三角形

This paper investigated the true propagation paths of acoustic wave in two-dimensional temperature gradient field-single peaked symmetry and deflective respectively, using the two- dimensional acoustic ray tracing method of forward deploying triangle. Besides, a simulating calculation and analysis of this acoustic ray tracing algorithm in model temperature was given.

Methods Design two incisions at canthus, one is short and horizontal just at the new point of canthus, the other is along eyelid fold about 5～4mm away from the short one. Transverse the horizontal incision into vertical by breaking or excising fibromuscular band under epicanthal skin and fixing canthus ligment on the lateral nasal aponeurosis.

在新内眦点处设计一小横切口，而重睑切口近内眦与横切口不贯通，保留切口之间的皮肤5～4mm，充分离断或去除部分眼轮匝肌、内眦韧带内向固定，切口经张力变形转向后，去除下部多余的三角形皮肤，将两切口间保留的皮肤整理埋入重睑皱褶内。
