Maxillary transverse deficiency is one of the most common deformities among occlusal discrepancies. Typical surgical methods are segmental Le Fort I osteotomy and surgically-assisted rapid maxillary expansion (SARME). This patient underwent a parasagittal split with a Le Fort I osteotomy to correct transverse maxillary deficiency. During follow-up, early transverse relapse occurred and rapid maxillary expansion (RME) application with removal of the fixative plate on the constricted side was able to regain the dimension again. RME application may be appropriate salvage therapy for such a case.
上颌横向发育不足是咬合紊乱中最常见的畸形之一。典型的手术方法是节段性Le Fort I截骨术和外科辅助快速上颌扩弓术(SARME)。该患者接受了Le Fort I截骨矢状劈开术以纠正上颌横向发育不足。在随访期间,出现了早期横向复发,通过在缩窄侧去除固定板并应用快速上颌扩弓术(RME),能够再次恢复其尺寸。对于这种情况,应用RME可能是合适的挽救治疗方法。
