概括

大巴复合体 (MMC) 的时针旋转 (CWR) 显著改善了巴前曲率 (FLC) 和下骨高在巴前症患者中. 这种CWR通过创造更有利的向上唇曲线来增强面部美学.

科学领域:

整形手术整形手术整形手术
面部美学面部美学
面外科手术面外科手术

背景情况:

优化面部美学需要了解orthognathic手术后的软组织变化.
骨III类缺陷在实现平衡的面部形状方面存在挑战.

研究的目的:

为了分析面部软组织的变化后顺时针旋转 (CWR) 的上部复合体 (MMC).
为了评估CWR对前唇曲率 (FLC) 的影响,在手术第一方法治疗下前症的患者中.

主要方法:

前性队列研究比较CWR患者 (封闭平面变化>4°) 和对照组 (封闭平面变化≤4°).
面部变化在手术前 (T0) 和 ортодонтика解锁后 (T1) 进行评估.
统计分析包括曼·惠特尼U,配对t测试,独立t测试,奇平方测试和后勤回归.

主要成果:

在CWR组显示显著增加的FLC,警报宽度,和较低的红的高度,以及下唇的长度下降.
高的FLC与上唇投射的减少和鼻角的增加有关.
CWR和改善的FLC之间的关系在统计学上是显著的.

结论:

增加CWR的MMC积极影响FLC和较低的红身高,同时减少下唇的长度.
上唇曲线的向上运动,由高FLC表示,有助于改善面部美学.
