Patients with cleft lip and palate sometimes have a retruded maxilla. Here, we describe the case of a young man in whom crowding of the maxillary teeth and an anteroposterior discrepancy of the maxilla were resolved by premaxillary distraction osteogenesis (DO) using 3 individual intraoral distractors. Our experience in this patient confirms that premaxillary DO with 3 intraoral distractors and preoperative simulation can achieve stable maxillary advancement and arch expansion without impairing velopharyngeal incompetence.
唇腭裂患者有时会出现上颌后缩。在此，我们描述一例年轻男性患者的病例，该患者通过使用3个单独的口腔内牵张器进行前颌骨牵张成骨术（DO），解决了上颌牙齿拥挤和上颌前后向差异的问题。我们对该患者的经验证实，使用3个口腔内牵张器进行前颌骨DO和术前模拟可以实现稳定的上颌前徙和牙弓扩展，而不会损害腭咽功能不全。
