概括
按时针方向 (CW) 的上旋转减少了在整形外科手术中的下膜暴露 (ISE). 然而,垂直重新定位,而不是斜旋转,独立地预测了ISE的变化.
科学领域:
- 整形手术 整形手术 整形手术
- 面外科手术 面外科手术
- 整形外科 整形外科 整形外科
- 眼镜塑料是一种眼镜塑料.
背景情况:
- 低膜暴露 (ISE) 显著影响面部美学和和.
- 虽然研究了线性大运动,但对萨吉塔平面旋转向量对ISE的影响不太清楚.
研究的目的:
- 量化沙吉塔平面大旋转变化与LeFort I骨切除术后ISE之间的关联.
主要方法:
- 对42名因三级大缺陷而接受LeFort I骨切除术的患者进行了回顾性队列研究.
- Sagittal Occlusal 平面旋转 (顺时针 [CW]和反时针 [CCW]) 是主要的预测因素.
- 通过使用垂直瞳孔-下眼距离和可见膜区域测量,在手术前和手术后评估了ISE变化.
主要成果:
- CW旋转与ISE在统计学上显著下降有关 (P = .005-.041).
- 在CCW旋转时没有观察到显著的IEE变化.
- 萨吉塔旋转大小与ISE变化没有相关性 (r = -0.12至 -0.15;P = .5-.9).
- 垂直大的重新定位仍然是缩缩的重要预测因子 (P = .02),而角旋转不是一个独立的预测因子.
结论:
- 单变量分析显示,CW大旋转与减少的ISE相关.
- 垂直重新定位成为ISE变化的重要独立预测因素.
- 对多个向量组件的全面考虑对于虚拟直角手术规划至关重要.

01:28Angle Closure Glaucoma: Treatment
1.5K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

1.6K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
