In some severe skeletal Class III patients, mandibular setback surgery using sagittal split ramus osteotomy (SSRO) is performed to correct mandibular protrusion. However, in patients diagnosed with obstructive sleep apnea syndrome (OSAS), the risk of OSAS worsening as a result of the SSRO is very high. Maxillary advancement could reduce the degree of mandibular retropositioning and expand the skeletal framework in the pharyngeal region, leading to enlargement of the airway. However, nasal deformity is an undesirable outcome of the procedure. This case report describes a 23-year-old man with a retruded maxilla and OSAS. The maxillary retrusion was treated using Le Fort I osteotomy with an alar cinch suture and a muco-musculo-periosteal V-Y closure (ACVY). After treatment, better occlusal relationships and improvement in OSAS were observed. Thus, an ACVY could minimize nasolabial deformity.
在一些严重的骨骼 III 类患者中,采用矢状劈开下颌升支截骨术(SSRO)进行下颌后退手术以矫正下颌前突。然而,对于被诊断为阻塞性睡眠呼吸暂停综合征(OSAS)的患者,SSRO 导致 OSAS 恶化的风险非常高。上颌前突可减少下颌后缩的程度,并扩展咽腔的骨骼框架,从而扩大气道。然而,鼻畸形是该手术的不良后果。本病例报告描述了一位 23 岁的男性患者,上颌后缩,患有 OSAS。采用 Le Fort I 截骨术联合鼻翼紧缩缝线和黏膜-肌-骨膜 V-Y 关闭术(ACVY)治疗上颌后缩。治疗后,观察到更好的咬合关系和 OSAS 的改善。因此,ACVY 可以最大限度地减少鼻唇畸形。
