽扩展（SDE）、快速上颌扩展（RME）和外科辅助快速上颌扩展（SA-AME）。慢速牙牙槽扩展主要用于乳牙期和早混合牙列期。快速上颌扩展最常用于混合牙列期，也可尝试用于成人早期牙列期。外科辅助快速上颌扩展几乎仅适用于成人牙列期。治疗方法的选择将取决于患者的年龄和骨骼成熟度。宾夕法尼亚医学院所采用的外科辅助快速上颌扩展技术，结合了上述截骨术的各个方面。上颌在腭中缝、上颌支柱和翼上颌缝处分离。我们采用该技术取得了良好的效果和稳定性。综述文献表明，外科辅助快速上颌扩展治疗成人上颌横向发育不足效果良好。进一步研究上颌扩展后的复发情况及牙周影响，将有助于更好地明确慢速牙牙槽扩展、快速上颌扩展和外科辅助快速上颌扩展的适应证。
